Hole in a Tooth — What Should You Do?

A hole in a tooth doesn’t fix itself. The longer it’s left, the more complex and costly the treatment becomes.

Discovering a hole in your tooth — whether you feel it with your tongue, notice it in the mirror, or a dentist points it out — is one of those moments where the temptation to wait and see is strong. Resist it. Tooth decay is a progressive disease. What is a small filling today becomes a large filling tomorrow, a crown next year, and potentially a root canal or extraction the year after that.

What causes a hole in a tooth?

A hole — clinically called a cavity or carious lesion — is the physical result of tooth decay. The process begins long before the hole appears.

Bacteria in the mouth, primarily Streptococcus mutans, feed on fermentable carbohydrates — sugars and refined starches — and produce acid as a byproduct. This acid demineralises enamel, progressively softening and dissolving tooth structure. Initially the damage is microscopic and reversible with fluoride and good oral hygiene. Once the enamel surface breaks down entirely, a physical cavity forms — and at that point the damage cannot be reversed without intervention.

The most common sites for cavities are the biting surfaces of back teeth, where deep fissures trap bacteria and food; the contact points between teeth, where flossing is the only effective cleaning method; and the exposed root surfaces of teeth with gum recession, which have no enamel protection.

What does a hole in a tooth feel like?

Not all cavities are symptomatic — particularly in their early stages. Many are discovered at routine check-ups through clinical examination and X-rays before the patient has felt anything at all. This is one of the strongest arguments for regular dental visits: catching decay before it becomes painful is always better than waiting for pain to drive the appointment.

When symptoms do occur they typically follow this progression:

  • Sensitivity to sweet foods and cold — early dentine involvement
  • Lingering cold sensitivity — decay approaching the pulp
  • Spontaneous aching or throbbing — pulp inflammation, indicating significant depth
  • Sensitivity to heat, or pain that wakes you at night — irreversible pulpitis, requiring root canal treatment or extraction
  • Swelling, abscess, or a pimple on the gum — infection has spread beyond the tooth

Pain is not a reliable indicator of severity. A tooth can have extensive decay with no symptoms at all until the pulp is involved. Conversely, a relatively small cavity in a sensitive location can be acutely painful. Clinical and radiographic assessment is the only reliable way to determine what is actually happening.

What happens if you leave a hole in a tooth untreated?

Decay does not stabilise without treatment. The bacterial process continues, the cavity deepens, and the structural integrity of the tooth progressively diminishes. The clinical consequences of delay follow a predictable path:

Small cavity in enamel or superficial dentine → simple filling, completed in one appointment, minimal cost, tooth fully preserved.

Moderate cavity in deeper dentine → larger filling or possible onlay, more tooth structure removed, higher cost, some risk of sensitivity post-treatment.

Deep cavity approaching or involving the pulp → root canal treatment or extraction. Root canal treatment preserves the tooth but requires multiple appointments and subsequent crown placement in most cases. Extraction removes the problem but creates a gap that requires management — implant, bridge or denture — to prevent adjacent teeth drifting and opposing teeth over-erupting.

Dental abscess → urgent treatment, possible hospital admission in severe cases, risk of spreading infection to jaw, neck and beyond. Dental infections, while rarely life-threatening in healthy adults, can become serious rapidly in immunocompromised individuals.

The cost — financial, biological and in treatment complexity — escalates at every stage. A filling placed early costs a fraction of what root canal treatment and a crown costs later.

How Tooronga Family Dentistry treats cavities

Small to moderate cavities — tooth-coloured composite fillings We use tooth-coloured composite resin for the vast majority of fillings. Modern composite is strong, aesthetically natural, and requires less removal of healthy tooth structure than the amalgam fillings of previous decades. For patients across Glen Iris, Malvern and Hawthorn who have old silver amalgam fillings they’d like replaced for aesthetic or health reasons, composite replacement is a straightforward option we discuss at consultation.

The procedure is straightforward: local anaesthesia, removal of decayed tissue, conditioning of the tooth surface, placement and shaping of composite resin in layers, curing with a light, and final polishing. Most fillings are completed in a single appointment of 30 to 60 minutes.

Large cavities — onlays and crowns When decay has destroyed a significant portion of tooth structure, a filling alone may not provide adequate strength or longevity. An onlay — a laboratory-fabricated restoration bonded to the remaining tooth structure — or a full crown may be recommended. These restorations are more durable for heavily broken-down teeth and distribute biting forces more effectively than large direct fillings.

Deep cavities near the pulp — protective measures When decay is deep but the pulp has not been directly exposed, we place a protective liner or base beneath the filling to promote pulp recovery and reduce the risk of post-operative sensitivity. In some cases a tooth requires monitoring after a deep filling to confirm the pulp remains healthy before a final restoration is placed.

Root canal treatment Where the pulp is irreversibly inflamed or infected, root canal treatment removes the pulp tissue, disinfects the root canal system, and seals the tooth. Modern root canal treatment at Tooronga Family Dentistry is performed under local anaesthesia and is significantly more comfortable than its reputation suggests. The majority of patients report the procedure as no more uncomfortable than a routine filling.

Emergency care for painful cavities We understand dental pain doesn’t follow business hours. If you are experiencing acute toothache from a cavity — particularly spontaneous pain, throbbing, or pain that prevents sleep — contact us as a priority. We accommodate urgent appointments for patients across Glen Iris, Malvern, Hawthorn, Hawthorn East and Ashburton.

What you can do right now

If you’ve noticed a hole in a tooth, the single most useful thing you can do is book a dental appointment promptly. In the meantime:

  • Avoid very hot, cold, or sweet foods that trigger pain
  • Keep the area clean — don’t avoid brushing a decayed tooth for fear of pain
  • If the cavity has a sharp edge catching your tongue or cheek, temporary dental cement from a pharmacy can provide short-term protection while you wait for your appointment
  • Take paracetamol or ibuprofen at recommended doses for pain relief — clove oil applied to the cavity can provide additional temporary relief
  • Do not place aspirin directly on the gum or tooth — this causes chemical burns to soft tissue

Prevention — making the next cavity less likely

Once decay has been treated, attention turns to preventing recurrence. At Tooronga Family Dentistry we don’t simply fill and farewell — we review why the cavity developed and address those factors directly.

  • Fluoride treatments applied in-chair strengthen enamel and dramatically reduce cavity risk
  • Fissure sealants on back teeth with deep grooves prevent bacteria and food from becoming trapped in the highest-risk sites
  • Dietary review — identifying the frequency and timing of sugar exposure in your diet
  • Oral hygiene instruction — ensuring brushing technique and interdental cleaning are genuinely effective
  • Regular check-ups and X-rays — catching the next lesion before it becomes a cavity

Found a hole in your tooth or experiencing toothache? Don’t wait. Book an appointment at Tooronga Family Dentistry — we provide prompt, thorough care for patients across Glen Iris, Malvern, Hawthorn, Hawthorn East and Ashburton.

Blog 15: Sudden Sharp Pain When Chewing — What Is It and What Should You Do?

Sharp pain when you bite down is one of those symptoms that’s hard to ignore — and shouldn’t be.

A sudden, sharp pain when chewing is your tooth signalling that something is structurally or biologically wrong. Unlike the dull ache of a developing cavity or the generalised sensitivity of enamel erosion, pain specifically triggered by biting or chewing is highly localised and diagnostically meaningful. It narrows the possible causes considerably — and most of them require professional assessment rather than watchful waiting.

Why biting causes pain — the underlying mechanics

When you chew, you apply significant force through your teeth — the average bite force on a molar is between 400 and 800 newtons. In a healthy tooth this force is distributed evenly through intact tooth structure and absorbed by the periodontal ligament — the fibrous tissue suspending the tooth in its socket. Pain occurs when this force encounters a structural defect, an inflamed ligament, or an exposed nerve — concentrating stress in a way that triggers an acute pain response.

The most common causes of sharp pain when chewing

Cracked tooth syndrome The most common and frequently missed cause of sharp biting pain. A crack in a tooth — often invisible on X-ray and sometimes invisible to the naked eye — creates an unstable segment of tooth structure that flexes under biting load. This flexion stimulates the nerve acutely, producing a sharp pain that typically occurs on biting down and releases suddenly when pressure is removed. The pain on release is particularly characteristic of a cracked tooth.

Cracks most commonly affect back teeth and are strongly associated with large old fillings that have weakened surrounding tooth structure, grinding and clenching, and biting hard objects. Ice chewing is a surprisingly common precipitating factor.

The challenge with cracked tooth syndrome is that the crack may not be visible on X-ray, making diagnosis dependent on clinical testing — bite testing with a specialised instrument on individual cusps, transillumination with a bright light to reveal crack lines, and dye staining. An experienced clinician can usually identify the offending tooth and cusp with targeted testing.

Treatment depends on crack depth. A crack confined to enamel and dentine is typically managed with a crown, which holds the tooth together and prevents the crack propagating further. A crack extending into the pulp requires root canal treatment before the crown. A crack extending below the gumline into the root — a vertical root fracture — often cannot be saved and requires extraction.

A failing or fractured filling An old filling — particularly a large amalgam filling — can fracture or develop a crack in the surrounding tooth structure over time. The remaining tooth walls, unsupported and weakened, flex under load and produce sharp pain. Sometimes the fractured cusp is visible; sometimes it requires magnification to identify. Treatment typically involves replacing the filling with a crown or onlay to restore structural integrity.

Decay beneath an existing restoration Secondary decay — decay developing at the margin of an existing filling or crown — undermines the restoration and the tooth structure beneath it. Biting load applied to a compromised tooth produces pain. X-rays are usually diagnostic. Treatment involves removing the failing restoration, excavating the decay, and replacing with a new filling or crown depending on the extent of destruction.

Periodontal abscess or acute gum infection An abscess in the gum tissue or periodontal ligament causes exquisite sensitivity to biting — the inflamed ligament cannot absorb occlusal load normally. Unlike pulp-related pain, periodontal pain tends to be more constant, associated with visible swelling or a pimple on the gum, and often accompanied by a bad taste. The tooth is typically tender to touch on its side as well as to biting. Treatment involves draining the abscess, cleaning the periodontal pocket, and antibiotic therapy where indicated.

Reversible pulpitis Inflammation of the pulp — from deep decay, a recent filling, or trauma — can cause pain on biting before progressing to spontaneous aching. At this stage the inflammation may still be reversible with appropriate treatment. A recently placed filling that produces biting pain may simply require adjustment of the bite — a high filling concentrates occlusal force on the restored tooth and causes disproportionate discomfort.

Irreversible pulpitis and pulp necrosis When pulp inflammation progresses beyond the reversible stage, biting pain is typically accompanied by spontaneous aching, sensitivity to heat that lingers, and eventually the development of an abscess. This requires root canal treatment or extraction — not a wait-and-see approach.

Dentine hypersensitivity at a specific tooth Localised enamel loss or root exposure at a single tooth can produce sharp pain with certain foods or biting pressures. This is typically less severe than crack-related pain and more consistently triggered by specific stimuli — cold, sweet, or acidic — rather than pure biting force.

Loose crown or broken tooth A crown that has lost its cementation moves fractionally under load, producing sharp pain or sensitivity. This is usually identifiable — the crown may feel slightly mobile or different under biting pressure. A loose crown requires re-cementation promptly; leaving it risks decay developing on the exposed tooth preparation underneath.

Diagnosing the cause — why this requires professional assessment

Sharp biting pain cannot be reliably self-diagnosed. Several of the causes above — particularly cracked tooth syndrome — are genuinely difficult to identify even clinically and require systematic testing. Attempting to diagnose by process of elimination at home wastes time and allows potentially serious conditions to progress.

At Tooronga Family Dentistry we use a structured diagnostic protocol for biting pain:

  • Detailed history — when does it occur, which tooth, biting down or releasing, hot or cold sensitivity, spontaneous pain
  • Visual examination with magnification and transillumination
  • Bite testing with a Tooth Slooth — isolating individual cusps to identify the exact site of pain
  • Percussion testing — tapping teeth to assess periodontal ligament involvement
  • Thermal testing — cold and heat to assess pulp status
  • Digital X-rays — assessing for decay, bone loss, abscess, and restoration integrity
  • Probing — assessing gum pocket depths around the affected tooth

This systematic approach almost always identifies the cause — even when the crack or defect is not immediately visible. The diagnostic appointment is the most important step.

Why you should not delay assessment

Sharp biting pain rarely resolves spontaneously. The underlying causes — cracks, decay, failing restorations, pulp inflammation — are progressive. A cracked tooth diagnosed and crowned early is saved. The same tooth left until the crack propagates into the root is extracted. A deep cavity causing biting pain that is treated now may need only a filling. Left until the pulp is involved it needs root canal treatment and a crown.

The window for conservative treatment is open now. It closes progressively with time.

Immediate measures while waiting for your appointment

  • Avoid chewing on the affected side
  • Avoid very hard foods — crusty bread, nuts, raw carrots — that concentrate biting force
  • Avoid temperature extremes if thermal sensitivity is also present
  • Take paracetamol or ibuprofen at recommended doses for pain management
  • Do not attempt to diagnose or treat by biting on something to identify the tooth — this risks propagating a crack further

Experiencing sharp pain when you chew? This is not something to monitor at home. Book an assessment at Tooronga Family Dentistry — we see patients from Glen Iris, Malvern, Hawthorn, Hawthorn East and Ashburton and have the diagnostic tools and clinical experience to identify the cause accurately and treat it promptly.

Why Do I Have Bad Breath Even After Brushing?

f your breath still isn’t fresh after brushing, the problem isn’t your technique — it’s the source, and brushing alone can’t reach it.

Bad breath after brushing is one of the most frustrating and socially distressing dental complaints. Most people respond by brushing more frequently, using stronger mouthwash, or consuming mints and gum in increasing quantities. None of these address the cause — and until the cause is identified and treated, the problem persists.

Why brushing alone is often insufficient

Toothbrushing cleans the smooth surfaces of teeth effectively. What it doesn’t adequately address is the bacteria living between teeth, beneath the gumline, on the back of the tongue, and in the deeper recesses of the mouth. These are precisely the environments where the bacteria responsible for bad breath thrive — anaerobic bacteria that produce volatile sulphur compounds (VSCs), the primary chemical cause of halitosis.

If your bad breath returns within an hour or two of brushing, the source is almost certainly in one of these areas.

The most common causes of persistent bad breath

The tongue — the most overlooked source The dorsal surface of the tongue — particularly the posterior third — is the single most common origin of bad breath. Its textured surface traps dead cells, food debris and bacteria in a biofilm that brushing teeth does nothing to address. A white, yellow or brown coating on the tongue is a direct visual indicator of this bacterial load. Tongue scraping, not brushing, is the most effective way to physically reduce it.

Gum disease Periodontal disease produces some of the most persistent and offensive breath of any dental condition. Bacteria colonising the pockets between teeth and gums produce VSCs continuously — and no amount of brushing or rinsing reaches bacteria embedded several millimetres beneath the gumline. If your gums bleed when you brush or floss, swell, or have receded, gum disease is likely contributing to your breath.

Food trapped between teeth Interdental spaces that aren’t flossed regularly accumulate decomposing food debris and bacteria. This produces a localised but potent source of odour that brushing simply redistributes rather than removes. Consistent daily flossing — or the use of interdental brushes — is essential.

Dry mouth (xerostomia) Saliva is the mouth’s primary self-cleaning mechanism. It flushes bacteria, neutralises acid, and maintains a pH environment that limits bacterial overgrowth. When saliva flow is reduced — through mouth breathing, certain medications, dehydration, or medical conditions — bacterial counts rise dramatically and breath deteriorates. Dry mouth is particularly pronounced in the morning, which explains why breath is typically worse upon waking.

Common medications that cause dry mouth include antihistamines, antidepressants, blood pressure medications, diuretics and many others. If you take regular medication and have persistent bad breath, this connection is worth exploring.

Poorly fitted or unclean dental appliances Dentures, retainers, mouthguards and aligners that are not cleaned thoroughly harbour bacteria and food debris. A denture worn overnight without cleaning is a significant source of odour. Partial dentures and retainers with metal clasps are particularly prone to bacterial accumulation in areas that are difficult to clean.

Old or failing dental work Fillings with failing margins, ill-fitting crowns, and old restorations with open contacts can trap food and bacteria in areas that routine brushing and flossing cannot reach. These act as persistent reservoirs of odour-producing bacteria.

Tonsil stones (tonsilloliths) Small calcified deposits that form in the crypts of the tonsils. They are composed of bacteria, dead cells and food debris and produce a distinctly unpleasant sulphurous odour. Many people are unaware they have them. Tonsil stones are not a dental problem — they require assessment by a GP or ENT specialist — but they are a surprisingly common cause of halitosis that persists despite excellent oral hygiene.

Sinus and post-nasal drip Chronic sinusitis, post-nasal drip and nasal polyps all contribute to bad breath. Mucus draining down the back of the throat provides nutrients for odour-producing bacteria. Morning breath is often worse in people with chronic sinus issues. Again, this requires medical rather than dental management.

Acid reflux (GERD) Gastro-oesophageal reflux disease causes stomach acid and partially digested food to move back into the oesophagus and sometimes the mouth. The resulting odour is distinctive and not addressable through oral hygiene alone. If you notice a sour or acidic taste alongside your bad breath, reflux may be a contributing factor worth discussing with your GP.

Systemic medical conditions Less commonly, persistent bad breath can signal systemic conditions including uncontrolled diabetes (which produces a sweet or fruity breath odour from ketones), kidney disease (ammonia-like breath), liver disease, and certain metabolic disorders. These are uncommon causes but worth considering when halitosis is severe, unexplained, and accompanied by other symptoms.

A complete oral hygiene routine that actually addresses halitosis

Brushing teeth twice daily is the starting point — not the complete solution. An effective routine for managing bad breath includes:

  • Tongue scraping morning and night — use a dedicated tongue scraper, not a toothbrush, which tends to redistribute rather than remove the biofilm
  • Interdental cleaning daily — floss or interdental brushes, reaching every space between teeth
  • Brushing along the gumline carefully — angling the brush at 45 degrees to the gumline to disrupt bacterial accumulation at and just below the margin
  • Staying well hydrated throughout the day to support saliva production
  • Cleaning all appliances — retainers, mouthguards and dentures cleaned daily with appropriate products
  • Antibacterial mouthwash as an adjunct — chlorhexidine-based rinses are the most evidence-backed for bacterial reduction, but should not be used long-term without professional guidance due to staining effects

How Tooronga Family Dentistry investigates and treats persistent bad breath

At our practice in Glen Iris we approach persistent halitosis methodically. A thorough assessment includes examination of gum health, probing of periodontal pockets, inspection of the tongue, review of restorations, assessment of saliva flow, and a detailed medical and medication history.

Many patients across Malvern, Hawthorn, Hawthorn East and Ashburton who present with persistent bad breath have never had a structured assessment — they’ve simply been managing the symptom. A single thorough appointment often identifies a treatable cause that has been present and unaddressed for years.

Why Are Teeth Sensitive to Hot or Cold?

That sharp, sudden pain when you sip hot coffee or bite into something cold is your tooth telling you something. The question is — what?

Tooth sensitivity to temperature is one of the most common dental complaints we see at Tooronga Family Dentistry, and one of the most misunderstood. Many people accept it as normal, manage it with sensitive toothpaste, and never investigate further.

Why teeth become sensitive to temperature

At the centre of every tooth is the pulp — a living tissue containing nerves and blood vessels. Surrounding it is dentine, a softer mineralised layer riddled with microscopic fluid-filled channels called dentinal tubules. Enamel covers the crown of the tooth, and cementum covers the root. Both act as insulating barriers.

When these barriers are compromised — through enamel loss, gum recession, cracks, or decay — dentinal tubules become exposed. Temperature changes cause the fluid inside these tubules to expand or contract, stimulating the nerve and producing that sharp, brief pain. The thinner the remaining barrier, the more pronounced the sensitivity.

The most common causes of temperature sensitivity

Enamel erosion Dietary acid from soft drinks, citrus, wine and vinegar gradually dissolves enamel, thinning the insulating layer over the dentine. Sensitivity from erosion tends to affect multiple teeth and worsens progressively without dietary and clinical intervention.

Gum recession When gums recede — through aggressive brushing, gum disease, or natural ageing — the root surface becomes exposed. Unlike the crown, roots have no enamel covering, only thin cementum. Exposed roots are acutely sensitive to both temperature and touch. Recession-related sensitivity is often localised to specific teeth.

Tooth grinding (bruxism) Grinding wears enamel from the biting surfaces and edges of teeth at an accelerated rate. Patients who grind often notice broad, generalised sensitivity across multiple teeth — particularly to cold. The wear pattern is typically visible clinically even when patients are unaware they grind.

Cracked tooth syndrome A crack in a tooth that doesn’t show on an X-ray can cause sharp, highly localised sensitivity — often to cold, and sometimes with a distinct pain on biting that releases suddenly when pressure is removed. This is one of the trickier diagnoses in dentistry, but an experienced clinician can identify it with targeted testing.

Tooth decay A cavity that has reached or is approaching the pulp produces sensitivity — initially to cold and sweet, and eventually to heat as well. Heat sensitivity that lingers after the stimulus is removed is a significant warning sign of pulp involvement requiring prompt assessment.

Recent dental treatment Sensitivity following a filling, crown preparation, or whitening treatment is common and usually temporary. The tooth has been disturbed and requires time to settle. If sensitivity from a recent procedure is worsening rather than improving after two to three weeks, review is warranted.

Gum disease Active periodontal disease causes bone and tissue loss around teeth, leading to root exposure and sensitivity. Treating the gum disease addresses both the infection and, in many cases, the sensitivity.

Receding fillings or leaking margins Old or worn fillings can develop gaps at their margins, allowing temperature, bacteria and fluid to reach the dentine beneath. This type of sensitivity is typically localised to one tooth with a specific restoration.

When sensitivity is a warning sign you should not ignore

Not all sensitivity is equal. These patterns require prompt dental assessment rather than watchful waiting:

  • Sensitivity to heat, or heat sensitivity that lingers after the stimulus is removed — this suggests pulp inflammation or infection
  • Spontaneous toothache with no stimulus
  • Sensitivity combined with visible swelling, a pimple on the gum, or a bad taste
  • Sensitivity in a single tooth that is progressively worsening
  • Pain on biting combined with cold sensitivity — possible cracked tooth

Prolonged heat sensitivity in particular is one of dentistry’s more urgent signals. It can indicate irreversible pulpitis — inflammation of the pulp that will not resolve without root canal treatment or extraction.

How we diagnose and treat sensitivity at Tooronga Family Dentistry

Diagnosing the cause of sensitivity requires clinical examination, targeted testing with cold and heat stimuli, bite testing, transillumination for cracks, and X-rays where indicated. We do not guess — we test systematically until the cause is clear.

Treatment depends entirely on the cause:

  • Fluoride application: In-chair fluoride varnish for erosion and generalised sensitivity — strengthens and partially remineralises exposed dentine
  • Dentine bonding agents: A thin layer of bonding resin sealed over exposed dentinal tubules for immediate and durable relief
  • Gum grafting: For significant recession exposing root surfaces — restores gum coverage and eliminates the underlying cause
  • Nightguard: Custom occlusal splint for grinding-related sensitivity — prevents further enamel loss while protecting restorations
  • Fillings or crowns: For decay, cracked teeth, or failing restorations contributing to sensitivity
  • Root canal treatment: Where the pulp is irreversibly inflamed or infected — eliminates the source of pain definitively
  • Dietary counseling: For erosion-driven sensitivity — identifying and modifying the acid load in your diet

We see patients across Glen Iris, Malvern, Hawthorn, Hawthorn East and Ashburton with sensitivity ranging from mild and manageable to severe and urgent — and the approach we take is always guided by an accurate diagnosis first.

Experiencing sensitivity to hot or cold? Don’t just mask it with sensitive toothpaste and hope it resolves. Book an assessment at Tooronga Family Dentistry — finding the cause is the only way to find the right solution.

Smile Makeovers in Glen Iris — Composite Bonding, Veneers and Cosmetic Dentistry

Your smile is one of the first things people notice. If you’ve been hiding yours, modern cosmetic dentistry offers more options than ever — and more affordably than most people expect.

A smile makeover isn’t a single procedure. It’s a personalised combination of treatments chosen to address your specific concerns — whether that’s chipped, worn, discoloured, uneven, or gapped teeth. At Tooronga Family Dentistry we take a conservative, considered approach: the least invasive treatment that achieves the result you’re looking for.

Composite Bonding

Composite bonding is one of the most versatile and accessible cosmetic treatments available. A tooth-coloured resin is applied directly to the tooth, sculpted by hand, and hardened with a curing light — all in a single appointment, with no drilling and no removal of healthy tooth structure in most cases.

Bonding is ideal for:

  • Chipped or fractured teeth
  • Worn edges from grinding or acid erosion
  • Small gaps between teeth (diastemas)
  • Slightly misshapen or uneven teeth
  • Discolouration that whitening cannot address
  • Exposed root surfaces causing sensitivity

What makes bonding exceptional value is the combination of immediate results, minimal intervention and relatively low cost compared to porcelain alternatives. The trade-off is longevity — composite resin is less durable than porcelain and more prone to staining over time, typically lasting five to eight years before requiring a refresh. For many patients this is an entirely acceptable trade-off, particularly as bonding can be repaired and updated incrementally as tastes and budgets change.

Porcelain Veneers

Veneers are thin shells of dental porcelain bonded to the front surface of teeth. They are the premium option in cosmetic dentistry — delivering outstanding aesthetics, exceptional durability, and a result that genuinely mimics the translucency and depth of natural tooth structure in a way composite cannot fully replicate.

Veneers are suited to patients who want:

  • A comprehensive, long-lasting smile transformation
  • Correction of more significant discolouration, including tetracycline staining
  • Uniform shape, length and alignment across multiple teeth
  • A result that holds its colour and polish for ten to fifteen years or more

The key consideration with traditional veneers is that a thin layer of enamel — typically 0.3 to 0.7mm — is removed from the tooth surface to accommodate the veneer. This makes the process largely irreversible, which is why the decision warrants careful consultation and planning.

Minimal-prep and no-prep veneers are an option in select cases where teeth are small or set back, allowing veneers to be placed with little or no enamel removal. We assess suitability for this approach individually.

Composite Veneers

A middle-ground option — the coverage of a veneer using composite resin rather than porcelain. Less expensive and fully reversible, but with the durability and stain-resistance limitations of composite. Suitable for patients who want a more complete aesthetic change than spot bonding but aren’t ready to commit to porcelain.

How a Smile Makeover Is Planned at Tooronga Family Dentistry

A smile makeover begins with a detailed consultation. We discuss what you like and dislike about your smile, review photographs, and assess your dental health, bite, and gum architecture. Cosmetic work on an unhealthy foundation produces poor results — gum health and bite stability are addressed first.

Where appropriate we use digital smile design tools and mock-ups — a provisional version of the proposed result placed directly on your teeth — so you can preview the outcome before any permanent work is undertaken. This step is invaluable for both patient confidence and precise communication between patient and dentist.

Combining treatments for optimal results

The most effective smile makeovers typically combine treatments. A common sequence for patients in Glen Iris and Malvern might be:

  • Professional whitening first — to establish the brightest baseline shade for surrounding teeth
  • Composite bonding or veneers to address shape, chips and any remaining discolouration
  • Gum contouring if the gumline is uneven and affecting smile symmetry
  • A nightguard if grinding is present, to protect the investment

Best Toothpaste for Sensitive Teeth in Australia

Tooth sensitivity is one of the most common dental complaints — but not all sensitive toothpastes work the same way.

That sharp, sudden pain when you drink something cold, bite into ice cream, or breathe in cold air is tooth sensitivity. It’s caused by exposed dentine — the layer beneath enamel — whose microscopic tubules connect directly to the nerve of the tooth. When these tubules are exposed, temperature, pressure and sweet or acidic stimuli travel rapidly to the nerve, triggering that characteristic brief but intense discomfort.

The right toothpaste can make a significant difference. But with a crowded market and heavy advertising, knowing which product actually works requires cutting through the noise.

How desensitising toothpastes work

There are two distinct mechanisms used in sensitive toothpastes:

1. Nerve desensitisation: Potassium nitrate and potassium citrate work by diffusing through dentinal tubules and stabilising the nerve, reducing its ability to transmit pain signals. These ingredients require consistent daily use over two to four weeks before results are felt — they are not immediate.

2. Tubule occlusion: Ingredients such as stannous fluoride, strontium acetate, hydroxyapatite and arginine physically block or plug the open dentinal tubules, reducing fluid movement and nerve stimulation. Some of these work more rapidly than potassium-based products.

The best sensitive toothpastes available in Australia

Sensodyne Repair & Protect Contains NovaMin (calcium sodium phosphosilicate), which deposits a hydroxyapatite-like layer over exposed dentine, physically repairing and occluding tubules. One of the most evidence-backed sensitive toothpastes available in Australia. Widely available at pharmacies and supermarkets.

Sensodyne Rapid Relief Uses stannous fluoride for faster tubule occlusion. As the name suggests, some patients notice relief within days rather than weeks. A strong option when faster results are the priority.

Colgate Sensitive Pro-Relief Uses an arginine and calcium carbonate formula that plugs dentinal tubules rapidly. Clinical studies show meaningful relief with a single application when applied directly to the sensitive tooth and rubbed in for one minute. Also provides ongoing protection with regular brushing.

Tooth Mousse (GC) Not strictly a toothpaste but worth including. A cream containing Recaldent (CPP-ACP — casein phosphopeptide-amorphous calcium phosphate), which remineralises and strengthens enamel and dentine. Particularly effective for erosion-related sensitivity and for patients undergoing whitening. Available through dental practices including Tooronga Family Dentistry.

Elmex Sensitive Professional Uses an arginine-based formula similar to Colgate Pro-Relief. Less widely known in Australia but well regarded clinically and available at most pharmacies.

What to look for on the label

When choosing a sensitive toothpaste in Australia, look for one or more of these active ingredients: potassium nitrate, potassium citrate, stannous fluoride, arginine, hydroxyapatite, or NovaMin. Also confirm the product carries adequate fluoride — at least 1000ppm — for ongoing decay prevention alongside desensitisation.

What to avoid

  • High-abrasivity whitening toothpastes if sensitivity is already present — these can worsen exposure of dentinal tubules over time
  • Charcoal toothpastes — typically high in abrasivity with no clinical evidence for sensitivity relief
  • Any product without fluoride — desensitisation without decay protection is an incomplete solution

An important caution

Sensitivity is a symptom, not a diagnosis. While desensitising toothpaste manages the symptom effectively for many patients, it does not address underlying causes such as gum recession, enamel erosion, cracked teeth, or early decay. If sensitivity is new, worsening, or affecting multiple teeth, a dental assessment is essential before assuming toothpaste alone is sufficient.

At Tooronga Family Dentistry we regularly see patients from Glen Iris, Malvern, Hawthorn and Ashburton who have been managing sensitivity with toothpaste for months without identifying the underlying cause. In some of these cases, more meaningful treatment — fluoride application, bonding, a nightguard, or gum treatment — produces far better outcomes than toothpaste alone ever could.

Gum Disease and Bad Breath — What’s the Connection?

Persistent bad breath is rarely about what you ate. More often, it’s a sign that something is happening beneath your gumline.

Bad breath — clinically known as halitosis — is one of the most common complaints in dental practice. While most people reach for mouthwash or mints, these only mask the symptom. If your bad breath keeps returning despite good oral hygiene, gum disease is the most likely cause and the one that most urgently needs attention.

Why gum disease causes bad breath

Gum disease begins when plaque — a sticky film of bacteria — builds up along and beneath the gumline. As the bacteria multiply in the warm, oxygen-poor pockets between teeth and gums, they produce volatile sulphur compounds (VSCs). These sulphur gases are the direct source of the characteristic unpleasant odour associated with gum disease.

In early-stage gum disease (gingivitis), the gums are inflamed and may bleed when brushed. At this stage the process is entirely reversible. Left untreated, gingivitis progresses to periodontitis — a deeper infection that destroys the bone and connective tissue supporting your teeth. The bacterial load, and the odour it produces, intensifies significantly at this stage.

How to tell if gum disease is behind your bad breath

  • Bad breath that persists despite brushing, flossing and rinsing
  • Gums that bleed when you brush or floss
  • Red, swollen or tender gums
  • Gums that appear to be pulling away from your teeth
  • A persistent bad taste in your mouth
  • Teeth that feel loose or have shifted position

Any one of these signs warrants a dental assessment. Several together suggest active gum disease that needs prompt treatment.

Other causes of bad breath worth knowing

Not all halitosis originates from gum disease. Dry mouth, certain medications, sinus infections, acid reflux and systemic conditions such as diabetes can all contribute. Tonsil stones and post-nasal drip are also common culprits. At Tooronga Family Dentistry we take a thorough history to identify the true source — because treating the wrong cause achieves nothing.

How we treat gum disease and eliminate the odour at its source

Scale and clean: Removal of plaque and calculus above and below the gumline. For many patients with early gum disease, this alone produces a dramatic improvement in breath and gum health.

Root planing (deep cleaning): For more advanced periodontitis, we clean the root surfaces of teeth beneath the gumline to remove bacteria embedded in deeper pockets. This allows the gum tissue to reattach and heal.

Ongoing periodontal maintenance: Gum disease is a chronic condition that requires ongoing management. We work with patients across Glen Iris, Malvern, Hawthorn and Ashburton on tailored maintenance schedules — typically three to four monthly cleans — to keep the disease under control and breath consistently fresh.

Antibacterial therapy: In some cases we use antibacterial rinses or locally applied antibiotics to reduce bacterial load in deep pockets.

What you can do at home

  • Brush twice daily, including carefully along the gumline
  • Floss daily — this is non-negotiable for gum health
  • Use an antibacterial mouthwash as an adjunct, not a substitute for brushing and flossing
  • Stay well hydrated to prevent dry mouth
  • Avoid smoking — smoking is one of the strongest risk factors for gum disease and independently causes bad breath
  • Attend regular professional cleans — home care alone cannot remove calcified deposits beneath the gumline

The important truth about mouthwash

Mouthwash temporarily reduces bacterial counts and masks odour, but it does not penetrate gum pockets or remove calculus. Using mouthwash to manage bad breath caused by gum disease is the equivalent of using air freshener to address a gas leak. It buys time but solves nothing.

Concerned about persistent bad breath or bleeding gums? Don’t ignore it. Call or book online an assessment at Tooronga Family Dentistry — we see patients from Glen Iris, Malvern, Hawthorn, Hawthorn East and Ashburton and can identify and treat the cause properly.

Enamel erosion is permanent. Understanding what causes it is the first step to stopping it.

Unlike tooth decay, which is caused by bacteria, enamel erosion is a chemical process — acid directly dissolving the mineral structure of your enamel. And unlike many dental problems, it is largely diet-driven, meaning the choices you make every day are either protecting or slowly destroying the hardest substance in your body.

What is enamel and why does it matter?

Enamel is the outer layer of your tooth — a crystalline, mineralised shield that protects the softer dentine beneath. It has no living cells, which means your body cannot regenerate it once it’s lost. Erosion is cumulative and irreversible. What’s gone is gone.

As enamel thins, teeth become sensitive to temperature and sweet foods, appear more yellow as the underlying dentine shows through, develop a translucent or glassy appearance at the edges, and become increasingly vulnerable to chipping and decay.

The most erosive foods and drinks

Acid erosion occurs when the pH in your mouth drops below 5.5 — the critical threshold at which enamel begins to dissolve. The lower the pH, the more aggressive the erosion.

  • Citrus fruits and juices — lemon, lime, orange and grapefruit juice are among the most erosive substances you can put in your mouth. Lemon juice has a pH of around 2.
  • Soft drinks and energy drinks — both regular and diet varieties are highly acidic. Diet versions are no safer for enamel than their sugary counterparts.
  • Sparkling water — mildly acidic due to carbonic acid. Less damaging than soft drinks but worth being aware of with frequent consumption.
  • Vinegar-based foods — salad dressings, pickles and kombucha are more acidic than most people realise.
  • Wine — both red and white wine are acidic, with white wine typically more erosive than red.
  • Sports drinks — frequently consumed during exercise when saliva flow is reduced, compounding their erosive effect.

How eating patterns matter as much as what you eat

The frequency of acid exposure is often more damaging than the total quantity consumed. Sipping a soft drink over two hours exposes your teeth to sustained acid attack. Drinking it in ten minutes and rinsing with water is significantly less damaging. Similarly, holding juice in your mouth, swishing drinks, or drinking acidic beverages last thing at night when saliva flow drops dramatically all accelerate erosion.

The role of saliva

Saliva is your mouth’s natural defence against acid. It neutralises acid, remineralises softened enamel, and buffers pH back toward neutral. This process takes approximately 30 to 60 minutes after an acid challenge — which is why brushing immediately after acidic food or drink actually causes more damage, not less. You are brushing softened, temporarily vulnerable enamel.

How Tooronga Family Dentistry identifies and manages enamel erosion

Early erosion is often invisible to patients but detectable clinically. At our practice in Glen Iris we assess enamel wear at every check-up, mapping changes over time to catch erosion before it becomes symptomatic.

Treatment and prevention options we offer:

  • Fluoride treatments: High-concentration fluoride applied in-chair strengthens and remineralises enamel, making it more resistant to future acid attack.
  • Fissure sealants and bonding: Where erosion has created sensitivity or structural vulnerability, tooth-coloured bonding can protect exposed dentine and restore contour.
  • Dietary counselling: We help patients across Malvern, Hawthorn, Hawthorn East and Ashburton identify their specific dietary acid load and make targeted, realistic changes.
  • Custom mouthguards: For patients who also grind their teeth, the combination of erosion and grinding accelerates tooth loss significantly. A custom occlusal splint protects what remains.
  • Monitoring and photography: We photograph and document erosion patterns so that progression — or stabilisation — can be tracked accurately over time.

Practical steps to protect your enamel today

  • Finish acidic meals with cheese or plain milk — both neutralise acid and promote remineralisation
  • Drink acidic beverages through a straw to reduce contact with teeth
  • Rinse with plain water immediately after acidic food or drink
  • Wait at least 30 minutes before brushing after acid exposure
  • Use a low-abrasion fluoride toothpaste — avoid harsh whitening toothpastes if erosion is already present
  • Chew sugar-free gum after meals to stimulate saliva flow
  • Stay well hydrated — a dry mouth has no acid buffer

With so many whitening options available, how do you know which one actually delivers results — safely?

Walk into any pharmacy and you’ll find strips, pens, toothpastes and kits all promising a brighter smile. Search online and the options multiply further. But not all whitening is equal — and in Australia, the regulatory landscape plays a significant role in what’s available, what works, and what’s worth your money.

How Australian regulations shape your whitening options

Australia’s Therapeutic Goods Administration (TGA) restricts the sale of hydrogen peroxide whitening products to the general public to a maximum concentration of 6%. This is a consumer safety measure — but it also means that over-the-counter products are significantly less powerful than what a dentist can legally prescribe and apply.

Products above 6% hydrogen peroxide — which deliver noticeably better and faster results — are only available through registered dental professionals. This single fact is the most important thing to understand when comparing whitening options in Australia.

The main whitening options available in Australia

1. In-chair professional whitening The gold standard for speed and results. A high-concentration peroxide gel is applied chairside, often activated with a light or laser, over one to two hours. You leave the appointment with teeth that are visibly and dramatically whiter. At Tooronga Family Dentistry we offer in-chair whitening for patients across Glen Iris, Malvern, Hawthorn and Ashburton who want immediate, significant results.

2. Dentist-prescribed take-home whitening kits Custom-fitted trays made from impressions of your teeth, combined with professional-strength whitening gel. Worn for one to two hours daily, or overnight, over two to three weeks. Results are comparable to in-chair whitening and many patients prefer this option for its flexibility. The custom trays are the critical difference from over-the-counter alternatives — they ensure even gel distribution and protect gums from irritation.

3. Combined in-chair and take-home The most comprehensive approach. An in-chair session delivers immediate results, followed by a take-home kit to consolidate and extend whitening. This is the preferred option for patients with more significant staining or those who want the longest-lasting outcome.

4. Over-the-counter whitening strips and kits Limited to 6% hydrogen peroxide in Australia. Can produce modest improvement in surface staining over several weeks of consistent use. Results are limited compared to professional options and ill-fitting trays increase the risk of gum irritation. Suitable for mild maintenance between professional treatments — not a replacement for them.

5. Whitening toothpastes Work through mild abrasion and low-concentration peroxides. Effective for preventing new surface stains from building up, but do not lift existing intrinsic staining. A useful daily maintenance tool, not a whitening treatment.

What about popular brands like Zoom and Philips?

Zoom whitening — now marketed under the Philips brand — is one of the most widely used in-chair whitening systems in Australia and globally. It uses a high-concentration hydrogen peroxide gel activated under a specialised light. It is effective, well-researched and widely available through dental practices. It is one of several reputable professional systems — the quality of assessment, preparation and aftercare provided by your dentist matters as much as the brand of system used.

So what is the best whitening in Australia?

For most patients, a dentist-prescribed take-home kit or a combined in-chair and take-home treatment delivers the best balance of results, safety, longevity and value. In-chair whitening alone is ideal when speed matters. Over-the-counter products have a role in maintenance but should not be the primary treatment for anyone seeking a meaningful change.

The most important variable is not the product — it’s the professional assessment that precedes it. Whitening works best when your teeth and gums are healthy, existing restorations are accounted for, and the treatment is tailored to your specific staining and sensitivity profile.

Teeth whitening is one of the most requested cosmetic dental treatments — but is it actually safe for your enamel?

It’s a fair question. Enamel is the hardest substance in the human body, but it’s also irreplaceable. Once it’s gone, it doesn’t grow back. So before whitening your teeth, it’s worth understanding exactly what whitening does — and what it doesn’t do.

How whitening works

Professional whitening uses hydrogen peroxide or carbamide peroxide as the active ingredient. These agents penetrate the enamel and break apart the carbon bonds in stain molecules embedded within the tooth structure. The stains are broken down; the enamel itself is not dissolved or removed.

This is a fundamentally different process from abrasive whitening — such as harsh whitening toothpastes or charcoal products — which physically scrub the enamel surface and can cause genuine, cumulative damage.

What the evidence says

Decades of clinical research consistently show that professional whitening, used at appropriate concentrations and for recommended durations, does not damage enamel structure. Studies examining enamel hardness, surface morphology and mineral content before and after whitening find no clinically significant changes.

The key phrase is professional whitening at appropriate concentrations. This is where the safety distinction lies.

What can go wrong — and how we prevent it

  • Sensitivity: The most common side effect. Peroxide temporarily increases enamel permeability, which can cause short-lived tooth sensitivity and mild gum irritation. This resolves within 24–48 hours in most cases. We manage this with desensitising agents applied before and after treatment.
  • Overuse: Excessive or unsupervised whitening — particularly with high-concentration over-the-counter products — can cause enamel dehydration and increased porosity over time. This is why professional supervision matters.
  • Pre-existing enamel erosion: If your enamel is already compromised from acid erosion or heavy grinding, whitening requires careful assessment first. At Tooronga Family Dentistry we examine your enamel health before recommending any whitening treatment.
  • Gum exposure: Ill-fitting trays from over-the-counter kits allow peroxide to contact gum tissue, causing irritation. Our custom-fitted trays are precision-made to protect your gums entirely.

Professional versus over-the-counter whitening

In Australia, over-the-counter whitening products are limited to 6% hydrogen peroxide — low enough to reduce risk but also significantly less effective. Professional in-chair whitening and dentist-prescribed take-home kits use higher concentrations, applied safely under clinical supervision, producing faster and more lasting results without compromising enamel integrity.

The bottom line

Professional teeth whitening, performed or prescribed by a dentist, is safe for enamel. The evidence is clear and the track record is long. The risks are real but manageable — and almost entirely avoidable with proper assessment and supervised treatment.

Love your morning coffee or evening red wine? Here’s how to keep your smile bright.

Coffee and red wine are two of the most common causes of tooth discolouration. Both contain tannins — naturally occurring compounds that bind to tooth enamel and leave a yellow or brownish film over time. The acidity in both drinks also roughens enamel microscopically, giving stains an even better grip.

The result: a smile that looks dull, stained, and older than it should.

Why do coffee and wine stain so effectively?

Tannins in coffee and wine attach to the protein pellicle — the thin film that naturally coats your teeth. Chromogens, the intensely pigmented molecules in both drinks, then bind to those tannins and embed into enamel over time. The more frequently you drink them, and the longer the liquid sits on your teeth, the deeper the staining.

What actually works to remove stains

1. Professional cleaning (scale and polish) The most immediate and effective first step. At Tooronga Family Dentistry, our hygienist removes surface stains that brushing simply can’t reach — restoring your natural tooth colour without any bleaching agents. Many patients in Glen Iris and Malvern are surprised how much brighter their teeth look after a professional clean alone.

2. Air polishing A fine jet of pressurised powder and water that gently blasts surface stains from enamel. Highly effective for coffee and wine staining with no abrasion to enamel.

3. Professional teeth whitening For staining that has penetrated beyond the surface, whitening is the most effective solution. We offer both in-chair whitening and take-home custom tray whitening — both of which lift intrinsic staining that cleaning alone cannot address. More on whitening safety in our next blog post.

What you can do at home

  • Rinse with water immediately after coffee or wine — it dramatically reduces staining
  • Use a whitening toothpaste with low abrasivity (look for a low RDA rating)
  • Drink cold coffee or wine through a straw to reduce contact with teeth
  • Wait 30 minutes after drinking before brushing — acid softens enamel temporarily
  • Maintain regular six-monthly check-ups and cleans

What doesn’t work

Charcoal toothpaste is heavily marketed but lacks evidence and can be overly abrasive. Lemon juice and bicarb soda home remedies risk enamel erosion. Oil pulling has no credible evidence for stain removal.
