Wisdom teeth (third molars) cause confusion for Glen Iris patients—should they be removed or left alone? At Tooronga Family Dentistry, Dr. Kaufman evaluates wisdom teeth regularly, understanding that wisdom teeth are the third molars and require individualized assessment. In our evolution the skull has increased and the jaws decreased in size. As a result some people never develop wisdom teeth while other people develop impacted wisdom teeth—creating modern complications. Understanding what impacted wisdom teeth are, knowing wisdom teeth removal vs monitoring options, recognizing wisdom teeth complications (infection, cysts, nerve damage), and getting expert wisdom teeth evaluation empowers Glen Iris patients to make informed decisions about their wisdom teeth.

What Are Wisdom Teeth? Evolution and Modern Problems

Wisdom Teeth Anatomy and Evolutionary Changes

Wisdom teeth are the third molars:

Wisdom teeth characteristics:

✓ Last teeth to develop (erupting ages 17-25—”age of wisdom,” hence name) ✓ Four wisdom teeth typically (upper left/right, lower left/right—one per quadrant) ✓ Located furthest back (behind second molars—most posterior teeth) ✓ Often problematic (modern jaws—insufficient space for wisdom teeth)

Why Wisdom Teeth Cause Problems: Evolutionary Mismatch

In our evolution the skull has increased and the jaws decreased in size:

Evolutionary changes affecting wisdom teeth:

Ancestral humans: ✓ Larger jaws (accommodating all 32 teeth including wisdom teeth) ✓ Coarse diet (requiring more chewing surface—wisdom teeth functional) ✓ Tooth wear (losing teeth early—wisdom teeth replacing worn molars)

Modern humans: ⚠ Smaller jaws (evolution, softer diet—reduced jaw size) ⚠ Same number of teeth (32 teeth genes unchanged—but less jaw space) ⚠ Wisdom teeth don’t fit (insufficient room—wisdom teeth impacting) ⚠ Better dental care (keeping teeth longer—wisdom teeth not needed as replacements)

The result:

⚠ Impacted wisdom teeth epidemic (60-70% of population—wisdom teeth unable to erupt normally) ⚠ Evolutionary lag (jaws evolving faster than tooth genes—wisdom teeth mismatch)

Wisdom Teeth Variability: Individual Differences

As a result some people never develop wisdom teeth:

Wisdom teeth development variations:

Complete agenesis (no wisdom teeth): ✓ 10-25% of population (never develop wisdom teeth—genetic variation) ✓ Ethnic differences (Mexican heritage 45% missing one+ wisdom teeth; African descent 11%) ✓ Evolutionary advantage (those without wisdom teeth genes—no impaction problems)

Partial development: ✓ 1-3 wisdom teeth (some developing, others missing—common) ✓ Asymmetric (upper but not lower, or vice versa—wisdom teeth variable)

Full development with adequate space (rare): ✓ 5-10% of population (all four wisdom teeth erupting normally—”lucky” anatomy)

Impacted wisdom teeth (most common): ⚠ 60-70% of population (some/all wisdom teeth impacted—modern norm)

Impacted Wisdom Teeth: Types and Positions

What Are Impacted Wisdom Teeth?

While other people develop impacted wisdom teeth, since they don’t have enough room to erupt into the mouth or grow normally:

Impacted wisdom teeth definition:

⚠ Blocked from erupting (wisdom teeth unable to break through gum—insufficient space) ⚠ Stuck in jawbone (wisdom teeth partially/fully embedded—abnormal position) ⚠ Unable to function (impacted wisdom teeth—cannot be cleaned, used for chewing)

Impacted Wisdom Teeth Positions

An impacted wisdom tooth may:

Position 1: Mesioangular (most common impacted wisdom teeth)

Grow at an angle toward the next tooth:

⚠ Tilted forward (impacted wisdom teeth angled toward second molar—45° typically) ⚠ Pressing against second molar (impacted wisdom teeth pushing—root resorption risk) ⚠ Partially erupted often (impacted wisdom teeth crown visible—root stuck) ⚠ Prevalence: 43% of impacted wisdom teeth (most common type)

Problems with mesioangular impacted wisdom teeth:

• Cavity on second molar (impacted wisdom teeth trapping food—decay developing)
• Bone loss (between teeth—impacted wisdom teeth causing periodontal defect)
• Difficult to clean (gap between teeth—impacted wisdom teeth plaque trap)

Position 2: Distoangular (impacted wisdom teeth angled backward)

At an angle toward the back of the mouth:

⚠ Tilted backward (impacted wisdom teeth angled away from second molar—toward ramus) ⚠ Crown toward throat (impacted wisdom teeth pointing back) ⚠ Often completely embedded (impacted wisdom teeth not visible) ⚠ Prevalence: 6% of impacted wisdom teeth

Position 3: Horizontal (severely impacted wisdom teeth)

Or “lying down” within the jawbone:

⚠ Completely horizontal (impacted wisdom teeth 90° rotated—crown facing second molar root) ⚠ Fully embedded (impacted wisdom teeth entirely in bone—not erupting) ⚠ Pushing directly into second molar (impacted wisdom teeth worst position—high damage risk) ⚠ Prevalence: 3% of impacted wisdom teeth (but most problematic)

Problems with horizontal impacted wisdom teeth:

• Severe second molar root damage (impacted wisdom teeth resorbing root)
• Cyst formation (around impacted wisdom teeth—follicular cyst)
• Difficult extraction (impacted wisdom teeth requiring sectioning, bone removal)

Position 4: Vertical (partially impacted wisdom teeth)

Upright but stuck:

⚠ Correct angle (impacted wisdom teeth vertical—but insufficient space) ⚠ Partially erupted (impacted wisdom teeth crown visible—roots stuck in bone) ⚠ Soft tissue impaction (gum covering partially—impacted wisdom teeth operculum) ⚠ Prevalence: 38% of impacted wisdom teeth

Wisdom Teeth Management: Two Options

The Decision for Wisdom Teeth

There are two ways to deal with impacted wisdom teeth and Dr. Kaufman will discuss them with you when you come for the general exam:

Wisdom teeth management options:

Option 1: Monitoring wisdom teeth (watchful waiting—leaving wisdom teeth in jaw) Option 2: Removing wisdom teeth (extraction—surgically taking wisdom teeth out)

In general impacted wisdom teeth can either, be left in the jaw bone and monitored or they can be removed:

No one-size-fits-all for wisdom teeth:

✓ Individualized assessment (Dr. Kaufman evaluating—your specific wisdom teeth position, age, risks) ✓ Shared decision-making (discussing pros/cons—wisdom teeth choice) ✓ Re-evaluation over time (monitoring decision changeable—wisdom teeth developing problems)

Monitoring Wisdom Teeth: Advantages and Risks

When Wisdom Teeth Can Be Left Alone

There are advantages and disadvantages to each way and I will try to detail here some of them:

Advantages of monitoring wisdom teeth:

✅ Avoiding surgery (no extraction trauma—wisdom teeth staying) ✅ No surgical risks (nerve damage, infection—wisdom teeth monitoring safer acutely) ✅ Preserving teeth (keeping wisdom teeth—may be useful if other molars lost later) ✅ Cost savings (no extraction fee—monitoring wisdom teeth cheaper initially) ✅ No recovery time (no post-op pain, swelling—wisdom teeth undisturbed)

When monitoring wisdom teeth appropriate:

✓ Asymptomatic impacted wisdom teeth (no pain, infection—currently) ✓ Deep impaction (wisdom teeth fully embedded—unlikely to cause problems) ✓ Older patients (50+—wisdom teeth stable for decades, surgery riskier) ✓ Medical contraindications (bleeding disorders, immunosuppression—wisdom teeth extraction dangerous)

Risks of Monitoring Wisdom Teeth

Disadvantages of leaving wisdom teeth:

Risk 1: Cavity and Damage to Adjacent Molar

When monitoring the wisdom teeth we need to check that they do not cause a cavity or damage to the adjacent molar:

Wisdom teeth damaging second molar:

⚠ Cavity formation (impacted wisdom teeth trapping food—second molar decay) ⚠ Root resorption (impacted wisdom teeth pressing—dissolving second molar root) ⚠ Bone loss (periodontal defect—between wisdom teeth and second molar)

Why impacted wisdom teeth cause second molar problems:

• Food trap (gap between wisdom teeth and second molar—impossible to clean)
• Plaque accumulation (bacteria colonizing—wisdom teeth area unreachable by brush/floss)
• Pressure (horizontal wisdom teeth—physically pushing into second molar)

Consequence:

⚠ Losing second molar (trying to save impacted wisdom teeth—losing functional molar instead) ⚠ More extensive treatment (second molar root canal, crown, or extraction—vs. simple wisdom teeth removal)

Risk 2: Gum Disease and Infection from Wisdom Teeth

Sometimes their position can make it difficult to clean and lead to a gum disease or abscess:

Wisdom teeth gum problems:

Pericoronitis (wisdom teeth gum infection):

⚠ Operculum (gum flap over partially erupted wisdom teeth—trapping food, bacteria) ⚠ Inflammation (red, swollen gum—around wisdom teeth) ⚠ Infection (pus under flap—wisdom teeth abscess) ⚠ Recurrent (repeated episodes—chronic wisdom teeth problem)

Symptoms of wisdom teeth pericoronitis:

• Pain (throbbing—at wisdom teeth site)
• Swelling (cheek, jaw—from wisdom teeth infection)
• Bad taste (purulent drainage—wisdom teeth pus)
• Difficulty opening mouth (trismus—wisdom teeth muscle spasm)
• Fever (systemic infection—wisdom teeth spreading)

Periodontal disease from wisdom teeth:

⚠ Bone loss (around wisdom teeth—impossible to clean) ⚠ Deep pockets (7-10mm—between wisdom teeth and second molar) ⚠ Spreading to second molar (wisdom teeth gum disease—affecting adjacent tooth)

Risk 3: Acute Infection Risk from Wisdom Teeth

Due to the fore-mentioned problems, there is always a risk of an acute infection or abscess that will be painful and difficult to treat when wisdom teeth are kept in the jaw:

Wisdom teeth abscess:

⚠ Unpredictable timing (no symptoms for years—then sudden wisdom teeth infection) ⚠ Painful (severe—wisdom teeth abscess throbbing) ⚠ Difficult to treat conservatively (antibiotics temporary—wisdom teeth extraction eventually needed anyway) ⚠ Worse outcomes (extracting infected wisdom teeth—more complications than elective removal)

Wisdom teeth infection complications:

• Facial cellulitis (spreading infection—wisdom teeth causing massive swelling)
• Ludwig’s angina (bilateral neck infection—wisdom teeth life-threatening)
• Mediastinitis (chest infection—wisdom teeth bacteria descending)

Risk 4: Cysts and Tumors from Wisdom Teeth

When teeth develop they are surrounded by supporting tissues who are not required once the tooth is mature. These tissues disappear as the tooth erupts normally into the mouth:

Wisdom teeth follicle and cyst risk:

Dental follicle: ✓ Surrounds developing tooth (normal—protective sac around wisdom teeth) ✓ Disappears with eruption (if wisdom teeth erupt—follicle resorbs)

But since for the impacted wisdom tooth this cannot occur, these tissues linger on:

Impacted wisdom teeth follicle persistence:

⚠ Follicle remains (around unerupted wisdom teeth—tissue not resorbing) ⚠ Cyst potential (follicle fluid accumulating—wisdom teeth cyst forming)

And can give rise to cysts or tumors around the tooth:

Wisdom teeth cysts:

Dentigerous cyst (wisdom teeth follicular cyst):

⚠ Most common (surrounding wisdom teeth crown—fluid-filled sac) ⚠ Enlarging slowly (wisdom teeth cyst expanding—destroying bone) ⚠ Asymptomatic often (no symptoms—wisdom teeth cyst found on X-ray) ⚠ Requires removal (wisdom teeth extraction + cyst enucleation)

Odontogenic keratocyst (from wisdom teeth):

⚠ Aggressive (locally destructive—wisdom teeth area) ⚠ Recurrence rate 25-60% (after removal—wisdom teeth cyst returning) ⚠ Jaw fracture risk (large cyst—weakening bone around wisdom teeth)

Ameloblastoma (wisdom teeth tumor):

⚠ Benign but aggressive (tumor—near wisdom teeth) ⚠ Jaw destruction (extensive—requiring resection) ⚠ Associated with impacted wisdom teeth (follicle undergoing neoplastic change)

Prevalence of wisdom teeth cysts:

• 1-2% of impacted wisdom teeth develop cysts (seemingly low—but serious consequence)
• Risk increases with age (older impacted wisdom teeth—higher cyst rate)

Risk 5: Monitoring Wisdom Teeth with X-Rays

This is one of the reasons that Dr. Kaufman recommends to have a large X-ray every 2 years to see if any changes occur around the tooth:

Wisdom teeth monitoring protocol:

✓ Panoramic X-ray every 2 years (visualizing all wisdom teeth, adjacent teeth, bone) ✓ Checking for:

• Cavity development (on wisdom teeth or second molars)
• Bone loss (periodontal—around wisdom teeth)
• Cyst formation (dark halo—around wisdom teeth)
• Root resorption (second molar—from wisdom teeth pressure)
• Positional changes (wisdom teeth migrating)

Radiation exposure consideration:

• Panoramic X-ray: 0.01 mSv (equivalent to 1-2 days natural background radiation—minimal risk)
• Benefit: Early wisdom teeth problem detection (outweighing small radiation)

Risk 6: Age and Wisdom Teeth Surgery Difficulty

Another consideration when leaving the wisdom teeth, is that older adults may experience difficulty with surgery and more complications after surgery:

Age affecting wisdom teeth extraction:

Younger patients (teens, 20s): ✓ Roots not fully formed (wisdom teeth easier to remove—less bone fusion) ✓ Bone more pliable (faster healing—wisdom teeth extraction recovery quicker) ✓ Fewer complications (nerve damage rare—wisdom teeth nerves not close yet)

Older patients (40s+): ⚠ Roots fully formed (wisdom teeth long, curved—complex extraction) ⚠ Bone denser (more bone removal needed—wisdom teeth extraction difficult) ⚠ Slower healing (weeks longer—wisdom teeth recovery prolonged) ⚠ Higher complication rate (nerve damage 3-5x higher—wisdom teeth nerves intimate) ⚠ Medical comorbidities (diabetes, heart disease—wisdom teeth surgery riskier)

Dr. Kaufman’s consideration:

If monitoring wisdom teeth now (age 20-25), may develop problems later (age 50+) when extraction much harder—preventive removal may be wise.

Wisdom Teeth Removal: Benefits and Risks

Advantages of Removing Wisdom Teeth

On the other hand there are risks involved with the removal of wisdom teeth as well:

Benefits of wisdom teeth extraction:

✅ Preventing future problems (cavity, infection, cyst—wisdom teeth complications avoided) ✅ Protecting second molar (no damage—maintaining functional tooth) ✅ Easier extraction when younger (wisdom teeth surgery simpler—better recovery) ✅ One-time treatment (removing wisdom teeth—problem solved permanently) ✅ Eliminating monitoring (no ongoing X-rays—wisdom teeth gone, no surveillance needed)

When wisdom teeth removal recommended:

✓ Symptomatic impacted wisdom teeth (pain, infection—active problems) ✓ Damage to adjacent teeth (wisdom teeth causing cavity, resorption) ✓ Cyst/tumor (around wisdom teeth—requiring removal) ✓ Orthodontic reasons (crowding—wisdom teeth pushing other teeth) ✓ Preventive (age 16-25) (impacted wisdom teeth likely to cause problems—easier extraction now)

Wisdom Teeth Removal Risks and Complications

Most wisdom tooth extractions don’t result in long-term complications:

Reassuring statistics:

✓ 90-95% uneventful (wisdom teeth extraction—routine recovery) ✓ Serious complications rare (<1%—permanent nerve damage, severe infection)

But some problems that can occur:

Wisdom Teeth Complication 1: Dry Socket

Like a “dry socket,” a complication that delays healing and causes pain:

Dry socket (alveolar osteitis) after wisdom teeth removal:

⚠ Blood clot dislodges (wisdom teeth socket—exposing bone) ⚠ Bone exposed to oral environment (wisdom teeth extraction site—extremely painful) ⚠ Delayed healing (weeks longer—wisdom teeth socket not filling)

Dry socket symptoms:

• Severe pain (3-4 days post-wisdom teeth extraction—throbbing, radiating to ear)
• Bad taste/odor (necrotic debris—in wisdom teeth socket)
• Visible bone (white bone—in wisdom teeth extraction site)

Dry socket incidence:

• Overall wisdom teeth extractions: 2-5%
• Lower impacted wisdom teeth: 20-30% (much higher—mandible more prone)
• Risk factors: Smoking, oral contraceptives, poor oral hygiene—after wisdom teeth removal

Treatment for dry socket:

✓ Medicated dressing (eugenol paste—in wisdom teeth socket, pain relief) ✓ Gentle irrigation (saline—cleaning wisdom teeth socket) ✓ Pain medication (NSAIDs, opioids—managing wisdom teeth dry socket pain) ✓ Healing: 1-2 weeks (eventually—wisdom teeth socket filling)

Wisdom Teeth Complication 2: Infection

An infection in the socket from bacteria or trapped food particles:

Wisdom teeth extraction site infection:

⚠ Bacterial contamination (wisdom teeth socket—despite sterile technique) ⚠ Food impaction (debris in wisdom teeth socket—infection source) ⚠ Abscess formation (pus—in wisdom teeth extraction site)

Infection symptoms:

• Increasing pain (worsening after wisdom teeth removal—not improving)
• Swelling (cheek, jaw—after wisdom teeth extraction)
• Pus drainage (foul taste—from wisdom teeth socket)
• Fever (systemic—wisdom teeth infection spreading)

Wisdom teeth infection incidence: 1-5% of extractions

Treatment:

✓ Antibiotics (amoxicillin, clindamycin—treating wisdom teeth infection) ✓ Irrigation (cleaning wisdom teeth socket) ✓ Possible drainage (if abscess—wisdom teeth pus removal)
