Sugary Drinks and Your Oral Health

Sugary drinks include sweetened beverages such as regular soft drinks, energy drinks, sports drinks, fruit juices, cordial, sweetened teas, rice drinks, sugar cane and bean beverages. While these drinks may seem harmless, they contain high levels of sugar and acid that can harm both your dental and general health.

Excessive consumption of sugary or acidic drinks can lead to weight gain, obesity, and poor nutrition in adults and children. In younger children, sugary drink intake often reduces milk consumption, resulting in lower calcium levels and increasing the risk of osteoporosis and bone fractures later in life. These drinks also contribute significantly to tooth decay and dental erosion.

The Hidden Dangers of Sugary Drinks

  • A 600ml bottle of soft drink contains around 16 teaspoons of sugar.

  • A 600ml sports drink has about 9 teaspoons of sugar.

  • Nearly 47% of children aged 2–6 consume sugary drinks daily.

  • Just 340ml of sugary drink per day can increase your risk of type 2 diabetes by 22%.

Oral Health Effects

Frequent consumption of sugary drinks accelerates tooth decay and enamel erosion. Even diet soft drinks, although sugar-free, are highly acidic and can cause similar damage. Many sugary beverages also contain caffeine, which can affect hydration and lower the mouth’s pH, reducing saliva’s natural ability to protect your teeth.

Early exposure is particularly harmful. Prolonged or repeated contact between a baby’s teeth and sugary liquids has been linked to early childhood caries.

Smart Tips to Cut Back on Sugary Drinks

  • Choose water first when you’re thirsty.

  • Carry a water bottle to avoid buying sweet drinks.

  • When ordering meals, opt for water or milk instead of soft drinks.

  • Check nutrition labels carefully—“healthy-sounding” drinks can be misleading.

  • For alcoholic beverages, explore lower-sugar options.

  • Avoid the soft drink aisles and checkout specials when shopping.

  • Limit how often and how much you drink sugary drinks per day.

  • Use a straw to reduce acid contact with teeth.

  • Rinse or brush your teeth after drinking sugary beverages.

  • Encourage children to carry a water bottle to school.

  • Avoid flavored milk or fruit juices with added sugar.

  • If vending machines at school offer sweet drinks, advocate for healthier alternatives.

Sugary Drinks and Infant Care

For babies with teeth:

  • Never settle your baby to sleep with bottles containing milk, cordial, fruit juice, or soft drink.

  • If your child needs comfort before sleep, offer water or a dummy instead.

Establishing healthy habits early helps protect both your child’s dental health and their long-term wellbeing.

 

Dental erosion in Glen Iris – Are you washing away your teeth?

  • Dental Erosion and Acidic Drinks

    When acids come into contact with your teeth, the enamel and dentine can gradually soften and dissolve. This process is known as dental erosion. Over time, dental erosion can lead to tooth wear, increased sensitivity, and even tooth loss if left untreated.

    Causes of Dental Erosion

    Many common drinks are acidic and can damage teeth when consumed frequently. Acidic drinks weaken the protective enamel layer, making your teeth more prone to decay, sensitivity, and discoloration. The acidity of a drink is measured by its pH level — the lower the pH, the higher the acid content and the greater the risk to your teeth.

    Early Signs of Dental Erosion

    Look for the following warning signs:

    • Teeth appearing more yellow as enamel thins and dentine becomes visible

    • A smooth or glazed look on tooth surfaces

    • Sensitivity to temperature or sweetness

    • Transparent or thinning edges of the front teeth

    If you notice these changes, schedule an appointment with your dentist. Early detection and treatment can slow down or prevent further damage.

    Acidic Drinks and Their pH Levels

    The table below shows examples of popular drinks and their acidity levels. Drinks with a pH between 1 and 5 are highly acidic and can cause dental erosion if consumed often.

    pH Example Drink Acid Content (Source: Choice, July 2010)
    1 Stomach acid
    2 Lemon juice 2.45 Pepsi, 2.53 Coca-Cola, 2.80 Cottee’s Lemon Crush, 2.85 Cottee’s Diet Cordial No Added Sugar, 2.85 Pepsi Max, 2.9 Sunnyboy Glug Cola

    4 Tomato juice 4.04 Berri Low Acid Orange Juice
    5 Rainwater
    6 Milk 6.70 Sanitarium Up and Go Banana & Honey
    7 Pure water Neutral pH

    How to Prevent Dental Erosion

    Protect your teeth from acid wear with these practical tips:

    • Limit consumption of soft drinks, fruit juices, and sports drinks

    • Rinse with water after having acidic beverages

    • Wait at least 30–60 minutes before brushing your teeth after consuming acidic foods or drinks

    • Use fluoride toothpaste to strengthen enamel

    • Chew sugar-free gum to increase saliva flow and neutralise acids

    • Visit your dentist for regular dental check-ups and professional fluoride treatments

    When to See Dr. Kaufman

    If you regularly consume any of the acidic drinks listed above or notice signs of enamel wear, visit Dr. Kaufman for a professional assessment. After a thorough examinaion, Dr. Kaufman can provide tailored advice, preventive care, and protective treatments to help manage dental erosion.

Dental Erosion- Acidic drinks and food in Glen Iris

Dental Erosion: Causes, Symptoms, and Prevention

Dental erosion, also known as erosive tooth wear, occurs when acid dissolves the surface of the tooth. This leads to thinning of the enamel, which weakens the tooth and causes sensitivity. When the enamel layer wears away, the softer dentine beneath becomes exposed and dissolves even faster in acid. Preventing dental erosion is key to maintaining strong, healthy teeth.

Where Does the Acid Come From?

The acid that causes dental erosion usually comes from the food and drinks we consume. Common sources of dietary acids include:

  • Soft drinks

  • Energy drinks and sports drinks

  • Vinegar and pickled foods

  • Citrus fruits and fruit juices

  • Fruit-flavoured teas (e.g. lemon, peach, rosehip)

  • Cordial and alcoholic drinks

  • Sour lollies and chewy sweets

  • Chewable Vitamin C tablets and effervescent medications

Even sugar-free drinks can be damaging if they are high in acid. Common acidic ingredients to look out for include:

  • Citric acid (food acidity regulator 330)

  • Sodium citrate (regulator 331)

  • Malic acid (preservative 296)

  • Ascorbic acid (vitamin C additive 300)

  • Fruit juice concentrate

Acid from the stomach can also cause dental erosion, especially in people with vomiting, reflux, or conditions such as gastroesophageal reflux disease (GERD), bulimia, anorexia, or pregnancy-related morning sickness.

What Else Increases the Risk of Dental Erosion?

Low saliva flow, or dry mouth, increases susceptibility to acid damage. Saliva helps wash away and neutralise acids in the mouth. Conditions and habits that can reduce saliva include:

  • Certain medications or multiple medicines taken together

  • Head and neck radiotherapy

  • Stress and anxiety

  • Autoimmune conditions like Sjögren’s syndrome

  • Smoking

  • Diabetes

How to Prevent Dental Erosion

You can protect your teeth from acid damage with a few simple habits:

  • Limit acidic foods and drinks, especially between meals

  • Only have acidic beverages at meal times when saliva levels are higher

  • Avoid holding acidic drinks in your mouth; swallow them quickly

  • Eat low-acid fruits such as bananas, melons, pears, and papayas instead of fruit juices

  • Chill acidic drinks, as warmer liquids cause more erosion

  • After acidic foods, vomiting, or reflux, rinse your mouth with water, milk, or a fluoride mouth rinse

  • Visit your Dr. Daniel Kaufman to check for underlying medical conditions that may increase acid exposure

Brushing and Dental Care Tips

Good oral hygiene remains vital. Traditionally, people were advised to wait 30–60 minutes before brushing after acid exposure, but new research shows this delay may not help enamel repair. Instead, focus on consistent, gentle daily care:

  • Brush twice a day using fluoride toothpaste

  • Use a soft toothbrush and gentle circular motions

  • Rinse your mouth with water, milk, or fluoride mouthwash after acid exposure

  • Consider a toothpaste with stannous fluoride (SnF₂), as it provides greater resistance against acid wear

Sugary Drinks and Your Health: Choose Water Instead

Tap water is the best and most affordable way to stay hydrated while protecting your teeth. Choosing water instead of sugary or acidic drinks helps prevent dental erosion, cavities, and other chronic health issues.

The Risks of Sugary Drinks

  • One 600 ml bottle of soft drink can contain up to 16 teaspoons of sugar

  • Drinking one can of soft drink a day can add up to 6.5 kilograms of weight gain in a year

  • Sugar and acid together increase the risk of tooth decay and erosion

  • Overconsumption of sugary drinks raises the risk of heart disease, kidney disease, type 2 diabetes, stroke, and some cancers

Tips to Drink More Water and Fewer Sugary Drinks

  • Ask for tap or sparkling water when dining out

  • Carry a reusable water bottle

  • Keep a glass of water nearby throughout the day

  • Choose tap water during and after exercise instead of sports drinks

  • Drink plain milk, or tea and coffee without added sugar

  • Save money from skipping sugary drinks to enjoy other activities

The World Health Organization recommends consuming no more than seven teaspoons (27.5 g) of added sugar per day—equivalent to 5% of your total energy intake—to reduce the risk of tooth decay, obesity, and chronic diseases.
