How does your diet impact your oral health?

Diet and Your Dental Health: Smart Choices for Healthy Teeth and Gums

Everything you eat and drink affects your teeth and gums—especially when it comes to the risk of tooth decay. Tooth decay is driven by bacteria that feed on sugars in your food and drinks, producing acids that attack the outer enamel layer.

To keep your diet from harming your dental health, here are key points to remember:

Drink Plenty of Water
Water is calorie-free, stress-free, and very affordable! In most Australian areas, tap water includes fluoride—one of the easiest and most effective ways to help prevent tooth decay. Bottled water typically lacks fluoride due to filtration. Regularly sipping water throughout the day is a simple step for better oral health.

Limit Snacking Between Meals
Saliva is vital for neutralising acid attacks and helping teeth recover after eating. Frequent snacking means your teeth get less rest from those attacks, increasing your risk for decay. Keep sugary treats to mealtimes rather than snacking between meals.

Be Mindful of Hidden Sugars
It’s not only obvious sweets like lollies or sodas that cause decay—other snack foods such as biscuits, crackers, cereals, chips, and dried fruit also contain sugars that can initiate acid attacks on enamel.

Consider Sugar-Free Gum
Chewing sugar-free gum (never gum with sugar) after meals boosts saliva production. A 20-minute chew after eating can help neutralise harmful acids and support enamel health.

Oral Health & Eating Disorders: Glen Iris Dental Advice from Tooronga Family Dentistry

Our dietary habits—from excess sugar to too little fruit or vegetables—have a major impact on oral health. Harmful eating disorders and nutritional deficiencies can cause lingering or even permanent dental damage.

Oral Health Consequences of Eating Disorders

  • Vitamin Deficiencies:
    Lack of essential vitamins causes easy or unexplained gum bleeding and inflamed mouth lining.

  • Dry Mouth & Cracked Lips:
    Poor nutrition leads to low saliva, chronic dryness, and cracked lips.

  • Mineral Shortages:
    Calcium deficiency increases tooth decay and gum disease; iron deficiency leads to mouth sores; vitamin B3 deficiency can result in bad breath and ulcers.

  • Frequent Vomiting:
    Teeth exposed to stomach acid lose enamel, become brittle, sensitive, and discoloured. Advanced erosion can expose pulp, causing infection or tooth death.

  • Mouth Ulcers & Injury:
    Sharp enamel edges from acid erosion trigger ulcers and mouth lining sores. Purging can cause redness, cuts, especially on the mouth’s roof, and binge-purge cycles may enlarge and inflame salivary glands.
