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.
