There are certain foods and beverages that are bad for your teeth and can increase your risk of decay, enamel erosion, and other dental problems.
Foods to Avoid
- Citrus fruits (such as oranges, lemons, and grapefruits) are highly acidic. Frequent exposure to this acid can erode tooth enamel over time, making teeth more sensitive and vulnerable to decay.
- Sour candies are a double threat: they are both sugary and acidic. The sugar feeds harmful bacteria in your mouth, while the acid softens and wears away enamel.
- Dried fruit (like raisins, apricots, and dates) tends to be sticky and clings to teeth. This allows sugar to sit on the tooth surface for longer periods, increasing the risk of cavities.
- Crisps and other starchy snacks break down into simple sugars and can get trapped between teeth and in the grooves of molars, feeding cavity-causing bacteria.
- Bread and refined carbohydrates quickly convert to sugar in the mouth and can become gummy, sticking to teeth and contributing to plaque buildup.
Drinks to Limit or Avoid
- Fizzy (carbonated) drinks, including regular and diet soft drinks, are acidic and can coat your teeth in acid with every sip. This acid weakens enamel and, over time, can lead to erosion and sensitivity.
- If you do drink fizzy drinks, it is better to rinse your mouth with water afterwards rather than brushing immediately. Brushing right away can scrub softened enamel and cause more damage.
- Alcoholic drinks can dry out your mouth. A dry mouth has less saliva, and saliva is essential for protecting your teeth because it helps wash away plaque, food particles, and neutralise acids.
How to Protect Your Teeth
- Drink plenty of water, especially after consuming acidic or sugary foods and drinks.
- Limit how often you snack on sugary or starchy foods throughout the day.
- Wait at least 30 minutes after acidic foods or drinks before brushing your teeth.
- Maintain a strong oral hygiene routine: brush twice a day with fluoride toothpaste and floss daily.
- Visit your dentist regularly for check-ups and professional cleanings.
By being mindful of what you eat and drink, and by taking simple protective steps, you can help keep your teeth strong, healthy, and free from unnecessary damage.
