How to Protect Your Enamel Against Acids in Your Diet

The good news is that it’s possible to both reduce your ongoing risk of tooth enamel loss and actively strengthen acid-weakened enamel.

1. Cut Back on Acidic Foods and Drinks

The acids in food and beverages like sour candy, sodas, sports drinks and fruit juices, can wear away your enamel over time. This is called ‘tooth erosion’.iv

2. Try Water or Dairy After an Acidic Meal or Drink

While it’s best to avoid acidic treats, if you do indulge occasionally, try rinsing your mouth with water or enjoying a dairy-based snack – like a cube of cheese – afterwards. The calcium in dairy products helps neutralize acids that attack your enamel.iv

3. Don’t Brush Your Teeth Immediately After Meals

Tempting as it may be to brush your teeth straight after a meal, the optimum time to brush is about one hour after eating. This will allow your saliva some time to naturally wash away acids and help to reharden your enamel.iv

4. Drink Acidic Drinks Through a Straw to Avoid Contact With Your Teeth

Drinking through a straw helps push the liquid to the back of your mouth and away from your teeth. Don’t swish acidic drinks around, or keep them in, your mouth.iv

5. Better Still, Drink Water

Drinking water helps rinse away dietary acids and is especially important if you have low saliva volume. Saliva is the mouth’s natural defense against acid, helping to neutralize acidity and remineralize tooth enamel. If you aren’t producing enough, your risk of tooth enamel loss

6. Chew Sugar-Free Gum After Eating

Chewing gum boosts saliva production, which can help to neutralise acids from sugary food and drinks. Always look for gum with the American Dental Association Seal of Acceptance.iv

7. Brush Twice a Day with a Soft Toothbrush

One of the easiest ways you can protect your enamel is with a good oral care routine. Brush your teeth with a soft-bristled toothbrush, brushing gently twice a day for at least two minutes.v
