When to brush your teeth
When and how often should you brush your teeth?
from Alan Carr, D.M.D.
The American Dental Association recommends brushing your teeth at least twice a day.
When you brush your teeth, you help remove food and plaque — a sticky film that forms on your teeth and contains bacteria. After you eat a meal or snack that contains sugar, the bacteria can release acids that attack tooth enamel. Repeated attacks can break down tooth enamel and lead to cavities. Plaque that isn't removed also can harden into tartar, making it harder to keep teeth clean.
In choosing when to brush your teeth, you might also consider your diet. If you've eaten an acidic food or drink, avoid brushing your teeth for at least 30 minutes. These acids weaken tooth enamel, and brushing too soon can remove enamel. If you know you're going to eat or drink something acidic, brush your teeth beforehand.
In addition to brushing your teeth, the American Dental Association recommends that you:
- Floss daily
- Eat a healthy diet and limit between-meal snacks
- Replace your toothbrush every three to four months, or sooner if the bristles are frayed
- Schedule regular dental checkups
