Some foods may have protective qualities. Cocoa and rice contain a substance that protects against tooth decay. A very small portion of aged cheese or raw peanuts, eaten before or after a snack or meal, helps to neutralize mouth acids and to remineralize teeth. Fibrous foods, such as fruits and vegetables, also help to prevent tooth decay. They stimulate salivation, a natural mouth rinse.
Milk is a good snack and a good mealtime drink.
Drink it with sweet foods to help wash sugar from your mouth. Chewing sugarless gum after meals promotes production of saliva and helps neutralize tooth-decaying acids in plaque. It is good to brush your teeth after eating, but if you can't, chewing sugarless gum is an alternative.
