What you eat and how often you eat can easily affect your development of tooth decay. Our teeth are covered with a sticky firm of bacteria called plaque. If your don’t clean your teeth after eating , plaque converts sugar and foods into acids that can attack your tooth enamel. It cannot be removed by our regular brushing and flossing, to prevent cavities and maintain good oral health, your diet — what you eat and how often you eat are important factors. Changes in your mouth start the minute you eat certain foods. Bacteria in the mouth convert sugars and carbohydrates from the foods you eat to acids, and it’s the acids that begin to attack the enamel on teeth, starting the decay process. The more often you eat and snack, the more frequently you are exposing your teeth to the cycle of decay.
