Definition: Caries is the clinical name for cavities or tooth decay. Decay occurs when plague, the sticky substance that forms on teeth, combines with the sugars and / or starches of the food we eat. This combination produces acids that attack tooth enamel. The best way to prevent tooth decay is by brushing twice a day and flossing daily. Eating healthy foods and avoiding snacks and drinks that are high in sugar are also ways to prevent decay.
