1 After you eat, tiny bits of food are left between your teeth. Bacteria grow on them, forming plaque.  The bacteria digest the carbohydrates (sugars and starches) in food and produce an acid. This acid dissolves the enamel (the hard outer layer of your tooth) and a hole (cavity) is formed.
Fluoride, a naturally-occurring mineral, helps prevent cavities in children and adults by making the outer surface of your teeth (enamel) more resistant to the acid attacks that cause tooth decay.efore teeth break through the gums, the fluoride taken in from foods, beverages and dietary supplements makes tooth enamel (the hard surface of the tooth) stronger, making it easier to resist tooth decay.
