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.
Surveys show the majority of all cavities occur in the narrow pits and grooves of a child's newly erupted teeth because food particles and bacteria are not easily cleaned out. A risk assessment by a dentist best determines if a child is a candidate for dental sealants. Dental sealants act as a barrier to seal-off space between the tooth surface and any small food particles or bacteria that may otherwise cause a cavity in an unsealed tooth.
