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.
Bacteria can build up in the grooves and cause cavities. Dental sealants can help: Keep food, acids, and plaque from sitting in the grooves of the molars and premolars; Prevent decay and cavities; Save time, money, and the discomfort of getting a filling; Children are most at risk for cavities on molars. Sealants can help protect permanent molars. Permanent molars come in when children are about 6 years old and then again when they are 12 years old. Getting sealants soon after the molars have come in will help protect them from cavities. Adults who do not have cavities or decay on their molars can also get sealants.
