Dental sealants are a thin, protective coating applied to the chewing surfaces of molars and premolars to prevent tooth decay. They are typically made of a plastic material and are designed to seal out bacteria and food particles that can cause cavities.
Sealants are an important preventive measure for children and adolescents, as they are more likely to develop cavities in their back teeth. Sealants can also be beneficial for adults who have a history of cavities or who are at high risk for developing them.
