Dental sealants are protective coatings applied to the chewing surfaces of the back teeth, especially the molars and premolars. These teeth often have deep grooves and pits where food particles and bacteria can easily collect. Because these areas are difficult to clean with a toothbrush, they are more vulnerable to cavities. Sealants create a protective barrier that helps prevent plaque and bacteria from settling into these grooves.

The application of dental sealants is simple, quick, and painless. First, the dentist cleans and dries the tooth surface to prepare it for the sealant. A special conditioning solution is then applied to help the sealant bond securely to the enamel. The liquid sealant material is carefully painted onto the chewing surface of the tooth, where it flows into the small grooves and pits. A curing light may be used to harden the sealant and keep it firmly in place.
