Dental sealants are protective coatings applied to the chewing surfaces of the back teeth, particularly the molars and premolars. These teeth often contain deep grooves and pits where food particles and bacteria can accumulate easily. Because these areas are difficult to clean with a toothbrush, they are more prone to cavities. Sealants help protect these surfaces by creating a smooth barrier that prevents plaque and bacteria from settling in the grooves.

The application of dental sealants is a simple and painless procedure. First, the dentist thoroughly 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 tiny pits and fissures. A curing light may be used to harden the sealant and secure it in place.
