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 easily accumulate. Because these areas are difficult to clean with a toothbrush, they are more vulnerable to cavities. Sealants create a smooth protective barrier that helps prevent plaque and bacteria from settling in these grooves.

The application of dental sealants is simple, quick, and painless. First, the dentist thoroughly cleans and dries the tooth surface. A special conditioning solution is applied to help the sealant bond securely to the enamel. The liquid sealant is then 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.
