Many permanent teeth erupt into the mouth with deep pits and grooves on the chewing surface. These deep fissures are difficult or impossible to keep clean with a tooth brush, and they become a natural place for tooth decay to strike a newly erupted tooth. We have found dental sealants to be a safe, painless and low-cost way to help protect teeth from decay. A sealant is a thin, plastic, translucent coating bonded to the chewing surfaces of the molars and premolar teeth. This fills in the deep grooves of the teeth and acts as a shield to keep food and bacteria from getting into the tooth.
