Dental sealants are thin plastic coatings painted on the chewing exteriors of the molars and premolars to protect the tooth from harmful bacteria and decay. This procedure is designed to be an aid in deterring cavities, particularly in children. The teeth are given a coating, which is a painless procedure done without anesthetic. While frequent brushing and daily flossing can get rid of food deposits and plaque from the tooth’s surfaces and canals, the bristles cannot fully reach into all the corners and crevices of your gums and teeth. As such, the sealants rapidly bond into the indentations, canals, and grooves of the tooth, thus forming an effective shield over the enamel of the tooth and inhibiting plaque build-up.
