Sealants are used to help protect the teeth from decay. The dental sealant is a thin coating usually applied to the fissures (grooves) of the back teeth. Even though plaque and food particles can be removed from the smooth surfaces of the teeth by brushing and flossing, it can be difficult to get all the food particles out of the depressions and grooves of the tooth. The sealant forms a protective shield over the enamel of the tooth by bonding into the depressions and grooves of the tooth, adding an extra protection for the tooth.
