Sealants are a safe and painless way of protecting your teeth from decay. A sealant is a protective plastic coating, which is applied to the biting surfaces of the back teeth. The sealant forms a hard shield that keeps food and bacteria from getting into the tiny grooves in the teeth and causing decay.
Sealants are only applied to the back teeth – the molars and premolars. These are the teeth that have ‘pits’ (small hollows) and ‘fissures’ (grooves) on their biting surfaces.
