Sealants are a very effective preventive therapy against tooth decay. On the chewing surface of the baby and adult molars are pits and fissures, which are normal imperfections of these teeth. Sealants fill in these areas to protect them from decay.
The sealant is a liquid that becomes hard like plastic after it is applied to the tooth. Sealant therapy, which was introduced over twenty years ago, is non-invasive (no drilling) and doesn’t require a local anaesthetic.
