Fissure Sealants

Your back teeth (Molars & Pre-molars) have pits and grooves on the biting surface, some of which can be deep and difficult to clean with normal brushing. Food/Debris can get trapped/wedged in them, and this creates a suitable breeding place for plaque bacteria, which will generate cavities. The fissure sealant fills those grooves and also releases fluoride into the groove walls, making it resistant to acidic attacks from the bacteria. Also, it makes the deep grooves shallower, enabling better cleaning and thereby no cavities!
