Fissures are grooves that naturally occur on the biting surfaces of teeth. When the fissures are deep and narrow the bristles of the toothbrush cannot fit and clean out the food particles. When food is trapped bacteria can multiply within these deep and narrow grooves and make a sticky coating called plaque which can then cause tooth decay. Not all fissures are prone to decay the deep narrowest fissures are at risk.
A fissure sealant is a protective coating placed over the fissures to protect the teeth from plaque and decay. Fissure sealants are painless and non-invasive with a coat of the sealant applied to a cleaned tooth which then sets forming a barrier that stops food, bacteria and plaque acids from contacting the tooth.
