Sealants are a safe and painless way or 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.
Which teeth should be sealed?
Sealants are only applied to the back teeth – the molars and premolars. These are the teeth that have pits and fissures on their biting surfaces. Your dentist will tell you which teeth should be sealed after they have examined them, and checked whether the fissures are deep enough for sealing to help. Some teeth naturally form with deep grooves which will need to be sealed, others with shallow ones which will not need sealing.
