It is a procedure predominantly applied when molars first erupt, at the age of 6, and again at the age of 12 years old.
Sealants prevent food from getting trapped in these grooves, hence not allowing bacteria from growing in them.
Dental sealant is a clear or white resin material that bonds with these grooves and depressions on your teeth and seals them to provide protection and to make it much easier to clean by brushing.
After sealing, bacteria cannot reach the pits and grooves and cause decay. Applying sealants requires no drilling or removal of the tooth surface.
Sealants generally last from 3 to 5 years. A dental sealant only provides protection when it is fully intact, checking for their integrity is another reason to have regular Dental Check-Ups.
