A sealant is a thin, plastic coating applied to deep grooves (called pits and fissures) of the chewing surface of teeth.  More than 75% of dental decay begins in these deep grooves.  A sealant protects the tooth by sealing the grooves, creating a smooth, easy to clean surface.  Sealants can protect teeth from decay for many years, but need to be checked for wear and chipping at regular dental visits. The process only takes a few minutes per tooth.

Proper home care, a balanced diet, and regular dental visits will aid in the life of your new sealants.
