A sealant is a thin, plastic coating applied to the chewing surface of molars, premolars and any deep grooves (called pits and fissures) of teeth. Teeth with these conditions are hard to clean and are very susceptible to decay. A sealant protects the tooth by sealing deep grooves, creating a smooth, easy to clean surface.
A sealant can protect teeth from decay for many years, but need to be checked for wear and chipping at regular dental visits.
How are sealants applied?
First, the teeth are cleaned and dried to prepare them to accept the sealant. The sealant is then placed onto the tooth enamel, where it bonds directly to the tooth and hardens.
