A sealant is a thin, plastic coating applied to the chewing surface of molars, premolars (back teeth) and any deep grooves (called pits and fissures) of teeth. More than 90% of dental decay begins in these deep grooves. 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.
Sealants actually were developed about 50 years ago, but didn't become commonly used until the 1970s. Today, sealants are very popular and effective; young children are great candidates for preventative measures like sealants because in many cases, decay has not set in.
Sealants can protect teeth from decay on the average 3 to 7 years, but need to be checked for wear and chipping at regular dental visits. Eating tacky/sticky foods can break the integrity of the sealants and can require frequent applications. We will assess for these conditions at regular check-up visits.
