The pits and fissures of your teeth are prime areas for opportunistic, decay-producing bacteria. Even regular brushing sometimes misses some of these intricate structures on the chewing surfaces of your teeth.
A sealant is a thin coating applied to the chewing surfaces designed to prevent the intrusion of bacteria and other debris.
Sealants actually were developed about 50 years ago, but didn’t become commonly used until the 1970s. Today, sealants are widely popular and effective.
Sealants are applied by first cleaning the tooth surface, followed by “etching” the tooth with an abrasive substance, for better retention, and then applying the sealant material. Our office uses both a light-cured and a self-cure sealant material. Sealants usually need re-application every five to ten years.
