Fissure sealants are a thin protective coating applied mainly to the chewing surfaces of teeth. It is applied mainly to the molars where there are deep fissures, pits or grooves which harbor bacteria causing decay as they multiply. These are typical areas that are inaccessible to the toothbrush, which in turn promotes decay. The First permanent molars erupt around the age of six and need to be protected especially if they have deep grooves as they stay for life. The remaining permanent teeth have varying ages of eruption which need to be monitored for deep fissures as they erupt.
This is a painless procedure, once the tooth surface is cleaned; the flowable fissure sealant material is applied along the grooves of the tooth and waits for it to harden thus protecting the tooth from formation of decay or caries. They are then monitored during the child's regular checkups and may have to be reapplied if they have worn away.
