The deep grooves in molars and premolars are hard to reach and clean with toothbrush bristles. A sealant is tooth-colored resin material that is placed in the grooves that act as a barrier to keep out bacteria, plaque and food. Dr. Wright or our hygienist can place sealants. If properly placed, a sealant can protect your tooth from decay on the chewing surfaces of your teeth. Further, it can withstand normal chewing force but typically doesn’t last forever. Thus, sealants are checked for integrity at regular checkups and can be replaced if they’re breaking down. They’re most commonly placed on children but also on adults as a conservative preventative restoration.
