Dental sealants are a useful tool in preventing the formation of cavities that stems from the buildup of plaque on teeth. They are largely a preventative measure that acts as a barrier that coats your teeth. Dental sealants are painted on your teeth until the grooves are covered completely and then hardened using a special light. The sealant itself is a thin coating of tooth-colored or clear material that provides protection from harmful bacteria. This procedure is simple and relatively quick, so you can have a protected smile in no time at all. Dental sealants help protect your teeth from decay for several months after application. It’s important to maintain your current oral healthcare routine while in sealants so that your smile remains healthy.
