Dental sealants are an excellent way to prevent cavities. A dental sealant is usually recommended on permanent molars when they first erupt in children. A sealant is tooth colored and it is bonded into the groovy biting surfaces of your teeth. Many times these areas are spots where cavities start in children as the grooves can be so deep that bristles of the toothbrush do not even fit into them. We may be able to prevent cavities by placing these sealants in children, and we even recommend them in some high risk adult patients.
