Sealants are a protective barrier bonded to the chewing surface of a tooth. It prevents bacteria from accumulating into tiny grooves on the surfaces of the teeth. This does not eliminate the need for proper dental care, but is recognized as an effective and valuable asset in the prevention of tooth decay. The application of sealants does not require anesthetic or drilling of the tooth. Talk to Dr. Spero or your hygienist to find out how sealants can benefit you or your child.
