Dental Sealants are a protective coating applied to molars and premolars to seal the occlusal surfaces and prevent tooth decay. Sealants form a protective shield on the tooth, sealing up grooves that are not easily cleaned, and prevent cavities. Sealants can last up to ten years but do wear off over time. So, regular checkups are still required and sealants may be reapplied over time.
The best candidates for sealants are children and teens because teeth are especially vulnerable to cavities between ages six and fourteen. However, an adult with no tooth decay will also benefit from dental sealants. Since these sealants are clear in color, they can even be applied over some fillings.
