What are sealants?
Sealants are a thin plastic coating painted on chewing surfaces of molars and premolars. They act as a barrier, protecting your teeth against decay-causing bacteria. The sealant bonds to the grooves in your teeth forming a protective shield over the enamel of each tooth. Sealants have proven effective at preventing cavities in adults as well as children, but are most commonly used on children. Ask your dentist whether sealants are a good choice for your family.
