A dental sealant is a thin plastic coating painted on the chewing surfaces of teeth. Numerous studies have shown them to be highly effective in the prevention of decay.
Sealants are extremely effective when properly applied.
They act as a physical barrier to decay and protection is determined by the sealant's ability to adhere to the tooth. In fact, studies have shown that sealants actually stop the decay process when placed on top of a slightly decayed tooth. Sealants should last about five years although some may last for up to ten years. Sealants should not be considered as permanent and regular dental checkups are necessary. Sealants are overcoming the age barrier.
