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.
Most individuals have existing pits and grooves in their teeth.
Adults can benefit from sealants. The dentist or dental hygienist will isolate the tooth or teeth to be treated. An etching gel is applied to the tooth and rinsed after 15 seconds. The site is dried and the sealant material is applied and hardened by a special curing light.
