Sealants are a tough, plastic material designed to stick to the enamel of the tooth in the grooves where food collects. The tooth is prepared with a special cleanser that is quickly applied then rinsed with water. The sealant material is brushed onto the surface of the tooth and dried with a special curing light to make it hard. The process is very similar to applying nail polish to a fingernail.

During this procedure, the teeth do not need to be numb. Sealants reduce the risk of cavities forming in these grooves, which can be difficult to keep clean. These sealants do not last forever and will need to be replaced as they wear away from the tooth surface. Not all teeth are good candidates for sealants and the doctors will determine which teeth could receive the most benefit from the application.
