Sealant Fact Sheet

One of the most recent advances in preventive dentistry has been the development of sealants. These materials protect the pits and grooves in the back teeth from the bacteria that may cause decay. Cavities on the chewing surfaces of the back teeth make up almost 50% of the decay in children’s teeth. By applying sealants to these surfaces the incidence of tooth decay can be prevented or reduced.

What is a sealant?

A sealant is clear or white plastic coating applied to the chewing surfaces of the back teeth.

Why are sealants applied?

Sealants protect teeth from decay. The pits and grooves in the back teeth are difficult to keep clean because the bristles of the toothbrush cannot reach into them. Therefore, these pits and grooves are places that food and bacteria hide.

How is a sealant applied?

The application of a sealant is a quick and painless procedure. The chewing surfaces are first cleaned, etched to improve adhesion, washed and dried. The sealant material is then appli ed to the tooth surface and allowed to harden. A special light is used to help it harden.

Who should have sealants applied?

Children with newly erupted permanent molars or premolars are excellent candidates for sealants. Sealants can only be applied to cavity free surfaces. Therefore it is important to have sealants applied to the teeth as soon as possible.

Sealant protection is intended to be used as part of a total preventive program. Regular dental visits, the use of fluoride, daily brushing, flossing, and also limiting sweet sugary snacks are essential in preventing dental disease.
