A sealant is a clear or white material that is applied to the chewing surfaces of the back permanent teeth. It acts as a shield to protect the chewing surfaces from cavities. The chewing surfaces of the back teeth have very deep pits and grooves where sugary foods, etc. can adhere. These grooves are so narrow that a single tooth brush bristle can NOT reach inside to clean them. Only sealants can prevent decay in these areas.

Sealants are applied to permanent molars once they have erupted. Ideally it is best to apply the sealant as soon as possible after the tooth has erupted. We can tell you when it is the best time to apply them. Newly erupted teeth are more vulnerable to decay because they have not had the benefits of topical application of fluoride. Many unsealed molars can develop occlusal decay within 1-2 years.

How are sealants applied?

First, the tooth is cleaned.

Secondly, the tooth is isolated and the chewing surface is roughened with an acidic gel to help the sealant adhere to the tooth.

Third, the sealant is applied to the chewing surface of the tooth, and then hardened with a bright light for 20 seconds.

The tooth is now protected with the sealant.

Without proper hygiene or regular dental visits, teeth that are sealed can still get decay. Proper flossing is required, as sealants do not protect the "in between" areas of the teeth.
