Dental sealants are thin plastic coatings which are applied to the chewing surface of the molars--where most tooth decay occurs in children and teens. Sealants cover this chewing surface to prevent any further decay. It does not require drilling or removing of any tooth structure.
The Easy Three-Step Process:
The tooth is cleaned with an abrasive pumice paste to remove any stains or loose debris.
A special cleansing liquid, on a tiny piece of cotton, is rubbed gently onto the tooth and washed off.
Finally, the sealant is painted onto the tooth and cured with a light.
It takes about a minute for the sealant to form a protective shield. One sealant application can last for as long as five to ten years. Sealants should be checked regularly, and reapplied if they are no longer in place. The appointment length for sealants completely varies on the number of sealants to be applied and level of difficulty.
