Dental Sealants

Dental sealants are thin plastic coatings that are applied to the grooves on the chewing surfaces of the back teeth to protect them from tooth decay. Most tooth decay in children and teens occurs on these surfaces. Sealants protect the chewing surfaces from tooth decay by keeping germs and food particles out of these grooves. 

 

Permanent molars are the most likely to benefit from sealants. The first permanent molars usually erupt behind the last primary molar when a child is about 6 years old. It is best if the sealant is applied soon after the teeth have erupted, before they have a chance to decay. 

 

How It's Done

After the tooth is cleaned, a special gel is placed on the chewing surface for a few seconds. The tooth is then washed off and dried. Then, the sealant is painted on the tooth. The dentist or dental hygienist also may shine a light on the tooth to help harden the sealant. It takes about a minute for the sealant to form a protective shield. 

 

Sealants can only be seen up close. Sealants can be clear, white, or slightly tinted, and usually are not seen when a child talks or smiles.

 

Who Needs Sealants?

Dental sealants are primarily designed for children. As soon as the posterior (back) permanent teeth fully erupt, sealants should be placed to protect them from getting tooth decay.
