Dental Sealants

What are 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.

Which teeth are suitable for Sealants?

Permanent molars are the most likely to benefit from sealants.  The first molars usually come into the mouth when a child is about 6 years old.  Second molars appear at about age 12.  It is best if the sealant is applied soon after the teeth have erupted, before they have a chance to decay.

How are Sealants applied?

Applying sealants does not require drilling or removing tooth structure.  The process is short and easy. 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.  Dr. Herman then shines a light on the tooth to help harden the sealant.  It takes about a minute for the sealant to form a protective shield.

Are Sealants visible?

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.
