Sealants are liquid coatings that harden on to the chewing surfaces of teeth and make the surface smoother.

There are no longer any locations on the chewing surface of the tooth that the bristles of a toothbrush can't access and clean. Since dental plaque can be removed more easily and effectively, there is much less of a chance that tooth decay will form.

Application

Sealants are applied by first cleaning the tooth surface. The procedure is followed by "etching" the tooth with a chemical substance, which allows the sealant to better adhere. The tooth is then painted with the sealant material.  After the sealant is applied, a warm light source is directed to the site to promote faster drying. Sealants usually need re-application every few years.
