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.
