Explain about dental sealants?

Submitted by: Murtaza

Sealants are a thin, plastic coating that is painted on the chewing surfaces of teeth usually the back teeth (the premolars, and molars) to prevent tooth decay. The painted on liquid sealant quickly bonds into the depressions and groves of the teeth, forming a protective shield over the enamel of each tooth.
