what are sealants
Tooth Sealants. Sealants are a thin coating 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 grooves of the teeth, forming a protective shield over the enamel of each tooth.owever, adults without decay or fillings in their molars can also benefit from sealants. Typically, children should get sealants on their permanent molars and premolars as soon as these teeth come in. In this way, the dental sealants can protect the teeth through the cavity-prone years of ages 6 to 14.
