Dental sealant (also known as fissure sealant) is a thin, plastic coating that is painted on the grooves and pits of teeth. They are most commonly used on the chewing surfaces, where most of the grooves lie, however, they can also extend to the sides of the teeth depending on any additional fissures or pits that are found there. Children can get sealants on their premolars and permanent molars as soon as they come in to protect their teeth during cavity-prone years. We also seal adult molars if they don’t show any signs of decay. They last for several years and protect your teeth from decay.
