Dental sealants are thin, protective coatings made from plastic or other dental materials that are applied to the chewing surfaces of the back teeth—primarily the molars and premolars. These areas have deep grooves and pits that can be difficult to clean thoroughly with regular brushing and flossing, making them more susceptible to cavities.
Sealants work by sealing out food particles, plaque, and bacteria, thereby preventing tooth decay. The application is quick, painless, and non-invasive. Typically, a dentist or dental hygienist will clean the tooth, apply an acidic gel to roughen the surface, rinse it off, and then brush on the sealant material, which is hardened with a special curing light.
Sealants are most commonly recommended for children and teenagers as soon as their permanent molars come in, but adults without decay or fillings in their molars can also benefit. With proper care, dental sealants can last several years before needing reapplication.
