Dental sealants are plastic resins that bond and harden in the deep grooves on your tooth’s surface. When a tooth is sealed, the tiny grooves become smooth, and are less likely to harbor plaque. With sealants, brushing your teeth becomes easier and more effective against tooth decay.
Sealants last from three to five years, although it is fairly common to see adults with sealants still intact from their childhood. A dental sealant only provides protection when it is fully intact, so if your sealants come off, let your dentist know, and schedule an appointment for your teeth to be re-sealed.
