Sealants are typically applied to children’s teeth as a preventive measure after the permanent teeth have erupted as a way to prevent tooth decay. However, adults also can receive sealants on healthy teeth. It is more common to seal “permanent” teeth rather than “baby” teeth, but every patient has unique needs, and your dentist will recommend sealants on a case-by-case basis.
Sealants typically last for several years, although it is fairly common to see adults with sealants still intact from 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.
