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.
Sealants are typically applied to children’s teeth after their permanent teeth have erupted as a preventive measure against tooth decay. However, adults can also 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 from three to five years, although it is fairly common to see adults with sealants still intact from childhood.
