Fissure sealants (protective coatings)
Fissure sealants are protective plastic coatings which are applied to the back teeth. They are then hardened with the application of a concentrated beam of ultraviolet light. They are permanent and can remain in place for many years.
Fissure sealants have been used in dentistry for many decades and provide a very effective means of preventing tooth decay. They are usually placed in the adult molar teeth soon after they erupt. The sealant forms a smooth, protective barrier, by covering all the little grooves and dips in the surface of the tooth. Dental decay easily starts in these grooves if not protected.
