Dental sealants are tooth-colored plastic coatings that are usually placed on the chewing surface of permanent molars and premolars.

The pits, grooves, and fissures of the teeth are the most susceptible to decay, and are sometimes are too narrow or deep to be properly cleaned with a toothbrush.  Dental sealants protect and “seal” the surfaces of the teeth, and provide a smooth, easy-to-clean surface that is resistant to decay.
