Dental sealants are a special varnish that is place on the back teeth chewing surface to help prevent the development of dental cavities and tooth decay. The top surface of your back teeth is not smooth; it has hills and valleys called pits and fissures. These pits and fissures act as a great hideout for bacteria to linger and cause decay.
The whole procedure is quick and painless. The dentist or hygienist will first clean the tooth and apply an ‘etch’ solution to the surface. This helps the sealant stick to your teeth. Once everything is ready the dentist or hygienist will “paint” the sealant right over the top surface of your tooth and then shine a special light to harden the sealant. Sealants should be check at each regular dental visit and if necessary the sealants can be reapplied.
