Sealants are a tooth coloured coating that is applied to the biting surface of the back teeth. The grooves on the top of the molars are very deep and is a good area for bacteria to live in and multiply. Even with great oral hygiene some of these areas will still get a cavity because the bristles of the tooth brush can not get to these deep areas. Dental sealants act as a barrier against decay-causing bacteria.
When applied it fills in the pit and groves and makes a smooth surface. Easy for a tooth brush to keep clean. The application of a sealant is quick, easy and painless. No drilling or freezing are required. Sealants also cost less than having a cavity filled.
After having a sealant placed you should continue to brush and floss properly.
