A Fissure Sealant is a plastic resin that is bonded to the depressions, pits and deep grooves in your tooth’s chewing surface. Fissure Sealants are usually placed in permanent molar and premolar teeth (i.e. the back teeth).

 

When fissure sealing a tooth, the grooves of the teeth are filled and the tooth surface becomes lovely and smooth; the sealant essentially acts as a barrier, protecting enamel from plaque and acids.
