A dental sealant is tooth-coloured plastic film that is professionally applied to the deep grooves (fissures) on the back teeth (molars) where tooth decay most often starts.
The bacteria in plaque live in these grooves and make acid which causes tooth decay. Dental sealants assist in preventing the build up of plaque acids on the enamel surface of teeth and they are of value in the prevention of tooth decay.
A good time to apply sealants is soon after permanent teeth are fully erupted (after 13 years of age). Discuss with our dentist whether this will be beneficial to you.
