A dental sealant is a tooth-coloured coating 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.

The chewing surface of a molar contains natural pits and grooves (fissures) where dental decay occurs most often. The bristles of a toothbrush are too large to reach into some of these areas.

The tooth is thoroughly cleaned and dried before applying the sealant.

The liquid sealant is placed onto the surface of the tooth and flows into the pits and fissures. The liquid is then set with an ultra violet light.

Sealed pits and fissures make the tooth surface smooth and easy to keep clean.

A good time to apply sealants is soon after permanent teeth are fully erupted (after 13 years of age). Discuss with Dr Julia whether this will be beneficial to you.
