Fissure Sealants

Dental fissures are the grooves that naturally occur on the biting surface of teeth.

All molars and premolars have fissures to some degree. If the fissures are very deep and narrow, toothbrush bristles cannot fit or reach inside to clean the teeth and remove food particles. Consequently, plaque develops and causes tooth decay.

A fissure is five times more likely to develop decay than other tooth surfaces. In children and adolescents, the chewing and biting surfaces of molars and premolars are most vulnerable.

Fissure sealants are plastic coatings that fill the fissures and protect teeth from dental plaque and acids. When a tooth surface is completly sealed with a fissure, protection is 100%.

Treatment is painless and non-invasive, with a coat of the sealant applied to a cleaned tooth. The liquid sets in minutes and forms a physical barrier that stops food, bacteria and plaque acids from contacting the tooth surface.

Maintenance of a fissure seal: A regular check-up as recommended every 6-12 months. This allows the early detection of sealant loss or tooth decay. A sealant can be easily replaced if partially lost due to wear and tear.
