Fissure Sealants

The grooves and depressions that form the chewing surfaces of the back teeth are extremely difficult (if not impossible) to clean of bacteria and food particles. Decay is caused when the bacteria reacts with the food – acids form and break down the tooth enamel, causing cavities.

Almost all (97%) of the tooth decay in the permanent teeth of Irish 8 year olds occurs on this biting surface (North South Survey of Children’s Oral Health in Ireland 2002).

Tooth sealants protect these susceptible areas by sealing the grooves and depressions, preventing bacteria and food particles from getting to these areas. Sealant material is a resin typically applied to the back teeth, molars and premolars and areas difficult to clean. Once in place the sealant will protect this vulnerable surface.
