A fissure sealant is a preventive white resin coating that is bonded to the tooth to seal over grooves, fissures and pits. The aim of a fissure sealant is to prevent bacteria, and the sugars they eat, from penetrating into these vulnerable, impossible to clean areas of the teeth.
A fissure sealant is a painless and quick procedure to undertake. It normally involves the cleaning of the area to be sealed, followed by the application of a dental etch. Then the fissure sealant material is flowed into the area and set using a blue light.
The lifespan of a fissure sealant is dependant upon the bonding process, the forces that it is subjected to, as well as the quality of the enamel it is bonded onto.
Fissure sealants are most commonly recommended to children in the first couple of years after the eruption of a permanent tooth. This is when they are at their most vulnerable to decay. However, we will also seal grooves in adult’s teeth if we consider them to be at risk of decay.
