A fissure sealant is a protective coating that is applied to the pits and grooves of a tooth to help protect the tooth from decay. It is usually white in colour and lasts for several years. These are commonly applied to the teeth of children who are at a higher risk of developing cavities.
Fissure sealants are an incredibly effective form of cavity prevention in the grooves of teeth. 75% of decay starts in the pits and fissures of the molars. Deep grooves in the teeth can be difficult to clean with a regular tooth brush.
This procedure is done under rubber dam isolation. This is a straight-forward procedure which usually takes 30-40 minutes. No anaesthetic is necessary for this procedure. The grooves of the teeth are carefully cleaned out and conditioned and the sealant is applied and set with a curing light.
