A fissure sealant is a varnish layer which is placed on the biting surface of at risk teeth. This varnish flows into the fissures and creates a shallower and smoother biting surface which is lower risk for experiencing food impaction or a plaque build up.


Sometimes your dentist in Smile Hub Dental Clinic may recommend placing a fissure sealant on a tooth that has already begun to decay as this varnish will prevent further spread of the tooth decay.

Is fissure sealing necessary?

Fissure sealants are a quick and easy treatment that will only take a few minutes to complete but it depends on the age and cooperation of the child, as the tooth being sealed must be kept dry so the child must be able to try keep open for a few seconds.

How is fissure sealant done?

Fissure sealants are a completely pain free procedure and require no anaesthetic to be completed. The tooth is polished, washed and dried with air before an etching gel is placed on the tooth for a few seconds. This is then washed and the tooth is dried again. The dentist will then apply the sealant which is then cured or set with an ultraviolet light. The same procedure will be repeated on all teeth that need to be sealed.
