On the surfaces of all molars and premolars are natural pits and grooves called fissures. Bacteria in plaque that live in these grooves, produce acid which causes tooth decay.
Fissure sealants are applied to these surfaces to help protect teeth from plaque, acids and tooth decay.
What exactly is a fissure sealant and when should they first be applied?
A fissure sealant is a plastic coating that is applied by a Dental Professional.
As the back molars are more susceptible to decay, they are best applied in Children at age six and then again at thirteen soon after their permanent adult teeth have erupted.
Fissure sealants may also be applied to adult teeth to further protect them from tooth decay.
Wouldn’t brushing be enough to clean these grooves?
No. The bristles of a toothbrush are too large to reach into some of these grooves, by applying a sealant to the tooth’s surface, no plaque can get in.
How is a fissure sealant applied and how long do they last?
The teeth, usually the back molars are thoroughly cleaned and dried first before the sealant is applied to the surface.
The liquid sealant is applied to the tooth’s surface which then flows into the fissures. It is then set with an ultra violet light to set the sealant.
It is painless procedure.
