This procedure is usually done on the children’s freshly pre-fractured remaining grinder teeth. The reason for this is that these are the teeth that most often have the deep grooves and pits that are most prone to decay, and by “sealing” them we can prevent decay.
The most appropriate time would be immediately after the breakthrough.
It is very important to remember that groove sealing can only be performed on an intact, healthy tooth surface when cavity shaping is not yet necessary.
After professional cleaning, the teeth and the grooves are made ready to receive the groove sealant and the grooves are sealed by placing it on the tooth surface.
