Hello, I'm glad to answer your question. Pit and fissure sealing is a method of coating a material on the cross-shaped pit and fissure of teeth and curing it with light to protect teeth from food erosion. 6~8 years old is the most suitable age for children to do pit and fissure sealing. At this time, the child can cooperate well, and the permanent teeth have just sprouted and need protection.

Suggestion: It is the best way to prevent tooth decay, so it is very good. I hope I can help you and wish you health.
