What are sealants? If my child gets sealants, does that mean she won get cavities?
A sealant is a clear or shaded plastic material applied to the chewing surfaces (grooves) of the back teeth (molars/premolars), where four out of five cavities in children are found. The sealant acts as a barrier to food, plaque and acid and helps protect decay-prone areas of teeth. Sealants can help prevent decay, but they are only part of the solution. Even with sealants, children must continue to properly brush, floss and eat a healthy diet to keep cavities away.
