A sealant is a clear or shaded plastic material that is applied to the chewing surfaces (grooves) of the back teeth (premolars and molars), where four out of five cavities in children are found. This sealant acts as a barrier to food, plaque and acid, thus protecting the decay-prone areas of the teeth.
