Why are sealants necessary?
When back teeth are developing, grooves are formed on the chewing surfaces. They are impossible to keep clean because the bristles of a toothbrush cannot reach into them. Therefore, pits and grooves are snug places for plaque and bits of food to hide. Sealants are clear, shaded plastic materials that can be painted onto these decay-prone surfaces of the teeth. By forming a thin covering over the pits and fissures, the sealants keep plaque and food out of the crevices in the teeth, reducing the risk of decay. However, children must continue to brush and visit the dentist.
