Sealants protect the grooved and pitted surfaces of the teeth, especially the chewing surfaces of back teeth where most cavities in children are found. Made of clear or shaded plastic, sealants are applied to the teeth to help keep them cavity-free.
Even if your child brushes and flosses carefully, it is difficult—sometimes impossible—to clean the tiny grooves and pits on certain teeth. Food and bacteria build up in these crevices, placing your child in danger of tooth decay. Sealants “seal out” food and plaque, thus reducing the risk of decay.
