Sealants protect the surfaces of teeth with grooves and pits, especially the chewing surfaces of the back teeth where most cavities are found. Sealants are made of shaded, tooth colored plastic and are applied to the teeth to help keep them cavity-free.
How do sealants work?
Even if your child brushes and flosses carefully, it is difficult, sometimes impossible, to clean the tiny grooves and pits on certain teeth. Toothbrush bristles are just too thick to reach into the pits and fissures. Food and bacteria build up in these depressions, placing your child in damage of tooth decay. Sealants "seal out" food and plaque, thus reducing the risk for decay.
