What Is A Sealant?
A sealant is a clear or shaded plastic material that is applied to the chewing surfaces of the back teeth.
Why Are Sealants Necessary?
The back teeth have depressions and grooves on the chewing surfaces of the enamel. These irregularities are called pits and fissures. They are impossible to keep clean, because the bristles of a toothbrush cannot reach into them. Therefore, pits and fissures are snug places for plaque and bits of food to hide. By forming a thin covering over the pits and fissures, Sealants keep out plaque and, thus, decrease the risk of decay.
Pit and Fissure Sealants Prevent Cavities:
Dental Caries (tooth decay) is the most wide-spread dental disease. Your dentist can help prevent or reduce the incidence of decay by applying sealants to your teeth.
What Causes Decay?
Decay is caused by dental plaque, a thin sticky, colorless deposit of bacteria that constantly forms on everyone's teeth. When sugar is eaten, the bacteria in plaque produce acids that attack the tooth enamel. After repeated acid attacks, the enamel breaks down, and a cavity (hole) is formed.
