It is easier and less expensive to
prevent tooth decay than to treat it. The four major steps in preventing tooth
decay are proper oral (mouth) hygiene; fluoride treatments; use of sealants;
and attention to diet.
A sealant is a thin, plastic
material used to cover tooth surfaces. It protects enamel from attack by
bacterial acids. Sealants are especially helpful on irregular surfaces of the
teeth. They prevent food and plaque from getting trapped on these surfaces.
Sealants
are usually clear or tooth-colored. They do not affect the appearance of a
person's teeth and may last as long as ten years. Some dentists recommend the
application of sealants as soon as a child's permanent teeth appear, in order
to protect the teeth from ever becoming decayed.
