Tooth sealants are a clear or shaded plastic resin applied to the chewing surfaces of the posterior teeth where most cavities in school age children are found. Even if your child brushes and flosses carefully, it is difficult, if not impossible to completely clean the tiny grooves and pits located in the surfaces of these teeth. Food and bacteria build up in these crevices placing your child at an increased risk of tooth decay. The sealant "seals" out this food and plaque, thus creating a smooth surface that the brush can adequately cleanse, therefore reducing or eliminating the risk of decay.
The teeth most at risk of decay, and therefore most in need of sealants, are the permanent six and twelve-year molars. The primary "baby" molars and permanent premolars usually exhibit fewer and shallow grooves which often can be satisfactorily cleaned with normal brushing, and do not require sealants. However, any tooth with grooves or pits may benefit from the protection of sealants. Dr. Tom can advise you as to your child's unique situation.
Research shows sealants can last for many years if properly cared for. If your child practices good oral hygiene and avoids grinding his/her teeth or biting hard objects, the sealants will last longer. Dr. Tom will evaluate the sealants during regular dental visits and recommend re-application or repair when necessary.
The application of a sealant is quick and comfortable. It takes only one visit. The tooth is first cleaned. It is then conditioned and dried. The sealant is then flowed onto the grooves of the tooth and instantly hardened with a special light. Your child is able to eat immediately after the procedure.
The treatment is very affordable, especially in view of the valuable decay protection it offers your child. Most dental insurance companies cover sealants. Our staff can check with your benefits provider to help you determine the exact cost of sealants for your child.
Remember, sealants only protect the chewing surfaces of the permanent molars. Brushing, flossing, balanced nutrition, limited snacking, and regular dental visits are still essential to maintain a bright, healthy, cavity-free smile for a lifetime.
