Sealants are a common preventive treatment in dentistry. Some teeth have fine grooves or pits that accumulate plaque, not because the person doesn't brush, but because the grooves are too narrow to adequately clean them. When plaque accumulates, it can lead to cavities and other types of tooth decay. Sealants can help prevent cavities from forming in these deep grooves. To apply sealants, a plastic material is applied to the tooth, filling these narrow grooves and preventing the cavity-causing buildup.
Sealants are generally done on children and typically placed on the molars. No anesthetic is needed to apply sealants, which makes them quicker, easier and less expensive than a filling. Dentists, as well as hygienists, are able to place sealants. Since they are considered a preventive procedure, most insurance companies will cover them at 100%.
