Sealants are a thin, protective coating that adheres to the surface of your back teeth. Sealants are not a substitute for brushing and flossing, but they can keep cavities from forming and may even stop early stages of decay. According to the Surgeon General, sealants have been shown to reduce decay by more than 70 percent.
In our office we apply sealants to the 6-year molars as soon as the child is old enough. The procedure is not painful, but can be tedious and requires that the child cooperate in keeping the area isolated and dry. We place sealants on 12-year molars as soon as they are fully erupted into the mouth.
