A sealant may be recommended by your Smiley Dental Dentist in or around Lowell, Dracut, Methuen, Tyngsborough, Pelham, Lawrence, Boston, Mattapan, Hyde Park, Roslindale, Milton, New Bedford, Fairhaven, Mattapoisett, Acushnet, Rochester, Marion. It involves a simple coating being “painted” on the tooth surface. The sealant protects the enamel of the teeth from acids and plaque, and goes into the deep grooves as an effective barrier, especially for places that cannot be reached by flossing and are difficult to reach with brushing.
