Sealants are a preventive dental material that is placed on the chewing surface of the permanent teeth, most commonly the molars and premolars, to help protect them from bacteria and acids that contribute to cavities. These teeth have grooves and depressions that attract food and plaque, and it is hard for regular tooth brushing and flossing to prevent particles from getting stuck in these areas. Dental sealants are usually placed on children’s molars and premolars when they first erupt, however, they can also be placed in adults at risk for caries to add extra protection for these grooved and pitted areas. They are easily placed by the dentist, dental assistant or dental hygienist and do not require anesthesia.
