Dentist Anchorage AK, Dr. Terry Preece, discusses dental sealants which refer to a plastic resin that a dentist bonds into the grooves of the chewing surface of a tooth as a means of helping to prevent the formation of tooth decay and cavities. Tooth decay is caused by the bacteria found in teeth, also known as that white film that forms on a person's teeth. The longevity of dental sealants can vary. An adult's teeth can be sealed, although this procedure is typically utilized as a preventive measure for children to help protect their teeth during those years when they are most likely to experience tooth decay. Any dental sealants that remain in place and intact for three to five years would be considered a success; however, sealants can last much longer.
