Families can still sign up their children for free dental care provided through ForsythKids Dental. The Cambridge-based program brings dentists and dental hygienists to Memorial Middle and Jacobs Elementary schools throughout the year and offers exams, cleanings, fluoride treatments, and sealants, according to its director, Dr. Kerry Maguire. “Part of our role is to help children find a permanent dentist home in the community; we don’t consider ourselves in competition” with local dentists, she said. More information about the program is available from the Hull school nurses, she said.
