A. The best thing to do would be to book an appointment with the dentist whom may refer you to a hygienist or even a periodontal specialist. In some cases bone grafts can be carried out to replace the bone you have lost around the tooth. A hygienist may be able to give you the advice you need to prevent the tooth worsening and to help prevent any other teeth going the same way. In the mean time, keep this area as clean as possible.
