The periodonteum (or periodontal membrane) is a layer of connective tissue around a tooth which helps anchor it in the |alveolus| (tooth socket). The periodonteum is similar to the supportive periosteal membrane in bones, as it carries the ~nerves~ and ~blood~ vessels which supply nourishment to the |pulp| cavity of the tooth. Inflammation of this membrane and its surrounding tissues is called periodontal disease, and results primarily from poor dental hygiene, though genetic factors may also play a role in one's susceptibility to such disease.
