The tooth socket, or |alveolus|, is the bone cavity in the |mandible| or |maxilla| in which the |teeth| are anchored. The |teeth| are anchored in these sockets by the root canals, or |cones|, of the |teeth|. The nourishing ~blood~ vessels and ~nerves~ pass from the tooth socket into the tooth by way of the |apical foramina| in the bottom of each root cone.
