The gingiva, periodontal ligament, cementum

Gums, periodontal ligament, cement and alveolar bone form the tissues surrounding the teeth, and join them to the alveolar bone. Each of periodontal tissue plays a vital role in the functioning and retention of teeth. Gum provides a seal tissue around the cervix, the part of the teeth and covers the alveolar ridge.

Periodontal ligament supports the tooth in its socket, provides nutrients and touch sensations of the tooth, and supports cement, and alveolar bone of the tooth socket. In cement anchor periodontal ligament of a tooth and sealing the ends open dentinal tubules. Cement education compensates for wear of the teeth due to the occlusion of exhaustion. Alveolar bone forms bony sockets that support and protect the roots of the teeth. ..
