Gingiva The gingiva consists of the mucosal tissue that lies over the mandible and maxilla inside the mouth They surround the teeth and al veolar bone and provide a seal around them

Periontal ligament is a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which it sits O These fibers help the tooth withstand the naturally substantial compressive forces which occur during chewing and remain embedded in the bone

Alveolar bone Also referred t as the al veolar process is the thickened ridge of bone that contains the tooth sockets on bones that bear teeth The al veolar process contains a region of compact bone adjacent to the periodontal ligament called lamina durat It is this part which is attached to the cementum of the roots by the periodontal ligament
