Know About TMJ / TMD


"T M J" stands for Temporo-mandibular-joint. 'TMD' simply means 'TMJ Disorder'.

The function of the TMJ is to hold the lower jaw to the head within a certain  boundary and guide the jaw movements for chewing, talking, singing, yawning,  breathing, swallowing, keeps airway open while sleeping, and maintains the body  posture and balance, etc.

All body joints (TMJ, hip, knee, wrist, ankle, finger etc.) have either hinge movement  or circular movement or a combination of the two.  However, TMJ has not only hinge  and circular movement, but also has a sliding movement: condyle (head of the jaw  bone) moves in and out of the joint socket: Ginglymoarthroidal (hinge-gliding) joint.


TMJ may be the most active part in our body next to the heart and lungs. An  average  person moves the TM joint 2,000-2,500 times a day/night. If someone likes  to talk  excessively or chew gum habitually, it may move 5,000 times or even 10,000  times a  day.




If this complex joint receives constant distress beyond the adaptive  capacity, the harmony of the system can be disturbed, TMJ and disc can become displaced, joint and disc can be damaged and clinical symptoms may be manifested to the jaw, face, head, neck, shoulder, back, and to the whole body through the musculo-skeletal-nervous system.


The TMJ is one of the most complex joints in the body. It is composed of a large group of delicate small muscles, nerves, blood vessels, ligaments, tendons,  cartilage, disc, synovial fluid, retro-discal tissue and each part work in harmony with other parts like a “ Symphony Orchestra”.
