Researchers reveal that the female sex hormone estrogen is involved in the occurrence. Change in the rapid circulating levels of estrogen hormone is correlated with the cause. Lower levels of estrogen may trigger the pain to a much higher extent. Due to elevated levels of estrogen, the inflammation of the Temporomandibular Joint occurs which causes much pain.
  5. TMJ may be caused due to associated conditions like rheumatoid arthritis, juvenile arthritis, osteoarthritis and another similar group of related bone disorders.
  6. Jaw Clenching, gritting of teeth, nocturnal bruxism, various psychosocial factors like stresses are also some of the causative factors.

Apart from the above-mentioned causes, there some oral and facial disturbances causing TMJ disorders which are extremely painful. They may be an erosion of the disk of the temporomandibular joint or moving out of its proper alignment. It may occur if the joint’s cartilage is damaged due to arthritis. If the joint is damaged by some serious injury, TMJ disorder may also occur.
