The temporomandibular joint, TMJ,  connects the lower jaw, called the mandible, to the bone at the side of the head—the temporal bone 

The TMJ is different from the body’s other joints. The combination of hinge and sliding motions makes this joint among the most complicated in the body. Also, the tissues that make up the TMJ differ from other load- bearing joints, like the knee or hip. 

Disorders of the jaw joint and chewing muscles fall into three main categories:

  1. Myofascial pain involves discomfort or pain in the muscles that control jaw function. 

  2. Internal derangement of the joint involves a displaced disc, dislocated jaw, or injury to the condyle. 

  3. Arthritis refers to a group of degenerative/ inflammatory joint disorders that can affect the TMJ. 

TMJ  signs and symptoms were more common and severe in females than male

Pain is the most common symptom of TMJ problems, although not everyone gets pain. Symptoms can include: 

  • Pain in the jaw joints and facial muscles 

  • Clicking, grinding or locking of the jaw 

  • Headaches & Dizziness 

  • Difficulty opening or closing the mouth comfortably 

  • Pain on talking, chewing (especially hard food) & yawning 

  • Ear pain, ringing in the ears (tinnitus) & hearing loss
