TMJ Dysfunction Explained


What is the Temporomandibular Joint (TMJ)?
The TMJ is located directly in front of your inner ear, below your temple,

and is a part of the body we use many times during the day when we talk, yawn, eat, drink or chew (see diagram). Usually, you are only aware of this joint when it becomes painful.


What causes TMJ Dysfunction?

The pain and tenderness of TMJ dysfunction can be caused by the disc in the joint moving out of place and causing pressure on sensitive structures around the joint.

Other causes of TMJ Dysfunction include:

  • Clenching or grinding of the teeth, both during the day and while sleeping at night
  • Poor posture, leading to strains or overuse of muscles in the face and neck
  • Inability to relax
  • Poor diet
  • Lack of restful sleep
  • Arthritis
  • Fractures
  • Alignment or structural problems present since birth
  • Injuries to the face, head or neck, such as concussions, facial blows, or motor vehicle accidents

The pain of TMJ dysfunction can be sharp, searing and catching, or dull and constant. It can be extremely debilitating

Other symptoms include:

  • Ear pain, or fullness of the ears
  • Facial pain
  • Sore, tight, tender jaw muscles
  • Temple, cheek, tooth or jaw pain while swallowing, yawning, talking or chewing

Physiotherapy and TMJ Treatment

Are there treatment options?

Fortunately, a trained Physiotherapist can help by teaching you relaxation, stretching and strengthening exercises for the face, head and neck muscles. These exercises can also help to augment the effect of the appliance or mouth guard your dentist may have already provided to you.

Your program may include one or more of the following:

  • Stretching and strengthening exercises of the jaw, head and neck
  • Postural correction, relaxation and breathing exercises
  • Manual stretches and mobilizations of the jaw and neck joints
  • Ultrasound and electrical stimulation to improve healing
