Temporomandibular Joint (TMJ) Dysfunction

What is it ?

The temporomandibular joint (TMJ), is the most used joint in the body. Your TMJ’s (jaw joints) are involved in many ways such as when you chew your food, talk and breathe. Temporomandibular joint dysfunction is when the jaws do not function as they are supposed to due to imbalances at the jaw muscles and joint causing pain, clicking, locking and/or abnormal joint movements.

What Causes It?

  • Displacement of the TMJ articular disc
  • Dysfunction of muscles around the jaw
  • Poor bites e.g. underbites or overbites
  • Bruxism: nocturnal grinding of teeth which increases pressure in asymmetrical movement
  • Stress
  • Poor head position while sleeping
  • Poor neck and head posture
  • Removal of wisdom teeth

Symptoms

The most common symptoms are:

  • Pain or tenderness of your jaw.
  • Jaw locking, making it hard to open or close your jaw fully.
  • Popping or grinding of the jaw
  • Pain around your ear.
  • Suffer from headaches, dizziness and upper neck pain.
  • Difficulty chewing or pain while chewing.
