Causes of TMJ Disorder (TMD)

What are the causes of TMD?

TMJ disorder and facial pain is a common, sometimes very disconcerting problem experienced by many people. It can be a complex problem with many contributing factors such as:

  • Jaw muscle spasm and inflammation due to over use or clenching / bruxing
  • Jaw muscle spasm following lengthy dental procedures
  • Jaw joint stiffness, inflammation and sometimes locking
  • Altered bite position due to a dental restoration / filling that is too high
  • Trauma to the jaw due to a blow to the face or a car accident
  • Upper neck joint stiffness from poor posture or other injury
  • Neck and upper back muscle spasm and tightness
  • Poor head on neck posture
  • Unsupported / inappropriate posture while sleeping or during waking hours
  • Stress causing more clenching (bruxing) or tightness of all associated muscles
  • Obstructive sleep apnoea may lead to night time bruxing
