What causes TMJ disorder?
It is commonly thought that TMJ pain has a ‘multifactorial’ cause. It can be due to
⦁ Tension or overuse of jaw muscles (like during clenching or grinding during sleep or biting nails)
⦁ Wear and tear to the cartilage inside the joint, mainly happens in older people due to arthritis.
⦁ Injury or trauma to the joint itself or elsewhere in the jaw.
⦁ Teeth that don't fit together properly, out of line, or missing teeth, cause occlusion problems, i.e. the way the teeth meet when your jaws bite together.
⦁ If your lower jaw is in the wrong position, the muscles that move the jaw have to work a lot harder and can get tired. This leads to muscle spasm.
What are the signs of TMJ disfunction?- Pain in the jaw joints and facial muscles.
