Part of the TMJ is a small, flexible piece of cartilage between the skull and the jaw bone to cushion them. When this gets displaced, the bones of the jaw can rub together, leading to inflammation. Typically this will cause clicking, popping, locking and joint pain. It can also lead to headaches and neck pain.
How Your Teeth Can Cause Jaw Pain and Headaches
In the first video you can see a healthy bite. The teeth are coming together properly and the TMJ (jaw joint) is working smoothly.
When the TMJ stops working properly it can cause inflammation and pain in the joint. The muscles around the jaw may also overcompensate trying stabilize the joint, which can cause muscle fatigue, spasms and pain also in the head, neck or ear.
The main reasons for TMJ problems are:
A Bad Bite
When the teeth don’t align properly, it can cause the jaw to close unevenly, putting strain on the joint and the surrounding muscles. It can also shift the cushioning cartilage disc between out of position (see second video).
Teeth Grinding or Clenching (Bruxism)
Chronic clenching or grinding puts repetitive pressure on the TMJ, which can lead to strain, wear and displacement of the cushioning cartilage. A lot of bruxism occurs while a person sleeps.
Structural Issues
A less common cause of TMJ pain are structural issues such as uneven jaw development, arthritis and trauma.
