How are TMJ disorders diagnosed?
TMJ disorders can be difficult to diagnose. There are no standard tests to diagnose most of the disorders that fall under that title. A doctor may refer you to a dentist, or an ear, nose, and throat (ENT) specialist to diagnose your condition.
- X-rays. X-rays of the jaw and teeth usually involve you biting down on a small mouthpiece as your dentist moves an imaging machine around your head. These X-rays will allow your dentist to see the bones in and around your jaw, as well as your teeth placement.
- CT scan. A CT scan of the jaw allows your doctor to see the bones and joint tissues in a more advanced way than a regular X-ray.
- MRI. An MRI of the jaw will reveal if there are problems with the structure of the jaw. An MRI, or magnetic resonance imaging scan, uses a magnetic field to show detailed images of organs and tissues.
