Many factors may cause this condition such as:

Teeth grinding
Stress
Articular disc displacement
Trauma “Jaw injury”
Arthritis

The diagnosis largely depends on medical history and physical examination, but other tools can be used such as:

Panoramic x-ray (imaging using x-ray to show all teeth and jaw joints).
Magnetic resonance imaging (a device that uses magnetic fields is used to get an image of the muscles, ligaments, and cartilage).
Cone-beam computed tomography (a scan in which thousands of images are taken to produce 3-dimensional images of teeth, jaw, and facial bones).

In most cases, this condition resolves spontaneously without treatment, but other cases need treatment such as:

Conservative therapy: the patient is educated to deal with the condition by eating soft food, adding warm compresses on painful areas, and resting the jaw.
Behavioral therapy: Making behavioral changes to relieve stress.
Medications:
NSAIDS (ex: Naproxen)
Antidepressant (ex: Amitriptyline)
Anticonvulsants (ex: Diazepam, Clonazepam, Gabapentin)
Muscle relaxants (ex: Orphenadrine, Metaxalone)
Physical therapy: special exercises and devices are used to stretch and strengthen the jaw muscles.
Devices: to prevent teeth grinding.
Surgery: different types of surgeries can be done if other options did not work.
