Hearing a popping sound in your jaw joints? Experiencing a dull throb or sharp pain? Millions of people worldwide suffer from facial and jaw pain. Correct diagnosis and treatment can be challenging because jaw pain has many potential causes. Doctors must identify the exact cause to provide the best treatment.

Causes

Jaw pain can result from nerve issues, physical injury, or blood vessel problems. Temporomandibular joint disorder (TMJ) is one of the most commonly reported causes. Other causes include:

• Osteomyelitis: An infection in the body that affects bones and surrounding tissues.
• Capsulitis or Synovitis: Inflammation of the joint lining or associated ligaments.
• Sinus Problems: Inflammation of the sinus cavities causing facial pressure and jaw discomfort.
• Vascular pain: Caused when blood supply is disrupted; includes carotid artery dissection and giant cell arteritis.
• Neurovascular pain: In conditions like migraines and cluster headaches, both nerves and blood vessels are involved.
• Tension headaches: Caused by stress, may radiate pain to the jaw.
• Dental issues: Gum disease, cavities, cracked teeth, tooth gaps, or abscesses.
• Teeth grinding or clenching: Often occurs during sleep and can damage teeth and cause jaw pain.

Other factors include lack of nutrients, fatigue, sleep disturbances, and conditions like Lyme disease, lupus, multiple sclerosis, and hypothyroidism.

Treatment varies depending on the underlying cause. Common treatment options include:

• Physical therapy
• Use of a mouth guard
