There are a variety of symptoms that may be linked to TMJ/TMD. The most common symptom is a dull, aching, intermittent pain in the jaw. Other symptoms include, but may not be limited to:

• Changes in the way the upper and lower teeth fit together
• Earache and/or headache
• Jaw muscle stiffness
• Limited movement (mandibular hypomobility) or locking of the jaw (lockjaw)
• Painful clicking, popping or grating of the jaw when opening or closing the mouth
• Radiating pain in or around the eye, ear, jaw, neck or temporal region
• Spasms that cause the mouth to remain tightly closed (trismus)

Evaluation for TMJ/TMD often begins with physical examination, but may also involve muscle testing, radiographic imaging or range of motion measurements.

There are multiple nonsurgical and surgical treatments available for TMJ/TMD. Nonsurgical options may include medications, physical therapy or removable occlusal orthotic appliance therapy. In an individual with persistent TMJ/TMD symptoms despite nonsurgical management, surgical treatments include, but may not be limited to:

• Arthrocentesis (joint aspiration) – Minimally invasive procedure that involves inserting a small needle into the joint to irrigate fluid and remove debris
• Arthroplasty – Restores range of motion by repair or replacement of the joint; replacement involves partial or total grafts or implants. Examples of US Food & Drug Administration (FDA) approved prosthetic joint replacement devices include, but may not be limited to: TMJ Concepts Patient-Fitted TMJ Reconstruction Prosthesis System, TMJ Fossa-Eminence Prosthesis System and Zimmer Biomet Total Mandibular Joint Replacement System.
• Arthroscopy – An endoscope is placed inside the joint for diagnostic purposes and/or to remove any inflamed tissue or adjust parts of the jaw that are misaligned
• Arthrotomy – May encompass a range of surgical procedures including debridement or disc repair, repositioning or replacement
