Temporomandibular Joint (TMJ) Disorders
What is TMJ disorder?
The temporomandibular joint (TMJ) connects the lower jaw (mandible) to the skull and allows for movement like opening and closing the mouth, chewing, and speaking. TMJ disorder occur when the joint or muscles around it are injured, overworked, or misaligned, leading to pain and dysfunction. You might hear people call these conditions TMJ. But “TMJ” refers to your actual jaw joint, while “TMD” stands for temporomandibular joint disfunction, or disorder. There’s no singular cause of TMD. Rather, it can be a result of many different factors or a combination of factors.
Common Causes
- Injury or Trauma — A blow to the jaw or head can damage the TMJ.
- Teeth Grinding (Buxism) — Frequent grinding or clenching of teeth, espeicially during sleep, can strain the TMJ. This tends to be one of the most common causes of TMJ disorder.
- Arthritis — Osteoarthritis or rheumatoid arthritis can affect the TMJ.
- Jaw Misalignment (Malocclusion) – If your bite is not aligned properly, it can put extra stress on the joint.
- Stress – Increased stress can lead to muscle tension in the jaw and facial muscles, aggravating TMJ issues.
Common Symptoms
- Jaw Pain or Tenderness to palpation
- Clicking or Popping Sounds when moving the jaw
- Limited Jaw Movement (difficulty opening or closing the mouth)
- Headaches and Migraines
- Earaches (without ear infections)
- Neck and Shoulder Pain
- Facial Pain or Muscle Stiffness
How is TMJ Diagnosed?
- Physical Examination — A dentist or doctor will check for tenderness, swelling, or clicking noises in the jaw.
- X-Rays and Imaging — To check for structural issues, such as arthritis or joint damage.
- MRI or CT Scans — In some cases, these can be used to examine soft tissue and bone in more detail.
