The temporomandibular joint (TMJ) connects the jawbone and skull and may be impacted by inflammatory arthritis. TMJ dysfunction is estimated to occur in approximately half of patients with rheumatoid arthritis (RA). (1)TMJ disorders — a type of temporomandibular disorder or TMD — can cause pain in your jaw joint and in the muscles that control jaw movement. For most individuals, the pain and discomfort associated with TMJ disorders can be effectively relieved.

Symptoms of TMJ dysfunction (2,3)

  • Pain, swelling, and tenderness in one or both temporomandibular joints
  • Limited mobility in the jaw
  • Aching in and around the ear
  • Aching facial pain
  • Difficulty chewing
  • Locking of the joint
  • Clicking sounds emanating from the jaw
  • Grating sensations

Treatment and Lifestyle Changes

Treatment is similar to treatment for any joint affected by RA or inflammation.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to reduce pain and inflammation while DMARDs are used to prevent progressive joint destruction. (4) Individuals can also implement a number of lifestyle changes to help alleviate symptoms. (5)
