What Causes TMJ (Temporomandibular Joint Disorder)?

This condition can arise from many factors, such as jaw trauma, teeth grinding, stress, and anatomical problems. The correct identification of the causes is crucial for the success of the treatment to be applied.

Some of the causes are:

  • Teeth grinding or clenching: Grinding or clenching teeth due to stress, anxiety, or sleep disorders can place excessive load on the jaw joint and muscles.

  • Trauma: Blows to the jaw, face, or head from accidents or sports injuries can cause this condition.

  • Malocclusion (Bad bite): An improper alignment of the upper and lower teeth can lead to an unbalanced load on the jaw joint, causing problems.

  • Joint inflammation (Arthritis): Joint conditions such as rheumatoid arthritis or osteoarthritis can affect the TMJ.

  • Stress and anxiety: Intense stress can lead to tension in the jaw muscles, triggering or worsening TMJ symptoms.

  • Poor posture: Incorrect postures, such as sitting at a computer for long periods, can cause tension in the neck and jaw muscles.

  • Displacement of the jaw joint disc: The displacement of the cartilage disc located in the jaw joint can lead to this condition.

  • 缺失牙:缺失牙或不合适的义齿可能破坏颌部的咬合。

How to Treat TMJ (Temporomandibular Joint Disorder)?

轻度病例可通过休息、锻炼和压力管理等居家方法缓解。然而,若病情转为慢性且严重,则可能需要使用口腔矫治器、物理治疗,在极少数情况下还需要手术干预

The treatment approaches used are:

  • Pain relievers and anti-inflammatory drugs: Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce pain and inflammation.

  • Muscle relaxants: Can be used to reduce tension in the jaw muscles.

  • 咬合板或夜磨牙垫:可使用定制透明护牙套来防止磨牙或咬牙习惯,并减轻颌关节的负担。

  • Physical therapy: Exercises can be performed to strengthen the jaw muscles, increase flexibility, and teach correct jaw movements.

  • Stress management: Relaxation techniques, yoga or meditation can be used to reduce the effect of stress on the jaw muscles.

  • Injections: In cases of severe pain, corticosteroid or Botox injections can be administered into the joint.

  • Surgical intervention: Very rarely, when other treatment methods are unsuccessful, surgical options (arthroscopy or open surgery) may be considered.
