Temporomandibular joint dysfunction (TMD, TMJD)
Temporomandibular joint dysfunction (TMD or TMJD) is a condition affecting the temporomandibular joints (TMJ), which are the two joints connecting your jawbone to your skull. These joints are located just in front of your ears and allow your jaw to open and close, enabling you to speak, chew, and yawn. TMD is characterized by pain and dysfunction in these joints and the muscles that control jaw movement.
The exact cause of TMD is often difficult to determine and can be due to a combination of factors such as genetics, arthritis, jaw injury, or grinding and clenching of the teeth (bruxism). Symptoms of TMD include pain or tenderness in the jaw, aching pain in and around your ear, difficulty chewing or discomfort while chewing, aching facial pain, and locking of the joint, making it difficult to open or close the mouth.
Diagnosing TMD involves a physical examination where the dentist or doctor checks for tenderness, clicking, popping, or grating sounds when you move your jaw. Treatments for TMD vary based on the severity and cause of the symptoms. Conservative treatments include eating soft foods, applying ice or moist heat, and avoiding extreme jaw movements. Pain relievers and anti-inflammatories can also help manage symptoms. More advanced treatments might include dental splints, physical therapy, and in rare cases, surgical interventions.
