What is TMJ?
The temporomandibular joint (TMJ) is a complex articulation of the movable lower jaw (mandible) and the base of the skull (temporal bone) that make it possible to open and close your mouth. Located on each side of your head, your TMJ is a ball and socket joint, with an intervening disc, that works together along with supporting jaw muscles and ligaments to help you to chew, speak, and swallow.
What is TMJ Disorder?
Temporomandibular disorders (TMD) are a common group of related pain conditions involving the TMJ, jaw muscles and associated structures.
What are symptoms of TMD? 
- Pain in the TMJ or jaw muscles
- Joint sounds such as clicking or popping
- Limitations in jaw movement
- Tension in face or neck
- Headaches, especially in the temples
What causes TMD?
Possible causes may include arthritis, dislocation, injury, tooth or jaw alignment, stress, and tooth grinding.
What are treatment options for TMD?
Diagnosis is essential before treatment. Most TMDs are self-limiting, so a conservative approach is best including: eating softer foods, avoiding repetitive function (such as gum chewing, biting nails, ice-chip chewing), modifying pain with heat packs, practicing relaxation techniques to minimize jaw tension such as meditation or biofeedback. If necessary, your dentist may recommend exercises to strengthen your jaw muscles, medications (anti-inflammatories, analgesics, muscle relaxants, anti-anxiety drugs) or a night guard or bite plate to decrease clenching or grinding. Very rarely is a surgical intervention (such as arthrocentesis, arthroscopy) required.
