I have TMJ disorder and my oral surgeon told me that there is nothing I can do. Is this true?

Dentistry, neurology, physical therapy and psychology—there are a variety of quite different treatment approaches.

The temporomandibular joint is susceptible to all the conditions that affect other joints in the body, including ankylosis, arthritis, trauma, dislocations, developmental anomalies and neoplasia. Although treatment is often similar to other joints in the body, some variations exist.

While conventional analgesic pain killers such as paracetamol or NSAIDs provide initial relief for some sufferers, the pain is often more neuralgic in nature which often does not respond well to these drugs.[citation needed]

An alternative approach is for pain modification, for which off-label use of low-doses of Tricyclic antidepressant that have anti-muscarinic properties (e.g. Amitriptyline or the less sedative Nortriptyline) generally prove more effective
Examples of reversible treatments are:

Over-the-counter pain medications, used according to manufacturers’ instructions.
Prescription medications prescribed by a healthcare provider.
Gentle jaw stretching and relaxation exercises you can do at home. Your healthcare provider can recommend exercises for your particular condition, if appropriate.
Stabilization splint (biteplate, nightguard) is the most widely used treatment for TMJ and jaw muscle problems. However, the actual effectiveness of these splints is unclear. If an oral splint is recommended, it should be used only for a short time and should not cause permanent changes in the bite. If a splint causes or increases pain, stop using it and tell your healthcare provider. Avoid using over-the-counter mouthguards for TMJ treatment. If a splint is not properly fitted, the teeth may shift and worsen the condition.
Mandibular Repositioning Devices can be worn for a short term to help alleviate symptoms related to painful clicking when opening the mouth wide but 24 hour wear for long term may lead to changes in the position of the teeth which can complicate treatment. A typical long term permanent treatment (if the device is proven to work especially well for the situation) would be to convert the device to a flat plane bite plate fully covering either the upper or lower teeth and to be used only at night. Full mouth reconstruction, or building up of teeth to achieve the proper bite relation is not supported by strong evidence based studies.
My dentist told me I had it..I would have never known. I had no symptoms.
