is it possible for braces to cause temporomandibular joint disorders (tmj)?

Likely not: While orthodontics can exacerbate an already existing (but perhaps asymptomatic) TMJ disorder, it should be a very short term reason. It has been shown through study that tmd is neither caused by or fixed by orthodontics. There can be many reasons for having the disorder, but its likely origin is not braces. See your orthodontist about it, or a dentist who is specially trained in tmd.

Yes: Orthodontic treatments to stable relationships can be part of the correction for TMJ problems. Orthodontics that place the joint in a compromised position can be part of the cause.

Stretched or deranged ligaments and cartilaginous disc of the TMJ are not treatable by orthodontics. Creating a stable occlusion puts the joint into a repeatable and functional position, but has no real effect upon cartilaginous/discal derangements or the ligaments that define the limits of movement. The above illustration is not of the TMJ, but looks to be that of the knee.

Provided original answer
Compression of the posterior bilaminar zone can distort the biomechanical locking principle of this tissue and allows the disc to be displaced or dislocate by the condyle. The bite can cause the joint to move in this position and orthodontics can alter the bite to also cause this problem. Orthodontics done to the wrong joint position can be a cause, whereas orthodontics done to the functional joint position can be an answer.

Yes: This is an unfortunate but small risk, of having orthodontics as an adult.
Dr. Paul Grin
Pain Management 36 years experience
Definitely, no: Recent studies dispute the popular belief that a bad bite or orthodontic braces can trigger TMJ disorders. There is no scientific proof that orthodontic treatment leads to TMJ problems. Ask your orthodontist for more information.

Yes: Yes, possible. Make sure your ortho treatment is being done by a board certified orthodontist. Consider getting a second ortho opinion.

What should I look for when choosing a joint brace to use while playing sports?

Comfort: Selecting a simple sport brace provides added comfort, awareness and reassurance with performance. Braces that truly stabilize a joint can be restrictive and don't guarantee avoidance of injury. In the absence of an injury or chronic condition, i'd find one that was comfortable and keeps me aware of the joint to help avoid injury and maximize performance.

Does wearing a brace ruin your joints after a long time?

Depends on the joint: It depends on the joint and the reason the brace is being worn. The danger is that the muscles supporting the joint will become weak and stiff, so the joint does not have the support it needs.
