Stress and bruxism: stress could lead to tooth grinding (bruxism) that wears down the teeth, as well as to TMD.
Poor Posture: frequent slouching or hunching over, you may not only hurting your back, but also pushing your jaw out of alignment, causing symptoms of TMD. Poor posture puts the spine in a position that stresses the lower jaw shifts forward, causing the upper and lower teeth misalignment, and the skull to move back on the spinal column. If not addressed, pain and inflammation in the muscles and jaw joints will develop when the mouth opens and closes.
Stress & Clenching. Clenching your teeth while worrying about filing your something could be placing a burden on the TMJ.
Super Sizing: Taking bites that are too big could lead to jaw and muscle pain &aggravate already existing TMD.
The 1st line of treatment is a splint or mouth guard (gouttière). The TMJ splint is worn to reduce stress on the jaw, allow the muscles to function optimally and/or to cover allowing the lower jaw to be repositioned into the socket properly. If you don't wear it, the condition will get worse, you may require surgery.
Oral habits like teeth grinding (bruxism), or clenching the teeth tires the muscles and they go into spasm causing TMJ disorder.
Depending upon the type of TMJ disorder you are having, the treatment is recommended. Treatment includes jaw rest, application of heat and ice to relieve pain, taking anti-inflammatory medication or physiotherapy for the muscles of face which includes stretching or relaxing the muscles. You are also expected to change your life style if it is quite stressful and is aggravating the condition. You can learn stress reducing techniques. You are expected to change your food habits like avoid eating chewing gum, hard to chew food and you should avoid opening your mouth too wide (wide yawning or loud singing). The basic aim of all the treatment is to give maximum rest to the joint.
So if one follows the doctor`s recommendation then in most of the cases surgery can be avoided and the TMJ joint problem can be treated.
Oocclusion is one of the most common predisposing factor. If by any reason the occlusion is affected, like person got the new filling which is high or he got the tooth extracted. There is a chance that the muscles go into spasm and patient gets TMJ disorders.
so this splints,or braces are used to reduce spasms that is made by the occlusion
