Does tmj have anything to do with sleep apnea or could tmj cause any problems happen cuz of this?

TMJ: Not usually. It can be a cause of headaches though. It can also lead to dental issues if grinding your teeth is the cause.

Could be: Generally TMJ patients have their jaw in a position that when they lay back, the jaw drops back further closing more of the airway. Thus sleep apnea. A bionator appliance positions the jaw in a therapeutic 3 dimension position thereby opening the airway and also treating sleep apnea, .

Could be: Obstructive sleep apnea can have bruxism (tooth grinding) associated with it. This is thought to be a mechanism related to opening the pharynx to allow for brething. Have you had a sleep study to determine sleep apnea? Mouthguards can be made as a starting point to diagnose tm problems.

Possibly: Need more info, but the treatment for the sleep apnea may create or exacerbate tmj/tmd symptoms. If wearing a CPAP machine with tight straps or an ill-fitting mask, the pressure on the lower jaw (mandible) may be displaced or dislocated enough to a position that can cause a dormant tmj/tmd syndrome complex. Also, wearing a mouthpiece for sleep apnea, if not designed properly can cause tmj/tmd.

Yes: Research has suggested that the stress caused by sleep apnea may trigger jaw clenching and grinding.

Sleep Disorders: Nighttime grinding or bruxism is consider a central nervous system sleep disorder. New studies are showing strong correlation of bruxism to obstructive sleep apnea. http://www.sciencedaily.com/releases/2009/11/091102171213.htm.

Perhaps: Sometimes treatment for sleep apnea (like CPAP apparatus or sleep apnea mouthguard) can cause or aggravate a TMJ problem. If as a component of your TMJ you developed erosion of your condyles and caused your jaw to drop back, it could contribute to sleep apnea.
