Can you have bad tmj with general anesthesia?

Yes: Hyperetension of the jaw point during intubation is certainlyb possibility.

Intubation Can Do It: The anesthesia itself shouldn't have an effect on your jaw joints (tmjs). However, if your mouth has been propped open for a long time, and you've been intubated (a breathing tube placed into your lungs) during surgery, this can place a fair amount of stress onto your jaw joints and cause pain. Sometimes, this can trigger a long-lasting problem. Generally, however, this acute trauma will heal.

Depends: If you have, or are prone to have, TMJ then a general anesthetic can exacerbate this problem. Discuss this with your anesthesiologist before the operation.

Yes: I've see severe TMJ problems after intubation and general anesthesia.
