What is TMJ, and Is Botox a Viable Treatment for It?

TMJ is a painful condition of the jaw that can be disturbing if not addressed. The temporomandibular joint connects your skull to your jawbone, and it works like a hinge that slides back and forth. There are two joints, located on both sides of your jaw. Not only can TMJ lead to pain; it can also limit the mobility you have in the muscles that are responsible for jaw movement.
