Answer:
It is like a constant sore after lifting weights or sprinting on your cheek muscles. Another pains only two teeth touch, which at first is just extremely annoying until a couple hours when it starts to hurt too talk and it doesn't get much better until there off. Plus there are all the cold sores, the constant torture that won't go away. If you are getting "internal headgear" my only suggestion, is to try too open your mouth really wide if the ends are not screwed in until they come loose. If its screwed in ( like mine was) , fiddle with the screw and bar until the screw comes off. Orthodontists gave up on me I broke it too many times. They almost always move your jaw forward for cosmedic (looks) purposes, unless your bite is severally out of line, even then there are other ways to put your jaw in alignment.
