Yes the pain meds will be liquid, and they are VERY strong so she really shouldn't be in THAT much pain. And as for the wiring .. it doens't hurt at all. you wake up and they're already on. Taking them off wasn't really bad either, it was just weird more so because you hadn't been able to open your jaw at all before. They just put little wires around your braces on the top and bottom .. over my life i've had 16 (yes 16!!) teeth pulled out, and i can tell you right now that they hurt more than getting the wires off!

BTW, my doctors told me too that i would look like i was hit by a truck (his words) but it was not as bad as i had expected! Your face is realy swolen around where they do it, but it by no means looks like that! I know that your daughter's surgery is different than mine was, but try and not get freaked out by how the doctor described it!
