i think they hurt because i need braces and i ahve a appointment for some but im not sure they are gonna kill me lol!

They will be sore for a couple of day. But I recommend taking about 3 pain pills like a one hour or half a hour before the appointment. So they don't start hurting after the braces are put on. At the end, it will be worth it! You will have a wonderful smile.
