I'm getting braces

I just got back from the Orthodontics office. They did all the X-rays, molds, etc. They followed it up with placing these rubber braces between my back teeth. They didn't hurt when they were first put in, but now they are starting to give me a headache! I have to keep them in there for one week! Oh well, this will all pay off in the end. I've always HATED my teeth and now I'm able to do something about it. I want to be able to smile with confidence, not smile and wonder if anyone is freaked out or disgusted by my crooked teeth.
