Oh, man, I'm sorry you're stuck getting a band. My first time around I had bands on all my back teeth, but this last time we were able to use only brackets. Be warned, having bands put on is no fun at all--it doesn't hurt, exactly, but there's a lot of pressure, and it feels like your tooth is being scraped away. It's not.

Anyway, you'll get used to the whole thing, I promise. And, yeah, it's amazing how fast teeth can move when they're motivated.
