I had spacers, they were annoying and hurt for a couple days or so that they were in... I also had braces, they really aren't as bad as everyone thinks they are... Sure, they hurt when they're tightened, but it's not the end of the world. You get used to it after a while and you hardly notice they're there (Until you're told that you have green stuff in your braces) - i only had mine on for a year and a half, but i have a friend who had them on for SEVEN years. It all depends on how easily your teeth move.. In a sense, you're lucky if your teeth don't move easily because once you get the braces off, they won't go out of line so easily. Mine move quickly, so if i don't wear a retainer for a few days, my teeth go outta line...
