Discolored Teeth?

I'm getting the braces off in about a month's time. Hooray!

But now I have a new concern. What if, after the brackets come off, it turns out they've left white spots on my teeth, while the areas around the brackets are stained? Am I making any sense? I'm just worried that my teeth would look discolored to the point where you can see where the brackets have been. Has anyone encountered this problem?
