Are there any ways to whiten teeth if you have braces?

something cheap easy to do other than brush your teeth everyday(because I do that) any good toothpaste that whitens teeth very well
--------------------
DONT WHITEN WITH BRACES!!!! your teeth could be all discolored when you get the braces off... however, i used a whitening toothpaste constantly and my teeth are fine...but i just did that to make sure they didnt get darker lol but like i said...i know people that have teeth that are many different shades because of whitening...
