Teeth whitening?

i got my braces off and my teeth arent as white as they used to be. Any suggestions for whitening on a budget?
--------------------
Well, "budget" is pretty subjective, but my dentist turned me on to Tres Whites, and they worked great. He charged me $100 for a package (7 trays for 7 applications to both uppers and lowers) but I've since found them online A LOT cheaper -- http://www.dentist.net/tres-white-melon.… You only need to use them once or twice a year, and they worked great for me. None of the stuff at the grocery store (white stripes, Rembrandt toothpaste, etc.) seemed to work at all on my teeth, but I did find that the Rembrandt paste helped my teeth stay whiter longer after using Tres Whites. They come in three flavors, and it only takes 45 minutes to an hour a day for one week to see major improvement. The only downside is they make your teeth pretty sensitive for a while. Lasts another week or so after you're done. It's uncomfortable, but not intolerable by any means. Seeing as the dentist charges over $700 for custom trays, this seemed like a bargain. Not to mention the fact that he's the one that told me they work just about as good as the $700 job. Good luck! Straight teeth are great, but straight white teeth are awesome.
