Teeth whitening - can someone explain different methods and which is best?

Hey, can someone please explain the different options for teeth whitening, and which is best/easiest? :) Thanks!

someone an hour ago asked if a toothpaste could whiten her teeth. here's what I wrote...i think it applies to your question as well! sadly, NO toothpaste, no matter what they say will truly whiten your teeth; at least not enough to dramatically notice! they removed a little surface stain, but not much more than when the hygienist polishes your teeth at your cleaning appointment. anyway, the best way to get teeth whiter is (honestly) Crest whitestrips or similar product from a reputable company. they're only about $30 and they work fairly well! if that doesn't do it for you, you can have it "professionally" done at a dental office,but this can cost $200, 400, even 600 dollars. if you do have it done at an office, the take home trays are less expensive but just as good as the "laser" whitening (ZOOM! and similar products....) I went to a class last year where the guy who basically inVENTed the whitening tray process that my office and others use came out and said, "Look, the best bang for the buck is over the counter like Whitestrips." there are advantages (and maybe more dramatic results?) from in-office whitening, but try the strips first!
