i used some crest whitening strips 2 years ago and it worked well. the side teeth were much more yellow than the front teeth, which is an unfortunate effect of whitening strips :/
raynor suggested baking soda / peroxide when brushing. i've been meaning to try it, but havent gotten around to it.
How many strips did you have to use? for how long? I actually have a handful of whitening strips that I got from a freebie somewhere.. Think I tried them for 3-4 days in a row but gave up for not seeing any results whatsoever.
