i heard that if you make a solution of baking soda and peroxide and put it on your teeth it whitens them pretty fast, and being that i have a pretty big date tonight i was going to try it, i just thought id ask here to see if it really works. so does it?

you probably need more then a few hours with one treatment for anything you do

Isnt peroxide toxic ? (in a big enough dose)

Uh, putting peroxide in your mouth is a BAD idea...it'll whiten your teeth, and your gums. Probably best not to .

Yeah, this thread has the potential to offer some pretty sketchy advice. OP, I would suggest looking at legit dental sites for advice on teeth whitening.
