Anyone know good ways to whiten teeth?

Anyone know any good affordable products or home remedies that work ?
--------------------
use baking soda infact arm and hammer has a great tooth paste and it whitened my teeth.you could also use crest whitening strips but not too often because it weekens your teeth. and i know this sounds super gross but you should try brushing your teeth with dove soep.it really works after a few weeks you could even look it up it does work.but use that for only your teeth then wash your mouth with toothpaste afterward like you would noramaly do.for some reason the soep gets rid of plaqe better than a toothbrush. also never use salt it eats away at your enamle and drinks .also if you ask this question on google you ind a lot of answers from other peoples yahoo's,you might find my answers are all the same for whitening.oh and too much coffe really is hard on your teeth. in pharmacys they cell these weird mini tooth brushes for people who are on the go.whenever you are done drinking coffi you can brush your teeth with it.good luck
