We Tried It: The Best Ways to Whiten Your Teeth at Home

totally agree - I was excited to see some before & afters, but only one specified how many shades lighter their teeth got. It's hard to see the difference in the photos - but maybe if you used a shade indicator to show us how much it really changed. Bummer!

I agree with all these comments. The whole "experiment" was b.s. and does not help with their credibility whatsoever. I now expect to see Listerine and Crest ads popping up on the site.

Why are all the first photos taken in very Yellow backgrounds and the "after" photos are all just a bit fuzzy and taken under whiter light. It's deceptive and hard to see the real results.

This slidshow was not helpful at all. The pics could have been bigger the lighting was just terrible. And no one said if they liked or diliked or even if they would use it again VERY UNHAPPY

The differences in the lighting of the subjects makes it impossible to compare the "lightening" of the teeth from the before to the after. There is no way to tell if the products actually worked. Enhancing the yellow with yellow lighting is misleading.
