Does Crest's 3D white toothpaste really work?!

It doesn't work nearly as well as the white strips do (which really aren't too bad, but I understand you not wanting to use them). It's just not concentrated enough to do much. You can use baking soda too, which helps a little, but still doesn't whiten them as much as white strips. If you're concerned and really want white teeth, talk to your dentist about good options.

peroxide or any other harsh cemicals are not the way to go. I use a natural product I found on the web and my stains are gone, I really recommend this to anyone who has stains or yellowing. When I had tried peroxide last year I think it looked like it could work but I got canker soars after the first time I used it. This one is made from a super concentrate neem formula and it didn't hurt my gums at all and I was pretty amazed at how white it's getting my teeth. The only place I've found it so far is on this site.

Whitening tooth paste doesn't really whiten your teeth from their original shade. It just does a better job at removing surface stains which keeps your teeth white if they already are.

So in short, yes..But not the way you want.

Yes it do work very good
