My wife has tried most if not all OTC products and none have really given her that dazzling look she was going for.
However of all of them the Crest Whitestrips did whiten them up somewhat. Not the super sparkling white she was going for but it did make a little change, enough that I noticed. Not that she has brown, yellow, or stainded teeth or anything like that.
