So I guess there is a tooth whitening charcoal powder that is supposed to remove coffee, tea, wine and tobacco stains, as well as improving oral health and freshening breath. Wow- quite a product. But I don't think this video represents exactly how it's supposed to work. I'm glad this woman is getting a laugh out of this. I'd just stick to toothpaste from now on - less chance of the contents doing whatever the heck they did to her here.
