This stuff works so great! I notice a difference even when I just use it once in a while. Really leaves teeth feeling clean, too. For the people that say how messy it is, well, yeah, it's messy. It's powder. All you have to do is be careful when you open it. Duh! I like to scare my kids with my black teeth while using it haha!
