Whether this powder will help recover any bone density in my front lower right gums (that's why I can only give four stars at this point) it's too early to say (and will most definitely come back and share the good news if that does happen, then I will give five stars instead of four), but it sure removed major staining from my teeth that I thought I would have to go back to my dentist to have a bleaching treatment. And speaking of bleaching treatment on teeth, that's a plus in this powder: it doesn't leave your teeth hurting with that horrible sensation peroxide does in exchange for a bleaching!
