My mom got her etsy up and has added two different tooth powders. One is a regular Peppermint recipe, which I think tastes pretty good, and the other one, which I haven't tried yet, is a Cinnamint version. Here is the link for my mom's shop: http://www.etsy.com/shop/NurturedNaturals?ref=seller_info 

Feel free to check it out and give it a try. The tooth powder actually works better than regular pastes, in my opinion, and also naturally whitens your teeth gradually without damaging the enamel. Your dentist will love you for switching!
