Eco-dent Toothpowder is a very intriguing thing. It's all natural, travel friendly, economial (up to 200 brushings in one bottle!) and it comes in my favorite flavor: cinnamon. So, I bought one recently and, boy, was I in for a surprise. The best way to describe it is that it's like brushing your teeth with Pop Rocks, minus all the sugar. Seriously.
It was more than a little shocking the first time I used it, but I like it more and more with each brushing. I think it's the power of the raw baking soda that give it it's explosiveness, but it cleans my teeth well and it makes me feel very wholesome. :)
