I actually prefer a tooth powder to a toothpaste for many reasons. There is no worry over shelf life since there are no wet ingredients. It is easily stored in a shaker container. Also, it has no actual contact with the toothbrush so it is easily and hygienically shared with family members. And, it's quick and easy to make!
