"Anyway, I use a homemade tooth powder for brushing. It contains ground sage, ground orange peel, a few drops lemon EO and a drop spearmint EO, salt and green clay (the kind used for facial masks). Seems to work well, but then, anything containing salt and natural clay or chalk would probably work fine." ~Thats one recipe from a MDC mama.
"it's 3 tbs of baking soda and 1 tbs of salt." ~That's another. (I would think you could add teatree oil or peppermint or something if like that)
