HERE'S ONE FOR YOU
From "Mother Earth News" year???
ToothPowder
To make your own toothpowder, throughly mix three parts baking soda (the cleaner and sweetner) with one part salt (the abrasive) and funnel the compound into a short small-mouthed container such as an empty, washed pop bottle. The creation has a satisfying, differnt taste and leaves your mouth feeling fresh and soothed. If you like it, add a few drops of pepperment or wintergreen oil to the concoction...or mix the "home brew" half and half with commercial tooth powder.
