My mother was a real working cowgirl when young, on her dad's ranch. Her recipe for toothpaste is simple: three parts baking soda, one part fine salt (I use sea salt) in a small container with a tight screw-on lid. Shake before use. Wet toothbrush and dip, apply to one side, dip again for other side, brush gently all over. Don't get powder too wet or it clumps but shaking before using again fixes that. The salt makes you salivate which helps kill germs and loosen bits between teeth. Rinse very well or tongue will feel dry. I've used this for over fifty years and have never had a cavity. True!
