Actually, yes! It's "tooth powder". LOL. Old time stuff. It wasn't popular by the time I was born, but my mom and dad used it. It's still around, but hard to find in the USA. I guess we are just too lazy to add the water to it, and make it "paste" anymore. Still, I use baking soda and hydrogen-peroxide to brush my teeth most the time. I smoke, drink Coca-Cola, coffee and red wine. That means toothpaste isn't good enough to keep my teeth white-ish.

But, I do remember the great "toothpaste controversy" of 1974! It was carnage! Bodies everywhere! "Oh! THE HUMANITY OF IT ALL!" {Footnote: This is the exact quote the radio announcer used when the zeppelin HINDENBURG burst into flames in front of him, during a live radio broadcast. It's still used by old people like me for comical effect, although young people don't understand the reference. Most don't even know what a zeppelin is.}
BTW, if you've ever seen The Carpenters, you'll see that Karen, the singer, needed A LOT of tooth paste or powder or both. :)
