I really can't possibly begin to imagine over 500 uses
By itself with a bit of water is fine, with a splash of hydrogen peroxide instead is even better. Good Lord, over the past fifteen years or so how many of the national brands of toothpaste have come out bragging about now with baking soda? Or peroxide? Or both, if you want to pay a premium nearly five bucks a tube. Which would be stupid when it costs literally just pennies to concoct your own.
Of course, you miss out on what the commercial toothpastes also bring along with, the assortment of mystery chemicals and stuff that might give you pause putting it in your mouth. Even the obligatorily added fluoride, turns out not so good for the choppers after all, not so much harmless as toxic instead; before fluoride was deemed a "cavity fighter," it was used as an insecticide and rat poison. I think I'll take my chances doing without, thank you. Yikes.
Amazing so much stuff from tube to brush to mouth to drain to waterways and finally on out into the rest of the environment... not to mention so many billions of tubes ended up in landfills. All of this avoidable with just mushing up a teaspoon of baking soda with a quarter teaspoon of hydrogen peroxide. That's all it takes for a healthier mouth and a healthier planet.
Sure it's not minty fresh, though I don't mind the saltiness of it really; I kind of like it. But I've read from others who have jazzed it up also adding to the mix a drop of peppermint oil or even something to do with orange rinds or extract or whatever. Pretty much anything, I suppose, that makes it more tasty. Me, I'll stick with the basic just two recipe ingredients. It's cheaper that way, but that's just me.
