Make Your Own Toothpaste!

From Oramedia: Dental Self-Sufficiency. This site is a MUST SEE! There are two e-books available there that everyone should read. I am searching for hard copies! Here's some info from the site on making your own toothpaste:
"Proctor and Gamble and Lever Brothers-and any number of other manufacturers-would like us to believe that the only proper way to care for our teeth is with expensive, highly flavored toothpastes that come in non-biodegradable, throwaway, zinc-and-lead (Now plastic -ed.) tubes.'Tain't so !".............
" MAKE YOUR OWN TOOTH POWDER. Thoroughly mix 3 parts baking soda (the cleanser and sweetener) with part salt (the abrasive) and funnel the compound into a short small-mouthed container such as a pop or beer bottle. You'll find that the creation has a satisfying, different taste and leaves your mouth feeling very fresh and soothed. If you'd like, add a few drops of peppermint or wintergreen oil to the concoction - or mix the home "brew" half-and-half with a commercial tooth powder - to give the dentifrice a more pleasant flavor.........
" MAKE YOUR OWN TOOTH PASTE. This formula is simply an extension of the tooth powder recipe: To each half cup of homemade powder, add 3 teaspoons of glycerin, 10-20 drops of flavoring (peppermint, wintergreen, anise, cinnamon or whatever) and 1 drop of food coloring. Mix the ingredients thoroughly in a bowl and add just enough water to make the concoction "tooth-pastey". Spoon the substance into a small refillable plastic squeeze bottle or any container that dispenses easily and won't leak. VoilÁ! Toothpaste!"
"... homemade creation won't be as smooth...but I know you'll find it more satisfying, less wasteful and - above all - less expensive. You'll be able to make a year's supply of toothpaste (for a family of four) at a total cost of around a buck and a half!"
Much more information at that site!
