Well, it's actually tooth powder. This is an excellent substitute for commercial toothpaste. It does a better job, promotes a healthier mouth and costs a whole heck of a lot less! Besides, what will you do when your tube runs empty and you can't buy any more? This is a simple recipe that you can make any time from your kitchen pantry.
Homemade Tooth Powder
3 parts baking soda
1 part table salt
optional: add drops of peppermint oil or any other flavor to your liking.
Stir it all together.
Pretty simple. I guess some people really dislike the taste of baking soda. It's never bothered me, but if you find it unpleasant, the flavoring might really help. I added peppermint oil to ours and I really like it. It leaves a cleaner feel and taste in your mouth than any commercial toothpaste I've ever used. Here's a quote from an article by Patrick H. Bellringer that explains pretty well how and why it works so well:
"Baking soda is chemically a base or alkaline substance, the opposite of an acid. When an acid and a base are combined, they react chemically to neautralize each other and form a new substance known as a salt. Baking soda is a weak base and reacts in the baking process to form gas bubbles. The gas bubbles form air pockets in the pastry as the gas dissipates, shich causes the bread/cake to 'rise'. "
"Common table salt is produced by the chemical combination of sodium (Na), a powerful toxic powder, with chlorine (Cl), an extremely toxic gas. The salt produced is known as sodium chloride (NaCl) or common table salt. NaCl is found naturally in nature and is deposited on the floors of evaporating desert lakes. NaCl is required for proper metabolism in all living cells, yet in pure form NaCl can kill all life forms. This is why the salt flats of the Great Salt Lake in Utah, have no life forms living there."
"... Our forefathers used salt and soda as a tooth powder for cleaning their teeth..."
"...the soda will neutralize the organic "food" acids which erode the calcium of the enamel of your teeth and cause cavities. The salt will kill bacteria present in the mouth, and the salt and soda combination will act as an abrasive to clean the plaque and food particles from your teeth. Never will your teeth have been so clean and with no harmful side effects to you..."
