Tooth Powder is another item you don't see too much anymore. There was a time, years ago, when most Americans used tooth powder as opposed to paste. I grew up in such a household, and I remember all of my relatives using it as well. I'm told tooth powder is actually an ancient product that goes back to Roman times. I believe it is still sold in tins, but there are also some simple recipes for tooth powder you can make from home. I'm not too sure the people at Procter & Gamble and Colgate-Palmolive would be too happy for you to know this though.
Also look for Tim's postings in the Palm Harbor Patch, The Gentlemen's Association, and throughout the Internet.
