Article about what Oprah Winfrey has in her medicine cabinet
I've been using Eco Dent Toothpowder for over a year now and love it! And, it doesn't have flouride. I specifically use the Extra Brite:
SpecialCare line of specialty toothpowders (Res-Q-DenT®, TartarGuard®, and ExtraBrite®) contain additional ingredients, such as CoQ10, Antibacterial Enzymes, Zinc, Bee Propolis, or Peroxide, for enhanced health and cosmetic benefits.
