<<Disclaimer: Verify this information before applying it to your situation.>> The technical staff at Procter and Gamble in charge of Crest toothpaste (phone 800-543-7270) just told me that all forms of Crest, in all of North America (incl Canada) are gluten free. I had been concerned about this since Julie May posted a note saying that one of the Canadian Celiac groups stated Crest was not GF. The staff-person promised to mail me a formal letter to this effect, and I will post it when it arrives -- this could take a week to arrive, though. As we all know, many companies make claims that are sincere but ill-informed. I hope this is not an example of such a claim. If anyone has ever tested Crest with the home gluten test kit, could you please post the results? Thanks Bill Elkus
