<<Disclaimer: Verify this information before applying it to your situation.>> Thanks for the responses. I received several on Sensodyne toothpaste but only one on Snapple beverages which assured me that both the diet and regular are GF. All respondents on Sensodyne who responded to the gluten status said it was GF. No one reported any bad effects from using, however, several recommended other brands that they use and prefer which are GF. Other brands suggested are Aqua Fresh, Toms, Arm & Hammer, Oral-Gel Gold and Crest. All are the formulas for sensitive teeth. Thank you all for the help. Renee C. Beverly Hills, Calif.
