<<Disclaimer: Verify this information before applying it to your situation.>> Hi List: The summary about my son having a tummy ache & the possibility of Aquafresh causing a gluten reaction..... * Several listers suggested Tom of Maine toothpaste & that the kids love it (Note from Wendy: I'm going to buy some. I just bought Crest, but I think I'll get this instead for my sons ... if I can find it.) * A couple listers use Aquafresh & have no ill effects. One stated her son uses it with no adverse reactions. * One lister said every time she used it, she didn't feel great afterwards. She switched to Arm & Hammer. Thanks gang, Wendy, Exton, PA
