<<Disclaimer: Verify this information before applying it to your situation.>> Hi group, I am summarizing what I received, alot of people took their own toothpastes with them to make sure they would be okay for the cleaning, some said to use just the pumice with water, while the general thought was to call ahead and have the dentist call and check their products, or give you the numbers to do it. I trusted my doc. to check into it, (that doesn't happen very often, that I trust someone else) and my son had his appt. and no ill side effects. It was interesting though, as I was talking to the dentist, I never said celiac, I just explained that he cannot have gluten, and the dental hygienest said " MY sister and nephew have something similar, only they have celiac disease" I about fell over, not too many people even heard of it, let alone know someone. So that is my summary plus a little more, thanks for all the help, once again, you all came through for me! Kathy in Iowa
