<<Disclaimer: Verify this information before applying it to your situation.>> I have gotten a great deal of info from the list since I started on gf diet last sept (self diagnosed) and I'm grateful for the help. If I had paid more attention to the postings over the last few months I might have avoided and accident with rice dream. Now I 'm backing to reading all the posts and need info on toothpaste. I use pearl drops extra whitening and dont seem to have problems. I am very sensitive as one 8oz glass of rice dream was enough to do me in. so whats the deal as far as toothpaste goes..do I need to change? thanks David G. (in Miami)
