<<Disclaimer: Verify this information before applying it to your situation.>> I am a diagnosed celiac and in addition, I believe I have a mild case of Sjogren's Syndrome. I had serious problems with my tongue swelling off and on for several months. It's frightening to have your tongue bigger than normal, and also you talk funny. I was referred to an ear, nose and throat doctor who's wife has CD. No diagnosis from him for the swelling tongue. I read some literature on Sjogren's Syndrome which mentioned sensitivity to Dentine gum. Sure enough - no more Dentine and no more swelled tongue. I had been a heavy user. I also steer clear of cinnamon toothpaste. This experience was so weird I wanted to share it to save similar diagnosis problems in others. Ellen Switkes Oakland, Ca
