I've been gluten free for 3 months, and after having my blood sugar go insane for the first 2 months, I am finally healing and feeling good. A friend stayed with me for 3 days recently and only ate gluten containing foods twice, a sandwich and a hamburger bun. She was really careful to clean up afterward and not share utensils or double-dip into the peanut butter jar. We also ate at the mall food court (but packed our own lunches, my friend eating her wheat bread sandwich across from me. I did touch her ziploc bag briefly), then took a trip to Whole Foods. At the end of the shopping trip I began experiencing some mild gluten symptoms which have continued for 2 days so far. Is it possible for me to be that sensitive to a bread crumb? Could I have touched something at Whole Foods? Was the table at the food court contaminated? I'm new to this gluten free diet, live alone, and have not dared to eat out yet, so I'm not sure how sensitive a person can be or if maybe I did accidentally eat something (but I can't think of anything I ate that was new). Does anyone else react to such minute things?

I know gluten is a problem for me, but I tested negative for celiac with 2 blood tests. I'm awaiting the results of an intestinal biopsy. One symptom I have that I attribute to the effects of gluten is bad teeth (eroding enamel and teeth that break easily- 2 in the past 11 months). Did anyone experience an improvement in dental health after going gluten free, or has the damage already een done?

I have really bad teeth (and from what I'm learning, that's pretty common). I have been gluten free for a few weeks, but just discovered I react to corn too. I can't find a toothpaste made for sensitive teeth that doesn't have corn in it. Any suggestions?
