<<Disclaimer: Verify this information before applying it to your situation.>> Marcia, My sister and my mother wear those plastic contraptions to keep them from grinding their teeth at night. This Christmas, while visting my mother-in-law, she also pulled out the same device before she went to bed. I'm not celiac, but seem to have the other kind of gluten intolerance that is a toxicological reaction to the protein fractions, and doesn't involve the immune system. I'm benefiting from gluten-free but am not very successful at getting my teeth-grinding family to try it! Susan Owens
