Tooth Paste.

This is something that goes in your mouth multiple times a day and should be checked for gluten. Nowadays they do sell certified gluten free tooth pastes. It’s really hard to trust anyone though. I bought Tom’s brand tooth paste that said gluten free on it but then I tested it with my Nima tester and it can back positive for gluten. So frustrating. This is the brand I currently use and have tested with my Nima.
