im glad you posted that im about to look into gluten intolerance's again for a relative,
im interested to find out if GMO anything tests as tolerant for anyone, would not be surprised if most GMO was intolerant to most people
i read all the posts on that page, one poped out
someone referenced
http://thedr.com/ dr tom o'bryan he appears to be a leading authority
also dr tom done "gluten summit" not worth the 100 dollars i have it ill watch it again and post a summary,
i remember looking into al the gluten celiac debate for a relation and it all pointed to some off the same factors discussed above
i tested a relation for all grains and oats tested best recommended a diet with some oat groats soaked and fermented in dulse spring water cooked in pressure cooker tested optimal, DE weak soln every 3 days for reducing any proinflammatory cytokines and DE mouth rinse, aloe vera interally every few days to help leaky gut and tooth/gum health and overall regenerative tonic, microbiome optimisation, he is quite old and he has a carer who doesnt bother so he is slow to improve
intersting is that he is one of the last old style self sufficient irish gaelic smallholders, remembers drawing blood from cows when times were tough, has a lot of old land lore, grew and eat a lot of oats main grain in the wet cold west ireland, he was told to stop eatin oats as celiac and eats all that random gluten free stuff which ive always had reservations about, most of the gluten free products were not good for him and advised him which ones best
that why self testing by muscle or pendulum so important
also more relevant to OP is that Celiac Disease is correlated with google "Celiac Dental Enamel"
Celiac Disease: Oral and Dental Manifestations
https://www.nsdental.org/Portals/0/Images/celiac%20disease-dental%20and%20oral%20manifestations.pdf
no wonder is always been obvious that healthy teeth = healthy all round
so if we figure out easy cheap biohacks fo regenerating enamel, curing abcesses, healthy gums then it a good indicator that pathogen biofilms that can originate in cavities, leaky gut, diet and environmental intolerance's are minimised, and microbiome and overall health optimised
