You might look into whether you have sensitivities to other foods including gluten free grains - hypoglycemia-type symptoms and persistent fatigue very common with that - best test for sensitivities is the MRT
Had this study in my files: Vitamin D may reduce susceptibility to gingival inflammation through its antiinflammatory effects - http://www.ncbi.nlm.nih.gov/pubmed/16155270 - with some many people deficient it's worth looking at.
Any food can be reactive, including rice. Food sensitivities like everything else are highly individualized, and can occur for a wide range of reasons. The best test for sensitivities is MRT-LEAP, better than 90% accuracy for non-allergic, immune mediated food intolerances. Mucous in stool? Sure sign of inflammatory response. Intolerance of grains can also be lectins, gluten-associated cross reactive foods, numerous other things. The LEAP diet helps begin to sort all this out, heal the gut, and restore some tolerance to gluten-free foods. May need to add on the Cyrex Labs new gluten sens panel (for cross-reactivities) but if you start with a personalized elimination diet like LEAP it will go a long way. Also look into vitamin D for the gingivitis, be sure he's not deficient.
If you want to find out more about what you're reacting to, the MRT test & accompanying LEAP diet would probably help a lot. Many celiacs have co-existing sensitivities that prolong symptoms even if you're eating gluten-free. Although further restrictions might be frustrating, sensitivities can diminish with avoidance and rotation. So adding a LEAP elimination diet to your gluten-free diet could get you feeling a lot better, and then with time you can likely add certain foods back.
You might also consider MRT food sensitivity testing which can pinpoint which foods and chemicals in the diet may be triggering the symptoms. Takes the guesswork out of the process. Any foods can be reactive, even those traditionally associated with a standard elimination diet.
