<<Disclaimer: Verify this information before applying it to your situation.>> I have had consistent canker sores, which doctors and dentists have "waved away" as temporary for the past 15 years. I have been recently diagnosed with Celiac disease after going 1 1/2 years with continuous diarrhea. Needless to say, quite a bit of weight was lost and anaemia set in. Now, I find that, without Gluten, I have not had a single canker! One question, though, how many people get cankers following a visit to the dentist? I questioned my dentist on this, but, at the time, did not know that I was CD. Any ideas?
