Spots on your teeth
If you notice white, yellow, or brown spots on your teeth that you can’t attribute to coffee, tea, or smoking, they could be a sign of celiac disease. The autoimmune disorder is a reaction to eating gluten—a protein found in wheat, rye, and barley—leading to stomach damage and trouble absorbing nutrients. One of these nutrients is calcium, which plays a big role in healthy teeth. “It can be seen in as many as 40 to 50 per cent of new pediatric celiac patients, compared to six per cent of the healthy population,” says Hilary Jericho, MD, a specialist in pediatric gastroenterology at the University of Chicago. Your doctor should check any spots that are symmetrical and scattered across most of your teeth.
