Celiac disease is the body’s inability to process gluten properly, leading to chronic inflammation and damage to the small intestine. Although poor oral health does not cause celiac disease, repeated bouts of dental issues may be an indication of celiac disease. In fact, 85% of people with celiac disease have excessive enamel loss. This leads to a long list of symptoms, including symptoms that involve your teeth and gums. If you frequently suffer canker sores, cavities, or discolored teeth, you may want to get evaluated for celiac disease, particularly if you also experience intestinal problems.
