Crohn’s disease and ulcerative colitis can affect other parts of the body besides the colon. Unfortunately, the health of your teeth and gums can also suffer if you’ve been diagnosed with the inflammatory bowel disease (IBD). Unlike ulcerative colitis that is also a form of IBD, Crohn’s disease can affect any part of the gastrointestinal tract including the lips, mouth and even the esophagus, but either form of IBD can cause symptoms other than bowel disease. Some medications cause your mouth, tongue or throat to be sore or develop ulcers and other oral problems.
