5Mouth Sores
Many people might not often think of their mouth as a part of the digestive system, but it actually is. That’s why it can also develop canker sores or mouth ulcers just like other areas due to Crohn’s disease. The exact cause is still unclear, but it is associated with systemic inflammation. You might see these sores developing around the gum’s base. Some basic features of the ulcers include oval or round shape, gray or yellow tone, small size, painful, and showing up in groups. Many people often feel pain during flares. In rare cases, the disease could also trigger fluid-filled ulcers or pustules in the mouth. [5]
