Anthony Yeh hit the nail on the head perfectly. When you bite the inside of your lip or cheek and traumatize the area, it becomes inflamed and swells up slightly. This small swelling causes the area to be more likely to get hit again and again. This can cause a traumatic ulcer with repeated and sustained injury.
