An ulcer resulting from biting the inner lining of the mouth is known as a traumatic oral ulcer, primarily caused by bacterial infection following the injury. The etiology of oral ulcers is complex; local trauma may merely serve as a triggering factor, while underlying immune deficiency or vitamin deficiencies predispose individuals to developing such ulcers. Oral ulcers are generally self-limiting, and pharmacologic treatment can alleviate pain and reduce inflammation, thereby promoting more rapid healing of the ulcerated area.
