Tongue ulcer

Tongue ulcer is a type of mouth ulcer. Tongue ulcers, commonly referred to as "oral anger" or "aphthous ulcers" in the folk, are a type of localized ulcerative injury of the oral mucosa characterized by recurrent episodes. They can heal on their own and can occur anywhere in the oral mucosa. It is more common in the mucous membranes on the lips, cheeks, soft palate, or gums of the mouth. Single or multiple round or oval ulcers of various sizes occur. The surface is covered with gray or yellow pseudomembrane, the center is depressed, the boundary is clear, and the surrounding mucosa is red. Micro-swelling, ulcerative local burning pain is obvious, with periodic, recurrent, self-limiting characteristics. Tongue ulcers are also known as recurrent aphthous stomatitis (RAS), recurrent oral ulcer (ROU), recurrent ahthae, or canker sores.
