Injury from eating too hard food

It is common in clinical practice to eat hot or hard food and rub the soft palate, buccal mucosa, or parapharyngeal mucosa when chewing or swallowing, which can immediately form blood blister, thus causing oral damage. At this time, the patient felt a local strangeness or tingling. The mucosal blood blister can be seen by opening his mouth. It is purplish red, the wall of the blister is thin, the size is not restricted, and the shape is different. After the rupture of the blister membrane, the blister membrane was necrotic and detached and showed a bright red ulcer with a clear edge. There was a little secretion on it, and the surrounding mucosa was congested, and the patient felt burning pain. If the damage is too large, the healing will be slow, and granulation tissue will gradually grow on the ulcer surface, and it will heal after covering with fresh epithelium. Traumatic ulcers refer to ulcers caused by long-term chronic mechanical damage such as residual roots and crowns in the mouth, sharp edges of teeth, misplaced teeth, and bad restorations; or caused by long-term self-harmful habits such as cheek cheek, cheek, and lip bite Ulcers. The shape of the ulcer fits perfectly with the stimulus.
