Dr. Guo Huijie
Mouth ulcers caused by accidentally biting the mouth usually take a recovery time that depends on several factors, including individual physical condition, severity of the ulcer, and daily care. Under normal circumstances, such oral ulcers heal within 7 to 10 days. If the individual is in good health and the ulcer is mild, with only slight pain and white blisters, healing may be faster, taking about 7 days. However, if the person has a weaker constitution and the ulcer is deeper, accompanied by severe pain, the recovery period may be longer, requiring about 10 days. During the healing process, maintaining good oral hygiene, avoiding spicy or irritating foods, and ensuring adequate nutrition can help promote ulcer healing.
