How long does it take to heal after biting the inside of the mouth?

The healing time for biting the inner lining of the mouth mainly depends on the severity of the injury and individual care measures. Generally, if the bite is mild, the wound is small, and deeper tissues are not involved, healing typically occurs within about a week by maintaining good oral hygiene—such as frequent rinsing, eating a bland diet, and avoiding spicy or irritating foods. However, if the bite is severe, causing damage to deeper tissues along with noticeable bleeding or swelling, the healing process will take longer. In such cases, in addition to maintaining oral hygiene, it is important to seek medical attention promptly for wound cleaning and possible suturing, and to use antibiotics as prescribed to prevent infection. With appropriate treatment and care under a doctor's guidance, the wound usually heals within approximately two weeks.
