Horizontally retained wisdom teeth should be extracted as early as possible if there are lesions or symptoms of disease in the surrounding tissues. If the horizontally retained wisdom teeth are located near important blood vessels, nerves, or tissues, and if there are no obvious symptoms, they can be retained for observation, as described below. 1. Removal: If the horizontally retained wisdom teeth are decayed or cause diseases or symptoms such as pericoronitis, food impaction, alveolar bone resorption, etc., it is recommended to remove them as soon as possible to terminate the further development of the disease. 2. Retention and observation: If the horizontally retained wisdom teeth are completely embedded in the bone with no special symptoms, or if they are close to important blood vessels, nerves, or tissues, which may cause greater trauma during extraction, the wisdom teeth can be retained for observation and regular follow-up. It is recommended to go to the hospital to receive regular treatment.
