If the large face is caused by the enlarged biting muscle, you can play Botox, which can block the conduction between the nerve and the muscle, making the muscle atrophy, to achieve the purpose of the smaller face. If the large face is caused by the oversized jawbone, osteotomy can be performed to make the face smaller. After wisdom teeth extraction, you need to pay attention to oral hygiene, and if you feel that the large face shape affects your aesthetics, it is recommended that you go to the hospital for examination and standardized treatment.
