There is a possibility of self-healing in mild cases, but most of them still need to be corrected. 1. Slightly circumcised in childhood may have self-healing when milk teeth are replaced. It is due to incorrect breastfeeding posture that causes the child’s pseudo-mandibular protrusion, and this kind of circumcision, even if it exists during the period of milk teeth, has the possibility of normal occlusion after the permanent teeth come in. Part of the circumference can be corrected by biting and warping method under the guidance of the doctor. 2. Most of the cases require medical treatment, such as braces or orthognathic surgery. It is necessary to make a personalized plan for correction after a clear diagnosis of the severity of the circumcision in a regular medical institution. It is recommended to go to the dental hospital for examination. Even in childhood, the circumcision needs to be corrected in time, otherwise it will cause problems in the development of the jaw and affect the correction in the future.
