Abstract: Orthodontic tooth movement is to move the tooth to a desired position in the upper and lower jaw by orthodontic force. In this process, the tooth root may be in close contact with some neural canal structures in the jaw, such as the Mandibular canal and the incisive canal, which may lead to the risk of nerve injury. In addition, because the nerve is located in the nerve canal, the tooth root first contacts the bone cortex, which may also lead to the risk of tooth root absorption. This article reviews the relevant research at home and abroad, and discusses the nerve compression related to orthodontic tooth movement. At the same time, orthodontists need to be aware of the potential risk of neural canal compression and take necessary preventive measures to reduce the risk for related high-risk cases.
