It is recommended that the tooth be extracted if the root is longitudinally fractured or if the inflammation of the pulp is too severe to be treated, while a crown fracture or root fracture that can be treated with root canal therapy can be retained. If the tooth is fractured, it can no longer be retained and needs to be extracted after radiographs are taken. If the tooth root neck or root tip fracture can be fixed by jaw adjustment and observed, the pulp is not inflamed, or after the pulp inflammation, the inflammation can be eliminated after root canal treatment, it is not necessary to extract the tooth.

Tooth fracture specific need to be extracted to the hospital to check the oral cavity and the condition of the tooth can only be judged, it is recommended to go to the hospital as soon as possible to deal with.
