A broken tooth root does not necessarily require tooth extraction, but should be determined according to the location of the root fracture, root length, alveolar bone height. 1. Root fracture in the crown 1/3 area: If the root is fractured in the crown 1/3 area, according to the length of the root and the height of the alveolar bone, we should see if we can perform orthodontic traction or crown lengthening to make the gums have enough dental tissues to be restored. 2. Root in the middle 1/3 or root 1/3 fracture: if the root in the middle 1/3 or root 1/3 fracture, need to closely observe the tooth whether there are symptoms, if necessary, fixed, endodontic surgery, if there is obvious repeated loosening or fistula, etc., then need to be extracted, and then restored. Root broken tooth whether to pull the tooth is recommended to consult a professional doctor.
