If the pulp is not exposed, a temporary crown can be placed to protect the tooth, and a filling can be placed after sufficient restorative dentin has been formed. If the pulp is exposed, a root canal should be performed, followed by a crown. Any permanent restoration of the tooth should be done 6-8 weeks after the injury. If an incisor is half knocked out and the dentin has been exposed, if the pulp has not been exposed, a temporary plastic crown lined with zinc oxide clove oil paste can be cemented in place and then filled and treated to restore the shape of the crown after there is sufficient restorative dentin formation (6-8 weeks). Anterior teeth whose pulp has been exposed should undergo root canal therapy followed by crown restoration. Any permanent restoration of the tooth should be done 6-8 weeks after the injury. It is recommended to go to the hospital in time and give targeted treatment or therapy under the guidance of the doctor if the incisor is half knocked out.
