A broken incisor with half of the nerve exposed requires prompt root canal treatment in the hospital, followed by a dental crown restoration.
A broken incisor with half of the nerve exposed is often caused by an external impact. The pulp is exposed and contaminated by bacteria, and radiographs are also needed to check whether the root of the tooth is damaged. Root canal treatment is needed to remove the infected pulp, but if there is a longitudinal fracture of the root of the tooth, the tooth will need to be extracted.
As the crown is fractured and the tooth tissue is not strong enough, the tooth will need to be restored using a staked crown to restore the normal tooth shape.
Half of the incisor tooth is broken and the pain of the exposed nerve is obvious, so it is recommended to seek medical attention.
