After the incisor is broken in half, the first step is to take an x-ray to make sure the root is not broken, and then root canal treatment can be performed. After treatment, a fiber pile is placed in the tooth to restore the basic shape of the tooth, and then the tooth is prepared for a full crown restoration. If the tooth is fractured to a large extent, it is likely that a fiber pile will be difficult to retain and can be used to retain the adjacent tooth. However, it is also true that the adjacent tooth will be damaged because the enamel layer will need to be completely worn away for a crowned restoration. Even after a broken incisor is repaired, it is important not to use the repaired tooth to bite on hard objects, such as gnawing and eating sticky food, which may cause the incisor to fracture.
