If it is a simple crown fracture, a specific examination of the tooth is needed to see if the fractured surface has reached the pulp, if it has not reached the pulp, resin restoration treatment can be done; if it has reached the pulp, root canal treatment is needed before restoration treatment. If the root is fractured, the tooth may need to be extracted. The fracture of the front teeth is mainly caused by caries and trauma, while the back teeth are mainly related to caries and occlusal trauma. For teeth with caries, the decayed tissue must be removed, and then resin restoration or crown restoration, and porcelain veneer restoration can be done for the front teeth, which can achieve a minimally invasive and aesthetic effect. If the fractured surface of the tooth has destroyed the dental nerve, then root canal treatment is needed before restoration treatment. For teeth with a large fracture surface, which has reached the root of the tooth. The best treatment is to remove the tooth and then restore it with an implant. For the restoration of fractured teeth, it is necessary to take x-rays to check the location of the fracture and to determine the distance between the fracture surface and the pulp, and then to determine the restoration method.
