The so-called incisor cavity is actually a front tooth decay, which is generally recommended to be treated early and not recommended to be extracted. The earlier it is found, the better the treatment effect will be. Generally, if the bad area of anterior teeth is relatively small, a good aesthetic effect can be achieved by resin filling; if the pulp and nerve are injured, after root canal treatment, generally consider doing restoration protection such as all-ceramic crown. Because the pulp angle of anterior teeth is generally higher, the delay time is too long and it is easy to cause the pulp to be exposed, which is the leakage of nerve, once the leakage of nerve, the anterior teeth will be discolored after the root canal treatment, so once the anterior teeth are found to be decayed, go to the hospital as soon as possible, and through resin filling can achieve a good aesthetic effect. If the nerve is injured and irreversible, it is recommended to repair the tooth with all-ceramic crown after root canal treatment to protect the tooth.
