The patient needs to consult a dentist to take dental radiographs to determine whether the tooth can be retained. If the root of the tooth is intact and has therapeutic value, root canal treatment can be carried out, and crown restoration can be carried out to avoid the tooth from splitting if necessary. 2. If the tooth is seriously decayed and cannot be retained, it needs to be extracted under strict sterilization. Large teeth usually have three or four roots, which is more difficult to extract. Moreover, the roots of large teeth are thick and the extraction sockets are deeper, which may cause infection if you extract the teeth by yourself, so it is recommended to extract them in the hospital. Therefore, if a big tooth is rotten and empty, it is preferred to keep the tooth, but if it has to be extracted, you need to go to the hospital, don’t blindly extract it by yourself in order to avoid causing infection.
