Root canal retreatment and extraction of the affected tooth are not absolutely good or bad, there are advantages and disadvantages, and it is recommended to consider the difficulty of root canal retreatment, the patient’s time, the economic situation and other aspects.
1. First of all, the feeling of using one’s own real teeth is definitely better than all kinds of dentures (implant denture, fixed denture and removable denture); however, not all teeth with failed root canal treatment will be successfully retreated, and some highly curved root canals and root canals with foreign objects in them are usually more difficult to retreat.
2. Secondly, for some difficult retreatment, it usually requires auxiliary treatment such as microscope and later crown restoration, which requires more visits and higher cost.
Therefore, it is recommended that patients who have failed root canal treatment should follow the advice of professional physicians and make a comprehensive judgment on whether to choose root canal retreatment or tooth extraction according to their own situation.
