If a tooth is marked for certain removal, tooth transplant can be tried as a treatment. If despite root canal treatment a tooth must be removed, then another, less used tooth (such as a wisdom tooth or an impacted one) can be transferred to the removed tooth’s location. If the operation is successful and the transplanted tooth roots itself, it can be used for life with the proper care.
Considering there are many ways of saving a tooth, it must be stressed again that removal of a natural tooth is always a last resort. While every operation has a risk of complication, the rate of successfully recovering a tooth with these methods is quite high.
