Root Canal Gone Bad After 11 Years; Implant?

Sometimes the failed endo could be retreated.  An endodontist could provide his/ her opinion on the prognosis of the tooth over the next 5-10 years. 

you have to remember that Implants are not without problems either.  They could develop bone loss, infection.  So it is always better to have your own tooth "saved".

you can always get and implant in the future. 

In this case, if the root canal specialist already gave you the hopeless prognosis of this tooth, then better to take care of this site ASAP.  Have the tooth extracted, site bone grafted, and then implant placed.  The existing infection could resorb the bone further, and make implant treatment more difficult and costly.

There are times that a root canal can be retreated, however if an endodontist told you that it would not be successful I would opt for the extraction.  Have the area bone grafted at the time of the extraction.  Once the area has completely healed the dental implant can be placed.  Good luck.

Root Canal Treatment is 90-95% successful.  A failed root canal can be retreated (lower success rate) or an apicoectomy (cut tip of root off) can be done.  

 

Sometimes there is a perforation (hole) of the root or a vertical fracture which are unlikely to have successful retreatment.of the root canal therapy
