Saw dentist and still not sure when it is okay to do nothing for a failed root canal. The condition is assymptomatic.

Saw my dentist, reviewed the literature, etc and I'm still VERY confused. When is an apicoectomy required for a failed root canal that can't be reworked? Extraction is never mentioned as part of the treatment plan.

What criteria are being used to judge if the root canal has failed? Pain? Swelling? How it looks on an x-ray?
It's kind of hard to say more without more information.
