Failed Root Canal with Chronic Abscess. Re-treatment or Abstraction and Implant? (photo)
The 2009 root canal failed due to the ill-fitting crown and I now have a chronic abscess deep in the former root near my sinus. (Gum boil visible in photo). Should I attempt to save the tooth through re-treatment and a new crown or move straight on to abstraction and implant? What is the max amount of time you can go "toothless" before having an implant? Is a year too long?
