Unless you recall as many patients as possible you don't know with any degree of confidence how your work is performing. We recall regularly at 1 year, 5 years and whenever we can after that. This was a 7 year re treatment recall that came to see me for another tooth. We get a lot of people coming back for another tooth as they say they only want me to do any future endodontic treatment that is needed. The images here speak for themselves, are dated automatically by my great software, and show beatiful new bone growth around the roots.
