These are cases demonstrating excellence in root canal treatment. Notice the root canal filling extending through the entire root. Notice many root canals were retreated (redone) because of failed prior treatment. X-rays showing infection have the infection in the bone highlighted (at the end of the root.) Most have recall exams so you can see evidence of the bone healing and regenerating once treatment is completed well. Many of these root canals are examples of retreatments (re-doing previously failing root canals). In these instances, you will see the original deficient treatment (missed canals, broken instruments, roots only partially cleaned, etc.) and then treatment rendered to correct it. These healed cases are NOT isolated or infrequent occurrences as long as it is done properly. For more information on what is necessary for root canal success, visit root canal therapy works. The evidence below disproves the critics because you can see for yourself the jaw bone completely heals and regenerates (contrary to the untruthful claims made by a few. See root canal criticism). And not a single one was altered digitally in ANY way.
