How is the re-treatment procedure different from the first root canal?
The main difference is that there is already filling material inside your tooth from the first procedure. Our first step is to remove this material.

After that, the process is similar to a standard root canal: we thoroughly clean, disinfect, and seal the tooth to ensure a better outcome.
