Root canal is done to remove the bacteria from the root canal of the infected tooth so that it can be protected from further decaying. In a root canal, the root of the infected tooth is opened, the infected pulp is removed and the bacteria are cleaned. After that, the filling is done and the cap is placed to seal the filling. The treatment is done with the automated RCT which completes the process in single sitting and without any pain. In this process, Automated RCT is used instead of manual devices which clean the tooth root without damaging the roots.
