A dentist can perform a root canal using local anesthesia to keep the patient comfortable throughout the procedure. They will create an opening in the tooth’s crown and gain access to the tooth’s root canals, which contain nerves, bacteria, and decay. Infections are removed and the canals are cleaned, medicated, and sealed. The tooth is then restored with a filling or dental crown. https://blognetwork.live/blog/root-canal-therapy-effective-treatment-to-save-natural-tooth
