I’m worried because my previous root canal has started hurting again and I’m not sure what it means. The tooth feels uncomfortable and I’m scared the treatment might have failed. So my main question is: Can a failed root canal actually be treated again or do I need to remove the tooth?
Yes — a failed root canal can almost always be retreated and in many cases, the tooth can still be saved. When symptoms return (such as pain, swelling or sensitivity), it usually means bacteria have re-entered the tooth due to hidden canals, incomplete cleaning or new decay. At Ashford Dental Centre, their experienced team uses advanced imaging and modern endodontic techniques to carefully reopen the tooth, remove any remaining infection, disinfect the canals thoroughly and seal them properly. Many patients regain full function and comfort after retreatment, avoiding extraction altogether. Early evaluation is important, so if you’re experiencing recurring symptoms, visiting Ashford Dental Centre promptly gives you the best chance to preserve your natural tooth safely and comfortably.
