Expert Treatment for Failed Root Canals in Finchley

A root canal that originally succeeded can still have trouble months or years later. Seek an assessment if you notice lasting pain after the procedure, tenderness when you bite, or new swelling around the treated tooth. A small bump on the gum that may drain pus, known as a sinus tract, can also appear. Sometimes an infection is found on routine X-rays with no obvious symptoms. Causes can include complex root anatomy with missed canals, new decay letting bacteria in, or a faulty crown or filling.

Retreatment is a precise process to clear infection and save the tooth. At the 60 minute consultation, we start with a 3D CBCT scan to map the root canal system. The procedure itself lasts about 90 to 120 minutes and is done under local anesthesia. Dr. Reddy will remove the crown and filling to access the tooth, then use a dental operating microscope to locate and clean all canals. Infected tissue is removed, the canals are disinfected, and a new filling is placed. A temporary filling goes in until the permanent crown is fitted to protect the tooth. The aim is to fully eradicate the infection and create a durable seal to prevent future problems.

A patient from North Finchley came with dull, persistent pain six months after treatment elsewhere. A standard X-ray did not reveal the issue. A 3D CBCT scan found a tiny fourth canal that was missed and harbored bacteria. Dr. Reddy performed a non surgical retreatment, located and cleaned the missed canal under the microscope, and resealed the tooth. The patient’s pain resolved within a week, and the tooth was saved.

After retreatment you may feel some tenderness for a few days. This is usually mild and can be managed with standard pain relief. Avoid chewing on the treated tooth until the crown is placed and stick to a soft diet for a few days. Keep up your normal brushing and flossing around the area, and return to normal activities the next day. If you notice severe pain, swelling, or fever, call the practice during office hours. For emergencies outside those hours, contact the appropriate urgent care services.

Non surgical retreatment is often the first choice but not the only option. We will discuss the best approach for your case. Apicoectomy or root end surgery may be recommended if infection remains at the root end or retreatment is not possible. This procedure removes the root tip and seals the end. If the tooth cannot be saved, extraction may be the most predictable option, followed by replacement with an implant or a bridge.

To make an informed choice about your dental health, here are important questions to ask any provider in the Finchley area: What is the likely success rate for retreatment in my case? Do you use a dental operating microscope and 3D CBCT scanning for diagnosis and treatment? What signs show retreatment has been successful? What are the total costs, including consultation, treatment, and final crown? If retreatment isn’t successful, what is the next step and the cost? What experience do you have with complex retreatments like mine?
