Treatment for Root Canal Complications in Finchley

Discomfort right after a root canal can be normal, but signals long after treatment point to a problem. Seek assessment if pain persists beyond a week or if new pain appears months or years later. Red flags include swelling around the tooth or in the gums, a small pimple like bump on the gum near the treated tooth, or renewed sensitivity to hot and cold. Sometimes there are no symptoms and a problem shows up on a routine dental X-ray. At our Finchley practice we use a 3D CBCT scan for a detailed view, which can reveal missed canals or tiny fractures that standard X-rays miss.

Molars can have complex root systems with four or more canals. If a tiny canal is missed during the initial treatment, bacteria can stay and cause reinfection. Using a dental operating microscope with up to 25x magnification, Dr. Reddy can locate and clean these hidden canals that are often invisible to the naked eye. For instance, a patient from Muswell Hill came to us with lingering pain. Our CBCT scan showed a fourth untreated canal in an upper molar. We retreated the tooth in a single 90‑minute visit, resolving the discomfort completely.

If the final restoration on top of the root canal does not seal the tooth properly, bacteria from your saliva can leak back in and reinfect the root system. The treatment involves removing the crown and old root filling material, thoroughly disinfecting the entire canal system, and then placing a new, well sealed root filling and restoration. We ensure the tooth is properly sealed to prevent future problems.

A vertical root fracture is a crack that runs along the length of the root. This complication often means the tooth cannot be saved and will require extraction. A 3D CBCT scan is the most reliable way to diagnose these fractures. If a fracture is confirmed, we discuss options such as replacing the tooth with a dental implant.

First you have a 60‑minute consultation with advanced imaging to determine the cause. Then, during the treatment appointment (typically 90 to 120 minutes), we numb the tooth completely. We carefully remove the existing crown or filling to access the root canals. The old filling material is removed, and under the microscope we clean, shape, and disinfect the canals again. Once we are sure the infection is gone, we refill and seal the canals. A temporary filling is placed, and you return to your general dentist for a permanent crown to protect the tooth. The process focuses on a painless experience.

The tooth and surrounding gum tissue can feel sensitive for a few days after retreatment. This is normal and usually managed with over‑the‑counter pain relief such as ibuprofen. Avoid chewing on the treated tooth until you get the permanent restoration. You can brush and floss normally, just be gentle around the area. With good oral care, a successfully retreated tooth can last a lifetime. Red flags requiring immediate contact include severe, increasing pain after day four, visible swelling inside or outside your mouth, an allergic reaction to medication, or a loose temporary filling during office hours (Mon/Wed/Fri 9–5, Tue/Thu 11–7). For emergencies outside hours, call 111.

Our primary aim is to save your natural tooth, but retreatment is not always the best option. An alternative is an apicoectomy, a minor surgical procedure where the tip of the root is removed and sealed to resolve a persistent infection. This option comes into play if retreatment has already failed or is not feasible. The other option is tooth extraction, which should be followed by a replacement to stop teeth nearby from shifting. A dental implant is the most durable replacement, though a bridge remains an option.

To choose your care wisely, ask these questions when you talk with us or another practice in North London. What caused the complication? Do you use a dental microscope and 3D CBCT scanning for diagnosis and treatment? What is the success rate for this type of retreatment? What are the total costs, including the final crown? What experience do you have with complex cases like mine? What are the risks if I choose not to have the treatment? Are there alternatives for my situation?

Treating a root canal complication is more complex than the initial treatment, and the cost reflects this. The final fee depends on the tooth's complexity and the treatment required. You will receive a full, personalised quote after your initial consultation and 3D scan. There are no hidden fees. As a private practice, NHS treatment is not offered. We do accept plans from major dental insurers including Denplan, Cigna, and Max Bupa. Please bring your insurance details to your appointment so we can clarify coverage.
