Failed Root Canal Treatment in East Finchley

Root canal treatment is usually successful, but sometimes a tooth does not heal or becomes reinfected months or years later. You should seek an assessment if symptoms return. Signs include persistent or recurring pain in the treated tooth, tenderness to touch or biting, new swelling of the gums near the tooth, or a small pimple like bump on the gum. Some failures show no symptoms and are found only on a routine dental X-ray. If you are in the East Finchley area, a quick evaluation with our 3D CBCT scanner can identify the cause.

Retreatment is more complex than the original procedure and requires precision and special equipment. You will have a 60 minute consultation including a 3D CBCT scan to diagnose the exact cause of failure, such as a missed canal or a new infection. The treatment itself, performed under a dental operating microscope, takes about 90 to 120 minutes. We start by carefully removing the existing crown and filling material to access the root canals. Then we clean, reshape, and disinfect the canals to remove the infection source. After that, the canals are refilled and sealed, and a temporary filling is placed. You will then return to your general dentist for a permanent restoration like a new crown. The aim is to clear the infection and preserve your natural tooth.

Root canals can fail for several reasons. Often it stems from complex root anatomy, such as narrow or curved canals that were missed or not fully cleaned during the first treatment. For example, a patient from Muswell Hill had a persistent infection. A CBCT scan showed a tiny extra canal in their molar that had been missed. Retreatment allowed us to clean and seal that canal, solving the problem. Other causes include delaying a crown after the initial treatment, which can let bacteria in, or new decay or a fracture that exposes the filling. Our advanced diagnostic tools help identify the exact cause.

Recovery after retreatment mirrors the first procedure. Expect some tenderness for the first 3 to 5 days, usually manageable with over the counter pain relief. Eat soft foods and avoid chewing on the treated tooth until the tenderness fades and the permanent crown is placed. Keep up good oral hygiene by brushing and flossing gently around the area. We will schedule a follow up to monitor healing. Seek immediate care if you have severe or increasing pain after day four, noticeable swelling that spreads, or a reaction to medication. Call during office hours for any concerns. For emergencies outside these hours, contact 111 or visit the nearest A&E.

While our goal is to save the natural tooth, retreatment is not always the best option. We will discuss alternatives. Apicoectomy or root-end surgery can address infections at the tip of the root and may be recommended when retreatment is not feasible. If the tooth is badly damaged or cannot be restored, extraction may be the most predictable choice. We can then talk about replacement options such as a dental implant or a bridge to restore function and prevent shifting of adjacent teeth.

Retreatment costs more than the initial procedure because it involves complex work and specialized equipment. A final price can be given only after a full assessment and 3D scan, since it depends on the tooth’s position and complexity. During the consultation we provide a clear treatment plan with a transparent, all inclusive fee so there are no surprises. As a private practice, we do not offer NHS treatment. We do accept several private dental plans, including Max Bupa, Denplan, and Cigna. Please bring your insurance details to the appointment so we can help you understand your coverage.

To choose the right option, ask providers detailed questions about this procedure. Whether you meet us or another North London practice, consider asking: Why do you think the first root canal failed? What is the success rate for retreatment on a tooth like mine? Do you use a dental microscope and 3D CBCT scanning for diagnosis and treatment? What are the exact costs for the retreatment and what does that fee cover? What are the risks if I do not proceed with retreatment? What experience do you have with complex retreatments? If retreatment fails, what is the next step?
