Complex Root Canal Therapy in Finchley

You may be referred for complex root canal therapy if your symptoms point to a tougher case. This often applies to teeth that continue to cause pain after a previous root canal, indicating a persistent infection. You might also need this advanced treatment if you have a molar with very fine, curved, or extra canals that are difficult to see without high magnification. Other signs include a large or persistent abscess on the gum, severe toothache that does not respond to painkillers, or a tooth with unique anatomy that requires specialist equipment for a successful outcome. Our goal is to resolve the infection and save your tooth, even when standard treatment falls short.

The process for a complex root canal is precise and focused on a lasting result. First, you will have a consultation that includes a 3D CBCT scan. This gives us a detailed map of your tooth's root structure to guide planning. The treatment itself is performed under local anaesthetic and typically lasts about 90 to 120 minutes. We use a dental operating microscope to see into the narrow canals, ensuring thorough cleaning and shaping. After removing the infected tissue, we disinfect the canals and seal them to prevent bacteria from re-entering. A temporary filling is placed, and you will then return to your general dentist to have a permanent crown fitted. With a microscope, the success rate for these procedures is over 90 percent.

To illustrate the work we do, a North Finchley patient came to us with persistent pain from a molar that had a root canal five years earlier. Our CBCT scan showed a missed fourth canal harbouring bacteria. Using the microscope, we located, cleaned, and sealed this canal, and the pain resolved entirely. Another patient from Golders Green had a lower molar with severely curved roots. A general dentist would see this as risky, but with our specialised tools we navigated the canals and saved a tooth that was thought to be lost.

After treatment you may feel some tenderness for a few days as the area heals. Here is a typical timeline. Days 1 to 3, peak tenderness, with mild to moderate discomfort usually managed with over-the-counter pain relief. Avoid chewing on the treated tooth and stick to soft foods like soup, pasta, or yogurt. Week 1, the tenderness should ease significantly. You can resume normal eating but should be gentle on the tooth until the permanent crown is fitted. Maintain good oral hygiene around the area. If you experience severe, increasing pain after day 3, swelling, an allergic reaction to medication, or if the temporary filling feels loose or falls out, contact us during office hours. For emergencies outside those hours, go to A&E or call 111.

While our aim is to save your natural tooth, there are cases where this may not be the best option. The main alternative to a complex root canal or retreatment is tooth extraction. After extraction, you can replace the tooth with a dental implant and crown or a fixed bridge. An implant is a titanium post that acts as a new tooth root, providing a strong, permanent solution. A bridge uses adjacent teeth as anchors for a false tooth. While effective, these choices are more invasive and costly than saving your own tooth. We will discuss the long-term outlook of your tooth so you can choose between saving it or replacing it.

To decide what suits you, ask detailed questions whether you see us or another practice in the Finchley area. Consider asking: why is my case complex, do you use a dental microscope and 3D CBCT scanning for all complex cases, what is your success rate with retreatments or teeth like mine, who will place the final crown after the root canal is complete, what are the total costs including the consultation, scan, and treatment, what are the risks if I skip this treatment, do you have postgraduate qualifications in endodontics?

The cost of complex root canal therapy varies depending on the tooth and the difficulty of the case. For a molar with multiple canals or a retreatment, it will be more involved than a simpler case. We provide a detailed treatment plan and a clear breakdown of fees after your initial consultation and 3D CBCT scan, ensuring there are no hidden costs. This is a private practice, so NHS treatment is not offered. We accept several private dental insurance plans, including Max Bupa, Denplan, and Cigna. Please tell our team if you have coverage and we can help with the necessary paperwork.
