3D-Guided Root Canal Retreatment for North Finchley Patients

Root canal treatment has a high success rate, but sometimes an infection persists or returns months or even years later. You should consider retreatment if you notice specific symptoms. These include persistent or returning toothache, new swelling around the tooth, tenderness in the gums, or a small pimple-like bump (an abscess) near the tooth root. Sometimes there are no symptoms, but a problem is spotted on a routine dental x-ray. This often happens because of complex root anatomy, a new cavity that has infected the previous treatment, or a crack in the tooth. If you experience any of these issues in North Finchley, a 3D scan at our Finchley practice can provide a definitive diagnosis.

Our process is designed for precision and comfort. First, you will have a 60-minute consultation where we use our 3D CBCT scanner to get a complete picture of the tooth and surrounding bone. This scan is essential for planning the retreatment. Next, during the treatment appointment, which typically takes 90-120 minutes, Dr. Reddy will work under a high-magnification dental microscope. He will carefully remove the old root filling material, clean and disinfect the canals, and address the source of the failure, such as finding and treating a previously missed canal. Then, the canals are refilled and sealed. Finally, you will return to your general dentist for a permanent crown to protect the tooth. The success rate for 3D-guided retreatment is generally between 80-95%.

After the procedure, it is normal to experience some tenderness and sensitivity for a few days. Here is a typical timeline. In the first 24-72 hours, discomfort can be managed effectively with over-the-counter painkillers like ibuprofen. Stick to a soft food diet and avoid chewing on the treated tooth until the tenderness subsides. You can usually return to normal activities the next day. A recent patient from North Finchley, a teacher, had their retreatment on a Thursday afternoon and was back at work on Friday. In the long term, good oral hygiene is essential to protect the tooth. Red flags requiring immediate contact: Call our practice if you experience severe, increasing pain after day 3, visible swelling that spreads, or a fever above 38°C during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7). For out-of-hours emergencies, visit A&E or call 111.

While retreatment is often the best option to save your tooth, there are alternatives. One option is an apicoectomy, a minor surgical procedure to remove the infected tip of the tooth's root. This is usually considered if retreatment has failed or is not possible. The other main option is tooth extraction. While this removes the problem, it creates a gap. A gap should be filled to prevent other teeth from shifting, and the best way to do this is with a dental implant. An implant is a permanent, strong solution but is more invasive and costly than saving your natural tooth. We aim to preserve your original teeth where possible, in line with our practice philosophy.

As a private practice, we do not offer NHS endodontic treatment. The cost of root canal retreatment is higher than an initial root canal because the procedure is more complex and time-consuming. The final fee depends on which tooth it is and the complexity of the case. During your initial consultation, we will provide a full, transparent breakdown of all costs, including the 3D CBCT scan, with no hidden fees. We accept private dental insurance plans from major providers including Max Bupa, Denplan, and Cigna. Please bring your insurance details to your appointment so we can help you understand your coverage.

To choose what is right for you, it helps to be prepared. Whether you consult with us or another practice in North London, ask these essential questions: * What is the likely success rate for my specific case? * Why did your team believe my first root canal failed? * Do you use a dental microscope and 3D CBCT scanning for all retreatments? * What are the full costs, including the scan and any follow-up visits? * What are your qualifications for performing this complex procedure? (for example MSc in Endodontics) * What are the risks if you choose not to have the retreatment?
