3D-Guided Root Canal Retreatment in Finchley

Retreatment becomes necessary when the initial treatment does not heal or becomes re infected. You should consider this procedure if you have persistent pain, swelling, or a pimple like bump on your gum near a tooth treated before. Sometimes there are no symptoms, but a routine dental X-ray reveals a problem. You are a good candidate if you want to save your natural tooth rather than extract it. The main goal is to resolve infection and pain while keeping the tooth for years. Success rates for retreatment, especially with 3D guidance, are high, often in the 80 to 95 percent range.

Your first visit is a 60 minute consultation. We discuss your symptoms and take a high resolution 3D CBCT scan of the tooth. This scan provides a detailed map of the root canals, showing the cause of the failure. Dr. Reddy, who holds an MSc in Endodontics, will use this to plan the treatment with extreme precision. We explain the findings and share a clear treatment plan.

The retreatment appointment lasts about 90 to 120 minutes. After giving local anaesthetic for comfort, we access the inner part of the tooth. Using a dental operating microscope for magnification, we carefully remove the old filling material, clean the canals, locate any previously untreated anatomy, and disinfect the entire system. In some complex cases, a 3D printed guide helps navigate to a specific area, reducing removal of healthy tooth structure. For example, a patient from North Finchley with a failed molar had a hidden fourth canal. The 3D scan identified it, and a guide allowed us to access it directly, leading to a successful outcome.

After the canals are thoroughly cleaned, we seal them with a biocompatible material and place a temporary filling. You will then be referred back to your general dentist for a permanent restoration, usually a crown, to protect the tooth. We schedule a follow-up review 6 to 12 months later to confirm by X-ray that the area has healed.

After retreatment, it is normal to feel some tenderness and sensitivity for 3 to 5 days as the area heals. This is usually manageable with over the counter painkillers like ibuprofen. Avoid chewing on the treated tooth until the tenderness subsides and the permanent crown is fitted. Stick to a soft diet for the first few days. Maintain good oral hygiene, brushing and flossing as normal but be gentle near the treated tooth. Red flags requiring a call — contact our practice during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7) if you experience severe throbbing pain not relieved by medication, significant swelling that spreads to your face, or a fever. For emergencies outside these hours, visit your nearest A&E or call NHS 111.

While retreatment often saves your tooth, there are alternatives. The main option is tooth extraction. This is quicker and initially less expensive, but it leaves a gap that can cause other teeth to shift. The missing tooth then needs replacement with a dental implant or a bridge, which takes longer and costs more. Another option, if retreatment is not possible, is a minor surgical procedure called an apicoectomy, where the root tip is removed. We discuss the pros and cons of each option based on your clinical situation.

To make an informed choice about your dental health, here are key questions to ask any provider, whether it is us or another practice in North London: What is the success rate for this specific type of retreatment? Do you use 3D CBCT scans and dental microscopes for all retreatments? What are the full costs involved, including the scan and final crown? How much experience do you have with complex retreatment cases? What are the risks if I choose not to have the retreatment? Are there other alternatives for my specific situation?

Root canal retreatment is more complex than an initial root canal, so the price reflects that. Pricing is provided on consultation after a CBCT scan, as it depends on the case complexity and which tooth is affected. As a private practice, NHS services are not offered. We do accept private dental insurance plans from providers like Max Bupa, Denplan, and Cigna. You receive a fully itemised treatment plan with no hidden fees, so you can make an informed decision.
