CBCT-Guided Root Canal Retreatment for North Finchley Patients

You should consider a retreatment consultation if you experience symptoms of a failed root canal. These signs include persistent or recurring tooth pain that ranges from a dull ache to sharp pain when biting. Some patients notice tenderness or swelling in the gums near the treated tooth, or a small persistent pimple on the gum called a sinus tract. Occasionally a problem is detected on a routine dental X-ray even without symptoms. If you are near North Finchley and notice any of these issues, a prompt assessment is best. The goal of retreatment is to resolve the underlying infection and save your tooth from extraction. Success rates for retreatment are high, often around 80 to 90 percent, especially when planned with precision tools like CBCT.

A CBCT scan is the gold standard for diagnosing and planning complex root canal retreatments. Unlike a flat 2D X-ray, the CBCT scan provides a detailed 3D image of your tooth, roots, and surrounding bone. This is vital for retreatment because it lets us identify the exact cause of failure. For example a recent patient from North Finchley had a persistent low grade infection that a standard X-ray could not explain. Our CBCT scan revealed a tiny missed canal harbouring bacteria. Without the 3D view this would have been hard to find. The scan helps us locate missed canals, visualise complex root shapes, diagnose fractures, and assess the extent of infection, all before we start the procedure. This detailed pre planning greatly improves the chances of a successful outcome.

The process is meticulous and patient focused. First you have a 60 minute consultation where we discuss your symptoms and take a CBCT scan, which takes about 20 to 30 seconds. Next, during a 90 to 120 minute appointment, the procedure is performed under a dental operating microscope for maximum precision. We numb the tooth fully, then carefully remove the old filling material, disinfect the entire canal system using the CBCT plan as our guide, and seal it with a new, biocompatible material. Another patient with a very curved root benefited from this approach; the 3D plan allowed us to navigate the anatomy safely. Finally you will need a follow up appointment in about 6 to 12 months to monitor healing. The entire process aims to be comfortable and effective.

Post treatment care is straightforward. For the first 24 to 72 hours you may feel some tenderness and sensitivity, which is typically manageable with over the counter painkillers like ibuprofen. Avoid chewing on the treated tooth until a permanent restoration such as a crown is placed by your general dentist. Stick to softer foods for a few days. You can brush and floss as normal, just be gentle around the area. Long term, caring for the tooth follows standard guidelines: maintain good oral hygiene and attend regular check ups. Red flags requiring immediate contact include severe throbbing pain not relieved by painkillers, significant swelling inside or outside the mouth, or a fever. For out of hours emergencies, visit your local A and E or call NHS 111.

While our main goal is always to save your natural tooth, there is an alternative if retreatment is not viable or desired. The primary option is tooth extraction. After extraction the missing tooth should be replaced to prevent teeth from shifting and to restore function. The most common replacement options are a dental implant or a fixed bridge. A dental implant is a titanium post that replaces the tooth root, providing a strong foundation for a crown. A bridge uses the adjacent teeth as anchors for a false tooth. During your consultation we will give an honest assessment and discuss the pros and cons of each option for your situation, including long term costs and impact on oral health.

To make an informed choice about your dental health, you should ask the right questions whether you see us or another practice in the North London area. Consider asking: - Do you use a dental microscope and CBCT scanning for all retreatments? - What is your success rate with procedures like mine? - What are the full costs involved, including the scan and any follow up visits? - Why do you believe my original treatment failed? - What are the risks if I choose not to have the retreatment done? - Who will place the final crown after the retreatment is complete? - What specific training do you have in complex endodontics?

Root canal retreatment is a complex procedure and the cost reflects the advanced technology and time required. As a fully private practice we do not offer NHS services. The cost for retreatment will be quoted after your initial consultation and CBCT scan, as it depends on the complexity of the case and the tooth involved. The fee includes the 3D scan, the procedure itself performed under a microscope, and all necessary follow up checks at our practice. We believe in full transparency with no hidden fees. We accept several private dental insurance plans including Max Bupa, Denplan, and Cigna. Please have your policy details available so our team can help you understand your coverage.
