CBCT-Guided Root-End Surgery in Finchley Central

Root-end surgery is not a first-line option. It is usually considered after a conventional root canal has been done but infection remains at the tip of the root. You might need it if a cyst or an anatomical issue, such as a curved root, prevents a standard canal from working fully. It aims to save a tooth that might otherwise require extraction. Dr. Reddy, who holds an MSc in Endodontics, will recommend this only after a thorough assessment that includes a detailed 3D CBCT scan to confirm necessity and likely success.

A 2D dental x-ray shows a flat image and can miss details. A CBCT scan, which we have on-site in Finchley, creates a detailed 3D model of your tooth, jawbone, and nearby nerves and sinuses. This helps in several ways: locating the infection, finding hidden root canals, and planning the approach to avoid nearby structures like the maxillary sinus or major jaw nerves. This detail improves safety and predictability, leading to better long-term results. With modern techniques such as CBCT imaging and operating microscopes, microsurgical apicoectomy has success rates over 90%.

Case from Finchley Central: a persistent low-grade infection on an upper molar after a root canal done elsewhere years ago. A standard x-ray was inconclusive. Our 3D CBCT showed the infection was very close to the sinus lining. The 3D view let us plan removing the infected tissue and sealing the end of the root without perforating the sinus, a risk far lower thanks to the scan. The procedure was successful and the patient’s symptoms disappeared, saving the tooth.

Full procedure designed for comfort. First, a 60-minute consultation including the CBCT scan to plan treatment. The surgical appointment lasts about 60 to 90 minutes. Dr. Reddy numbs the area with local anaesthetic so you feel pressure but no pain. A small gum incision provides access to the root tip, infected tissue is removed, and the end of the root canal is sealed. The gum is sutured back. We use dental operating microscopes for enhanced vision throughout. A follow-up visit 7 to 10 days later checks healing and removes sutures, about 15 minutes.

Recovery is usually straightforward. In the first 24 to 48 hours you may have some swelling and mild discomfort. This is managed with over-the-counter pain relief and by applying an ice pack to the cheek for 20 minutes at a time. Eat soft foods for a few days and avoid chewing at the surgical site. Keep the area clean with gentle rinsing using saltwater; avoid vigorous brushing over the sutures. Most people return to normal activities within a day or two. Red flags requiring a call: contact us during office hours if you have severe increasing pain after day three, persistent bleeding, fever, or significant swelling that does not improve. For emergencies outside these hours, go to A&E or call 111.

While apicoectomy is highly effective, it is not the only option. The main alternatives are: Non-Surgical Retreatment: it may be possible to redo the original root canal from the crown of the tooth. This is often the first choice if possible, as it is less invasive. We will assess whether this option works for you. Tooth Extraction: removing the tooth solves the infection but creates a gap. That gap would need to be restored with an implant, bridge, or denture to prevent shifting and restore function. Our aim is to save natural teeth whenever possible.

To make an informed choice about your care, whether with us or another practice in North London, here are important questions to ask: Do you use a CBCT scanner to plan all root-end surgeries? Do you use a dental operating microscope during the procedure? What is your experience with this surgery and how many do you perform each year? What does the quoted cost include and does it cover the scan, surgery, and follow-up visits? What are the specific risks in my case based on the 3D scan? What is the long-term prognosis for saving this tooth?

Root-end surgery costs vary with complexity and tooth location. This is a highly specialised procedure requiring advanced imaging and equipment, and it represents an investment in saving your natural tooth. You will receive a full cost breakdown at your initial consultation after the CBCT scan and clinical assessment. There are no hidden fees. Our practice is private, so NHS treatment is not available, but we accept private dental insurance from Max Bupa, Denplan, and Cigna. Please have your policy details ready when you contact us.
