CBCT Scans for Root Canal Treatment in Finchley Central

A standard dental X-ray shows a flat 2D image. A CBCT scan works like a small CT for the jaw, creating a 3D model of the tooth, its roots, and the surrounding bone. For a root canal, this makes a big difference. It helps us see curved canals, extra nerve pathways, or tiny fractures that a 2D film misses. The British Endodontic Society notes that CBCT can be useful for diagnosing and managing complex endodontic problems. Dr. Ashok Reddy uses this tool to map the tooth’s internal structure before treatment, which improves the chances of success, especially in retreatments where a previous root canal has failed. The scan is quick, taking less than a minute, and is done at our Finchley practice.

You may need a root canal guided by a CBCT scan if you have persistent tooth pain after previous treatment, or if your symptoms are unclear. It helps when a conventional 2D X-ray does not provide a clear diagnosis. We typically recommend CBCT for teeth with suspected cracks or fractures, complex root systems such as molars, or for planning surgical endodontics such as an apicoectomy. Case example one: a Finchley Central patient had lingering pain months after a root canal elsewhere. A standard X-ray showed nothing. The CBCT revealed a tiny fourth canal in the molar. We located and treated the missed canal, and the pain resolved. Case example two: another patient had a suspected cracked tooth. The CBCT showed the exact location and extent of the fracture in 3D, helping us determine that the tooth could not be saved. This spared them a root canal that would likely fail.

The process is straightforward and focused on precision. First you have a 60 minute consultation where we take the CBCT scan to see the tooth clearly. Then we schedule the treatment, which typically lasts 60 to 90 minutes. Dr. Reddy uses the 3D scan as a roadmap while performing the root canal under a dental operating microscope, ensuring every part of the root canal system is cleaned and sealed. The procedure uses local anaesthetic, so you feel pressure but not pain. Afterward, your tooth needs a permanent filling or crown placed by your general dentist to protect it long term. The whole process at our practice aims to be painless and effective.

After the procedure you may feel some tenderness for 2 to 3 days, which you can manage with over the counter painkillers such as ibuprofen. Avoid chewing on the treated tooth until it has a permanent restoration. Eat soft foods for the first few days. Maintain good oral hygiene but be gentle around the treated area. We will provide detailed aftercare instructions tailored to your case. Red flags requiring immediate contact: call our practice at 0203 488 0335 during office hours (Mon Wed Fri 9 to 5, Tue Thu 11 to 7) if you experience severe, increasing pain after day 3, swelling inside or outside your mouth, an allergic reaction to medication, or if your temporary filling comes out. For emergencies outside these hours, call NHS 111 or go to your nearest A&E.

While CBCT offers the highest diagnostic accuracy, there are alternatives. A conventional root canal with 2D X-rays is still effective for many straightforward cases. However, it carries a higher risk of missing complex anatomy, which could lead to treatment failure. The only other option is tooth extraction. This is quicker and cheaper at first, but it leaves a missing tooth and can cause the surrounding teeth to shift, requiring a long-term replacement like a dental implant or a bridge, which adds cost and treatment time. Our approach is always to save the natural tooth whenever possible.

To help you make an informed choice, consider these questions for any dentist whether at our Finchley practice or another clinic: Why is a CBCT scan recommended for my case? What information does the 3D scan provide that a 2D X-ray cannot? What is the extra cost for the CBCT scan, and is it included in the overall treatment fee? How will the scan results change my treatment plan? What are the success rates for this procedure with CBCT versus without it?
