Microscope Root Canal Retreatment for Finchley Central Patients

You need retreatment when the first root canal fails to heal or becomes reinfected. This can occur months or years after the original procedure. See us if you have ongoing or returning symptoms like a dull ache, sharp pain when you bite, gum tenderness near the treated tooth, or a pimple-like swelling on the gums. Some failed root canals have no symptoms and are found on a routine x-ray. The main aim is to fix the underlying cause of failure, which often requires equipment not used in general practice.

Root canals can fail for several reasons: tricky anatomy with hidden or curved canals, persistent bacteria, or a new infection from a leaking filling or crown. A dental operating microscope is essential here. It gives up to 25x magnification and bright light, letting the clinician see small details that are invisible to the naked eye. This helps locate hidden canals, remove old filling material completely, and spot cracks or defects that caused the failure. For example, a patient from Finchley Central came to us with a persistent infection. Using the microscope, Dr. Reddy found a tiny fourth canal in a molar that was the source. Without the microscope, that would likely be missed again and the alternative would be extraction.

First you have a 60 minute consultation with a 3D CBCT scan to diagnose the problem clearly. The retreatment itself is a careful procedure done under local anesthesia and usually lasts 90 to 120 minutes. We begin by accessing the root canal, often through the existing crown. Then we use the microscope and ultrasonic tools to remove the old filling material. Next we thoroughly clean, disinfect, and reshape the canals to remove any remaining infection. Finally the canals are filled with a biocompatible material and sealed. You will need a new filling or crown after to protect the tooth, scheduled a few weeks later.

After retreatment you may have some tenderness and sensitivity for three to five days. This is usually mild and can be managed with over the counter painkillers such as ibuprofen. Avoid chewing on the treated tooth until the final restoration is in place. For the first 24 hours eat soft foods. You can resume normal activities the next day but avoid strenuous exercise for 48 hours. Long term success depends on good oral hygiene and placing a final crown to prevent reinfection. Red flags during office hours Mon Wed Fri 9 to 5, Tue Thu 11 to 7: increasing pain after day four, visible swelling in or outside the mouth, or a reaction to your medication. For emergencies outside these hours go to A&E or call 111.

When retreatment is not possible, two main options remain. The first is extracting the tooth. This removes the infection but creates a gap that can cause neighboring teeth to shift. The space can be restored with a dental implant or a bridge, which crowns adjacent teeth. The second option is an apicoectomy, a minor surgery to remove the tip of the root and infected tissue. This is usually only considered if retreatment has failed or is not possible. During your consultation we will explain the pros and cons of each option for your situation.

As a private practice we do not offer NHS treatment. Retreatment is more complex and takes longer than a first procedure. The price reflects the extra work and equipment. We set prices after a full assessment. Your fee covers the 3D CBCT scan, the full retreatment using the operating microscope, and all follow up checks. It does not include the final crown or restoration. We provide a detailed plan with all costs upfront and no hidden fees. We accept private insurance from Max Bupa, Denplan, and Cigna and can help with your claim.

To make an informed choice about your care, whether with us or another practice in North London, ask these essential questions: What is your success rate for root canal retreatment specifically? Do you use a dental operating microscope and a 3D CBCT scanner for all retreatments? What are the specific reasons my first root canal may have failed? What does the quoted price include, and what are the separate costs for the final crown? How much experience do you have with complex cases like mine? What are the risks if I choose not to have the retreatment?
