Treatment for Persistent Tooth Infection in Finchley Central

A standard root canal is usually successful, but sometimes an infection can linger or return months or even years later. You should seek an assessment at our Finchley practice if you experience any of the following, particularly in a tooth that has already had root canal treatment. Key signs include a dull, persistent ache that never fully disappears, tenderness to touch or bite on the tooth, or a recurring pimple-like bump (a sinus tract) on your gum that may ooze pus. Other indicators are renewed swelling around the tooth or unexplained discoloration. These symptoms suggest the initial treatment has failed or the infection has found a new foothold, requiring a more advanced approach to resolve.

Root canal retreatment is a meticulous process to address the source of a persistent infection. First, we'll conduct a 60-minute consultation, including a 3D CBCT scan to map out the tooth's anatomy and identify hidden canals or complex issues. The retreatment procedure itself typically takes 90-120 minutes under local anaesthetic. We begin by carefully removing the existing crown and filling material to access the root canals again. Next, using a dental operating microscope for high magnification, we thoroughly clean the canals, removing any residual infected tissue and disinfecting the entire system. Finally, we refill and seal the canals with a new biocompatible material and place a temporary filling. You'll then return to your general dentist for a new, permanent crown.

A patient from Finchley Central came to us with a persistent dull ache in a tooth treated over two years ago. Our 3D scan revealed a tiny, missed canal that was harbouring bacteria. Using a microscope, Dr. Reddy was able to locate and clean this fourth canal, and the patient's symptoms resolved completely within a week. Another case involved a referral from a nearby dentist in N3. The patient had a recurring gum boil. Microscopic retreatment allowed us to remove old, leaky filling material and disinfect the canal system properly, which finally cleared the chronic infection.

After retreatment, it's normal to feel some tenderness and sensitivity for 3-5 days as the area heals. This is usually manageable with over-the-counter painkillers like ibuprofen. We advise you to avoid chewing directly on the treated tooth until your permanent crown is fitted. Stick to softer foods for the first few days. Your tooth and gums may feel slightly different, but the acute pain from the infection should be gone. Long-term, maintaining excellent oral hygiene with regular brushing and flossing is key to protecting the tooth. We will schedule a follow-up to ensure everything has healed perfectly. Red flags requiring immediate contact: Call our practice during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7) if you experience severe, throbbing pain that isn't managed by painkillers, significant swelling that spreads to your face, or a fever above 38°C. For emergencies outside these hours, please visit A&E or call NHS 111.

Our primary goal is always to save your natural tooth. However, sometimes retreatment may not be the best course of action. Apicoectomy (Minor Surgical Procedure): If the infection is located at the very tip of the root, we may recommend a minor surgical procedure called an apicoectomy. This involves removing the root tip and sealing it from the end. This is often the next step if conventional retreatment is unsuccessful. Tooth Extraction: In cases where the tooth is severely fractured or has insufficient structure remaining, extraction may be the only predictable option. After extraction, we can discuss replacement with a dental implant, which functions like a natural tooth but is a more involved and costly process.

To make an informed choice about your care, whether with us or another practice in North London, ask these questions: 1. Do you use a dental operating microscope for all retreatment cases? 2. What is your success rate for root canal retreatments like mine? 3. Will a 3D CBCT scan be used to diagnose the problem? 4. What are the signs that the retreatment has been successful? 5. What are the full costs, including diagnosis and the final restoration? 6. If retreatment fails, what is the next step you would recommend? 7. Do you accept private insurance plans like Denplan or Cigna?

As a private practice limited to endodontics, we do not offer NHS treatment. The cost of root canal retreatment is higher than an initial procedure due to its complexity. A definitive quote will be provided after your initial consultation and 3D scan. The fee includes the diagnostic imaging, the procedure itself, and all necessary follow-up appointments. There are no hidden fees. We accept several private insurance plans, including Max Bupa, Denplan, and Cigna. Our team will happily assist you with any necessary paperwork for your insurance provider.
