Treatment for Persistent Tooth Infections in North Finchley

A persistent infection, often in a tooth that has already had root canal treatment, does not always cause strong pain. You should seek an assessment if you notice signs. A small, recurring pimple like bump on your gum near the tooth, a sinus tract, is a classic sign. You might feel a dull ache or pressure when chewing. Sometimes the only sign is the tooth darkening compared with neighbours, or a dentist spots a problem on a routine X-ray. For patients in North Finchley we offer same day appointments during office hours for urgent assessments to diagnose these subtle but serious issues before they worsen.

Root canal retreatment is a precise procedure designed to clear a persistent infection and save the tooth. First, you have a 60 minute consultation where we use a 3D CBCT scan to map the root system and locate the infection’s source. The treatment itself, under local anaesthetic, lasts about 90 to 120 minutes. We reopen the tooth, remove the old filling material, and use a dental operating microscope to locate and clean any hidden or missed canals. This magnification is essential for success. After thorough disinfection, we seal it with a new biocompatible filling. Finally, you return to your general dentist for a crown or permanent restoration to protect the tooth. Case Example: A patient from North Finchley came with a persistent dull ache in a molar treated five years earlier. Our 3D scan showed an untreated fourth canal harbouring bacteria. Using the microscope, the clinician located, cleaned, and sealed this tiny canal, resolving the infection. The patient was pain free within a week.

After retreatment you will likely have tenderness and sensitivity for a few days. Days 1 through 3 peak tenderness. You can manage discomfort with ibuprofen and avoid chewing on the treated tooth. Eat softer foods like pasta, eggs, and yoghurt. Swelling is uncommon; if it occurs, an ice pack helps. In week one and beyond the tooth should feel better each day. It is important to return to your general dentist for the final crown within a few weeks to prevent re infection or fracture. Red flags to call during office hours are severe, throbbing pain not relieved by painkillers, swelling that worsens after day three, or a fever or feeling unwell.

Saving your natural tooth through retreatment is usually the best option because nothing works as well as your own tooth. However consider the alternatives. Root Canal Retreatment has a strong success rate, typically 75 to 90 percent, and preserves your tooth, bite and jawbone. It is the most conservative approach. Apicoectomy is a small surgery to remove the root tip if the infection sits at the tip and seal the canal after retreatment. Extraction is quicker and initially cheaper but leads to bone loss and requires a replacement such as a dental implant or a bridge. In the long term extraction plus replacement often costs more and is more invasive than saving the tooth. Case Example: A client from Whetstone had a persistent infection where retreatment was not feasible due to a fractured root. We explained extraction was the predictable option. We removed the tooth and referred for implant consultation, ensuring the long term plan was understood.

The cost of root canal retreatment is higher than an initial root canal because it is more complex and time consuming. Prices vary depending on which tooth is affected and the complexity of removing old filling materials. During your consultation we provide a transparent fixed quote with no hidden fees. The fee includes the 3D CBCT scan, the full procedure, and all necessary follow up checks. We are a private only practice and do not offer NHS services. However, we do accept patients with private dental insurance from providers including Max Bupa, Denplan, and Cigna. Please bring your insurance details to your appointment so we can assist with any claims.

To make an informed choice about your treatment, here are important questions to ask any provider, whether it is our practice in Finchley or another elsewhere: What is the likely success rate for retreatment in my specific case? Do you use a dental operating microscope and 3D CBCT scanning for all retreatment cases? What are the signs that retreatment has been successful? What happens if the retreatment does not resolve the infection? Is the quoted price inclusive of all appointments and diagnostic scans? What are the risks of leaving the persistent infection untreated?
