Treatment for Persistent Tooth Infections in East Finchley

You should seek advanced care if a root-treated tooth develops new or recurring symptoms. This warrants attention, as the infection can spread. Key signs that your tooth needs re‑assessment include a dull ache or sharp pain when biting, a pimple-like bump on your gum that may release pus, tenderness or swelling in the gum around the tooth, and sometimes discolouration of the tooth. Many patients come to us from East Finchley because symptoms return months or even years after the initial procedure. These are clear indications that bacteria remain in the root canal system and a more advanced approach is needed.

Stage one is a thorough diagnosis, more detailed than a standard root canal. It begins with a 60-minute consultation using 3D CBCT scanning. This imaging shows the tooth’s root structure in three dimensions, revealing missed canals or cracks invisible on 2D x-rays. After identifying the problem, the retreatment takes about 90 to 120 minutes. Under local anaesthetic and with a high-magnification microscope, Dr. Reddy reopens the tooth, removes the old filling, and thoroughly cleans and disinfects the entire canal system. Finally the canals are sealed with a new sterile filling. The goal is to remove the infection source and give the tooth the best chance to heal.

After retreatment you may feel tenderness and sensitivity for a few days as the area heals. Pain is usually manageable with over the counter medicines such as ibuprofen. Do not chew on the treated tooth until a final crown or filling is placed. A soft food diet is advised for the first 48 to 72 hours. In the long term a retreated tooth with proper care can last a lifetime. The typical success rate is around 75 to 90 percent when you maintain good oral hygiene and a protective crown. Red flags include severe, throbbing pain not controlled by medicines; swelling in or around the mouth that grows after day three; an allergic reaction to medication; or a temporary filling coming out. For emergencies outside office hours call 111 or go to the nearest A and E.

While retreatment often saves the tooth, other options suit some cases. Apicoectomy (Root-End Surgery): if the infection sits near the tip of the root or retreatment is not feasible due to a complex crown and post, we may suggest a minor surgery to remove the root tip and seal the end. It's effective but more invasive than retreatment. Tooth Extraction: if the tooth is badly fractured, decayed, or has little bone support, extraction may be the best option. After extraction you can replace the tooth with a dental implant, bridge, or partial denture to restore function and appearance. We aim to save natural teeth, but we will give an honest assessment of when extraction offers the best long-term result.

To choose wisely, ask these questions: why did my original root canal fail, what is your retreatment success rate, do you use a dental microscope and 3D CBCT for diagnosis and treatment, what are the risks of doing nothing about the persistent infection, is an apicoectomy or extraction a better option in my case and why, what are the total costs including the final crown, and what are your qualifications for this complex procedure.

As a private practice, NHS treatment is not offered here. The retreatment cost is higher than an initial root canal because the procedure is more complex and time consuming. A definite quote is provided after a full assessment, including a 3D CBCT scan, during your first consultation. The fee covers the diagnostic process, the retreatment itself, and all follow-up appointments. We accept various payment methods and work with private dental insurers including Max Bupa, Denplan, and Cigna. Our team provides a transparent breakdown of all costs with no hidden fees.
