Failed Root Canal Treatment for West Finchley Patients

Seek an assessment if symptoms return after a root canal. Look for persistent pain that lingers or comes and goes, tenderness when chewing, renewed swelling of the gum, or a small bump on the gum indicating a persistent infection at the root tip. Sudden sensitivity to hot or cold can also signal failure. If you’re in West Finchley and notice these signs, book an urgent assessment to prevent the infection from spreading.

Retreatment is more complex than the first procedure and requires careful planning. First you have a 60 minute consultation with a 3D CBCT scan to identify why the initial treatment failed, such as missed canals, complex anatomy, or new decay. Then the treatment appointment lasts about 90 to 120 minutes with local anaesthetic for comfort. We remove the crown or filling to access the root, and use a dental operating microscope to find and remove the old filling material from the canals. After thoroughly cleaning and disinfecting the canal system, we refill and seal it. A temporary filling goes in and you schedule a return to your general dentist for a new permanent crown.

After retreatment you may feel tenderness for a few days as the area heals. Mild pain is usually managed with over the counter pain relief. Avoid chewing on the treated tooth until the crown is placed. For the first 24 to 48 hours eat soft foods. Swelling may occur but should fade within about 72 hours. Contact us during office hours if you experience severe pain after day three, swelling that spreads, or a fever. Long term, good oral hygiene and regular checkups help the retreatment succeed and keep the tooth healthy.

Non surgical retreatment is often the first choice, but it may not suit every case. An apicoectomy or root end surgery removes the tip of the root to seal it from the end and stop infection directly. This option is usually considered when retreatment cannot proceed or is unlikely to succeed. Its success rate varies, typically around 70 to 95 percent depending on the tooth. Another option is extraction, which removes the infection but creates a gap that needs a replacement such as an implant or bridge. Our aim is to save the natural tooth whenever possible and we will discuss every option with you.

To decide what works best for you, ask any dentist about their experience with complex retreatments and their success rate. Inquire about the technology they use, such as a dental operating microscope and 3D CBCT scanning, which are standard for identifying and treating failed root canals. Request a clear breakdown of costs and whether a new crown is included. Ask what happens if retreatment fails and what the next steps would be. A transparent discussion helps you feel confident about your treatment decision.

Retreatment cost is set case by case, depending on tooth complexity such as whether a crown or post needs removal.
