Advanced Laser Root Canal Retreatment in Finchley

Root canal retreatment is needed when a previous treatment fails to heal or becomes reinfected. A dental laser helps, especially in complex cases. Book a consultation if you have a root treated tooth with symptoms like persistent toothache, tenderness when biting, a pimple-like swelling on your gum (an abscess), or tooth discoloration. Sometimes problems show on a dental x ray with no obvious symptoms. This treatment often suits cases involving a complex root structure with tiny extra canals that were missed, or when new decay allows bacteria to re-enter.

The process is precise and aims to eliminate infection to save your tooth. You begin with a 60 minute consultation using our 3D CBCT scanner to view the tooth's root structure and identify the problem. The retreatment itself takes place in one or two appointments, each lasting 90 to 120 minutes. We numb the tooth fully before reopening it to remove the previous filling material. The dental operating microscope helps locate and clean all the canals. A specialised laser then eliminates bacteria deep in the canal system, reaching areas traditional instruments miss. Finally we seal the cleaned canals with a new biocompatible filling and place a temporary filling. You return to your general dentist for a permanent restoration like a crown.

Traditional retreatment works, but a dental laser offers clear advantages in difficult cases. The laser energy penetrates deep into tiny tubules branching from the main root canal, killing bacteria rinsing solutions might miss. This leads to higher disinfection and lowers the risk of future failure. For our patients, this often means a more predictable outcome. A North Finchley patient with a persistent infection on a molar treated years ago benefited from the laser; the 3D scan showed a missed canal and the laser disinfected the entire system, saving a tooth thought lost. The success rate for non surgical retreatment stays high, around 70 to 90 percent, and enhanced disinfection aims to improve this.

After the appointment you may feel tenderness for a few days as the area heals. This is usually mild and over the counter painkillers like ibuprofen help. Avoid chewing on the treated tooth until a permanent crown is in place. You may brush and floss as normal but be gentle around the area for 24 to 48 hours. One patient from East Finchley found soft foods like soup and yoghurt helped recovery. Red flags for immediate contact: call our practice if you have severe, increasing pain after day three, significant swelling inside or outside your mouth, or fever above 38 C during office hours. For out of hours emergencies, visit A and E or call NHS 111.

There are alternatives to retreatment. Apicoectomy, a minor surgery, removes the root tip and seals it when the infection sits at the end of the root. This option is more invasive but can work when retreatment is not feasible. Extraction and replacement involves removing the tooth and replacing it with a dental implant, a fixed bridge, or a partial denture. Implants provide a durable solution but require losing the natural tooth, cost more, and take longer. We aim to save natural teeth whenever possible.

To help you make an informed choice about your dental health, consider asking any dentist about the Finchley clinic or another. Why did the original root canal fail? What are the benefits of using a laser for this case compared to traditional retreatment? What is the doctor’s experience with this procedure? What is the estimated success rate for my tooth? What are the full costs, including the 3D scan and all appointments? What happens if the retreatment does not work? Will I need a new crown afterward, and is that included in the cost?

Laser-assisted root canal retreatment is a private dental treatment and is not available on the NHS. The cost reflects the procedure's complexity, the advanced technology used, and the clinical time required. Prices follow a full clinical assessment with our 3D CBCT scanner, but typically range from £900 to £1,500 depending on the tooth and the difficulty of the case. This fee includes the consultation, scans, and the retreatment procedure itself, with no hidden fees. It does not include the final permanent crown or filling, which you obtain from your regular dentist. We accept private dental insurance from providers including Max Bupa, Denplan, and Cigna, and can supply the necessary documentation for your claim.
