Laser-Assisted Root Canal Therapy for North Finchley Patients

Laser-assisted root canal treatment is an option to save an infected tooth. It is especially useful when the root anatomy is complex with tiny, hard-to-reach canals that standard instruments may struggle to clean completely. It can also help with retreatment when a previous procedure has failed and thorough disinfection is needed. The British Endodontic Society notes that conventional root canal treatment succeeds in about 85 to 95 percent of cases; using the laser can improve outcomes in these tougher scenarios. If a tooth has a poor prognosis, laser therapy at our Finchley practice may offer a better alternative to extraction.

The process is similar to a conventional root canal, with an extra disinfection step. First you will have a 60-minute consultation that includes a 3D CBCT scan to map the tooth’s root structure. During the treatment, which typically lasts 60 to 90 minutes, we numb the area with local anaesthetic. Dr. Reddy then cleans the infected pulp from the canals using traditional instruments under high magnification. The key difference is a fine, flexible laser tip inserted into the canals. The laser energy removes remaining bacteria deep inside the microscopic tubules of the tooth root, areas that liquid disinfectants cannot always reach. Finally the canals are sealed and a temporary filling is placed. You will return later for a permanent crown to protect the tooth.

A patient from North Finchley came in with ongoing pain from a tooth that had a root canal years earlier. Our 3D scan showed a missed canal and signs of reinfection. We recommended laser-assisted retreatment. The laser’s deep disinfecting power was essential to cleaning out the chronic infection from the entire canal system. The procedure took about 90 minutes, and the patient’s symptoms cleared within a week. The laser gave extra confidence for a successful outcome where conventional methods had failed.

A patient was referred for a severely infected upper molar with curved roots. The laser’s flexible fibre optic tip let us follow the curves and deliver disinfecting energy to the end of the root, ensuring no bacteria remained. This precision, together with our operating microscope, helped save the tooth that might have been extracted. The patient avoided an implant and kept their natural tooth.

After the procedure you may have tenderness for two to three days as the anaesthetic wears off and the area heals. This is usually mild and can be managed with over the counter pain relief. Avoid chewing directly on the treated tooth until the permanent crown is fitted. You can brush and floss normally, but be gentle around the area. It is common to feel a different sensation in the tooth for a while, but this should fade. If you notice severe, persistent pain, swelling that gets worse after a few days, a loose temporary filling, or an allergic reaction to medication, please contact us during office hours.

The main alternative is conventional root canal treatment. This works well for most cases and follows the same process but without the final laser disinfection step. It is the standard of care and highly effective, though complex cases may benefit from laser disinfection. Another option is tooth extraction when the tooth cannot be restored. While removing the infection, this creates a gap that needs a replacement such as a dental implant or bridge. This path can be more costly and time consuming in the long run, which is why we aim to save the natural tooth whenever possible.

To choose what is right for you, consider asking a few questions whether you meet with us or another practice in North London: what specific benefits does the laser offer for my case, what laser do you use and what is its track record for endodontic procedures, is there an extra cost for the laser compared to conventional treatment, how does your experience with laser technology compare to other methods, does the laser change the recovery time or aftercare instructions, and what are the success rates for this procedure in your practice?

The cost of any root canal depends on case complexity and which tooth is affected. Using advanced technology like a dental laser and 3D CBCT scanning is reflected in the fee but supports a high standard of care. After your initial consultation and scan we provide a full treatment plan with a clear breakdown of costs and no hidden fees. Our practice is private, so NHS treatment is not available. We do accept private dental insurance from providers including Max Bupa, Denplan, and Cigna. Please have your policy details ready when you contact us.
