Laser-Assisted Root Canal Treatment in East Finchley

You need advanced endodontic care for a severe or persistent tooth infection. This option suits teeth with complex root structures where bacteria hide in tiny spaces. We also treat patients from across North London who have had a previous root canal fail and require retreatment. Key signs include a severe, throbbing toothache, a pimple-like bump (abscess) on the gum, extreme sensitivity to hot or cold temperatures that lingers, or darkening of a tooth. If you experience these symptoms, a consultation at our Finchley practice helps determine the best course of action.

A dental laser is not a replacement for the main root canal procedure; it serves as a powerful aid. After the infected pulp is removed, the laser’s energy helps kill bacteria deep inside the canal and in tiny connecting tubules that traditional files can miss. This process, known as laser activated irrigation, can lower the bacterial load and support healing. Research shows certain lasers are effective at disinfecting the root canal system. For example, a patient from Muswell Hill with a stubborn infection after a prior root canal benefited from adding laser cleaning to the plan, with the 3D CBCT scan confirming a complex canal system. The laser helped achieve thorough disinfection and improved the tooth’s chance of long term survival for another case from Highgate with a challenging front tooth.

The procedure closely mirrors a conventional root canal with an added disinfection step. A 60 minute consultation with a 3D CBCT scan maps your tooth’s root structure. The treatment itself lasts about 60 to 90 minutes and is performed under local anaesthetic so you do not feel pain. The dentist accesses the tooth and removes the infected pulp using fine instruments, all under high magnification from a dental operating microscope. The laser fibre is then inserted into the cleaned canal to activate the disinfectants and eliminate remaining bacteria. The canals are sealed with a biocompatible material and a temporary filling is placed. You return to your general dentist for a permanent crown a few weeks later.

The tooth and surrounding gum may feel tender for a few days as part of healing. This is typically managed with over the counter pain relief. Avoid chewing on the treated tooth until the permanent crown is placed, and stick to soft foods for the first 2 to 3 days. You can brush and floss normally, keeping the area gentle. Because laser disinfection is thorough, many patients report less post operative discomfort compared with conventional methods. Red flags requiring immediate contact: reach out if you experience severe, increasing pain after day 3, swelling that spreads to the face, a fever above 38 C, or if the temporary filling comes out during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7). For emergencies after hours, call 111 or visit your nearest A&E.

The main alternative is a highly proficient conventional root canal treatment performed under a microscope, which already has a high success rate of 85 to 95 percent. Our practice focuses on saving natural teeth, so this remains the gold standard. The other option is tooth extraction. While that removes the infection, it can lead to bone loss and requires a replacement such as a dental implant or bridge, which involves more surgery and higher long term costs. We always aim to preserve your natural tooth structure first.

The cost of laser assisted root canal treatment depends on the case complexity and which tooth is treated. You receive a full personalised quote during the initial consultation after a 3D scan and thorough assessment. There are no hidden fees. We are a private practice and do not offer NHS services, but we accept private dental insurance from providers including Max Bupa, Denplan, and Cigna. Please bring insurance details to the appointment so we can assist with paperwork.
