Advanced Laser-Assisted Root Canal Treatment in Finchley

Laser-assisted root canal treatment is not a replacement for the standard method but an improvement. After removing infected tissue with traditional tools, a thin flexible laser fibre is placed in the canals. The laser energy targets bacteria hidden in tiny tubules where instruments cannot reach. This process, known as photoacoustic shockwave disinfection, sterilises the tooth from inside out. For a molar with curved roots, the laser can reach areas hard to clean with conventional methods. We use it alongside our dental operating microscopes and 3D CBCT scans to ensure high precision. Modern endodontics reports success rates above 90 percent, and this technology helps support that by creating a cleaner environment for healing.

Consider a consultation if you have signs of tooth infection such as a severe, persistent toothache, lingering sensitivity to hot or cold, or gum swelling. A laser approach is particularly helpful in certain cases. If you need retreatment after a failed previous procedure, the laser helps disinfect the canal system from stubborn bacteria. A patient from Muswell Hill recently needed retreatment on a front tooth; the laser helped clear the old infection and saved the tooth. It also suits teeth with very complex or narrow root canal anatomy, as the laser energy reaches these small spaces effectively.

Your treatment is planned for comfort and effectiveness. First, you have a 60-minute consultation with a 3D CBCT scan to map your tooth’s internal anatomy. The treatment itself lasts 60 to 90 minutes in one visit. We start with local anaesthetic to numb the area. Under a high-magnification microscope we access and clean the main root canals. Then the laser fibre is used for about 2 to 3 minutes to disinfect the entire system. Finally the canals are sealed with a biocompatible material and a temporary filling is placed. You will return to your general dentist for a permanent crown a few weeks later to protect the tooth long term.

Recovery is usually straightforward. For the first 1 to 3 days expect mild to moderate tenderness, which you can manage with standard pain relief such as ibuprofen. Eat soft foods and avoid chewing directly on the treated tooth until the crown is fitted. You may brush and floss as normal but be gentle around the area. In the long term, care for the tooth as you would any other with good brushing, flossing, and regular check-ups. Red flags requiring immediate contact: Call our practice if you experience severe, increasing pain after day three, swelling that spreads to your face, a fever above 38 C, or if your temporary filling feels loose or comes out during our office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7). For emergencies outside these hours, visit your nearest A&E or call NHS 111 for advice.

The main alternative is a conventional root canal performed to the same high standard with a microscope but without the final laser disinfection step. This remains an excellent option with a strong success rate. The choice depends on the clinical situation. For straightforward cases the laser may offer a small benefit, but in complex retreatments its value increases significantly. The only other option is tooth extraction. While quicker and cheaper upfront, it leads to bone loss and shifting of adjacent teeth. Replacing the missing tooth with an implant is a substantial long term expense, starting from a penny around £2,500, making saving your natural tooth with root canal treatment the preferred and more conservative option whenever possible.

The cost of root canal treatment depends on the complexity and location of the tooth. Molars cost more than front teeth. The use of advanced technology like the dental laser and CBCT scanning is included in our overall fee, ensuring you receive good care with no hidden charges. After your initial consultation and 3D scan, we provide a fully itemised treatment plan and quote. As a private practice, NHS services are not offered. We accept several major dental insurance plans, including Max Bupa, Denplan, and Cigna. Please bring your insurance details to your consultation so we can help with paperwork.

To help you decide about your care, whether with us or another practice in North London, here are important questions to ask: What specific benefits does the laser offer for my tooth? Does your fee cover the laser or is it extra? What type of laser do you use and what training do you have? Do you also use a dental microscope and 3D scanning for every case? What is the long term success rate you see with this technology? What are the costs for the root canal and the final crown restoration?
