Laser vs Traditional Root Canal: What's Best in Finchley Central?

A traditional root canal uses fine sterile instruments to clean and shape the tooth's root canals and remove infected pulp tissue. At our Finchley practice, traditional does not mean outdated. We perform this procedure with a high powered dental operating microscope, providing up to 25x magnification, which lets us see and treat even the most complex canal anatomy that would be invisible to the naked eye. We also use 3D CBCT scans for precise diagnosis. This setup gives traditional root canal treatment a strong success rate and remains the proven option for saving a natural tooth. The whole procedure is done under local anaesthetic and typically lasts 60 to 90 minutes.

Laser-assisted root canal uses a specific light wavelength to disinfect the root canal system. The laser energy can kill bacteria and help remove the smear layer created during cleaning. Lasers are usually used as an extra step alongside traditional cleaning rather than a full replacement. No laser shapes the canals on its own. The aim is to reach microscopic side canals that instruments might miss. While encouraging results exist, its long term advantage over microscopic techniques is not yet proven. For example, a recent case from Muswell Hill used a laser after conventional cleaning for final disinfection before sealing the tooth.

The most predictable and scientifically backed method is traditional root canal treatment performed with a dental microscope. Its high success rate is documented over decades. Laser-assisted treatment can help with disinfection, but its long term benefit over microscopic techniques is still being studied. The clinician's skill and the use of magnification are the key factors for success.

Both procedures are done under local anaesthetic, so you do not feel pain during treatment. Some say lasers reduce post operative soreness, but traditional root canal also causes minimal discomfort for a few days. You can expect 2 to 3 days of mild tenderness, which is manageable with over-the-counter painkillers like ibuprofen. We prioritise a painless approach, regardless of the technology used.

A Finchley Central patient had a complex upper molar with four canals, one calcified. A laser alone could not navigate or shape this canal. Using the dental microscope, Dr. Reddy located and cleaned the calcified canal, saving a tooth that might otherwise have been extracted. This shows where the traditional advanced technique is irreplaceable.

To choose what is right for you, whether you see us or another practice in North London, ask these questions: Do you use a dental microscope for all root canal treatments? What is your success rate with your chosen technique? If you use a laser, is it an extra step or the main cleaning method? What does the treatment cost include, such as the 3D scan and the final filling? Based on my 3D scan, what challenges does my tooth show and which technique suits them best?

The cost depends on the tooth's complexity; a front tooth is simpler than a molar. As a private practice, we provide a clear quote after a full consultation and a 3D CBCT scan. This ensures the price reflects the exact treatment you need with no hidden fees. Laser treatment can add a cost, but the biggest factor is the clinician's time and expertise. We accept several private plans, including Max Bupa, Denplan, and Cigna. Let our team know if you have coverage you would like to use.
