Laser vs. Traditional Root Canal in North Finchley

A traditional root canal, a time tested and highly effective method, uses fine dental drills and files to manually remove the infected pulp from inside the tooth. The canals are then cleaned with an antibacterial solution before being filled and sealed. The entire process typically requires one or two appointments, each lasting 60-90 minutes. In contrast, a laser assisted root canal uses a focused beam of light to vaporise infected tissue. This technology can reach microscopic areas that manual files might miss, potentially leading to a more thorough disinfection. While local anaesthetic makes both procedures painless, the laser method is often quieter and involves less vibration, which many patients find more comfortable.

Both traditional and laser assisted root canals have high success rates, with studies showing that a well performed treatment can help a tooth survive for up to 10 years or more. Traditional methods are considered the gold standard, especially for complex cases with extensive damage. Laser technology is seen as a strong supplement, particularly valued for its ability to sterilise the canal system thoroughly, which may reduce the risk of reinfection. The choice often depends on the specific tooth's anatomy; for instance, a molar with multiple curved canals might benefit from the enhanced cleaning power of a laser. The ultimate goal of both is to save the tooth and eliminate the infection, and both are proven to be effective ways to achieve this.

Regardless of the method, the process starts with a 60 minute consultation at our Finchley practice, including digital X-rays or a 3D CBCT scan to assess the infection. Once treatment is agreed, local anaesthetic is administered to completely numb the area. For a traditional procedure, a small opening is created, and fine instruments are used to clean the canals over 60-90 minutes. With laser treatment, a similar opening is made, but a laser is used to remove and disinfect the tissue. After the canals are cleaned, they are filled with a biocompatible material called gutta percha. A temporary filling is placed, and you will return in 2-3 weeks for a permanent restoration, usually a crown, to protect the tooth. The entire process from consultation to final crown takes about 3-4 weeks.

After a traditional root canal, it is normal to feel some tenderness and mild swelling around the treated tooth for 2-3 days as the anaesthetic wears off. This is usually manageable with over the counter painkillers like ibuprofen. You should avoid chewing on the treated side until the permanent crown is fitted. Stick to soft foods like soup, yogurt, and mashed potatoes for the first few days. It is vital to maintain good oral hygiene but be gentle around the sensitive area. Call us during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7) if you experience severe pain that is not controlled by medication, significant swelling, or a fever.

Recovery after a laser assisted root canal tends to be faster and more comfortable. Because the laser is more precise and minimally invasive, there is less trauma to the surrounding tissue, which typically means less post operative swelling and discomfort. Many patients report being able to resume normal activities almost immediately. While some minor tenderness is possible, it may only last a day or so. The same aftercare advice applies: avoid hard foods and contact our practice if you have concerns like increasing pain or fever.

To decide what fits you best, ask any dentist, whether at our practice or another in North Finchley, these key questions. First, ask which method they recommend for your specific case and why, considering the tooth's location and the complexity of its root structure. Inquire about the success rate they have personally observed with each technology. You should also get a clear breakdown of the costs—whether the laser treatment carries a higher price, and whether the quote includes the final crown. Finally, ask about their level of experience; our practice focuses on endodontics, meaning we have postgraduate training specifically in these complex procedures.

At our private practice, a traditional root canal treatment starts from £550 for a front tooth and from £750 for a molar. Because of the cost of the specialised equipment, laser assisted root canal treatment typically costs around 15 to 20 percent more. This price includes the full procedure, from initial consultation and scans to the final filling of the root canals. The cost of the final permanent crown is separate and will be quoted during your consultation. We are a private practice and do not offer NHS treatment, but we do accept patients with Max Bupa, Denplan, and Cigna insurance. We provide a fully itemised treatment plan with no hidden fees.
