Laser-Assisted Root Canal Therapy in Finchley

Laser-assisted root canal therapy is not required for every case, but it helps in certain situations. You could be a candidate if your tooth has complex anatomy, such as very narrow or curved canals that are hard to clean with standard instruments. It is also useful for retreatment when the prior procedure failed and thorough disinfection is needed to remove persistent bacteria. A patient from Muswell Hill recently needed a retreatment on a molar; the laser's antibacterial power helped resolve the chronic infection. If you have a severe infection or an abscess, the laser can lower the bacterial load and support faster healing. During your consultation, we will use a 3D CBCT scan to assess the tooth and decide if this approach fits your case.

The process mirrors a conventional root canal but adds a disinfection step. First, you have a 60 minute consultation with a 3D scan to plan the treatment. During the treatment, which usually takes 60 to 90 minutes, the area is numbed with local anaesthetic so you feel no pain. The dentist opens the tooth and cleans the canals under a high magnification dental microscope. Next, a very thin flexible laser fibre is inserted into the cleaned canals. The laser is activated briefly to kill bacteria deep in the tiny channels of the tooth root. Finally, the canals are sealed with a biocompatible material and a temporary filling is placed. You return 2 to 3 weeks later for final restoration, like a crown, to protect the tooth.

After the procedure you can expect mild tenderness and sensitivity for 2 to 4 days. This is normal and manageable with over-the-counter pain relievers such as ibuprofen or paracetamol. Eat soft foods and avoid chewing on the treated tooth until the permanent crown is fitted. Continue brushing and flossing as normal, but be gentle around the treated area. Red flags requiring immediate contact: Call our practice during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7) if you experience severe, throbbing pain that isn’t relieved by medication, significant swelling inside or outside your mouth, a fever above 38°C, or if your temporary filling feels loose or comes out. For genuine emergencies outside these hours, please visit A&E or call 111.

The main alternative is a conventional root canal treatment. This remains the standard with a high success rate and is effective for most cases. It uses instruments and disinfectant solutions without laser energy. The main difference is how disinfection is done. Another option, if you cannot save the tooth or if you decline root canal treatment, is tooth extraction. While that removes the source of infection, it creates a gap that can cause other teeth to shift and affect your bite. The missing tooth would then require replacement with a dental implant or bridge, which takes longer and costs more. We always aim to save the natural tooth where possible and will discuss the pros and cons with you.

To decide what fits you best, ask these questions when you meet with us or another North London practice. Ask what type of laser is used, the main benefit for your case, whether the laser affects the cost, the practitioner's experience with lasers for root canals, any risks, and whether the fee includes the final crown.

Our practice is a private-only clinic, and we do not offer NHS services. The cost for complex root canal treatment reflects the advanced training and technology involved, such as the use of dental operating microscopes and 3D CBCT scanning. The addition of laser disinfection will be discussed during your consultation as part of a complete treatment plan. We believe in full transparency, and you will receive a detailed breakdown of all costs before any treatment begins, with no hidden fees. A patient from Barnet recently required a complex retreatment where the laser was essential; the clear, itemised plan helped them understand the value. We accept several private insurance plans, including Max Bupa, Denplan, and Cigna. Please contact our reception to discuss your coverage.
