Laser vs. Traditional Root Canal: A Guide for East Finchley

Traditional root canal treatment is highly predictable and effective, with success rates around 85 to 95 percent. It uses fine sterile files to clean and shape the inside of the tooth’s root canals. We use a dental operating microscope for better vision and 3D CBCT scans for precise diagnosis. The goal is to remove all infected pulp tissue, bacteria, and debris. Antibacterial solutions irrigate and disinfect the canals before they are sealed with a biocompatible material. This time tested method stops infection and pain and preserves a tooth that might otherwise be removed.

Laser root canal treatment is not a replacement for the traditional method; it is an enhancement. After the canals have been cleaned and shaped with files, a dental laser is used as a final disinfection step. The laser energy can reach deeper into tiny tubules of the tooth’s root than liquid irrigants alone, potentially reducing remaining bacteria. Proponents say this can lessen post operative discomfort and improve sterilisation. However, it is an extra step in the process, and long term results are still on a par with the high standard set by traditional techniques.

The main difference lies in the disinfection stage. Traditional treatment relies on mechanical cleaning with files and chemical irrigation. Laser assisted treatment adds a final step of thermal disinfection using light energy. While some studies suggest lasers can reduce bacteria more effectively, a well executed traditional root canal remains highly successful. There is often no big difference in treatment time, as the laser portion is brief. However, because it uses specialised equipment, laser assisted treatment may come with a higher cost. Recovery for both procedures is very similar, with mild tenderness typically managed with over the counter painkillers for a few days.

Regardless of the technique used, root canal treatment is needed when the soft tissue inside your tooth, known as the pulp, becomes infected or inflamed. This happens from deep decay, a cracked tooth, or trauma. Seek an assessment if you have severe, lingering toothache, prolonged sensitivity to hot or cold, tooth discolouration, or swelling in the nearby gums. Our practice in East Finchley offers same day emergency appointments during office hours to diagnose the problem and relieve your pain promptly. An untreated infection can lead to an abscess and tooth loss, so early intervention is vital.

First you will have a 60 minute consultation including a 3D scan to plan the treatment. The procedure itself, lasting 60 to 90 minutes, is performed under local anaesthetic so you won’t feel pain. A small protective sheet is placed over the tooth. We then create an opening to access the infected pulp, which is removed. Next the canals are cleaned and shaped with fine instruments. This is where the methods differ: in a laser assisted procedure, the laser is used at this point for final disinfection. Finally the cleaned canals are filled and sealed. A temporary filling is placed, and you return in 2 to 3 weeks for the permanent restoration.

Recovery is usually straightforward. For the first 24 to 48 hours you may feel mild tenderness or sensitivity, which can be managed with ibuprofen or paracetamol. Avoid chewing on the treated tooth until it is permanently restored. Stick to a soft diet for a day or two. Maintain good oral hygiene. Red flags requiring immediate contact: call our practice on 0203 488 0335 during office hours (Mon/Wed/Fri 9 5, Tue/Thu 11 7) if you experience severe, increasing pain after day 3, visible swelling inside or outside your mouth, or a fever. For out of hours emergencies, visit A&E or call 111.

The only true alternative to root canal treatment is tooth extraction. While this may seem easier, we aim to save natural teeth whenever possible. Losing a tooth can cause adjacent teeth to shift and the bone to change. If extraction is needed, the missing tooth should be replaced to maintain function. Replacement options include a dental implant, which is a permanent solution starting from £2,500 plus crown, a fixed bridge, or a removable partial denture. During your consultation, Dr. Reddy will discuss all viable options for your situation.

To choose what fits you, whether you consult with us or another practice in North London, ask these essential questions: Based on your specific tooth, do you believe a laser would provide a significant clinical advantage? What is the success rate of your traditional root canal treatments? Is there an additional cost for using the laser, and what is it? What are the risks and benefits of each option for my case? Do you use a dental microscope and 3D scanning for all root canal procedures? What are my options if this treatment fails?
