Specialist Root Canal Treatment London


‘Root canal’ is a term that often brings with it unwarranted apprehension, largely due to myths about its supposed painfulness.

However, at the Harley Street Academy of Advanced Endodontics in London, we’re committed to changing this narrative.

Our approach to root canal treatment combines decades of experience and the latest advancements in dental technology with a deep understanding of patient care, ensuring a procedure that is not only effective but also comfortably managed.

This blog aims to demystify the process, shedding light on the importance of root canals and the innovative techniques we employ to ensure your comfort and dental health.

What is Root Canal Treatment?

Root canal treatment, or endodontic therapy, is a dental procedure designed to clear infection from the inside of the tooth, thereby saving the tooth and preventing further infection and pain.

(a very basic demonstration)

The need for this treatment arises when the pulp inside the tooth, which contains blood vessels and nerves, becomes infected due to decay, dental injuries, or repeated dental procedures on the tooth.

The goal is to remove the infected pulp, clean and disinfect the inner tooth, then fill and seal it to restore its function and appearance.

Contrary to popular belief, the procedure itself is painless, thanks to modern anaesthesia techniques. A lot of patients mistakenly think that root canals are painful because of the pain preceding the procedure. Infections in the root of your tooth can be very painful until we’ve cleared them using root canal.

At the Endo Academy, we ensure that every root treatment is pain-free by using the latest dental technology and techniques to preserve your natural teeth and maintain your oral health.

Signs You May Need a Root Canal

Understanding the signs that may indicate the need for a root canal is crucial for timely intervention and treatment.

Common symptoms include:

  • Severe toothache when applying pressure or chewing
  • Prolonged sensitivity to hot or cold temperatures, even after the source has been removed
  • Discolouration of the tooth, turning it darker
  • Swelling and tenderness in the nearby gums
  • A persistent or recurring pimple on the gums near the affected tooth

These symptoms can vary in intensity but they all signal that the pulp within the tooth may be infected or inflamed.

Early diagnosis and treatment are key to preventing the spread of infection and preserving the tooth.

If you’re experiencing any of these symptoms, we encourage you to contact us or your general dentist for a consultation as soon as possible.

Our specialists are equipped with the expertise and technology to diagnose and treat your dental needs accurately, ensuring the best possible outcome for your oral health.

Phases of Root Canal Treatment

Root canal treatment at the Endo Academy is a streamlined process designed to save your tooth and eliminate pain with minimal discomfort. Our approach is divided into several key phases, ensuring every step is carried out with the utmost precision and care:

  • Diagnosis and Planning: Every treatment begins with a thorough assessment of your dental health. Using advanced diagnostic tools, we identify the need for a root canal and plan the best course of action tailored to your specific condition.
  • Preparation: Before the procedure starts, we prepare you to ensure comfort throughout the treatment. This includes administering local anaesthesia to numb the area, and anti-anxiety medication if required – ensuring a pain-free and relaxed experience.
  • Treatment: The core of the root canal involves carefully treating the inside of the tooth. Our specialists remove the damaged tissue, clean the inner chambers, and disinfect the area to eliminate any infection. The focus is on preserving as much of your natural tooth structure as possible.
  • Filling and Sealing: After cleaning, the tooth is filled with a biocompatible material to seal it off from future infections. This phase is crucial for stabilising the tooth and preparing it for the final restoration.
  • Restoration: The final phase involves restoring the tooth with a crown or filling. You will often be referred back to your general dentist for this simpler procedure.

Throughout each phase, our team uses the latest technology to enhance the treatment, from detailed imaging for accurate diagnosis to advanced materials for filling and sealing.

Patient Testimonials

The success of our treatments is best reflected in the words of our patients:

“Richard saved my tooth after my dentist had broken his file during a root canal treatment. It was a very difficult procedure and I am very grateful that he patiently and meticulously took the necessary steps to successfully remove the broken file stuck deep in one of the root canals. Moreover, Irene finished the second part of the procedure and she was one of the most professional dentists I have ever met. Won’t do a root canal treatment without Harley Street Irene or Richard any more.” – Patrick
“I wanted to check a root canal I was concerned about. It was actually a great experience! The place seems amazing, with friendly staff and a completely seamless process from start to finish. Dr Selouk was excellent and explained things in such a nice and clear way. I am very impressed and glad to have found this place I–would recommend to anyone. Many thanks!” – Elsie
“Dr Irene is literally a godsend. She did my endodontic treatment with such care and attention. I would recommend anyone with concerns about cost to opt for her. She is the most affordable dentist at the practice but she performed my treatment to the highest standards and I’m so pleased I chose her and had the opportunity to see that cost doesn’t reflect standards or ability within this practice. I previously had David on the higher end of cost and did not feel any loss in my treatment. Thank you so much for your help. Also the reception staff notably Joanne were extremely helpful and supportive when I found myself in the predicament of choosing the most affordable option and also moving appointments. All in all, a fantastic practice. All of the staff are so helpful and really ease your mind at an incredibly anxiety-inducing time.” – Lauren
