Root canal treatment is a good solution for pain relief and avoiding tooth loss. Rest assured, the treatment at Bayswater Dental Clinic is pain-free. The clinic is in central London, W2, with easy access.

A healthy tooth is a vital biological tissue with blood supply and nerves. Within a tooth, there is a chamber that accommodates these, called the pulp chamber. The nerves and the blood vessels come to the pulp through the root of the tooth. If the pulp chamber and the canals within the roots get inflamed as a result of an infection like decay, a severe pain can be experienced.


Root Canal Treatment is needed when the pulp chamber and the canals within the roots of a tooth are irreversibly inflamed due to infection, causing severe pain. The inflammation can be caused by many factors such as infection, otherwise known as tooth decay, fractured and broken tooth, fracture lines due to grinding and trauma of a kind. Tooth decay is one of the most common causes of infected pulp resulting in pain and a need for root canal treatment to save the tooth.


No, It does not need to be a painful procedure. Before any root canal treatment is carried out patient must be well anaesthetised, so they do not feel any discomfort during the procedure. Sometimes, when there is a severe acute pain with a tooth, it may take time to fully anaesthetize the patient and higher doses of local anaesthetic may be needed. Without a doubt, we can get patients fully anaesthetized prior to the carrying out a root canal treatment. Different forms of local anaesthesia are available.


Studies have shown that following the proper procedures as laid down by the experts (British Endodontic Society or American Endodontic Society) there is on average 70-75% chance of success with root canal treatments over 4-5 years. Following the correct procedures for the root canal treatment, the type of materials used, the type of equipment used and the skill of the treatment provider contribute enormously to the success rate.

The success rate in repeat root canal treatments can be slightly less because a well-developed infection can already be present within the tooth and the anatomical structures around the root in the jaw bone. The success rate of a repeat root canal treatment is still around 70% or more.


The alternative option to root canal treatment is an extraction of the tooth. Although on many occasions this may seem a more attractive and quicker option to get rid of pain or infection, it should be considered that extraction is an irreversible process.

Extraction is usually recommended by the dentist when it is not possible to restore the tooth with core and crown after the root canal treatment is completed. If a tooth is beyond repair and is suggested to have extraction, the patient can either accept the gap remaining after extraction or replace the missing tooth with denture, bridge or implant.


The cost of a root canal treatment varies. The factors that influence the cost of a root canal treatment can be listed as:

1- The length of time needed to complete the root canal treatment. The bigger and more canals in a tooth, the more expensive the treatment.

2- The experience and qualifications of the person providing the root canal treatment.

3- The materials and the equipment used for the root canal treatment.

4- The complexity of the root canal treatment.

rating star icon LondonAs always the best treatment; on this occasion a visit to hygienist followed by dental check up. I have been going to Dr. Clarke since 1977 as he takes the greatest care of his dental patients. The work he has done has always been of the highest standard possible and he always offers intelligent solutions. Since moving to Wales I still return to Bayswater for my dental treatment. I did have to have emergency treatment in Wales and the dentist was highly respectful of the work done by Dr Clarke. In fact I think he was in awe!
Can't speak highly enough!

The process of root canal treatment consists of disinfecting the inside of the tooth and the roots and then filling them. It is a very skilled and technically involved process and in order to achieve the best result, the root canal treatment can take time and be completed over a few appointments.

The length of time it takes to complete the root canal treatment is usually around several hours It depends on the tooth, its complexity and time and the number of appointments it takes to finish the root canal treatment.


There are two aspects to this;

1- From patient’s point of view, a good root canal treatment means all to go well and back to normal – being pain-free and able to use and chew with the tooth as usual.

2- From dentist’s point of view, a successful root canal treatment means the patient to be pain-free and the tooth to function normally. This is achieved by:

  • Cleaning the canals well and disinfect.
  • Fill the canals well, close to the end of them.
  • Place a good and stable restoration on the tooth before placing a crown on the tooth for normal use.


There are many situations where a root canal treatment may not possible or advised. Here are some of the more general reasons:

1- When the tooth is not predictably restorable after a root canal treatment is done, it may be necessary to do an assessment first to see if a tooth’s root canal is treated, whether it would be possible to restore and finish the tooth. If a tooth is deemed not restorable or has poor prognosis then an alternative option of extraction may need to be considered.

2- There is no accessibility to the tooth to complete a root canal treatment. This is common usually with wisdom teeth.

3- Size of an infection, its severity and the risks associated with it, justify a fast treatment such as an extraction over a root canal treatment

4- Patient not being able to tolerate a root canal treatment.

rating star icon LondonGreat customer service and well-experienced dental surgeons. I was able to book a Saturday appointment after feeling a large bump on my gum on Monday. There was a longer-than usual wait time the day of the appointment and the receptionist was very accommodating and agreed to call me once the doctor was done. I live very close so went home for 15 minutes, hung my laundry, and got the call to come back.

It turned out I needed a tooth extraction as my last wisdom tooth was starting to break through. The dentist assured me he was a specialist in tooth extractions, and he is! Even the needle full of numbing agent was so fast I could barely feel it. The entire process, from me getting into the chair to them finishing the procedure (including taking x-rays) only took 45 minutes—the epitome of quick and painless at the dentist! They were also very accommodating and provided me OTC anti-inflammatory pills to save me a trip to Boots. I required no antibiotics, healed well, and my stitches fell out on schedule after 10 days. Highly recommend Bayswater Dental. :)

rating star icon LondonOwing to an upbringing in Scotland many years ago (pre Fluoride) and years of travelling as well as an injury to my jaw from a climbing accident, I have had to see well over 20 dentists in the course of my life. I have experience of dentists in several countries and work has included implants as well as other quite complex work. When I visited Dr Vahid at Bayswater, he drew up a comprehensive plan, which included some cosmetic work as I wanted to look my best for my marriage a few months ago. Not only did he explain every stage of the plan but he listened carefully to what I wanted or thought I wanted and adapted accordingly. His cosmetic work was superb and the other work that he did on dentistry that was failing was the best I have ever experienced. He has an engineering background as well as being a very experienced dentist; moreover, he explains extremely well and clearly works to the highest standard. The support staff are also very welcoming and helpful. I would recommend Dr Vahid as highly as possible.
