Root Canal Treatment, also known as endodontics, is a dental procedure carried out by Root Canal Treatment Specialists in London who are trained to treat an infection or irreversible inflammation of the nerve or pulp of a tooth. If left untreated, this may be caused by deep decay, a fracture of the tooth, or severe periodontal disease.

If you need a Root Canal Treatment in London, Smile Cliniq’s very own Dr Krishen Shah has a special interest in Root Canal Treatment with a Masters in Endodontic Practice, who is on hand to perform the most complex Root Canal Treatments with the utmost care and expertise.

An Overview of The Tooth Structure:

A tooth is made up of three parts:

  1. The enamel, which is the hard outer coating of a tooth.
  2. The dentine, a softer, bone-like material that supports the enamel.
  3. The pulp, which is soft tissue (containing nerves and blood vessels) at the centre of the tooth.

What is Root Canal Treatment London?

The pulp has a path that runs down through the inside of the tooth and into the gum and jawbone. This path is known as a root canal. In some cases, a single tooth can have more than one root canal. The term root canal is slightly misleading because it implies that the pulp and the root canal of the tooth are empty. However, the pulp and the root canal are made up of soft tissue that contains nerves and blood vessels.

If the pulp becomes infected by bacteria, it will begin to die, which could result in the loss of the tooth. There is also the risk that the infection could spread down into the root canal, which may lead to the development of a painful dental abscess (a pus-filled swelling). The infection could then spread to your gums (causing a perio-endo lesion) or the tissue and bones that support your teeth (periodontitis).

Root canal treatment is designed to save the tooth and prevent the risk of root canal infection. The inflamed or infected pulp is removed from the tooth and the root canal is then cleaned of all bacteria. After the bacteria have been removed, the root canal and pulp are filled in using an artificial substance, before being sealed. Read our patient testimonials here.

Is Root Canal London Painful?

Root canal treatment is commonly perceived as being a painful procedure. In fact, in the hands of a properly trained dentist, root canal treatment is relatively painless, and it should be no more unpleasant than having a filling done. Smile Cliniq’s Root Canal Treatment in London is in line with best practice techniques using Protaper files, electronic apex locators, and Sodium hypochlorite. If you are worried about root canal pain, we will do our very best to make you comfortable and explain the full procedure to you and other options that might help you.

Root canal treatment is one of the most challenging treatments for a dentist to perform. There are many risks and possible causes of problems when performing a root canal treatment, and accurate measurements, correct instrumentation, and moisture (bacteria) control is vital to ensuring a good result.

The Importance of a Root Canal Dentist in London

Root canal treatment can be very complex and is a time-consuming procedure, and in some difficult cases it is best to see a root canal treatment specialist in London straight away. This is because the success of a root canal treatment being carried out for the first time is much higher than the second time and if it is not done to a high standard, there is a risk of the root canal treatment failing. If this happens, there is a need for a re-root canal treatment. Unfortunately, the success rates of re-root canal treatments are much lower, hence it is important to get it completed correctly the first time.

At Smile Cliniq, we also have a root canal treatment specialist in London Dr Nojan Khalehoghli who has many years of experience and has completed post graduate education solely in endodontics. He is available for a more complex root canal treatment in London.

What is a Root Canal Treatment?

Need a root canal in London? At Smile Cliniq, we make sure that the risk of failure is minimised by using best-practice techniques and high-tech equipment to locate the ends of the roots, ensuring the filling reaches the whole length of the root canal. We have also invested in specially designed fiber optic lights that the dentist may use with their magnifying surgical loupes, for a much clearer and enlarged vision of the very small root canal openings.

We anaesthetize the tooth fully to ensure that the treatment is carried out comfortably, without the much-dreaded root canal pain.

We then isolate the tooth, usually with a rubber dam, to ensure that the field is kept as sterile as possible and that new bacteria contamination of the tooth by saliva is avoided. Maintaining a moisture-free, sterile environment when performing a root canal treatment is important as this prevents any bacteria in the mouth from entering the canals.

Our root canal specialist in London then uses modern flexible titanium Protaper files to ensure that the canals are shaped efficiently. We only use our files once, to minimise the risk of fracture and reduce the risk of cross-infection.

We use high-tech electronic apex locators to establish the length of canals accurately and to reduce the number of radiographs and hence radiographic dosage. We thoroughly clean the canals with powerful disinfectants such as sodium hypochlorite and occasionally iodine to destroy any remaining bacteria inside the canals.

We also use highly specialised equipment when placing the filling material, in certain cases – the hot shot and hot tip from smart endodontics. Our Endodontist in London, Dr Krishen Shah, is fully trained and experienced in using this advanced equipment for the best results.

The HotShot is a cordless backfill obturation device that fills the root canals. The thin and flexible needles provide easy access to even very thin canals, ensuring fuller obturation lowering the risk of re-infection.

The HotTip is a cordless warm vertical compaction device and comes in a variety of sizes to accommodate different sized root canals.

If you’re wondering ‘How long does a root canal take?’ It does vary on a case-by-case basis, but the use of this specialist equipment reduces chair time for the patient and allows the dentist to carry out the treatment smoothly and easily. You may experience some post-operative root canal pain which usually settles down with painkillers.

Root Canal Treatment London FAQs

What is the root canal cost London?

At Smile Cliniq, root canal cost London start from just £250. View our full-price list and the available payment plans for root canal costs here.

What can I eat after having a root canal treatment London?

When you have root canal treatment London, a local anesthetic is used to numb the treated area. It can take up to two hours to wear off, so it is best to have food only after it has worn off.

Once you feel a normal sensation in your mouth, you will still be recovering. Therefore, avoid sticky foods like jelly beans or gum after your root canal treatment London; these can loosen or remove the temporary filling in your tooth. It’s best to eat soft foods that require little chewing; your tooth is likely to be sensitive in the days after your treatment and hard or hot foods can cause irritation. When eating, choose the side of the mouth opposite your treated tooth.

Furthermore, you should maintain a good dental hygiene regime, brushing and flossing as you regularly would to keep the treated tooth free of food particles and bacteria.

How much time off work do I need to recover after having root canal London?

Most of the time, people who have had root canal therapy can go back to work or school the next day. However, if you’ve had sedation during your dental procedure, you may need an extra day or two to fully recover.
