Root Canal Therapy

Also known as Root Canal Therapy, Endodontics is generally the only means of treating a tooth when the inner tissues have become infected. This tissue, called the pulp, contains the nerves and blood vessels that help nourish the tooth. Root canal treatment prevents infection from spreading and helps save the tooth from extraction.

Why do I need endodontic treatment?

The most common cause of pulp damage is severe decay or a fracture that exposes the pulp to bacteria, leading to infection. Other causes can include trauma, a broken filling or occasionally gum disease. The infection in your tooth causes inflammation, pain and sensitivity, especially when biting and chewing. With endodontic treatment, we can remove the cause of the infection, the pulp, saving the tooth and allowing it to function normally again.

What does the treatment involve?



Endodontic treatment can be quite lengthy. Some cases can be completed in a single appointment, but we will usually need to see you two or three times in total.

Initially, we carry out a thorough examination of the affected tooth, taking x-rays to help us identify the extent of the infection. We draw up a bespoke treatment plan, specifically designed with the aim of saving your tooth.



Using precise instruments, and often a microscope to aid accuracy, we enter the tooth, removing the infected pulp. We use local anaesthetic to minimise pain, but you may still feel some discomfort during the procedure. This will be worth it for the relief you will feel in the end though!


On completion

The root canals of your tooth are cleaned, flushing out any remaining bacteria. They are then shaped and filled to prevent any further infection, before being sealed with a permanent filling.

Sometimes, it may be necessary to fit a crown on your treated tooth to rebuild it or improve the colour. Once endodontic treatment is complete, your tooth should function just as your other natural teeth and remain problem free for the long term.

Frequently Asked Questions

  • What are the alternatives to endodontic treatment?

    The alternative to endodontic treatment of an infected tooth is extraction. However, gaps in your smile may cause problems with chewing and don’t look nice. If you decide to fill the gap, the options may be a denture, bridge or implant, all of which cost more than root canal treatment.

  • How long will the treated tooth last?

    With proper restoration and care it can last 10-15 years. Each case is unique and the Endodontist will speak to you about the long term prognosis following your root canal treatment. Many root filled teeth will be crowned but your dentist will advise you of this. Of course, the tooth still needs to be looked after with good oral hygiene at home.

  • Why should I see an Endodontist?

    An Endodontist is an expert in all aspects of root canal treatments. Often they will see the more difficult cases. They usually work with a microscope so that they can see the finest of canals. Your dentist will refer you to see our endodontist, Joe Jubert, if they think this is necessary.

  • Will endodontic treatment be painful?

    Many patients are worried about having endodontic treatment, or try to put it off because they are concerned it will be very painful. It will likely not be as bad as you imagine! We use local anaesthetic to minimise pain and help you feel more at ease. Indeed, many patients report that endodontic treatment is similar to having a standard filling, and the relief once the infection in your tooth has been removed will be enormous.
