Root Canal Treatment

Root Canal Treatment in Camden, North London


NW1 Dental Care are pleased to offer our patients Root Canal Treatment in Camden, North London.


What is root canal treatment?


Root canal also known as endodontics is required when the nerve or blood supply of the tooth ( the pulp) is infected through decay caused by bacterial invasion or injury. The aim of this treatment is to preserve the tooth for as long as possible.


The pulp is made up of soft tissue that includes blood vessels and nerves, also known as the nerve within the tooth. When the pulp gets infected it leads to pulpitis or inflammation of the pulp and its death (necrosis). This can result in an acute alveolar abscess, which is a very painful condition.


To maintain the tooth, root canal treatment is required to clean out the dead tissue and infection and help protect the tooth by filling the canals to stop the same infection recur.


Treatment involved


The treatment may take from one to three visits.
Vitality test is carried out, Local anaesthetic is used if the pulp is still vital. A rubber dam is applied to isolate the tooth and this also helps with moisture control and prevent further contamination from saliva. The root canals are accessed from a small opening made on the biting surface of the tooth.


NW1 Dental care use the latest flexible titanium rotary files with specialist rotary motors to ensure that the tooth canals are shaped efficiently. Root canal files are only used once so as to minimise cross infection and fracture.


Once located and shaped, the length of the canal is measured using a high tech equipment called an apex locator. This helps reduce the need to take x-rays & unnecessary radiation exposure to patient. The canals are also thoroughly irrigated with anti-bacterial disinfectants to get rid of any residual bacteria.


Finally the root canal is dried with an absorbent paper point and filled and sealed with gutta percha a rubbery material which completely fills the canals to prevent infection from reoccurring. The tooth is then usually filled with a tooth coloured composite and patient is advised to cover the tooth with a crown in the future to prevent the tooth from fracturing. Once a tooth has been root treated the tooth structure becomes weaker and is more prone to fracture.

What Happens After?

Patients might experience some discomfort after the treatment, which usually settles in a few days. Patients can take their usual pain killers to relieve the pain.


Root canal success rate prognosis ranges from 70-90% over 5 years.


However root treated teeth can discolour over time. If the tooth has a small access filling only then we can try to internally bleach the discolouration.


If this does not work or the tooth is severely discoloured then covering the tooth with a tooth coloured veneer or crown is another option. Your dentist will inform you of all the choices available for your specific concern.

What If It Happens Again?

Root canal treatments are usually very successful, however there are a number of reasons why root canal treatment unexpectedly fail, this could either be one of the following:


  • Fractured crown or leaking filling material.
  • Narrow or curved canals not treated during the original procedure.
  • New decay developed
  • Saliva has entered the restorative structure.


Retreatment is usually more complicated than initial root canal treatment as the tooth is usually fully restored with a permanent restoration. This can range from a simple filling to a full crown or as part of a bridge. In addition to this a post may have been placed inside the root prior to a final filling being placed. This creates difficulty because access to the root canals is more difficult.


Additionally the canals will have been filled with root filling material. Therefore this has to be removed before they can be instrumented and cleaned again. All of these obstructions make the process more complicated. However it is still possible to treat.

What If I Don’t Have The Treatment?

If you decide not to have the root retreated. You could alternatively have the tooth taken out. Once the pulp has be destroyed, it will not heal back. Therefore it is not not recommended to leave an infected tooth in the mouth, to avoid further complications.

What About After Care?

Root-treated teeth should be treated the same as any other tooth. Regular dental check-ups are recommended. Oral hygiene is very important. You must brush your teeth twice a day with a fluoride toothpaste combined with dental flossing.
