Endodontics (Root Canal Treatment)

Root canal treatment, also known as endodontics, is a dental procedure designed to treat infection or decay that has occurred at the centre of the tooth.

The structure of the tooth

A tooth is made up of three parts:

  • the enamel, which is the hard outer coating of a tooth
  • the dentin, a softer, bone-like material that supports the enamel, and
  • the pulp, which is soft tissue at the centre of the tooth

The root canal

The pulp has a path that runs down through the inside of the tooth (marked here in purple) and into the gum and jawbone. This path is known as a root canal because it helps to keep the tooth rooted in place. 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 (gingivitis) or the tissue and bones that support your teeth (periodontitis).

Root Canal Treatment

Root canal treatment is designed to save the tooth and prevent the spread of infection. The damaged pulp is removed from the tooth and the root canal is then cleaned of all bacteria. After the bacteria has been removed, the root canal and pulp are filled in using an artificial substance, before being sealed.

Is root canal treatment 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.

Is it available on the NHS?

Root canal is performed under NHS Band 2, however, some cases can be quite complex and the root form difficult to clean out. In these cases your dentist may suggest you be referred to an Endodontist to improve the success rate of the treatment. An Endodontist is a dentist with specialist training, equipment and experience to deal with them well. A specialist will use a surgical microscope during treatment, to magnify the tooth to approximately x20, to enhance success rates. Unfortunately, there are no Endodontic provisions under the NHS. Options available are Private referral or Referral to Dental Hospital for treatment by a Trainee Endodontist, however, the wait for this option can be very lengthy.

If your dentist recommends referral to an Endodontist, your options and reason for referral will be discussed thoroughly.

Inside the tooth’s hard outer layers, there is an area called the pulp or nerve. This can become damaged due to decay, deep cavities or injury. The damage usually results in painful inflammation or infection of the pulp. When this occurs, root canal treatment is the only way of saving the tooth and permanently relieving pain and infection.

Root canal treatment involves cleaning the infected or damaged pulp tissue from inside the tooth and replacing it with a permanent filling material called gutta-percha.

The treatment can often be done in one session, or occasionally multiple visits.

There are some scenarios where a general dentist may struggle to complete root canal treatment or their treatment may be unsuccessful (infection remains). These include:

  • Blocked root canals
  • Curved root canals
  • Unable to locate root canals
  • Instruments breaking within the root canal
  • Root damage during treatment
  • Unexplained pain

In these scenarios your dentist may refer you to a dentist with enhanced skills in Endodontics. At Boston Dental Centre, Dr Anand Subramanian accepts private patients directly and referrals from practices all over the Lincolnshire.

He has successfully completed a 2 year Post Graduate Diploma in Endodontics at the prestigious-Kings College London which he passed with a Distinction.

Endodontic treatment carried out at Boston Dental Centre is completed using a surgical microscope, is private only which allows for superior visualisation of the small root canals and more optimal cleaning. Often there are ‘additional’ root canals which are found using a microscope and these are all sources of bacteria which could lead to future infections or failed treatment if not found.

Endodontic treatment has a high success rate. Even if previous root canal has failed, it is possible in many cases to re-do the treatment with a successful outcome, rather than having the tooth extracted.
