Root Canal Therapy

These are cosmetic fillings made from a synthetic resin, and offer an excellent alternative to silver amalgam fillings. Since these materials are bonded to teeth, they are strong, durable and require minimal removal of tooth structure. The fillings are tooth coloured and are carefully matched to the shade of your tooth. When in place, they are virtually invisible. They restore your teeth to their natural beauty and help you look your best.


What is root canal treatment?

Root canal treatment (also called endodontics) is needed when the blood or nerve supply of the tooth (known as the pulp) is infected through decay or injury.

Why is root canal treatment needed?

If the pulp becomes infected, the infection may spread through the root canal system of the tooth.

This may eventually lead to an abscess. If root canal treatment (RCT) is not carried out, the infection will spread and the tooth may need to be taken out.

  • Sometimes a tooth needs a root treatment
  • This requires the exposure of the root system of the tooth
  • then the removal of the nerves and material within the root
  • A special material is now available
  • which is placed into the tooth roots
  • The material hardens and is then trimmed
  • The tooth can then be filled
  • Over time, this special material expands within the root
  • which prevents any bacteria from continuing to deay the tooth

Does it hurt?

No. A local anaesthetic is used and it should feel no different to having an ordinary filling done.

At the first appointment, the infected pulp is removed. Any abscesses, which may be present, can also be drained at this time. The root canal is then cleaned and shaped ready for the filling. A temporary filling is put in and the tooth is left to settle.

The tooth is checked at a later visit and when all the infection has cleared, the tooth is permanently filled.

What will my tooth look like after treatment?

In the past, a root filled tooth would often darken after treatment. However, with modern techniques this does not usually happen. If there is any discolouration, there are several treatments available to restore the natural appearance.

What if it happens again?

Root canal treatment is usually very successful. However, if the infection comes back the treatment can be repeated.

What if I don’t have the treatment?

The alternative is to have the tooth out. Once the pulp is destroyed, it can’t heal and it is not recommended to leave an infected tooth in the mouth. Although some people would prefer an extraction, it is usually best to keep as many natural teeth as possible.

Will the tooth be safe after treatment?

Yes. However, it is better to restore the tooth with a crown to provide extra support and strength to the tooth.

Where can this treatment be carried out?

Root canal treatment is a routine dental procedure, which your dentist will be happy to do for you.

What about aftercare?

Root-treated teeth should be treated just the same as any other tooth. Remember to clean your teeth at least once a day, preferably with a fluoride toothpaste. Cut down on sugary snacks, and keep them only to mealtimes if possible. See your dentist for regular check-ups.
