Root Canal Therapy – Endodontics

Root canal therapy or endodontics treats the inside of the tooth. This is necessary when the pulp becomes inflamed or infected by decay, large fillings, cracks, chips or trauma. If the pulp inflammation or infection is left untreated if can cause pain or an abscess.

During root canal treatment

During root canal treatment:

  • the infected pulp is removed
  • the inside of the tooth is carefully cleaned and disinfected
  • then filled and sealed with a rubber like material called gutta percha.

After root canal treatment

  • Afterwards, the tooth is restored with a crown or filling for protection.
  • After restoration, the tooth continues to function like any other tooth.

Our root canal treatment is very similar to having a routine filling and depending on the condition of the tooth you can expect a comfortable experience during and after your appointment.

What is Root Canal Treatment?

Root canal or endodontic treatment is a process whereby inflamed or dead pulp (blood and nerve supply) is removed from the inside of the tooth, enabling a tooth that was causing pain to be saved.

After removing the pulp, the root canals are cleaned, sterilised and shaped so that it can be completely sealed with a filling material to prevent further infection. The treatment can between 2-3 appointments, depending on how complex the tooth is, and how long the infection takes to clear.

A crown is recommended to restore or protect the tooth, as a tooth becomes fragile and is likely to fracture.

Why do I need root canal treatment?

If a tooth is damaged severely where the pulp is affected, root canal treatment is usually the only option to save the tooth. When the pulp becomes infected, it is best to remove it before it spreads to the tooth and surrounding tissues. The tooth may be lost if the infection is left untreated. Root canal treatment can save your tooth.

What does root canal treatment involve?

Root canal treatment typically involves 1-3 visits to the dentist.

STEPS INVOLVED:

  1. An opening is made through the tooth in order to locate the pulp (nerve and blood tissue).
  2. The pulp is removed, and the root canal/s are cleaned to remove any tissue and bacteria and shaped into a form that can be filled easily
  3. Medications to prevent infection may be placed in the canal of the tooth root.
  4. Often a temporary filling is placed in the crown of the tooth to protect it until your next visit.
  5. Once the tooth is deemed bacteria free a root filling is placed inside the canal.
  6. Finally, Dr Le may place a crown (either porcelain or gold) over your tooth.

A referral to an endodontist (specialist) may be required in complex cases.

Why does the pulp need to be removed?

The pulp when injured or diseased doesn’t have the ability to repair itself and will die. A resultant bacterial infection may occur forming an abscess in the root tip. This infection will subsequently damage the bone around the tooth. Pain and swelling can then result and if left untreated can lead to the tooth being extracted.
