Toothcare Root Canal Therapy

Root canal or endodontic treatment is a process whereby inflamed or dead pulp tissue is removed from the inside of the tooth, enabling a tooth that was causing pain to be retained.

Dental pulp is the soft living tissue in the canal that runs through the centre of a tooth. Once a tooth is fully formed it can function normally without its pulp and be kept indefinitely.

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

Subsequently a crown or complex restoration to restore or protect the tooth is usually necessary, as a tooth after undergoing root canal therapy is more likely to fracture.

If you have a damaged tooth, root canal treatment may help to save it. Inside your tooth is soft tissue containing connective tissue cells, nerves, and blood and lymph vessels, known as the tooth pulp. When the pulp cannot repair itself from disease or injury, it dies. A fracture in a tooth or a deep cavity commonly cause pulp death, as the pulp is exposed to bacteria found.

This dead (necrotic) pulp tissue is a great nutrient for bacteria and when they colonise, it rots easily, it becomes gangrenous.  It is best to remove this gangrene before it spreads its toxins to the surrounding tissues. This infection in the local surroundings is called an abscess.  The whole tooth may be lost if the infection is left untreated. Root canal treatment can save your tooth.

Root canal treatment may involve one to three visits to the surgery.


1. An opening is made through the crown of the tooth into the chamber where the pulp is found.

2. The pulp is removed, and the root canal/s are cleaned and shaped into a form that can be filled easily.

3. Medications to prevent infection and sooth the situation may be placed in the pulp chamber.

4. Dr. Telford may leave the tooth open in order for it to drain, however often a temporary filling is placed in the crown of the tooth to protect it until your next visit. Antibiotics may be prescribed to help prevent infection.

5. The temporary filling will be removed, and after cleaning, the pulp chamber and root canal/s will be filled.

6. Finally, a crown (either porcelain or gold) will be placed over your tooth.
