A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.

How does tooth pulp get infected?

When pulp is damaged it breaks down, and bacteria begin to multiply within the pulp chamber. The bacteria and other dying pulp remnants can cause an infection or abscess on the tooth.

It is important to treat a dying tooth or a dead tooth as soon as possible, it’s because if left untreated it will affect the other surrounding nerve tissue and the bacteria from the dead tooth, it can spread and lead to the loss of additional tooth. Other alternative way to treat a dying or dead tooth is to remove the entire tooth. 

What is an Abscess?

an abscess is a collection of puss that has build up within the tissue of the body. A puss-filled pocket that forms at the end of a tooth’s root.

Signs and Symptoms of Abscess includes;

redness of the gums

pain in the surrounding’s of the tooth and gums

warmth sensation

swelling – the swelling may feel fluid-filled when pressed. 


Root Canal Treatment and Procedure

Initial Consultation

X-ray – to examine the infected tooth

Root Canal treatment and preparation

Infected tooth cleaning

Opening made in tooth

Infected tissue removed; canals cleaned

Canals filled with a permanent material ( guta-percha )

Opening sealed with filling. In some cases a post is inserted for extra support

New crown cemented onto rebuilt tooth

Requires two-separate visit / appointment.

Time Duration is usually takes 1 ½ hour – depends on the infected tooth.


Sometimes root canal treatment is completed in one appointment but usually two or three visits may be necessary – depends on how infected the teeth is.

The main purpose of endodontic treatment (root canal therapy) is to:

remove the diseased pulp

clean and shape the root canal system

disinfect the contaminated root canals

Obturate (fill) the root canal system to prevent re-infection and promote periradicular healing.
