What is a root canal?
During root canal treatment, the infected tissue is carefully removed, the canal is thoroughly cleaned and disinfected, and the tooth is sealed to prevent further infection. This allows you to keep your natural tooth while eliminating discomfort.

What happens during root canal treatment
- Diagnosis - digital imaging confirms the infection and maps the tooth's root anatomy.
- Numbing - the tooth is fully anaesthetised; modern root canal treatment is comparable in comfort to having a filling.
- Cleaning - the infected tissue is carefully removed and the canals are thoroughly cleaned and disinfected.
- Sealing - the canals are filled and sealed to prevent reinfection.
- Restoration - the tooth is restored, often with a same-day porcelain crown to return its full strength.
Signs you may need a root canal
- Persistent or severe tooth pain, especially when chewing or biting
- Prolonged sensitivity to hot or cold, even after the stimulus is removed
- Swelling or tenderness in the gums around the affected tooth
- Discolouration or darkening of the tooth
- A pimple-like bump on the gums, which may indicate infection
- Pain that comes and goes but continues to worsen over time
- Deep decay, cracks, or trauma to a tooth
In some cases a tooth may require root canal therapy even without obvious pain - which is why regular check-ups are essential for early detection.
Benefits of root canal treatment
- Relief from discomfort - treatment addresses the source of dental pain by removing infected tissue.
- Preservation of your natural tooth - avoiding extraction and more complex treatments such as implants or bridges.
- Protection of overall oral health - treating infection early prevents bacteria spreading to surrounding teeth, gums or jawbone.
- Restored function and appearance - once treated, the tooth can be restored with a crown for comfortable chewing and a natural look.
- Cost-effective long term - retaining your natural tooth is often more affordable than replacing it.
Risks and considerations
- Temporary sensitivity - mild discomfort for a few days after treatment is normal and resolves as the area heals.
- Complex root anatomy - narrow or curved canals can be more challenging; in uncommon cases additional treatment may be required.
- Weakened tooth structure - a protective crown is often recommended to restore strength.
- Risk of reinfection - if bacteria re-enter due to decay, cracks or delayed restoration, further treatment may be necessary.
We reduce these risks with advanced diagnostic imaging, meticulous technique, and personalised follow-up care.
Frequently asked questions
Is root canal treatment painful?
This is the great myth. With modern techniques and proper anaesthesia, root canal treatment feels much like having a filling - and since it removes the infected tissue, it's the treatment that ends the pain you came in with, not causes it.
How successful is root canal treatment?
Root canal therapy is a predictable, well-established procedure with a strong track record when performed with modern techniques and followed by proper restoration. Protecting the treated tooth with a crown and keeping regular check-ups gives it the best long-term outlook.
How long does root canal treatment take?
Usually two appointments, depending on the tooth and the complexity of the infection. A straightforward root canal can be completed in 60-90 minutes in a single visit; molars with multiple canals or significant infection may require two visits.
Is root canal treatment covered by insurance?
Many private health insurance policies include cover for root canal treatment, depending on your level of extras cover. Our team is happy to help you check your eligibility with your health fund.
