Root Canal Treatment in Hilbert
We know root canal therapy has a reputation. Here is what the procedure actually involves — step by step, with no surprises.
When infection reaches inside the tooth
Root canal therapy has a cultural reputation that does not match the modern clinical reality. The Australian Dental Association notes that endodontic (root canal) treatment has a documented success rate of approximately 86–98%, depending on the tooth and complexity of the case. If someone has told you that you need a root canal, or you suspect you might, the anxiety you feel is understandable — and worth addressing before anything else.
A root canal removes infected or inflamed pulp tissue from inside the tooth root canals, cleans and shapes them, fills them with a biocompatible material, and seals the tooth to prevent reinfection. As part of our [restorative dentistry](/restorative-dentistry) services, the procedure preserves your natural tooth — the alternative is extraction.
Symptoms that typically indicate root canal treatment may be needed include spontaneous throbbing pain, prolonged sensitivity to hot or cold, swelling near the tooth, tenderness when biting, or darkening of the tooth. If you are experiencing severe tooth pain, our [emergency dentist](/emergency-dentist) service can assess you promptly. Your dentist will confirm the diagnosis with X-rays and clinical assessment before recommending treatment.
The procedure, step by step
This is the most important section on this page. Knowing exactly what happens — and what you will feel at each stage — is the most effective way to reduce the anxiety that surrounds this procedure.
Assessment and Imaging
Your dentist examines the tooth and takes an X-ray to confirm the infection and assess the number of root canals involved. The treatment plan — including the number of appointments, expected duration, and cost — is explained before any work begins.
What you feel: No discomfort. This is a diagnostic step.
Local Anaesthetic
Local anaesthetic is administered to numb the tooth and surrounding area. The injection may cause a brief sting or pinch, after which the area becomes fully numb. Your dentist will confirm numbness before proceeding.
What you feel: Brief pinch from the injection, then full numbness.
Dental Dam Placement
A thin rubber sheet (dental dam) is placed over the tooth to isolate it from the rest of your mouth. This keeps the treatment area clean and prevents debris from entering your throat.
What you feel: Mild pressure. The dam may feel unusual but is not uncomfortable.
Access and Pulp Removal
A small opening is made in the crown of the tooth to access the pulp chamber. The infected or inflamed pulp tissue is carefully removed using fine instruments. The root canals are located and opened.
What you feel: Pressure and vibration — not sharp pain. If you feel anything unexpected, raise your hand and additional anaesthetic can be applied.
Canal Cleaning and Shaping
The root canals are cleaned, shaped, and irrigated with antibacterial solution to remove all infected tissue and bacteria. This is the most time-intensive step — it may take 30 to 60 minutes depending on the number of canals.
What you feel: Pressure and occasional vibration. Some patients describe a faint irrigation sensation.
Filling and Temporary Restoration
The cleaned canals are filled with gutta-percha — a biocompatible rubber-like material — and sealed. A temporary filling is placed to protect the tooth until a permanent crown can be fitted. Your dentist will provide post-treatment care instructions.
What you feel: Minimal sensation. The anaesthetic is still active at this stage.
Myths vs reality
Root canal therapy is surrounded by outdated beliefs. Here is what the current clinical evidence actually shows:
“Root canals are extremely painful”
The procedure is performed under local anaesthetic. Most patients compare the discomfort to that of having a filling placed. The pain that leads to needing a root canal is typically far worse than the treatment itself.

“It is better to just extract the tooth”
Preserving your natural tooth has well-documented clinical advantages. Extraction leads to bone loss in the jaw, potential shifting of adjacent teeth, and the need for a replacement (implant, bridge, or denture) — which is typically more involved and more costly than root canal therapy.

“Root canals cause systemic illness”
This claim originates from research published in the 1920s that has been thoroughly discredited by modern evidence. Multiple peer-reviewed studies and professional bodies — including the American Association of Endodontists and the Australian Dental Association — confirm there is no credible evidence linking root canal therapy to systemic disease.

“Root canal treated teeth do not last”
With proper care and a well-fitted crown, teeth treated with root canal therapy can function for many years. The longevity depends on the quality of the restoration, the tooth location, and the patient’s oral hygiene. Individual outcomes vary.

How we manage your comfort
We understand that root canal therapy carries more anxiety than most dental procedures. Here is what Sienna Smiles does specifically to address that:
Local anaesthetic is always used
The tooth and surrounding area are fully numbed before any work begins. If you feel anything during the procedure, raise your hand — additional anaesthetic can be applied immediately.
You can pause at any time
A simple hand signal pauses the procedure. There is no pressure to push through if you need a moment. Your dentist will check in with you throughout.
Every step is explained beforehand
Your dentist describes what is about to happen before each step of the procedure. No surprises. Knowing what comes next is one of the most effective ways to manage anxiety.
Sedation options are available
For patients with significant dental anxiety, nitrous oxide (happy gas) or oral conscious sedation may help manage anxiety during the procedure. Suitability is assessed at consultation.
Learn about sedation optionsPost-treatment care plan provided
You will receive clear instructions on managing any mild discomfort after the procedure, including recommended pain relief and what to expect in the days following treatment.
