Few dental procedures inspire as much anxiety as root canal treatment. Yet the vast majority of patients who have one are surprised by how routine it actually is. If your dentist has recommended a root canal, here's everything you need to know - from what the procedure involves to how much it costs and what happens if you skip it.
What Is Root Canal Treatment?
Root canal treatment (also called endodontic therapy) removes the soft tissue - called the pulp - from inside a tooth. The pulp contains nerves and blood vessels that helped the tooth develop, but once the tooth is fully grown, it can function perfectly well without it.
The procedure is needed when the pulp becomes infected or inflamed, usually because of:
- Deep tooth decay that has reached the pulp chamber
- A cracked or chipped tooth that allows bacteria in
- A traumatic injury to the tooth
- A faulty crown that lets bacteria underneath
- Repeated dental procedures on the same tooth
If the infected pulp is not removed, the infection can spread to the bone and surrounding tissue, forming an abscess - a painful pocket of pus that can cause swelling, fever, and serious complications.
Symptoms That May Indicate You Need a Root Canal
You won't always feel pain with a pulp infection. However, common warning signs include:
- Persistent toothache, particularly when eating or applying pressure
- Prolonged sensitivity to hot or cold that lingers after the stimulus is removed
- Swelling or tenderness in the nearby gums
- A small pimple (fistula) on the gum near the affected tooth
- Tooth discolouration - the tooth darkening compared to its neighbours
- Pain that radiates to the jaw, ear, or neck
A dental X-ray and clinical examination can confirm whether root canal treatment is needed. Sometimes the nerve dies quietly with no pain at all, only showing up on an X-ray as a shadow at the root tip (a periapical lesion).
What Happens During Root Canal Treatment
The procedure is done under local anaesthetic - you will be numb, not asleep. Here is what happens step by step:
Step 1: Anaesthetic and Access
Your dentist numbs the tooth and surrounding area. A small rubber sheet called a dental dam is placed around the tooth to keep it clean and dry. An opening is made through the top of the tooth to reach the pulp chamber.
Step 2: Removing the Pulp
Using very fine instruments called files, the infected pulp tissue is carefully removed from the pulp chamber and each root canal. The canals are shaped and smoothed to prepare them for filling.
Step 3: Irrigation
The canals are flushed with an antibacterial solution (usually sodium hypochlorite) to remove any remaining bacteria and debris.
Step 4: Filling the Canals
Once clean and dry, the canals are filled with a rubber-like material called gutta-percha, which is sealed in with dental cement to prevent reinfection. In some cases, a medicated dressing is placed and the tooth is temporarily sealed for a week or two before the final fill.
Step 5: Crown or Restoration
Because the tooth is now more brittle without its blood supply, a dental crown is usually placed to protect it - especially for back teeth. The crown is made from ceramic, porcelain-fused-to-metal, or zirconia, and is custom-made to match your other teeth.
How Many Appointments Does It Take?
Most root canals are completed in one to two appointments, depending on:
- Which tooth is being treated (front teeth are simpler; molars have more complex root systems)
- The severity of the infection
- Whether a specialist referral is required
At Serene Family Dental, we handle most root canals in-house. For complex cases involving unusual anatomy or retreatment of a previous root canal, we may refer you to a specialist endodontist.
Is Root Canal Treatment Painful?
The short answer: not during the procedure. The anaesthetic is very effective and most patients feel nothing more than pressure and vibration while work is being done.
Some people do experience mild discomfort for 2–5 days after treatment as the tissue settles. This is usually well controlled with ibuprofen or paracetamol. Full healing of any bone changes shown on X-ray can take several months, but you won't feel this.
The pain you might have been experiencing before treatment - from the infected pulp pressing against nerve endings - is typically relieved very quickly once the pulp is removed.
Root Canal Cost in Australia (2026)
Root canal treatment costs vary based on the tooth being treated and the complexity of the procedure:
| Tooth Type | Typical Cost Range |
|---|---|
| Front tooth (1–2 canals) | $800 – $1,400 |
| Premolar (2 canals) | $1,000 – $1,800 |
| Molar (3–4 canals) | $1,400 – $2,500 |
| Crown (after root canal) | $1,500 – $2,200 |
These figures are indicative - the actual fee depends on the complexity of your specific tooth. We provide a full written cost estimate before starting any treatment.
Private health insurance: Most policies with major dental (Extras) cover contribute a rebate toward root canal treatment. The rebate amount varies significantly between funds and policy levels. We process all claims on-the-spot via HICAPS - you only pay the gap on the day.
Interest-free payment plans: We offer Afterpay and humm, so you can spread the cost of treatment over time if needed.
Root Canal vs Extraction: Which Is Better?
One common question is whether to simply extract the tooth rather than save it with a root canal. While extraction is cheaper upfront, it sets off a chain of consequences:
- Bone loss begins almost immediately at the extraction site, as the jawbone shrinks without a tooth root to stimulate it
- Shifting teeth - adjacent and opposing teeth drift toward the gap over time, affecting your bite
- Replacement costs - a dental implant, bridge, or denture will be needed to fill the gap, typically costing more than the root canal would have
Saving your natural tooth is almost always the better long-term outcome - both clinically and financially. Your own tooth is biologically superior to any replacement.
What Happens After Root Canal Treatment
In the days after treatment:
- Take pain relief as needed (ibuprofen is most effective for dental inflammation)
- Avoid chewing hard foods on the treated side until your crown is placed
- Continue brushing and flossing normally
- Attend your follow-up appointment to have the final crown or restoration placed
Long-term care:
- A root-canal-treated tooth with a crown can last as long as your natural teeth - often decades - with proper care
- Brush twice daily, floss daily, and attend regular check-ups and cleans
