Overview
A root canal procedure (endodontic treatment) aims to save a tooth with an infected or inflamed nerve. The dentist removes the diseased pulp, disinfects the canals and seals them, then restores the tooth with a durable filling or crown.
The right next step balances diagnosis, urgency, long‑term tooth survival, comfort, cost and your preference to either save or replace the tooth. If you are unsure, an initial assessment with tests and X‑rays is the best way to compare options.
Do you need a root canal?
Common signs you may need a root canal include:
- Lingering pain to hot or cold (over 10–15 seconds after the stimulus)
- Throbbing pain, swelling, or a pimple on the gum
- Pain on biting or tapping the tooth
- Deep decay, a crack, or a heavily filled tooth now painful
- Darkening of the tooth after trauma
Diagnosis usually involves bite and cold tests, probing, and digital X‑rays. Sometimes a 3D scan is recommended for complex roots or to plan retreatment.
Root canal procedure: step by step
- Assessment and pain control: Confirm diagnosis, discuss options, and numb the tooth. Sedation can be arranged if needed.
- Access: A small opening is made through the biting surface or back of the tooth.
- Cleaning: Infected pulp is removed and canals are shaped and disinfected with antimicrobial solutions.
- Medication (if needed): A dressing may be placed inside the canals to help settle infection.
- Sealing: The canals are filled with a biocompatible material (gutta‑percha) and sealed.
- Restoration: A strong filling or a dental crown restores the tooth. Molars and heavily restored teeth often benefit from a crown for strength.
Visits: straightforward cases can be completed in one visit; infected or complex teeth may require two or more. A crown may be placed after the tooth has settled.
Treatment pathways compared
- Root canal treatment
- Pros: saves your natural tooth, relieves pain, maintains bite and jawbone.
- Cons: may require multiple visits; crown cost likely for back teeth.
- Best for: teeth with restorable structure and treatable infection.
- Root canal retreatment or apicoectomy
- Pros: options when previous treatment fails.
- Cons: higher complexity and cost; referral to an endodontist may be needed.
- Extraction (with replacement options)
- Dental implant: fixed, preserves bone; higher upfront cost. See dental implants.
- Dental bridge: fixed, quicker; may involve neighbouring teeth.
- Partial denture: most affordable; removable.
- Pulp capping or monitoring
- Pros: conservative in early or borderline cases.
- Cons: not suitable if the nerve is irreversibly inflamed or infected.
Costs in Australia
Fees vary by tooth, complexity, imaging, and whether care is with a general dentist or an endodontist. As a general guide:
- Front tooth (1 canal): $800–$1,400
- Premolar (1–2 canals): $1,000–$1,800
- Molar (3–4 canals): $1,400–$2,500+
- Crown after treatment (if recommended): $1,400–$2,000+
- 3D scan, sedation or specialist referral may add to costs.
Private health extras may contribute. Medicare generally doesn’t cover adult dental; eligible children may access the Child Dental Benefits Schedule. If a tooth cannot be predictably restored, discuss alternatives such as extraction with an implant, bridge or denture.

Recovery and what to expect
- Pain relief: tenderness for 1–3 days is common; anti‑inflammatories usually help.
- Eating: chew on the opposite side until the final restoration is placed.
- Work and driving: most people return to normal activities the same day.
- Antibiotics: only used when there is spreading infection, fever or swelling.
- Final restoration: a crown or onlay is often advised for back teeth to reduce fracture risk.

Risks, success and longevity
- Success rates are commonly reported around 85–97% for well‑indicated cases.
- Risks include reinfection, missed canals, fracture in heavily filled teeth, or persistent symptoms.
- Protection with a quality restoration and good oral hygiene improves longevity.
- If problems recur, options include retreatment or surgical endodontics (apicoectomy).
How to choose a provider
- Experience with molars and complex anatomy; use of rubber dam and rotary instruments.
- Imaging options (digital X‑rays, cone beam CT for complex cases).
- Clear plan for restoration (filling vs crown) and long‑term maintenance.
- Transparent itemised quote and staged treatment if needed.
- When to consider an endodontist (specialist): complex roots, retreatment, broken instruments, or persistent infection.

Urgency: when to act
- Seek urgent care for facial swelling, fever, spreading pain, or difficulty swallowing.
- Persistent night pain or pain that lingers after hot/cold is unlikely to resolve without treatment.
- If you can’t have a root canal immediately, ask about temporary measures to control pain and infection.
Questions to ask at an appointment
- What is the diagnosis and how certain is it?
- Is treatment urgent or can it be staged?
- What are my options (save vs replace) and your recommendation?
- How many visits, total time, and likely total cost?
- Do I need a crown and why?
- What are the chances of success and alternatives if it fails?
