Root Canal Treatment
Root Canal Treatment at Dental Nook
Root canal treatment at Dental Nook typically ranges from $1,000 to $3,000, depending on which tooth is being treated and how many canals it contains. Where a dental crown is needed afterwards, this is an additional cost. Fees are current for 2025 and subject to change — your dentist will provide a full itemised quote before any treatment begins.
The procedure removes infected or dying tissue from inside the tooth, thoroughly disinfects the internal canal system, and seals it permanently to prevent reinfection. Evidence from the research literature consistently supports its effectiveness: a meta-analysis reported a pooled success rate of 89% for conventional root canal treatment, and long-term clinical data shows that 97% of appropriately restored treated teeth remain functional a decade after the procedure.
At Dental Nook, root canal treatment is available for adult patients, with dedicated children’s root canal care also on offer. Patients experiencing dental anxiety can choose from happy gas, IV sedation, or sleep dentistry under general anaesthesia to make their experience as comfortable as possible.

Estimated root canal treatment fees at Dental Nook (current fees, before health fund rebates):
Root canal treatment involves several distinct clinical steps, each billed separately. The total cost depends primarily on the number of canals within the tooth being treated.
- Front tooth (1 canal): $900 – $1,600
- Premolar (1–2 canals): $1,250 – $2,000
- Molar (3–4 canals): $1,650 – $2,700
- Dental crown following root canal: $2,000 – $2,800 (where required)
Signs You May Need Root Canal Treatment
Inside every tooth sits the pulp — soft tissue containing nerves and blood vessels that nourish the tooth during development. When the pulp becomes irreversibly inflamed or infected, a condition known as irreversible pulpitis, root canal treatment is typically the pathway to saving the tooth. The following symptoms may indicate that the pulp is compromised:
- Persistent toothache: Pain that does not ease within a few seconds of the trigger, or that disturbs sleep at night, suggests nerve damage rather than ordinary sensitivity.
- Extended sensitivity to temperature: A sharp ache that lingers for 30 seconds or more after the hot or cold stimulus is removed — rather than passing quickly — is a meaningful warning sign of pulp inflammation.
- Discomfort when biting: Tenderness under pressure can point to an infection developing at the root tip, sometimes called a periapical abscess.
- A pimple-like swelling on the gum: A small raised bump near the affected tooth — sometimes called a gum boil or sinus tract — may be releasing pus from an infected root.
- Tooth darkening: A tooth that shifts to grey or deep yellow over time may have a non-vital (dying or dead) nerve, particularly following a history of dental trauma.
- Facial or jaw swelling: When infection spreads beyond the tooth into the surrounding soft tissue, it can produce visible swelling in the face or under the jaw. This warrants urgent attention.
Not every toothache signals a root canal. A number of conditions — including cracked teeth, gum disease, or referred pain — can produce similar symptoms. A thorough clinical examination and radiographs, and in some cases a 3D CBCT scan, are needed to confirm the diagnosis.
If you are experiencing any of these symptoms, contact Dental Nook promptly. We endeavour to see patients with dental pain as quickly as possible.
What Happens During Root Canal Treatment
1. Examination and imaging Your dentist examines the tooth and takes the necessary radiographs — or a CBCT (3D) scan for more complex cases — to assess the extent of the infection, map the canal anatomy, and plan the procedure.
2. Local anaesthesia The tooth and surrounding tissue are thoroughly numbed before treatment begins. The vast majority of patients feel only pressure — not pain — during the procedure. Patients who prefer additional comfort can opt for sedation (see below).
3. Dental dam placement A thin rubber sheet is fitted around the tooth to isolate it from the rest of the mouth. This keeps the operating area dry, prevents saliva contaminating the cleaned canals, and protects the patient from the irrigating solutions used during the procedure.
4. Accessing and removing the pulp A small opening is made in the crown of the tooth to reach the pulp chamber. Using precision endodontic instruments, the infected or inflamed pulp is carefully removed from the chamber and along each root canal.
5. Cleaning, shaping, and disinfection The canals are meticulously cleaned, shaped with fine files, and flushed with antibacterial irrigating solutions. This stage eliminates residual bacteria, clears debris, and prepares the canals to receive a complete, leak-proof seal in the next step.
6. Filling and sealing Once the canals are clean and fully dry, they are filled with gutta-percha — a biocompatible, rubber-like material — and sealed with adhesive cement. A temporary or permanent filling closes the access opening.
7. Restoration Most teeth that have undergone root canal treatment require a dental crown to restore their function and protect against fracture, particularly in the molar and premolar region where bite forces are greatest. Your dentist will advise whether a crown or a direct composite restoration is the most appropriate option for your specific tooth.
Does Root Canal Treatment Hurt?
During treatment: Local anaesthetic reliably numbs the tooth and surrounding area before anything begins. Most patients describe feeling some pressure and movement, but not sharp pain. If any discomfort is felt at any point, your dentist can adjust the anaesthetic immediately.
After treatment: Mild tenderness or sensitivity around the treated tooth in the days following the procedure is normal and expected. This settles relatively quickly and responds well to over-the-counter pain relief such as ibuprofen or paracetamol. Research indicates that post-operative discomfort typically peaks within the first 24 hours and resolves within a week for the majority of patients.
When to follow up: If pain intensifies after the first few days, or if swelling develops, contact your dentist. This may indicate a complication that needs prompt assessment.
Dental Nook offers happy gas, IV sedation, and general anaesthesia for patients who experience anxiety or who prefer additional comfort during the procedure. Your dentist will discuss which option suits your needs at your consultation.
Root Canal Treatment Under Sedation
Not every patient is comfortable with dental treatment while awake, and there is no obligation to manage it without support. At Dental Nook, we offer three levels of sedation to accommodate different needs:
- Nitrous oxide (happy gas): Inhaled through a small nose mask, nitrous oxide produces a calm, relaxed state while leaving you fully conscious and responsive. The effects wear off within minutes of removing the mask, allowing you to drive home afterwards.
- IV sedation (twilight sedation): Medication is delivered intravenously, producing deep relaxation and often leaving patients with little or no memory of the procedure. You remain technically conscious and responsive, but comfortably unaware. A specialist anaesthetist monitors you throughout.
- General anaesthesia (sleep dentistry): For patients with severe dental phobia, a pronounced gag reflex, or complex treatment requirements, general anaesthesia allows treatment to be carried out while you are completely asleep. This is administered by a specialist anaesthetist and is particularly useful for completing extensive treatment in a single appointment.
Root Canal vs Tooth Extraction: Which Is Right for You?
When a tooth is seriously infected or damaged, the two primary options are saving it with root canal treatment or removing it with an extraction. Both are clinically valid choices, and your dentist will recommend the most appropriate path based on your specific situation. Here is how they compare:
Root canal treatment preserves the natural tooth. The infection is cleared, the canals are sealed, and the tooth is restored with a filling or crown. Retaining the natural root maintains the bone structure of the jaw and the positional stability of neighbouring teeth. Long-term data shows that 97% of properly restored root-canal-treated teeth remain functional after 10 years — a compelling case for tooth preservation when structurally feasible.
Tooth extraction eliminates the tooth entirely. While it resolves the immediate infection, the resulting gap needs to be addressed — ideally with a dental implant, bridge, or denture — to prevent neighbouring teeth drifting and to restore bite function. Replacement adds significant time and cost to the overall treatment journey.
Approximate cost comparison:
- Root canal + crown: approximately $2,200 – $5,000
- Extraction + dental implant + crown: approximately $4,000 – $8,000
- Extraction only (without replacement): approximately $350 – $700
In most clinical scenarios where the tooth can be adequately restored, root canal treatment is the preferred approach. Extraction becomes the more appropriate recommendation when the tooth is severely fractured, lacks sufficient structure to support a crown, or when advanced bone loss from gum disease has undermined its long-term prognosis.
Your dentist will walk through both options, expected outcomes, and associated costs so you can make a fully informed decision about your care.
Do You Need a Crown After Root Canal Treatment?
For the majority of patients — particularly those having back teeth treated — the answer is yes. Once the pulp is removed, the tooth becomes considerably more brittle. Without the reinforcement of a dental crown, it is vulnerable to cracking or shattering under the forces of daily chewing.
Molars and premolars: A crown is strongly recommended. These teeth bear the heaviest functional loads, and clinical evidence consistently shows that root-canal-treated back teeth restored with crowns have significantly better long-term survival than those left with fillings alone.
Front teeth: The calculus is different. If the tooth retains good structural integrity and only a small access opening was required, a well-placed composite filling may provide adequate protection. Your dentist will assess the remaining tooth structure and make a recommendation accordingly.
It is important not to delay crown placement after completing root canal treatment. The temporary or permanent filling placed at the end of the procedure protects the tooth in the short term, but a crown should ideally be fitted within a few weeks to guard against fracture before permanent protection is in place.
How Long Does a Root Canal Last?
Root-canal-treated teeth can remain in service for decades with the right restoration and maintenance. Long-term clinical data following teeth over periods of up to 37 years shows 97% survival at 10 years and 81% at 20 years — outcomes that compare favourably with most tooth-replacement alternatives.
Several factors determine the longevity of a root-canal-treated tooth:
- Quality of the final restoration: Crown-restored teeth consistently outlast those left with fillings, particularly in the posterior region.
- Ongoing oral hygiene: Consistent brushing, daily flossing, and regular professional check-ups protect the treated tooth from new decay and gum disease at the margins.
- Tooth type: Front teeth generally achieve better long-term results than molars, which are anatomically more complex and subjected to higher bite forces.
- Bruxism (teeth grinding): Patients who grind their teeth place extraordinary mechanical stress on their dentition. A custom night guard significantly reduces the fracture risk for root-canal-treated teeth in these patients.
