What a Root Canal Costs in Darwin (2026)
A Transparent Guide to Pricing, Health Fund Cover, and Payment Options
One of the most common questions we hear at Compass Dental Care is: How much does a root canal actually cost?
It’s a fair question, and there isn’t a single answer — because a root canal on a front tooth and a root canal on a back molar are two very different amounts of work. The honest version is: it depends on the number of canals inside the tooth. A front tooth usually has one canal. A molar can have three or four. Every canal has to be individually cleaned, shaped, and sealed, so the more canals a tooth has, the more the treatment costs.
At Compass Dental Care in Parap, root canal treatment (endodontics) generally ranges from around $1,200 for a single-canal front tooth up to about $2,800 for a three- or four-canal molar. The crown that usually goes on the tooth afterwards is a separate, significant cost on top of that.
Rather than leave you guessing, this guide breaks down exactly what drives the price, shows you our actual fees with the ADA item numbers, walks through worked examples for real cases, and explains what your health fund is likely to pay. And whatever your situation, the number that matters is the one on your itemised written quote — which we give you after your consultation and X-ray, before any treatment begins.
What Determines the Cost?
The total cost of a root canal is built from several components. Understanding each one makes the final quote make sense.
1. Number of Canals
This is the single biggest factor. Inside every tooth root are one or more narrow canals containing the nerve and blood vessels. Root canal treatment means cleaning out and sealing each canal individually.
- A front tooth typically has 1 canal — the least work, so the lowest cost.
- A premolar usually has 2 canals.
- A molar (the big grinding teeth at the back) usually has 3 or 4 canals — the most work, so the highest cost.
Because the fee is built canal by canal, a four-canal molar simply involves more treatment steps than a single-canal incisor. That’s why the range spans from around $1,200 to around $2,800.
2. Which Tooth
The type of tooth tells your dentist roughly how many canals to expect and how accessible they are:
- Front teeth (incisors and canines) — Usually 1 canal, straight and easy to reach at the front of the mouth. Lowest cost.
- Premolars — Usually 2 canals. Mid-range.
- Molars — Usually 3–4 canals, sitting right at the back of the mouth where access is harder. Highest cost.
Your dentist confirms the actual canal count from your X-ray, and occasionally a tooth has an extra canal that isn’t obvious until treatment begins — which is one reason we re-quote if the picture changes (more on that below).
3. Complexity
Not every root canal is straightforward. Several things can make a tooth more complex — and therefore more time-consuming — to treat:
- Curved or narrow canals that are harder to clean and shape all the way to the tip.
- Calcified canals that have partly closed over, common in older teeth or teeth that were injured years ago.
- Retreatment — reworking a tooth that had a root canal previously and is now causing problems again. The old filling material has to be removed before the canals can be re-cleaned and re-sealed, which adds time and cost compared with a first-time root canal.
Your dentist assesses complexity from your X-ray and examination during the consultation.
4. X-rays and Imaging
You can’t treat a canal you can’t see. Imaging is part of every root canal:
- Periapical X-ray (ADA 022, $54) — A small, detailed X-ray of the whole tooth including the root tip. This is taken on every root canal case, usually more than once (before, during, and after treatment) to confirm the canals are fully sealed.
- CBCT / 3D scan (ADA 026, $200) — A three-dimensional scan used only for more complex cases, such as a tooth with unusual anatomy or a retreatment where the dentist needs to see exactly what’s going on. Not required for most straightforward cases.
If you’ve had recent imaging done elsewhere, bring it along — it may save you a repeat.
5. The Crown Afterwards
This is the part people often don’t budget for. A tooth that’s had a root canal — especially a back tooth — becomes more brittle and is at real risk of cracking under chewing forces. To protect it, we almost always recommend a crown (a custom-made cap that covers the whole tooth) once the root canal is complete.
The crown is a separate procedure with its own fee — a full porcelain crown at Compass Dental Care is $2,402 (ADA 613). It’s a significant cost, and it’s why the “all-in” figure for a back-tooth root canal is much higher than the root canal fee alone. On front teeth a crown isn’t always needed; on molars it almost always is. Your dentist will tell you clearly whether your tooth needs one.
You can read more on our dental crowns page.
6. Consultation Fee
Before any treatment, you need an examination and diagnosis. Your initial consultation (ADA 014, $98) includes the exam, review of your X-ray, the diagnosis, and a discussion of your options. This is a separate fee from the root canal itself, and it’s where your itemised written quote comes from.
Compass Dental Care — Root Canal Fees
The following table shows actual fees at Compass Dental Care in Parap (Standard fee schedule, updated April 2026). Your final cost depends on which components your specific tooth needs — above all, how many canals it has.
| Procedure | ADA Code | Fee |
|---|---|---|
| Consultation | 014 | $98 |
| Comprehensive oral examination | 011 | $98 |
| Periapical / bitewing X-ray (per film) | 022 | $54 |
| Panoramic OPG X-ray | 037 | $121 |
| CBCT / 3D scan (complex cases) | 026 | $200 |
| Root canal preparation — 1st canal | 415 | $394 |
| Root canal preparation — each additional canal | 416 | $255 |
| Root canal obturation (filling) — 1st canal | 417 | $394 |
| Root canal obturation — each additional canal | 418 | $255 |
| Pulp extirpation (emergency pain relief) | 419 | $265 |
| Provisional (temporary) restoration | 572 | $189 |
| Full porcelain crown (non-metallic) | 613 | $2,402 |
| Happy gas sedation (per 30 minutes) | 943 | $144 |
These are estimates to help you plan. Your dentist will provide an accurate, itemised quote after your consultation and X-ray, based on your specific tooth.
How the Fee Is Built
Once you see how a root canal is coded, the pricing stops being a mystery. Treating a canal happens in two stages, and each canal is billed for both stages:
- Preparation — cleaning and shaping the canal. The first canal in a tooth is ADA 415 ($394); every additional canal in the same tooth is ADA 416 ($255).
- Obturation (filling) — sealing the cleaned canal so bacteria can’t get back in. The first canal is ADA 417 ($394); every additional canal is ADA 418 ($255).
So a single-canal front tooth is billed one 415 + one 417. A two-canal premolar adds one 416 + one 418. A three-canal molar adds two 416s + two 418s, and so on. On top of the canal work you have the consultation, the X-rays, and a provisional (temporary) restoration (ADA 572, $189) — a temporary filling that seals the tooth between or after visits.
That’s the whole logic: more canals means more preparation and obturation fees, which is exactly why a molar costs more than a front tooth. Nothing is hidden — you can add it up yourself from the table above.
What a Typical Case Costs
Here are three worked examples so you can see how the numbers come together. These are estimates — your written quote after consultation is the accurate figure.
Front tooth (1 canal):
- Consultation (014): $98
- Periapical X-ray (022): $54
- Root canal preparation, 1st canal (415): $394
- Root canal obturation, 1st canal (417): $394
- Provisional restoration (572): $189
- Subtotal: about $1,129 — with follow-up imaging, about $1,200. Crown extra (often not needed on front teeth).
Premolar (2 canals):
- Everything in the front-tooth example above, plus:
- Preparation, additional canal (416): $255
- Obturation, additional canal (418): $255
- Subtotal: about $1,639. Crown extra.
Molar (3 canals):
- Consultation (014): $98
- Periapical X-ray (022): $54
- Preparation, 1st canal (415): $394
- Preparation, 2 additional canals (416 ×2): $510
- Obturation, 1st canal (417): $394
- Obturation, 2 additional canals (418 ×2): $510
- Provisional restoration (572): $189
- Subtotal: about $2,149. A four-canal molar comes to about $2,659, up to roughly $2,800. Crown extra — and on a molar, almost always needed.
Root canal + crown — the all-in figure:
Because a crown protects the treated tooth long-term, the realistic total for a back tooth includes the porcelain crown (ADA 613, $2,402):
- Front tooth root canal + crown: roughly $3,600
- Molar root canal + crown: roughly $5,200
We spell all of this out on your itemised quote so there are no surprises — you’ll see the root canal and the crown as separate lines, and you decide when to proceed with each.
Root Canal vs Extraction and Implant — The Long-Term Cost
When a tooth needs a root canal, the alternative is usually to take the tooth out. Pulling the tooth is cheaper on the day — but it leaves a gap, and a gap generally needs to be filled to keep the bite working and stop neighbouring teeth from drifting.
The most complete way to replace a missing tooth is a dental implant, which is a multi-stage treatment carried out over several months (the implant post, healing time, and then a crown on top). It is a multi-thousand-dollar treatment — typically well above the cost of saving the natural tooth with a root canal and crown.
So while a root canal (and crown) is a real investment, saving your own natural tooth is usually the more economical path over the long term than removing it and later replacing it with an implant. That said, not every tooth can be saved. Your dentist will give you an honest assessment of whether root canal treatment is the right call, and what the alternatives cost, before you decide.
Health Fund Coverage — You Need “Major Dental”
This is the single most important thing to understand about health fund cover for a root canal: root canal treatment (endodontics) is classified as major dental, not general dental. So is the crown that follows it.
That matters because a basic extras policy often only covers general dental — the exams, cleans, and simple fillings. To get a rebate on a root canal, your extras cover has to specifically include major dental. If your policy is general-dental-only, you may get little or nothing back on the root canal itself.
Here’s what to check with your fund:
- Does your extras policy include major dental? Root canal (endodontics) and crowns both sit in this category. General-dental-only cover typically won’t rebate them.
- What’s your annual limit? Major dental usually draws on an annual benefit limit, and a root canal plus a crown can use up a large chunk of it — or exceed it — in a single year.
- Is there a waiting period? Major dental commonly has a 12-month waiting period. If you’ve recently taken out or upgraded your policy, you may not be able to claim yet.
- How much is the rebate? The exact amount varies by fund and by your level of cover. Two people with “extras” can get back very different amounts depending on their specific policy.
HICAPS on the spot. At Compass Dental Care we process health fund claims on the spot with HICAPS, so you find out your gap (the difference between our fee and what your fund pays) immediately — you only pay the gap on the day. Just bring your health fund card to your appointment. If you’d like to check your cover in advance, call your fund and ask what they pay on the ADA item numbers on your treatment plan (415, 416, 417, 418 for the root canal, and 613 for the crown).
Medicare and CDBS
Medicare does not cover routine root canal treatment. Standard dental care, including endodontics, sits outside Medicare for adults.
The one exception is for children. The Child Dental Benefits Schedule (CDBS) may cover eligible children aged 0–17 for a range of dental services, up to $1,158 over a two-year period. Root canal treatment can fall within eligible services for a qualifying child. Whether your child is eligible depends on your family’s circumstances — check with Medicare or ask our team to help you confirm, and we can process CDBS claims for eligible children.
What If You Don’t Have Health Insurance?
If you don’t have private health insurance, you’re paying the full fee out of pocket. That’s manageable with a bit of planning:
- Pay as you go. Root canal treatment often happens across more than one appointment, which naturally spreads the cost. The crown is a separate stage later, so it doesn’t all land at once.
- Prioritise the urgent treatment. If you’re in pain, the priority is relieving it and saving the tooth — the crown can follow once the tooth has settled. Ask your dentist what’s genuinely urgent versus what can wait.
- Don’t delay. This is the big one. A tooth that needs a root canal won’t get better on its own. Left too long, the infection can spread and the tooth can become unsavable — at which point the only option is extraction, and then usually an implant to fill the gap. That path costs more than the root canal you were trying to avoid. Acting sooner is almost always the cheaper option in the end.
If you’re dealing with sudden pain, our emergency dental visits can relieve it quickly — sometimes with pulp extirpation (ADA 419, $265) to settle the tooth before full root canal treatment.
Payment Plans
Cost shouldn’t be the reason you delay treatment that saves a tooth. At Compass Dental Care we offer Zip Pay and Zip Money, which let you spread the cost of your root canal (and crown) into manageable payments rather than paying the full amount up front.
Ask our team about setting up a payment plan when you receive your quote — we’re happy to talk through the options so the numbers work for you.
How to Get an Accurate Quote
A general price range is useful for planning, but the only way to know your exact cost is a consultation with an X-ray. Here’s how it works:
- Book a consultation — book online or call our practice.
- X-ray — we take a periapical X-ray (and a CBCT only if your case is complex) to see the tooth, its roots, and how many canals it has.
- Examination and diagnosis — your dentist examines the tooth and confirms whether root canal treatment is the right option.
- Itemised written quote — you receive a written, itemised quote listing each component with its ADA item number, before any treatment starts. You’ll see the root canal and any crown as separate lines.
- Health fund check — we help you check your cover using the item numbers on your plan, and with HICAPS you’ll know your gap on the day.
- Your decision — you decide when to proceed. There’s no pressure.
And if the picture changes once treatment begins — for example, the tooth turns out to have an extra canal that wasn’t visible on the X-ray — we re-quote before proceeding, so the final cost is never a surprise.
Frequently Asked Questions
Can I get a quote over the phone?
We can give you a general price range over the phone, but an accurate quote needs a consultation and an X-ray. The cost depends on how many canals your tooth has and how complex it is, and we can only assess that by looking at the tooth and its imaging. After your consultation you get an itemised written quote before any treatment.
Does my health fund cover a root canal?
It depends on your policy. Root canal treatment is classified as major dental, so your extras cover has to specifically include major dental — general-dental-only cover usually won’t rebate it. Major dental also commonly carries a 12-month waiting period, and the rebate amount varies by fund and level of cover. We process claims on the spot with HICAPS so you know your gap immediately. To check in advance, ask your fund what they pay on ADA items 415, 416, 417 and 418.
Why do I also need to pay for a crown?
A tooth that’s had a root canal becomes more brittle and can crack under normal chewing — especially a back tooth. A crown caps and protects it so it lasts. The crown is a separate procedure with its own fee (a full porcelain crown is $2,402, ADA 613). On molars it’s almost always recommended; on front teeth it isn’t always needed. Your dentist will tell you clearly whether your tooth needs one.
Is a root canal cheaper than an implant?
Generally, yes — and it keeps your natural tooth, which nothing replaces as well. The alternative to a root canal is usually extraction, and filling the resulting gap most completely means a dental implant, which is a multi-stage, multi-thousand-dollar treatment carried out over several months. Saving the natural tooth with a root canal (and crown) is usually the more economical path over the long term. Your dentist will give you an honest comparison for your specific tooth.
What’s the item number for a root canal?
There isn’t one single number — a root canal is billed canal by canal, in two stages each. Preparation is ADA 415 (first canal) and 416 (each additional canal); obturation (filling) is ADA 417 (first canal) and 418 (each additional canal). A front tooth uses 415 + 417; a three-canal molar adds two 416s and two 418s. These are the numbers to quote to your health fund.
Why is a molar more expensive than a front tooth?
Because a molar has more canals. A front tooth usually has just 1 canal, while a molar usually has 3 or 4. Each canal has to be individually cleaned, shaped, and sealed, and each one adds a preparation fee (416) and an obturation fee (418). More canals means more work, which is why a molar sits at the top of the range and a front tooth at the bottom.
How much does a root canal cost at Compass Dental Care?
Root canal treatment generally ranges from about $1,200 for a single-canal front tooth up to about $2,800 for a three- or four-canal molar. A crown, where needed, is a separate cost — a full porcelain crown is $2,402. So an all-in figure is roughly $3,600 for a front tooth and roughly $5,200 for a molar with a crown. Your itemised written quote after consultation gives you the exact figures for your tooth.
Do you offer anything to help me relax during treatment?
Yes — we offer happy gas (nitrous oxide) sedation at $144 per 30 minutes (ADA 943) to help you feel calm and comfortable during your root canal. We also use Calaject, a computer-controlled anaesthetic system that makes the numbing injection itself far more comfortable — most patients barely feel it. Ask our team if you’d like either included in your treatment plan.
Ready to Find Out What Your Root Canal Will Cost?
The best next step is a consultation. We’ll examine the tooth, take an X-ray, tell you honestly whether a root canal is the right option, and give you a clear, itemised written quote — including any crown — before you commit to anything. We’ll also help you check your health fund cover and set up a payment plan if you’d like one.
