How much does a root canal cost?
Quick answer
Root canal cost depends on which tooth (front teeth have fewer canals than molars), who does it, and whether the quote includes the core buildup and crown that usually follow.
A root canal removes infected nerve tissue from inside a tooth. The price varies mostly by tooth type and provider. But the biggest surprise is usually what comes after: most back teeth need a buildup and crown to stop them cracking. A fair estimate shows the full treatment, not just the canal.

What most people miss
The root canal is often only half the bill
Molars and premolars treated with a root canal usually need a core buildup and a crown afterwards. Those can cost as much as — or more than — the root canal itself. Ask for the full plan before you start.
How this price is built
Exam and X-rays
Diagnostic X-rays, sometimes a 3D scan for complex roots.
Tooth type
Front (usually one canal), premolar (one to two) or molar (three or more).
Root canal therapy
Cleaning, shaping and filling the canals.
Provider
General dentist or endodontist (root canal specialist).
Core buildup
Rebuilding the tooth's structure to support a crown.
Crown
Material (zirconia, porcelain, metal) and lab.
Temporary filling
Between appointments.
Follow-up
Post-treatment checks and X-rays.
What makes a quote high
Crown left off the quote
Root canal priced alone, with the crown arriving as a second surprise.
Retreatment
Redoing an old root canal is more complex and costs more.
Specialist referral
Endodontists typically charge more — sometimes worth it for difficult teeth.
Premium crown upsell
High-end crown materials without explaining the options.
Sedation add-ons
Sedation included without asking.
Itemised versus vague
A quote you can evaluate looks different from one you can't. This is what to look for, line by line.
| Item | A quote you can judge | A quote you can't |
|---|---|---|
| Tooth | Tooth number and canal count stated | Root canal |
| Provider | Dentist or endodontist named | Not stated |
| Buildup | Core buildup priced | Not mentioned |
| Crown | Crown material and fee listed | Crown to follow |
| Insurance | Estimated coverage shown | Insurance may cover |
Questions to ask before you approve
- Which tooth is it, and how many canals?
- Will I need a buildup and crown afterwards? What will they cost?
- Are you doing it, or referring me to an endodontist?
- What will my insurance likely cover?
- What are my options if I don't do the root canal?
What to ask your dentist
Copy these lines as they are. Politeness plus specifics gets answers.
- 1.“What's the full cost, including buildup and crown?”
- 2.“Which tooth, and how many canals?”
- 3.“Can you send a pre-treatment estimate to my insurance?”
When a high price is legitimate
A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.
- The tooth is a molar with three or more curved canals.
- It's a retreatment of a previous root canal.
- An endodontist handles a complex case.
- A crown is needed to protect the tooth.

Common questions
Is a root canal cheaper than an extraction?
The extraction is usually cheaper upfront, but replacing the missing tooth with an implant or bridge often costs more overall.
Do front teeth need a crown after a root canal?
Not always. Front teeth sometimes only need a filling. Back teeth usually need a crown.
Does insurance cover root canals?
Many plans cover part of a root canal as a basic or major service, subject to annual maximums. Ask for a pre-treatment estimate.
Should I see an endodontist?
For molars, retreatments or curved roots, a specialist may be worth the extra fee.
