How much does a root canal cost? For a molar, the national average is about $1,050, with most fees between $685 and $1,800, based on ADA fee survey data. That number only covers the root canal, though, and the crown that usually follows is a second bill.
I learned that the hard way. Two years into paying off my credit card, a back tooth started aching every time I drank something cold. I ignored it for most of a month because I was scared of the bill, and that’s how a weekday appointment turned into a Saturday emergency visit with my face swollen on one side. So this post is the one I wish I’d read before I waited: what a root canal costs, what insurance really pays, and how to time the work so your dental benefits don’t expire on December 31 with money still on the table.
How much does a root canal cost on average?
The clearest national number I found is from Pearl’s dental cost guide, which summarizes American Dental Association fee survey data. Its May 2026 update puts a molar root canal here:
- National average: $1,050.
- Typical range: $685 to $1,800.
- Most expensive states: Hawaii ($1,330), New York ($1,285) and D.C. ($1,230).
- Least expensive states: Oklahoma ($915) and Louisiana ($925).
Molars sit at the top of the price list because they have three or four canals to clean and seal. Pearl says a molar takes 60 to 90 minutes, while a front tooth with a single canal takes 30 to 45. The American Association of Endodontists says the same thing from the patient side: root canals on front teeth (incisors and canines) are generally less expensive.
Mine was a lower molar. Of course it was.
What makes one root canal cost more than another
Two people can walk out of the same office with very different bills. The AAE lists tooth location, case complexity, the restoration you need afterward, and where you live as the main factors. Pearl adds a few specifics:
- Who does it. Endodontists (root canal specialists) charge more than general dentists. The AAE notes they train at least two extra years after dental school, and many general dentists refer molar cases to them.
- First time or retreatment. Redoing a tooth that already had a root canal is harder and costs more.
- Narrow or hardened canals. These can need microscope work and extra time.
- Extras billed separately. Pearl’s quote checklist says the crown, the build-up (post and core) under it, and sedation beyond local anesthesia are often separate charges.
That last point is where my budget went sideways. I had a number in my head for “the root canal” and never asked what else was coming. The crown appointment was three weeks later, and it cost more than the root canal did.
Ask for the whole treatment plan in writing, crown included, before you say yes. The first number I heard was about half of what I paid.
The crown is a second bill (plan for both)
Pearl says a crown is “almost always required” after a molar root canal and is billed separately. Its national average for a porcelain crown is $1,560, usually somewhere between $1,015 and $2,670. When I put those two averages side by side, the total for one back tooth comes to roughly $2,610 before insurance, plus any build-up.
Whether you need a crown, which material, and how soon it has to go on are your dentist’s calls. I’m only talking about the bill here. But knowing the crown is likely means you can budget for the pair from the start instead of getting blindsided in week three like I did.
The safe budgeting move is to treat “root canal” as a two-line expense from day one. I broke down the second line in what a dental crown costs, state by state.
How much does a root canal cost with insurance?
According to Pearl, most PPO dental plans cover root canals at 50% to 80% after the deductible, up to the plan’s annual maximum. The AAE adds that many plans cover root canal treatment and that some require pre-authorization first. Crowns are often covered at a lower percentage than root canals, so check both lines in your plan.
The annual maximum is the number that trips people up. It’s the most your plan will pay in a plan year, and on many plans it resets when the new plan year starts, which for a lot of people is January 1. If you already had fillings or a deep cleaning this year, part of that maximum may be gone.
When I finally called my insurer (on hold for 22 minutes, with my cheek on an ice pack), I asked three questions and wrote the answers on a sticky note:
- What percentage do you cover for endodontics and for crowns? They’re often different.
- How much of my annual maximum is left this year? Get the dollar amount, not “you should be fine.”
- Do you need pre-authorization, and is my endodontist in network? An out-of-network specialist can change the math.
If your job lets you pick a dental plan during open enrollment, this is a good week to look at those lines. My post on what a dental cleaning costs explains how plans treat routine visits, which eat into the same maximum.
How much does a root canal cost without insurance?
Without insurance, you pay the full fee, so plan on the national average ($1,050 for a molar) plus the crown. That’s a big number, and it’s the reason so many of us wait, which can make things worse. Pearl lists abscess and infection spreading to the bone as what can happen when treatment is put off, and a tooth that fractures may not be savable.
A few ways to bring the out-of-pocket cost down without skipping care:
- Use pre-tax money. The IRS counts dental treatment as a medical expense in Publication 502, so HSA or FSA money can pay for a root canal and crown.
- Ask about an in-office payment plan. Many offices will split the bill into monthly payments. Ask whether there’s interest before you sign.
- Ask for a cash-pay price. Some offices knock a little off the fee if you pay in full on the day.
- Look into a dental school clinic. Supervised students often charge less. Appointments take longer, so this works best when you’re not in pain yet.
One thing I’d be careful with: a medical credit card with “no interest if paid in full.” If you don’t clear the whole balance by the deadline, deferred interest can land on the original amount. My guide to negotiating medical bills covers how to ask an office for a lower price or a longer plan before you reach for one.
Root canal vs. pulling the tooth
When the bill feels huge, extraction can sound like the budget option. The AAE’s take is that pulling the tooth “may appear less expensive at first” but rarely ends there, because a missing tooth usually needs an implant or a bridge. Those tend to cost more and take more appointments than a root canal.
I asked my dentist about extraction too, half joking. She didn’t laugh. She walked me through the gap a missing molar would leave and what replacing it would cost, and I paid for the root canal. That’s a medical decision between you and your dentist, but asking for both prices is a fair budgeting question.

A worked example: timing the work around December 31
This is the part I didn’t know about until a friend who works in a dental office told me. If you have insurance and part of this year’s maximum is already used, splitting the root canal and the crown across two plan years can change what you pay, as long as your dentist says the timing is safe for your tooth.
Here’s a hypothetical example using Pearl’s national averages and made-up plan terms: 80% coverage for root canals, 50% for crowns, a $1,500 annual maximum with only $600 left in 2026, this year’s deductible already met, and a $50 deductible in 2027.
| Line | Both in December 2026 | Root canal Dec 2026, crown Jan 2027 |
|---|---|---|
| Root canal fee (molar) | $1,050 | $1,050 |
| Crown fee (porcelain) | $1,560 | $1,560 |
| Plan would pay before the cap | $840 + $780 = $1,620 | $840 in 2026, $755 in 2027 |
| Plan actually pays | $600 (capped by what’s left) | $600 in 2026 + $755 in 2027 = $1,355 |
| You pay | $2,010 | $450 + $805 = $1,255 |
| Difference | $755 less by splitting across plan years in this example | |
If your maximum is untouched, the gap shrinks a lot. If you’re nearly tapped out, it grows. The only way to know is to get the “how much is left” number from your insurer.
Common mistakes when budgeting for a root canal
- Budgeting for the root canal only. On a molar, the crown is usually a separate bill that can be bigger than the first one.
- Assuming the plan pays its full percentage. The annual maximum caps it, and earlier work this year may have used part of it.
- Waiting until it hurts. Delay can turn a planned appointment into an emergency visit, and fewer options means less room to compare prices.
If you want context on how much households spend on health care overall, I keep a running list of budgeting statistics. If a bill like this would wipe out your savings, a small emergency fund is the next thing I’d build.

Frequently Asked Questions
How much does a root canal cost on a molar?
Pearl’s summary of ADA fee survey data puts the national average at about $1,050 for a molar root canal, with most fees between $685 and $1,800. A crown is usually needed afterward and is billed separately.
Is a root canal on a front tooth cheaper?
Usually, yes. The American Association of Endodontists says root canals on front teeth are generally less expensive, since they typically have one canal and take less time than a molar.
Does dental insurance cover root canals?
Many plans do. Pearl says most PPO plans cover root canals at 50% to 80% after the deductible, up to the annual maximum. Some plans require pre-authorization, so call your insurer before treatment.
Can I use my HSA or FSA for a root canal?
Yes. IRS Publication 502 includes dental treatment as a medical expense, so HSA or FSA money can pay for a root canal and the crown.
Is it cheaper to pull the tooth than get a root canal?
It can look cheaper at first. The AAE says a missing tooth usually needs an implant or bridge later, which tends to cost more. Ask your dentist for the price of both paths before you decide.
