With dental insurance, your root canal cost with insurance usually drops to about $200 to $900 out of pocket for the procedure itself, because most plans cover 50% to 80% after your deductible. The catch most people miss is the crown. Back teeth almost always need one afterward, and it is billed separately, which can push your total out-of-pocket for a root canal plus crown to roughly $600 to $1,800. Your final cost depends on the tooth, your plan’s annual maximum, and whether you are in-network. Ask for a written predetermination before you start, so there are no surprises.

How Much Is a Root Canal With Insurance?
Here is the direct answer. Your root canal cost with insurance for the procedure alone is usually about $200 to $900 out of pocket. Most dental plans treat a root canal as a basic or major restorative service and cover 50% to 80% of the fee after you meet your deductible, up to your annual maximum.
So if a molar root canal is billed at $1,200 and your plan covers 70%, insurance pays about $840 and you pay around $360, plus any unmet deductible. That sounds manageable, and it is, until you add the crown. The crown that protects the tooth afterward is a separate procedure with its own cost and its own coverage, and it is the single biggest reason people get surprised by their bill. This guide breaks down the cost by tooth, explains why some quotes jump to $3,000, shows how the big insurers handle it, and gives you the exact steps to lock in your real price before treatment.
Root Canal Cost by Tooth: Front, Premolar, and Molar
The tooth being treated is the biggest driver of price. Front teeth have one canal and are simplest. Molars have three or four canals, sit at the back, and cost the most. Here is the procedure-only cost, before and after typical insurance.
| Tooth type | Without insurance | Out-of-pocket with insurance (50–80% covered) |
|---|---|---|
| Front (incisor or canine) | $700 – $1,100 | about $150 – $550 |
| Premolar (bicuspid) | $800 – $1,400 | about $200 – $700 |
| Molar (back tooth) | $1,000 – $1,800 | about $250 – $900 |
A few notes. An endodontist, the specialist for root canals, usually charges 20% to 30% more than a general dentist, which is often worth it for a difficult molar. A molar root canal averages around $1,200 to $1,500 nationally. And these numbers are the root canal only. They do not include the crown, which we cover next.
Why Is My Root Canal $3,000? The Crown Is the Catch
If you got a quote near $3,000, you are almost certainly looking at a molar root canal plus a crown, not the root canal alone. This is the most important thing to understand about root canal pricing.
About 90% of back teeth need a crown after a root canal, because removing the infected pulp leaves the tooth brittle and prone to cracking. That crown is a separate procedure, and it usually costs $800 to $2,000 on its own, sometimes up to $3,000 for premium materials. Add a core build-up or a post, which some teeth need to hold the crown, and the total climbs further. So the all-in cost of a root canal plus crown without insurance is commonly $1,600 to $3,200, and a molar with a ceramic crown and a specialist can top $4,000. With insurance, the combined out-of-pocket for the root canal plus crown usually lands between $600 and $1,800. One trap to watch: both the root canal and the crown count against your annual maximum, so if you have already used your benefits this year, insurance may pay little or nothing toward the second procedure.
How Dental Insurance Covers Root Canals
Knowing the moving parts helps you predict your bill. Four things decide what you actually pay.
Coverage percentage is how much your plan pays, usually 50% to 80% for a root canal, classified as a basic or major service. Your deductible is what you pay first each year before coverage kicks in, typically $50 to $150. Your annual maximum is the cap on what the plan will pay in a year, usually $1,000 to $2,000, and once you hit it, you pay the rest yourself. Finally, in-network versus out-of-network matters a lot: in-network, you pay a percentage of a discounted fee, so staying in-network meaningfully lowers your cost. Some plans also have a waiting period of 6 to 12 months before they cover major work, so a brand-new plan may not pay right away.
Root Canal Cost With Delta Dental, Cigna, and Blue Cross Blue Shield
People search for specific insurers, so here is the honest version. There is no single price for any carrier, because each one offers many plan types. A Delta Dental, Cigna, or Blue Cross Blue Shield plan can be a PPO or a DHMO, with different deductibles, annual maximums, and networks, so two people with the same insurer can pay very different amounts.
What is consistent is the pattern: the major carriers generally cover root canals at 50% to 80% as basic or major restorative care, after your deductible and up to your annual maximum. Delta Dental, for example, publishes typical out-of-network fee ranges of about $620 to $1,100 for a front tooth, $720 to $1,300 for a premolar, and $890 to $1,500 for a molar, then pays its share of that. The reliable move is not to trust a generic number online but to request a written predetermination from your own plan, which we explain next.
The ADA Codes That Get You an Honest Estimate
This is the step almost nobody takes, and it is the one that protects you. Every dental procedure has a standard ADA code, and using them turns a vague quote into a firm one.
Root canals are billed as D3310 for a front tooth, D3320 for a premolar, and D3330 for a molar. The crown is separate, often D2740 for an all-ceramic crown. Ask the dental office for a dated, itemized estimate listing every code that applies, including the exam, X-rays, the root canal, any build-up or post, and the crown. Then ask your insurer for a written predetermination using those exact codes. That document tells you your remaining deductible, your coverage percentage, how much of your annual maximum is left, and the plan’s estimated payment for each item. With that in hand, you know your real number before you sit in the chair, not after.
How to Lower Your Root Canal Cost
There are several honest ways to bring the bill down, and they stack.
- Stay in-network. Your share is a percentage of the discounted fee, so in-network is almost always cheaper.
- Use FSA or HSA dollars. A medically necessary root canal is an eligible expense, so paying with pre-tax money effectively cuts the cost by your tax rate, often 22% to 32%.
- Ask about a dental savings plan. If you have no insurance, these membership plans cut 10% to 25% off, with no annual maximum or waiting period.
- Check a dental school clinic. Supervised student clinics often charge 30% to 50% less than private practice.
- Time it across two benefit years. If it is not an emergency and your annual maximum is nearly used, schedule the root canal in December and the crown in January. That spreads the two big costs across two annual maximums and can save you hundreds.
Root Canal vs. Extraction: Which Saves Money?
Pulling the tooth looks cheaper today, and a simple extraction often is. But it rarely ends there. An empty space usually needs replacing with an implant or bridge, which commonly costs more than the root canal would have, and leaving the gap can cause neighboring teeth to shift and the jawbone to shrink.
That is why dentists generally recommend saving a tooth that can be saved. A root canal keeps your natural tooth, which is usually the lower lifetime cost. If you are weighing the two, it helps to compare the all-in numbers, not just today’s price. Our guide on tooth extraction cost without insurance walks through the removal side of that decision.
Is a Root Canal Painful? And Other Common Questions
Cost is only half of what people worry about, so here are quick, honest answers to the medical questions that come up most. The short version: modern root canals are far less dramatic than their reputation.
On a scale of 1 to 10, most patients rate the procedure itself around a 1 to 3, about the same as getting a filling, because the area is fully numbed. The pain people associate with root canals comes from the infection beforehand, not the treatment. Afterward, expect mild soreness for a day or two that over-the-counter pain relievers handle easily. We cover longevity, crowns, and the myths in the FAQs below.
The Honest Read
After years working with out-of-pocket healthcare costs, the pattern I see with root canals is always the same: the surprise is never the root canal, it is the crown and the annual maximum. People hear “insurance covers 70%” and assume they are mostly covered, then get a second bill for the crown and discover their yearly cap is spent. The fix is simple and it is free: get a written predetermination with the ADA codes before you agree to anything.
The other thing worth saying plainly is that a root canal is worth doing. The scary claims you may have seen online, that root canals cause disease or that dentists secretly oppose them, come from research that was discredited almost a century ago. Major dental organizations confirm the procedure is safe. The real health risk is leaving an infected tooth untreated. So budget for the crown, time your benefits well, and save the tooth.
Conclusion
Your root canal cost with insurance is usually $200 to $900 out of pocket for the procedure, and about $600 to $1,800 once you add the crown that most back teeth need. The variables that decide your number are the tooth, your coverage percentage, your annual maximum, and your network. Do three things and you will not be surprised: ask for an itemized estimate with ADA codes, request a written predetermination from your insurer, and consider timing the root canal and crown across two benefit years if your maximum is running low. Save the tooth, plan for the crown, and use your benefits wisely.
FAQs
How much is a root canal if you have insurance?
With insurance, you usually pay about $200 to $900 out of pocket for the root canal itself, because most plans cover 50% to 80% after your deductible. Adding the crown that most back teeth need brings the combined out-of-pocket to roughly $600 to $1,800. Your exact cost depends on the tooth, your annual maximum, and whether you are in-network.
How much does a molar root canal cost with insurance?
A molar root canal is billed at about $1,000 to $1,800 because molars have three or four canals. With 50% to 80% coverage, you typically pay about $250 to $900 out of pocket for the procedure, plus your deductible. Most molars also need a crown afterward, which is a separate cost.
Why is my root canal $3,000?
A $3,000 quote almost always includes the crown, not just the root canal. A molar root canal plus a crown, sometimes with a build-up or post, commonly totals $1,600 to $3,200 without insurance and can top $4,000 with premium materials and a specialist. The root canal alone is usually far less.
What is the root canal and crown cost with insurance?
Together, a root canal and crown usually cost about $600 to $1,800 out of pocket with insurance. The root canal is often covered at 50% to 80%, and the crown is usually covered separately at around 50%. Watch your annual maximum, because both procedures count against it and can use it up.
Does Delta Dental cover root canals?
Yes. Delta Dental plans generally cover root canals at 50% to 80% as basic or major restorative care, after your deductible and up to your annual maximum. The exact amount depends on whether you have a PPO or DHMO plan and whether your dentist is in-network. Request a predetermination for your specific plan.
How much is a root canal with Cigna or Blue Cross Blue Shield?
There is no single price, because Cigna and Blue Cross Blue Shield each offer many plan types with different deductibles, networks, and maximums. As a rule, they cover root canals at 50% to 80% after your deductible. Two people with the same insurer can pay different amounts, so get a written predetermination using the ADA codes.
How painful is a root canal on a scale of 1 to 10?
Most patients rate the procedure itself around a 1 to 3, similar to getting a filling, because the tooth is fully numbed. The intense pain people fear actually comes from the infection before treatment, which the root canal relieves. Expect only mild soreness for a day or two afterward.
Do I need a crown after a root canal?
Usually yes, especially on back teeth. About 90% of molars and premolars need a crown to keep the treated tooth from cracking, since it becomes brittle after the pulp is removed. Some front teeth can be restored with just a filling. Your dentist will advise based on the tooth.
Which tooth is hardest to root canal?
Molars are the hardest, particularly upper molars. They have three or four canals, sit at the back where they are harder to reach, and often have curved roots. That complexity is why molars cost more and are more often referred to an endodontist.
How many years does a root canal last?
A well-done root canal can last a lifetime, especially once a crown protects the tooth. Success rates are high, and millions of teeth are saved this way each year. Longevity depends on placing the crown promptly and keeping up with brushing, flossing, and regular checkups.
What is the downside of a root canal?
The main downsides are the cost, the fact that the tooth becomes more brittle and usually needs a crown, and a small chance the treatment fails or needs redoing. Even so, a root canal is generally cheaper over time than pulling the tooth and replacing it. The alternative, an untreated infection, is worse.
Can a tooth still rot after a root canal?
Yes. A root canal removes the nerve, so you will not feel new decay, but the remaining tooth and the edges of the crown can still develop cavities. Because there is no pain to warn you, regular checkups matter even more. Good brushing and flossing keep the treated tooth healthy.
Why are dentists against root canals?
They are not. The idea that dentists oppose root canals comes from a debunked theory from the 1920s that linked treated teeth to disease, which was discredited decades ago and revived by a misleading documentary. Major dental organizations confirm root canals are safe, and the real threat is the untreated infection, not the treatment.
What does a dying tooth nerve feel like?
A dying nerve often causes lingering sensitivity to hot or cold that does not fade, throbbing or spontaneous pain, and sometimes pain that later goes numb. The tooth may darken, and a small pimple-like bump can appear on the gum. Any of these is a reason to see a dentist promptly.
What is the 3-3-3 rule for root canals?
There is no widely recognized “3-3-3 rule” for root canals in dentistry, so be cautious about sources that state one as fact. What matters for recovery is straightforward: expect mild soreness for a few days, avoid chewing on the treated side until the permanent crown is placed, and call your dentist if severe pain lasts more than a few days.
