Quick answer
How much is a root canal with insurance?
With a PPO plan, a root canal typically runs about $150 to $600 out of pocket once the plan pays its 50% to 80% share and your deductible is met. The exact figure depends on your remaining annual maximum and whether a crown is also needed. Any waiting period must have cleared. Figures are approximate and illustrative.
What you pay
How much is a root canal after the plan pays?
After a PPO plan pays its typical 50% to 80%, a root canal usually costs roughly $150 to $600 out of pocket for the procedure itself. Where you land inside that band depends on the tooth treated, your coinsurance percentage, whether your deductible is already met, and how much of your annual maximum remains.
Think of insurance as a discount engine, not a flat price tag. The plan pays a set percentage of an allowed amount, then you cover the rest. So the headline "root canals cost a lot" softens fast once coverage applies, but only if you understand exactly which numbers feed the formula.
The real math
Gross cost, then what you pay
Take the gross fee, subtract what your plan pays, and what remains is yours. A $1,200 molar root canal with a plan paying 70% leaves about $360, plus any unmet deductible. Front teeth cost less gross, so your share is smaller; molars cost most because they carry more canals.
| Line item | Detail | Amount |
|---|---|---|
| Gross cost of procedure | Molar, three+ canals | $1,200 |
| Plan pays | 70% of allowed amount | − $840 |
| Deductible (if unmet) | Applied before coinsurance | − varies |
| You pay | Remaining balance | ~$360 |
| Tooth | Gross | Plan pays 70% | Your cost |
|---|---|---|---|
| Front tooth | $900 | − $630 | ~$270 |
| Premolar | $1,050 | − $735 | ~$315 |
| Molar | $1,200 | − $840 | ~$360 |
Watch the annual maximum. A crown almost always follows a root canal. If the crown is restored in the same benefit year, the procedure plus crown can together approach or exceed your annual maximum, at which point the plan stops paying and the rest of the crown is fully on you. Splitting them across two plan years can keep more of your benefit intact.
The five levers
What affects your out-of-pocket
Five plan settings decide your final number: the deductible you pay first, the coinsurance percentage the plan covers, the annual maximum that caps total payouts, any waiting period before coverage starts, and whether your dentist is in-network. Change one and your out-of-pocket can swing by hundreds of dollars.
- Deductible. A fixed amount you pay before coinsurance kicks in, often $50 to $150. If it is unmet, add it on top of your calculated share for this visit.
- Coinsurance percentage. The slice the plan covers for this service, typically 50% to 80% for root canals. A plan at 80% leaves you far less than one at 50% on the same fee.
- Annual maximum. The most the plan will pay you in a benefit year, commonly $1,000 to $2,500. Once reached, you pay full price for anything further that year, crown included.
- Waiting period. Some plans delay major-service coverage 6 to 12 months. A great percentage is worthless on a tooth that hurts today if the wait has not cleared.
- In-network vs out-of-network. In-network dentists accept the plan's negotiated rate, which is lower than the cash fee. Out-of-network, you can owe the gap above the allowed amount. Find an in-network PPO dentist
Plan comparison
Plans that pay the most toward a root canal
The plans that minimize your root-canal bill combine a healthy major-service percentage, a workable annual maximum, and short or waived waiting periods. Positioning differs by carrier, so the right pick depends on whether you need treatment soon or are planning ahead for a crown the following year.

- Positioned for fast activation
- Solid preventive base
- Major-service benefits move toward endodontic care without a long delay

Ameritas PrimeStar
- Pays about 20% on major work from day one
- No waiting period
- Percentage often rises in later plan years (verify current terms)
- See Ameritas PrimeStar
Humana Extend 5000
- Pays about 50% on major work after a 6-month wait
- Higher annual ceiling, around $5,000
- Useful when a root canal and crown land close together
- Compare all PPO plans
Verify current plan details. Carriers adjust percentages, maximums, deductibles, and waiting periods, and availability varies by state. Confirm the exact terms on each plan page before enrolling rather than relying on positioning alone.
Cut it further
Lower your cost even further
Insurance covers the percentage; three more moves shrink the rest. Finance the remaining balance over time, pay it with pre-tax FSA or HSA dollars, and time the crown across two plan years so a single annual maximum never has to absorb both the root canal and the crown at once.
Finance the leftover balance
Whatever your plan does not pay, you do not have to settle in one lump. A 0% or no-credit plan can spread the remaining few hundred dollars into manageable monthly payments. See root canal financing options
Pay with FSA or HSA dollars
A root canal is an eligible expense. Using pre-tax money for your out-of-pocket share is effectively a 20% to 35% discount depending on your tax bracket, stacked on top of what insurance already paid.
Time the crown across plan years
If your annual maximum is tight, schedule the root canal late in one benefit year and the crown early in the next. Each procedure then draws on a fresh maximum, so neither gets cut off mid-payout.
