Does dental insurance cover root canals?
Usually covered
Root canals are standard restorative dental care and most plans cover them — as a basic or major service, paying a share after any deductible up to your annual maximum.
- Covered when You have a plan with basic and/or major services and have met any deductible or waiting period — the standard covered case.
- Not when Your plan is preventive-only (cleanings and exams) with no basic or major restorative benefit.
- Not when You've already exhausted the annual maximum on other treatment this year.

A root canal treats infection or damage inside a tooth, so it's clearly medical rather than cosmetic dental work. Nearly all dental plans that offer more than preventive-only coverage include endodontic treatment like root canals.
Plans differ on the tier. Some classify root canals as a basic service (often reimbursed at a higher percentage), others as a major service (reimbursed at a lower percentage and sometimes subject to a waiting period). Either way you'll usually owe your deductible plus coinsurance, and the payout counts against the annual maximum.
A root canal is also frequently followed by a crown to protect the tooth, which is billed and covered separately under the crown rules. Your plan's schedule of benefits shows which tier applies and what percentage it pays.
What people typically pay
With a plan that covers basic or major services, people generally pay their deductible plus coinsurance, up to the annual maximum, with the exact share varying widely by plan. A following crown adds its own share on top.
Without coverage, out-of-pocket costs vary widely by tooth, region, and provider — molars tend to be more complex and cost more, and adding a crown increases the total further.
Costs vary widely by tooth, region, whether a specialist (endodontist) does the work, and your plan's negotiated fees. Confirm specifics with your dentist and insurer.
How to actually get it covered
Have the dentist confirm the diagnosis and note whether a root canal is recommended, plus whether a crown will follow — get it in writing.
Call your dental plan or check the member portal to confirm which tier root canals fall under, the coinsurance percentage, any deductible, waiting period, and how much annual maximum remains.
Ask the dentist's office to submit a predetermination (pre-treatment estimate) to your insurer so you see the plan's payment and your share before work begins.
Verify the treating dentist or endodontist is in-network to get the negotiated rate and higher reimbursement.
Complete the root canal, then schedule the crown and confirm separately how the crown tier and any remaining maximum apply.
If the claim is denied or underpaid, request the explanation of benefits, ask the office to resubmit with clinical notes and X-rays, and file an appeal if the treatment was medically warranted.
Common questions
Is a root canal usually covered as a basic or a major service?
It depends entirely on your plan's schedule of benefits. Some plans list endodontic treatment like root canals as a basic service, often reimbursed at a higher percentage, while others put it in the major tier reimbursed at a lower rate. Check the schedule or call the number on your card to confirm which tier and percentage apply before treatment.
Will I have to wait before my plan pays for a root canal?
Sometimes. Some plans — especially those that classify root canals as a major service — attach a waiting period before that benefit becomes active. HealthCare.gov specifically warns that stand-alone dental plans can have waiting periods before they cover services for adults, so check with the insurer for details before enrolling. Your plan documents spell out the exact waiting period, if any.
Does the crown that follows a root canal get covered separately?
Yes. The root canal treats the inside of the tooth, and the crown that caps it afterward is billed and covered under separate crown rules — often the major-service tier with its own percentage and possible waiting period. Both procedures draw down the same annual maximum, so a root canal plus crown can use up a large chunk of your yearly benefit.
What if my annual maximum is already used up when I need the root canal?
Once you hit your plan's annual maximum, it stops paying for the rest of the benefit year and you cover the full cost yourself. If the tooth can safely wait, some people schedule the root canal after the plan year resets so the maximum is fresh again. If it can't wait, ask your dentist about a payment plan or splitting the root canal and crown across two benefit years.
Does it matter whether the root canal is on a front tooth or a molar?
It can affect the price but not usually whether it's covered. Molars have more roots and are more complex, so they generally cost more and your coinsurance dollar amount will be higher even at the same percentage. A predetermination of benefits will show what your plan pays for the specific tooth.
