Medicare does not cover root canals
Original Medicare (Parts A and B) does not pay for root canals, crowns, fillings, or most other dental work. This is true whether the tooth is causing you pain, has an infection, or is about to fail. The only dental services Medicare covers are extractions (pulling teeth) that are medically necessary — meaning the tooth is causing a serious infection or other health problem that needs hospital treatment.
If you need a root canal, you will pay the full cost out of pocket unless you have a separate dental plan. The cost varies widely by location and dentist, but a root canal typically runs between $800 and $1,500 per tooth, plus the cost of a crown to seal it afterward.
Key Takeaways
- Medicare Part A and Part B do not cover root canals, crowns, fillings, or routine dental care under any circumstances.
- Medicare covers tooth extraction only when the tooth is causing a serious infection that requires hospital-level treatment.
- Medicare Advantage plans (Part C) sometimes include dental coverage, but you must check your specific plan's details before assuming it covers root canals.
- Standalone dental plans, Medicaid (if you may have access to), or dental discount programs are your main options to reduce the cost of a root canal.
- Delaying a root canal can lead to tooth loss, bone damage, and infection spreading to other parts of your body.
Why Medicare excludes dental work
Medicare was designed to cover medical care — hospital stays, doctor visits, prescription drugs — not dental or vision care. Congress made this choice when Medicare began in 1965, and the exclusion has remained in place for nearly 60 years. The reasoning was that dental care is separate from medical care and should be handled through private dental plans or out-of-pocket payment.
This gap affects millions of older adults. Many people who had dental coverage through an employer lose it when they retire, and Medicare does not fill that gap. The result is that many seniors either skip dental care or pay for it themselves.
When Medicare might cover tooth-related costs
Medicare will pay for hospital or emergency room treatment if a dental infection becomes serious enough to require medical intervention. For example, if an untreated root canal leads to an abscess that spreads to your jaw or sinuses, Medicare covers the hospital stay and antibiotics. But Medicare is not paying for the root canal itself — it is paying for the medical emergency that resulted from not having one.
Medicare also covers oral surgery performed by a hospital dentist if the surgery is medically necessary and done in a hospital setting. This is rare and usually applies only to complex extractions or jaw reconstruction after injury or cancer treatment.
Medicare Advantage plans and dental coverage
Some Medicare Advantage plans (Part C) include dental coverage as an added benefit. However, coverage varies widely. Some plans cover cleanings and X-rays only. Others cover basic procedures like fillings and extractions but exclude root canals. A few plans cover root canals, but usually with limits — such as covering only one root canal per year or requiring you to pay a percentage of the cost.
If you have a Medicare Advantage plan, call the plan directly and ask whether root canals are covered. Do not assume they are, and do not assume that because your plan covers cleanings it also covers root canals. Ask for the specific coverage limits in writing before you schedule the procedure.
Standalone dental plans and other payment options
If you do not have dental coverage through Medicare Advantage, you have several options to reduce the cost of a root canal.
Standalone dental plans are insurance policies you buy separately. They typically cost $100 to $200 per month and cover a portion of root canals, crowns, and other procedures. Most have a waiting period of 6 to 12 months before they cover major work like root canals, so they are most useful if you plan ahead. You can buy a standalone plan through private insurers, and some are sold through AARP.
Medicaid covers dental work in some states, including root canals. may be able to access depends on your income and assets. If you may have access to for both Medicare and Medicaid (called "dual may be able to access"), Medicaid may cover the root canal. Contact your state Medicaid office to find out whether dental coverage is available and whether you may have access to.
Dental discount plans are not insurance — they are membership programs that give you a discount (usually 10 to 60 percent) at participating dentists. They cost $80 to $200 per year and have no waiting period. A root canal that normally costs $1,200 might cost $600 to $800 with a discount plan. These work best if you have a participating dentist nearby.
Community health centers and dental schools offer low-cost or sliding-scale root canals. Dental schools charge less because students perform the work under supervision. Community health centers base fees on your income. Search for "federally may have access to health center" or "dental school" in your area.
What happens if you delay a root canal
A tooth that needs a root canal has an infected or dying nerve. The infection does not go away on its own. If you delay treatment, the infection can spread to the bone around the tooth, causing bone loss and permanent damage. In some cases, the infection spreads to the sinuses, jaw, or bloodstream, which can become life-threatening.
Delaying also makes the tooth harder to save. A tooth that can be treated with a root canal today may need extraction in six months if the infection worsens. Once a tooth is extracted, you face the cost of a bridge or implant to replace it — both of which are also not covered by Medicare and cost $1,000 to $6,000 or more.
How to find a dentist and negotiate costs
If you are paying out of pocket, call several dentists and ask for a price quote for a root canal on a specific tooth. Prices vary significantly, and some dentists will negotiate, especially if you are paying cash. Ask whether the quote includes the crown, which is usually necessary after a root canal.
Ask whether the dentist offers a payment plan. Many dental offices let you pay in installments over several months with no interest. Some offer discounts if you pay in full upfront.
If cost is a barrier, ask the dentist whether a general dentist or an endodontist (a specialist) is doing the work. Specialists charge more, but for straightforward cases, a general dentist may be able to do the root canal at a lower cost.
Frequently Asked Questions
Does Medicare Part D cover the cost of antibiotics for a tooth infection?
Yes. If you have a tooth infection and your doctor prescribes antibiotics, Medicare Part D (prescription drug coverage) covers the medication. However, Part D does not cover the root canal or extraction that caused the infection. You still need to pay for the dental work itself.
If I have a Medicare Advantage plan with dental coverage, will it cover a root canal I need right now?
It depends on your specific plan. Call your plan's customer service number and ask whether root canals are covered, what the waiting period is, and whether there are annual limits. Have your plan documents handy when you call. If the plan does cover it, ask whether you need prior approval before scheduling the procedure.
Can I get a root canal at a hospital instead of a dental office to make Medicare pay?
No. Medicare does not cover root canals in a hospital setting any more than it covers them in a dental office. The only exception is if the root canal is part of a larger medically necessary surgery, such as jaw reconstruction after cancer treatment.
What if I cannot afford a root canal and the tooth gets infected?
Go to an emergency room or urgent care if you develop severe pain, fever, or facial swelling — these are signs the infection is spreading. Medicare will cover the emergency treatment. However, the long-term solution is extraction or root canal, both of which you will need to pay for separately. Delaying treatment makes the problem worse and more expensive.
Are there any states where Medicare covers dental work?
No. Medicare is a federal program with the same rules in all states. However, some states offer more generous Medicaid dental coverage than others. If you think you might may have access to for Medicaid based on your income, contact your state Medicaid office to ask about dental coverage.
