A Mother Is Staring at a $3,600 Root Canal Bill — and Medicare at 65 Usually Won’t Cover It

A $3,600 root canal is already beyond the reach of many Americans, and qualifying for Medicare at 65 does not usually solve that problem the way people often expect.

Bloomberg reported that a 44-year-old Texas mother needed a root canal priced at $3,600, but her health plan excluded dental care and she could not afford the procedure. Her case raises a larger question for people nearing retirement: would Medicare pay that bill?

Now imagine a woman only a few months away from 65 facing the same estimate. She may think about waiting for Medicare to begin, assuming it will help with the cost. In most cases, unless a limited medical exception applies, Original Medicare would still leave her with the full bill.

That estimate is higher than a month’s average Social Security retirement benefit. The agency said the average retired worker’s monthly payment was $2,071 for January 2026 after the cost-of-living adjustment. Dental coverage through a retiree plan or a working spouse’s employer may help. Anyone moving to Original Medicare should find out what dental protection they will keep before delaying treatment.

What Original Medicare Pays for a Root Canal: Usually Nothing

Medicare’s own coverage information says it generally does not pay for routine cleanings, fillings, tooth extractions, dentures or implants, and beneficiaries are responsible for the full cost. Root canals are part of that excluded category. A Medigap policy does not change that. Supplement plans only help pay the share of services Medicare already covers, so if Medicare pays nothing, the supplement pays nothing as well.

The exceptions are narrow. Medicare may pay for dental work that is necessary for a covered medical treatment, such as:

• An oral exam and dental treatment before a heart valve replacement or an organ, kidney or bone marrow transplant
• A procedure, like an extraction, to clear a mouth infection before chemotherapy
• Treatment for problems that arise during head and neck cancer treatment
• Exams and infection treatment before and during dialysis for end-stage renal disease

When dental care qualifies under Part B, she generally owes 20% of the Medicare-approved amount after the $283 annual deductible in 2026. A hospital outpatient visit can also include a facility copayment, and covered inpatient care follows Part A rules. If an infected tooth would threaten the success of a covered valve replacement, treatment to clear that infection may qualify. Pain by itself does not establish that medical connection.

Medicare Advantage Dental Benefits Can Have Caps, Networks and Waiting Periods

Dental coverage under Medicare Advantage varies from plan to plan. Some plans cover only preventive services, while others help pay for root canals, crowns and other major work. Annual limits, coinsurance and dentist networks can leave a large remaining balance. It is also important to check when coverage starts and whether any waiting period applies to the specific dental benefit offered.

Dental coverage should be part of the Medicare decision alongside doctor networks, prescription coverage, prior authorization and medical costs. Before choosing a plan because of its advertised dental allowance, find out what it would actually pay toward treatment.

Example Math: How a $1,500 Allowance Still Leaves a $2,100 Balance

Suppose an example Advantage plan covers the root canal, the dentist is in network, and $3,600 is the plan’s allowed amount. There is no dental deductible, the patient pays 50% coinsurance, and the plan will not pay more than $1,500 in a year. Half the charge would normally be $1,800, but the annual maximum limits the plan payment to $1,500.

Add an optional dental rider costing about $40 a month, and the best-case annual total rises to $2,580 once premiums are included. Even in that stronger scenario, she still pays most of the bill.

Waiting also carries a cost. An infection left untreated for months can turn a tooth that might have been saved into an extraction and replacement, which is even more expensive and still subject to the same annual cap. For most people in this position, waiting for Medicare saves little and can put the tooth at greater risk.

Get the Treatment Plan in Writing Before Scheduling Care

1. Ask the dentist for a written treatment plan. It should list each procedure code and the fee for each one. Without codes, no insurer can give a meaningful coverage answer.
2. Get a written estimate from any plan you are considering. Ask for the annual maximum, how much is left, the coinsurance rate for major services, any waiting period, and whether the dentist is in network. Do this before enrolling, because dental benefits can vary widely from plan to plan.
3. Check for any medical connection before assuming coverage. If she is preparing for a valve replacement, transplant, cancer treatment or dialysis, have her physician and dentist coordinate care and document why the dental work is needed for that covered treatment to succeed. Ask the billing office to confirm whether Medicare’s requirements are met and to estimate her share. A physician’s note alone does not guarantee payment.

Before she waits for Medicare, she needs to know whether turning 65 will change who pays or simply leave her with the same bill after more months of pain.
