In October 2016, NPR Shots published a report on a gap that catches many Americans by surprise: reaching Medicare age does not mean reaching dental coverage. The piece featured Dr. Michael Helgeson, then chief executive of Apple Tree Dental, a Minneapolis-based nonprofit operating multiple Centers for Dental Health and mobile dental units for adults without standard coverage. The structural problem Helgeson described was not a policy oversight or a benefit that was promised and cut. Medicare was designed in 1965 without a dental benefit. The federal law governing the program has not added one in the six decades since. That is the design.
The coverage gap is substantial. A 2021 brief from KFF, titled "Medicare and Dental Coverage: A Closer Look," found that nearly half of Medicare beneficiaries, 47 percent, or 24 million people, had no dental coverage as of 2019. That figure reflects the program's original architecture. The brief documents a structural feature of federal law, not a recent policy shift or a gap that is expected to close. (Sources below.)
Medicare was written without a dental benefit in 1965. Congress has not added one. Six decades later, the exclusion is still in the law.
What's worth knowing
01 What Original Medicare actually covers (the 1965 exclusion)
Medicare's exclusion of routine dental care is in the original legislation. Section 1862(a)(12) of the Social Security Act, enacted in 1965, specifically excludes items and services in connection with the care, treatment, filling, removal, or replacement of teeth. That statutory language has not been amended to add a routine dental benefit. CMS, the Centers for Medicare and Medicaid Services, currently administers Medicare coverage for approximately 65 million beneficiaries. None of them receive routine cleanings, X-rays, fillings, extractions, crowns, or implants under Original Medicare, regardless of income, health status, or how long they have contributed to the program. The program has now run for 60 years with this design intact.
02 The narrow medically-necessary exception
There is one exception, and it is narrow. Medicare Part A, the hospital insurance portion, may cover certain dental services when they are medically necessary as part of another covered hospital procedure. CMS guidance cites examples such as a dental clearance required before an organ transplant or before cardiac surgery: in those cases, the dental service may be covered as part of the hospital procedure's related coverage, not as standalone dental care. The key is that the dental service must be directly tied to a covered inpatient hospital procedure. A patient whose dental needs are not connected to a covered hospital procedure will not find coverage under this exception. The exception has not been expanded in the 60 years since the statute was written. It almost never applies to routine adult dental care.
03 Medicare Advantage dental in practice
Medicare Advantage plans, the privately administered alternative under Part C, are permitted to offer dental benefits that Original Medicare does not include, and most plans marketed to seniors now do. According to KFF's 2021 analysis, roughly 94 percent of Medicare Advantage enrollees in individual plans had access to some dental coverage. In practice, plans distinguish between preventive services, typically cleanings and X-rays, and more extensive services. Preventive services are usually covered at low or no cost. More extensive services are subject to annual benefit caps and coinsurance. The average annual limit on more extensive dental benefits among plans offering them was approximately $1,300. The most common coinsurance rate for more extensive services was 50 percent.
04 The out-of-pocket reality
What Medicare beneficiaries actually pay for dental reflects the coverage gap. The KFF 2021 brief, drawing on 2018 data, found that among beneficiaries who used any dental services that year, average out-of-pocket spending was $874. That average includes people with Medicare Advantage dental coverage and people paying entirely on their own. The distribution is steep: 20 percent of dental users spent more than $1,000 out of pocket; 10 percent spent more than $2,000. Lower-income beneficiaries had both less coverage and less capacity to absorb those costs. Among Medicare beneficiaries with annual incomes below $10,000, 73 percent did not see a dentist in 2018, the highest non-utilization rate of any income group in the brief.
05 What aging into Medicare looks like as a dental consumer
Original Medicare covers no routine dental. A Medigap supplemental policy does not generally add dental coverage. The Medicare Advantage route offers the most practical path to partial dental coverage within the Medicare system, but plans vary significantly in caps, coinsurance, in-network requirements, and what qualifies as preventive versus more extensive care. Comparing plans by county during open enrollment is the standard approach. Outside the Medicare structure, community health centers, federally qualified health centers that operate on a sliding-scale fee basis and serve patients regardless of ability to pay, and dental school clinics, which provide care at reduced fees with longer appointment times, are the primary structural alternatives. The KFF brief found that 47 percent of Medicare beneficiaries, 24 million people, had no dental coverage. These structural alternatives exist for that population.
If you are looking for a dental office to reach out when they open
If you are navigating Medicare's dental gap and trying to figure out next steps, instead of comparing Medicare Advantage plans one by one to find which include dental and what their caps look like, you can submit your information once on toothhurt.com. A participating dental office in your area can reach out during business hours. toothhurt.com is operated by Tooth Hurt LLC, an independent marketing service, not a dental practice. Submitting does not guarantee an appointment.
In plain words
Original Medicare, Parts A and B, does not cover routine dental care. The exclusion is in federal law since 1965 (Section 1862(a)(12) of the Social Security Act) and has not been changed. No routine cleanings, X-rays, fillings, extractions, crowns, or implants are covered under Original Medicare, regardless of how long someone has paid into the program.
Medicare Advantage plans can include dental coverage and most now offer some. The coverage is partial: preventive care is typically covered at low or no cost, more extensive work faces an annual cap (around $1,300 on average) and 50 percent coinsurance. Medigap supplemental policies do not generally cover dental. The structural alternatives outside Medicare, community health centers and dental school clinics, serve the population that Medicare dental coverage does not reach.

Common questions
Is toothhurt.com a dental directory?
No. toothhurt.com is not a directory of dental practices. It does not present a list of offices to compare, rate, or contact individually. The product is structured around a single intake form: one submission, and a participating dental office in your area can reach out during business hours. toothhurt.com is operated by Tooth Hurt LLC, an independent marketing service, not a dental practice, and does not provide dental care, diagnosis, or treatment.
Does Medicare cover dental cleanings?
Original Medicare, Parts A and B, does not cover routine dental cleanings, X-rays, fillings, extractions, crowns, or implants. There is no preventive dental benefit under Original Medicare. Medicare Advantage plans may include a preventive dental benefit, but coverage depends on the specific plan and varies by carrier and county.
Does Medicare Advantage cover everything dental?
Medicare Advantage plans can offer dental benefits, and most do. Coverage is partial and capped. Preventive services such as cleanings and X-rays are often covered at low or no cost. More extensive services are typically subject to coinsurance and an annual benefit cap. According to KFF's 2021 analysis, the average annual limit on more extensive dental benefits among Medicare Advantage plans offering them was approximately $1,300, and the most common coinsurance rate for more extensive services was 50 percent.
If Medicare doesn't cover dental, what are seniors actually using?
The options seniors use include Medicare Advantage plans for those whose plan includes dental coverage, Medicaid for dual-eligible enrollees who qualify for both Medicare and Medicaid, direct out-of-pocket payment, and structural alternatives outside coverage. Community health centers, federally qualified health centers, operate on a sliding-scale fee basis and accept Medicaid. Dental school clinics provide care at reduced fees with longer appointment times. These are structural categories, not ranked recommendations.
