Original Medicare (Parts A and B) does not cover routine dental care. No cleaning, no fillings, no extractions, no dentures, no implants. If you want dental coverage through Medicare, your main option is a Medicare Advantage plan (Part C), which frequently includes dental benefits that Original Medicare explicitly excludes.
What Original Medicare Excludes
Medicare Part A and Part B were designed without dental coverage, and that gap has never been closed. The exclusion is broad: routine cleanings, fillings, tooth extractions, dentures, implants, root canals, and gum disease treatment are all out. If you have only Original Medicare, you pay 100% of these costs out of pocket.
There are a handful of narrow medical exceptions. Medicare Part A will cover dental services that are an integral part of another covered procedure. The clearest example is a dental exam required before a kidney transplant. In that case, the exam isn’t being treated as dental care. It’s part of the surgical workup to identify infections that could jeopardize the transplant. Similarly, if you’re hospitalized and need emergency dental work to treat a medical condition (like a jaw fracture), Part A may cover the hospital stay, though it still won’t pay for the dental care itself. These exceptions are rare and situation-specific.
For the small number of dental services Part B does cover (again, only when tied to a medical necessity), you pay 20% of the Medicare-approved amount after meeting your Part B deductible.
Medicare Advantage: The Primary Source of Dental Coverage
Medicare Advantage plans, sold by private insurers, are required to cover everything Original Medicare covers. But most also bundle in extra benefits, and dental is one of the most common additions. The specifics vary widely from plan to plan and region to region, so the details of your coverage depend entirely on which plan you choose.
Most Medicare Advantage dental benefits fall into two tiers: preventive and comprehensive. Preventive benefits typically cover oral exams, cleanings, and X-rays. About 64% of enrollees in plans offering these preventive services pay nothing out of pocket for them, though many of these plans cap how much preventive care they’ll cover each year.
Comprehensive benefits go further, covering fillings, extractions, root canals, crowns, periodontal treatment, and sometimes dentures. These services come with higher cost sharing. The most common coinsurance rate across major service categories is 50%, meaning you’d pay half the cost for things like root canals, gum treatments, and prosthetics. For dentures specifically, cost sharing ranges from $0 to a $500 copay, or coinsurance of 50% to 70% depending on the plan.
Annual Limits on Dental Benefits
One important detail many people miss: even when a Medicare Advantage plan covers dental, it often caps the total amount it will pay in a given year. For preventive-only dental benefits, there’s usually no annual cap, but when one exists, common limits are $150, $250, $300, or $500. For comprehensive dental coverage, over half of plans don’t impose an annual limit. Among those that do, maximums range from under $1,000 to $2,000 or more.
These caps matter most if you need expensive work. A single dental implant can cost several thousand dollars. If your plan’s annual maximum is $1,000, you’re covering the rest yourself. Before enrolling in any Medicare Advantage plan for its dental benefits, check three things: what services are covered, what your coinsurance or copay will be, and whether there’s an annual dollar limit.
Medigap Plans Don’t Include Dental
If you stick with Original Medicare and buy a Medigap (Medicare Supplement) policy to reduce your out-of-pocket costs, you still won’t get dental coverage. Medigap plans are standardized by the federal government, and none of the standard plan types (A through N) include dental, vision, or hearing benefits. Medigap helps pay for the gaps in Original Medicare, like deductibles and coinsurance on covered services. Since dental isn’t a covered service under Original Medicare, there’s no gap for Medigap to fill.
Standalone Dental Insurance
If you prefer Original Medicare over Medicare Advantage but still want dental coverage, you can buy a separate dental insurance policy on the private market. These standalone plans aren’t connected to Medicare at all. They work like any individual dental insurance: you pay a monthly premium and get coverage for a defined set of services, usually with waiting periods for major procedures and annual benefit caps typically ranging from $1,000 to $2,000.
Dental discount plans are another option. These aren’t insurance. You pay an annual membership fee and get access to reduced rates at participating dentists, usually 10% to 60% off standard prices. There are no claims to file and no annual maximums, but you’re still paying out of pocket at the discounted rate.
Coverage for People With Both Medicare and Medicaid
If you qualify for both Medicare and Medicaid (sometimes called “dual eligibility”), your dental options may be better than you think. Medicaid programs in most states cover at least some dental services for adults, though the extent varies significantly. Some states offer comprehensive dental care through Medicaid, while others limit coverage to emergency extractions.
Dual Special Needs Plans (D-SNPs) are a type of Medicare Advantage plan designed specifically for people with both Medicare and Medicaid. These plans coordinate benefits between the two programs, which can simplify coverage and reduce out-of-pocket costs. Most health care costs, including dental in many cases, are covered or significantly reduced for dual-eligible individuals. Your state Medicaid office can clarify exactly which dental services are included in your state.
Comparing Your Options
- Original Medicare alone: No routine dental coverage. You pay everything out of pocket unless a dental service is medically necessary as part of a covered procedure.
- Original Medicare plus Medigap: Still no dental. Medigap explicitly excludes it.
- Original Medicare plus standalone dental insurance: You get dental coverage through a separate private policy, with its own premiums, copays, and annual limits.
- Medicare Advantage (Part C): Most plans include some dental coverage, ranging from preventive-only to comprehensive. Cost sharing, provider networks, and annual benefit caps vary by plan.
- Dual Special Needs Plans: Available if you have both Medicare and Medicaid. These coordinate dental benefits from both programs and often provide the most coverage with the least cost sharing.
The enrollment period for Medicare Advantage runs from October 15 through December 7 each year, with coverage starting January 1. If you’re comparing plans, the Medicare Plan Finder tool at medicare.gov lets you filter by dental benefits and see exactly what each plan in your area covers.
