Original Medicare (Parts A and B) does not cover routine dental care like cleanings, fillings, extractions, or dentures. 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 lacks. You can also buy a separate standalone dental insurance plan on your own.
Why Original Medicare Doesn’t Cover Dental
When Medicare was created in 1965, dental care was explicitly excluded from the benefit package, and that exclusion has never been changed by Congress. Parts A and B cover hospital stays, doctor visits, lab work, and a wide range of medical services, but routine dental care falls outside their scope entirely. That means no coverage for exams, cleanings, X-rays, fillings, crowns, root canals, bridges, dentures, or extractions under traditional Medicare.
There are narrow exceptions. Medicare Part A (hospital insurance) can cover dental services when they’re performed as part of an inpatient hospital stay for another covered procedure. For example, if you need a tooth extraction before heart valve surgery, or if a jaw fracture requires reconstruction, Medicare may pay for the dental work because it’s considered medically necessary to the larger procedure. Outside of these limited scenarios, Original Medicare pays nothing toward dental care.
Medicare Advantage: The Most Common Path to Dental
Medicare Advantage plans are sold by private insurance companies as an alternative to Original Medicare. They must cover everything Parts A and B cover, but most also bundle in extra benefits like dental, vision, and hearing. The majority of Medicare Advantage plans include some level of dental coverage, which is the primary reason many people choose them.
Dental benefits in Medicare Advantage plans typically fall into two tiers. Preventive coverage, which usually includes cleanings, exams, and X-rays, is often available at no extra cost or with very low copays. Comprehensive coverage, which includes fillings, crowns, root canals, dentures, and extractions, varies significantly from plan to plan.
The quality of that comprehensive coverage differs more than many people realize. Research published in Health Affairs found that truly comprehensive dental benefits, defined as plans with an annual maximum of at least $1,500 and coinsurance of 30 percent or less for major services, are available in fewer than half of U.S. counties. When the bar was raised to a $2,000 annual maximum and 25 percent coinsurance, only about 6 percent of plans qualified. Many plans that advertise “dental included” actually cap benefits at $1,000 or impose high cost-sharing on anything beyond preventive care.
Before enrolling in a Medicare Advantage plan for its dental benefit, check three things: the annual dollar cap on dental services, the coinsurance percentage for major procedures like crowns and dentures, and whether your preferred dentist is in the plan’s network. A plan with a $1,000 annual cap won’t go far if you need a crown ($1,000 or more) or dentures ($1,500 to $3,000).
Standalone Dental Insurance Plans
If you prefer to stay on Original Medicare and don’t want to switch to a Medicare Advantage plan, you can purchase a standalone dental insurance policy directly from a private insurer. These are not connected to Medicare in any way. You pay a separate monthly premium, and the plan operates on its own network and benefit structure.
Standalone dental plans for seniors generally come in two forms. Dental PPO or DHMO plans work like traditional insurance with premiums, deductibles, and annual maximums, typically ranging from $1,000 to $2,000 per year. Dental discount plans are not insurance at all but give you access to reduced rates at participating dentists in exchange for an annual membership fee. Both are widely available, though premiums tend to be higher and annual caps tend to be lower than what working-age adults get through employer plans.
One important note: Medigap plans (Medicare Supplement Insurance) do not cover dental care. Medigap policies are designed to fill gaps in Original Medicare’s cost-sharing, like deductibles and coinsurance for medical services, but dental, vision, and hearing are excluded from all standardized Medigap plan letters.
Dental Coverage for Dual Eligibles
If you qualify for both Medicare and Medicaid, you may have access to dental benefits through Medicaid that go well beyond what Medicare offers. Medicaid dental coverage varies by state, but many states cover a range of services for adults including exams, cleanings, fillings, extractions, and dentures.
Some states have taken this a step further. In New York, for example, Dual Eligible Special Needs Plans (D-SNPs), which are Medicare Advantage plans designed for people enrolled in both programs, are required to cover the full Medicaid dental benefit using Medicare funds. These plans cannot impose a capped dollar allowance on dental services, meaning enrollees get access to the complete range of covered dental care without hitting an annual maximum. Starting in 2025, New York D-SNPs must also cover any newly added Medicaid dental services. If you’re enrolled in both Medicare and Medicaid, check whether your state offers a D-SNP with enhanced dental benefits, as the coverage can be substantially more generous than a standard Medicare Advantage plan.
How to Compare Your Options
Your best path to dental coverage depends on your situation. If you’re already on Medicare Advantage or open to switching, look for a plan with a dental annual maximum of at least $1,500 and coinsurance at or below 30 percent for major services. Plans that meet this threshold offer meaningfully better protection than those with $500 or $1,000 caps, which can leave you paying most of the bill for crowns, bridges, or dentures out of pocket.
If you want to stay on Original Medicare, a standalone dental plan is your only real option since Medigap won’t help. Compare premiums against the annual maximum and consider how much dental work you expect to need. For someone who only needs two cleanings and an annual exam, a discount plan or a basic policy may be enough. For someone facing major work, a higher-premium plan with a larger annual cap will pay for itself quickly.
If you qualify for Medicaid alongside Medicare, contact your state Medicaid office or look into D-SNP plans in your area. You may already have dental coverage you’re not using, or you may be eligible for a plan that covers far more than a typical Medicare Advantage option.
