Most Medicare Advantage plans include some dental coverage, which is a significant step up from Original Medicare, where routine dental care is almost entirely excluded. About 77% of Medicare Advantage enrollees report having dental benefits through their plan. But what’s actually covered, and how much you’ll pay out of pocket, varies widely depending on your specific plan and the type of service you need.
What Original Medicare Covers (and Doesn’t)
Original Medicare (Parts A and B) does not cover routine dental care. No cleanings, no fillings, no extractions, no dentures, no implants. You pay 100% of costs for these services out of pocket.
The only exceptions are dental services directly tied to a covered medical treatment. These include oral exams and dental work before a heart valve replacement, organ transplant, or bone marrow transplant. They also include tooth extractions to clear a mouth infection before chemotherapy, treatment for complications during head and neck cancer care, and dental exams before or during dialysis for people with end-stage renal disease. In those cases, Part B covers the dental service at the standard 80/20 split after your deductible.
This gap is exactly why dental benefits became one of the most popular supplemental features in Medicare Advantage plans.
Preventive Dental Services
Most Medicare Advantage plans that include dental coverage start with preventive care: oral exams, routine cleanings, and X-rays. These are typically covered once or twice per year. Nearly two-thirds of enrollees with access to preventive dental benefits pay zero cost-sharing for these services, meaning no copay and no coinsurance at the time of the visit.
There’s an important catch, though. Even when preventive services are “free” at the point of care, they usually count toward an annual dollar cap on your dental benefits. That cap limits the total amount the plan will pay for all dental services in a given year. If you only use preventive care, you’re unlikely to hit it. But if you need more extensive work, the cap matters a great deal.
Basic and Major Dental Services
Beyond preventive care, Medicare Advantage dental coverage is often split into tiers. Basic services typically include fillings, simple extractions, and sometimes periodontal (gum) treatments. Major services cover more complex and expensive procedures: root canals, crowns, bridges, dentures, and in some plans, implants.
Not every Medicare Advantage plan covers major services. Some plans offer preventive-only dental benefits. Others include a broader range but charge significantly higher cost-sharing for the more expensive procedures. When comparing plans, the distinction between “preventive dental” and “comprehensive dental” in the plan documents tells you which tier of coverage you’re getting.
What You’ll Pay Out of Pocket
Cost-sharing for dental services beyond preventive care is substantial. The most common coinsurance rate for extensive services, including fillings, extractions, root canals, periodontics, and dentures, is 50%. That means if a root canal costs $1,000, you’d typically owe $500. Coinsurance rates across plans range from 20% to 70% depending on the service and the plan, but 50% is the number you’ll see most often.
Plans generally use coinsurance (a percentage of the total cost) rather than flat copayments for these services. And all of this is subject to the plan’s annual dollar limit on dental benefits. Once you’ve hit that cap, you’re responsible for 100% of any remaining dental costs for the year. The size of these caps varies by plan, so checking the specific dollar limit is one of the most important steps when evaluating a plan’s dental benefits. A plan that covers crowns at 50% coinsurance sounds generous, but if the annual maximum is low, it may only cover a fraction of one crown before the cap is exhausted.
Dental Implants and Other Specialized Work
Dental implants are one of the most asked-about services, and coverage is inconsistent. Original Medicare explicitly does not cover implants. Some Medicare Advantage plans with comprehensive dental benefits do include implant coverage, but many don’t, and those that do often apply high coinsurance rates, waiting periods before you’re eligible, and the same annual caps that limit other major services.
Given that a single dental implant can cost several thousand dollars, even a plan that technically covers implants may leave you paying the majority of the bill. If implants are a priority for you, look closely at the plan’s Evidence of Coverage document for waiting periods, coinsurance percentages, and whether the annual dollar cap would meaningfully offset the cost.
How Your Plan’s Network Affects Coverage
Medicare Advantage plans use provider networks, and the type of plan you choose determines how much flexibility you have in picking a dentist.
- HMO plans generally require you to see in-network dentists. If you go out of network for non-emergency dental care, you’ll typically pay 100% of the cost yourself.
- PPO plans let you see both in-network and out-of-network dentists, but you’ll pay less with in-network providers. Out-of-network visits are covered, just at a higher cost-sharing rate.
Before enrolling, it’s worth checking whether your current dentist is in the plan’s network. Switching dentists may be a minor inconvenience, but if you’re in the middle of ongoing treatment, an out-of-network gap could mean paying full price for visits you expected to be covered.
Affordability Gaps to Be Aware Of
Having dental coverage through a Medicare Advantage plan is better than having none, but it doesn’t eliminate financial barriers. About one in four Medicare beneficiaries with dental coverage still report difficulty affording dental services. Annual dollar caps, 50% coinsurance on major procedures, and the exclusion of certain treatments all contribute to this gap.
Interestingly, Medicare Advantage enrollees with dental coverage are slightly less likely to actually use dental care (77%) compared to those in Original Medicare who obtained separate dental insurance (83%). The reasons aren’t entirely clear, but network restrictions, confusion about what’s covered, and annual limits likely play a role.
When comparing plans during open enrollment, the three numbers that matter most for dental are the annual benefit cap, the coinsurance rate for major services, and any waiting periods before comprehensive benefits kick in. A plan with a $0 premium and “dental included” may look attractive, but the details of those dental benefits determine whether the coverage is meaningful for the care you actually need.
