Why Medicare Still Doesn’t Cover Routine Dental Care — and What Could Change

Medicare’s dental policy flows from Section 1862(a)(12) of the Social Security Act and implementing regulations. CMS describes dental services as excluded except in specific circumstances, including inpatient hospital services when a patient’s underlying medical condition or the severity of a dental procedure requires hospitalization. That is why the gap cannot simply be solved by a dentist submitting the right code or a Medicare contractor changing a payment rule. Routine dental coverage would require a broader policy decision. ¹

This matters because it explains why decades of growing evidence about oral and systemic health have not automatically translated into a universal Medicare dental benefit. Scientific integration and benefit integration are different processes. A program can recognize that oral health matters to medical care while still excluding routine dentistry from its core benefit package.

The most interesting policy development is that Medicare’s dental exclusion is not absolute. CMS says Part A and Part B can pay for dental services when those services are inextricably linked to the clinical success of another Medicare-covered procedure or service. This creates an important conceptual shift: dental care can be covered when it is necessary to make covered medical care work. ¹

That logic is fundamentally different from a routine dental benefit. Medicare is not paying for preventive dentistry because oral health is broadly important. It is recognizing that certain dental conditions can interfere with medical treatment and that treating those conditions can become part of the covered medical episode. The distinction is narrow, but it establishes that the mouth cannot always be separated from the rest of care.

For healthcare policy, this is one of the most consequential phrases in the current dental coverage framework. It creates a bridge between a statutory exclusion and clinical reality. Dental services do not become covered because they are good for health in general; they become potentially payable when they are sufficiently tied to the success of a specific covered medical service. ¹

This framework naturally favors oncology, transplant and other situations where oral infection or dental status can directly affect treatment planning. It is less useful for the everyday burden of caries, periodontal disease, tooth loss and preventive care that affects millions of older adults. In that sense, Medicare can acknowledge oral-medical interdependence while still leaving the majority of dental need uncovered.

CMS notes that some Medicare Advantage plans can cover routine and other dental services as supplemental benefits. That has made Medicare Advantage the primary route through which many Medicare beneficiaries receive some form of dental coverage. ¹

But supplemental dental benefits are not the same as a standardized national dental benefit. Plans can vary in covered services, networks, annual limits, cost sharing and utilization rules. The existence of dental coverage in Medicare Advantage demonstrates consumer demand and plan willingness to offer the benefit, while also preserving substantial variation across products and markets.

Medicare Advantage plans sit in an unusually interesting position for oral-systemic care. They manage medical risk, often offer dental benefits and can theoretically connect medical and dental data inside the same insurance organization. That creates a natural environment for testing whether targeted dental interventions improve medical outcomes or member experience.

A plan could, for example, identify members with diabetes who have not used dental benefits, reduce periodontal cost sharing, navigate members into care and track medical outcomes. It could connect oncology treatment pathways to dental clearance or build referral programs between dental and primary care. The challenge is not simply offering a dental allowance; it is using the benefit as part of an integrated health strategy.

The intuitive answer is cost. A universal dental benefit would add federal spending, and the size of that spending would depend heavily on benefit design. Coverage with low annual limits and high cost sharing would cost less but leave substantial need unmet. Richer coverage could improve access but would require more public financing and enough participating providers to absorb demand.

There are also political and administrative questions: Should dental be structured like Part B? Should beneficiaries pay a separate premium? What services should be covered? How should dentures, implants and major restorative care be treated? What fee schedule should Medicare use? How should network adequacy be managed? A dental benefit sounds simple until it becomes a national insurance program.

Coverage does not equal access. Medicaid offers the clearest warning: even when dental benefits exist, reimbursement levels, administrative burden and provider participation can constrain real-world access. A Medicare dental benefit would need enough dentists willing to participate, particularly in rural and underserved areas.

Older adults can also have more medically complex dental needs. Polypharmacy, anticoagulation, diabetes, cancer history, cognitive decline, mobility limitations and transportation barriers can complicate ordinary dental access. A benefit designed around reimbursement alone may not solve those delivery problems.

NIDCR’s national oral-health work emphasizes that oral health is essential to overall health and well-being and that substantial disparities persist in access and disease burden. The 2021 Oral Health in America report drew on hundreds of contributors and highlighted persistent chronic oral-health problems even after decades of scientific and clinical progress. ²³

For older adults, the stakes include pain, infection, chewing difficulty, nutrition, tooth loss, social function and the ability to complete medical treatment. Those outcomes are meaningful even without proving that dental care lowers total medical spending. Policy debates can become distorted when oral care is asked to justify itself only through downstream medical savings.

A broad Medicare dental benefit has historically been discussed as an expansion of benefits. The emerging oral-systemic framework creates another argument: dental care can be part of medical care for populations where the separation is clinically artificial. CMS’s current integral-services policy already reflects that logic in narrow circumstances. ¹

The question is whether policy moves incrementally outward from those exceptions. Could more conditions qualify when untreated oral disease predictably interferes with covered medical treatment? Could certain high-risk groups receive targeted benefits? Could traditional Medicare test integrated oral-health models through demonstrations before Congress creates a universal benefit? Those paths may be more politically achievable than a single sweeping change.

One plausible future is disease-specific dental coverage. Medicare could cover defined periodontal or preventive services for people with diabetes, immunosuppression, cancer treatment or other high-risk conditions if evidence demonstrates clinical benefit. That would mirror the logic already used for dental services integral to covered care while expanding the range of circumstances in which oral intervention is treated as medically relevant.

The strength of this approach is that it can be evidence-based and measurable. The weakness is fragmentation. A beneficiary’s access to routine oral care should not necessarily depend on having the right medical diagnosis. Targeted benefits can become a bridge toward integration while leaving the underlying dental exclusion intact.

Policy will move faster if integrated datasets can show what dental coverage changes. Medicare has enormous medical-claims data but, in traditional Medicare, limited routine dental claims because the services are generally excluded. Medicare Advantage plans and external dental insurers may therefore hold some of the most useful evidence on oral-medical utilization patterns in older adults.

Research should ask narrower questions than 'does dental save Medicare money?' Which services reduce avoidable complications before covered procedures? Which populations experience the largest access barriers? Does periodontal treatment in diabetes change utilization? Do richer dental benefits reduce emergency dental care? Which benefit designs produce actual treatment completion rather than unused allowances? Those are policy-grade questions.

Because Medicare Advantage plans can offer supplemental dental benefits and manage medical risk, they can move faster than statutory traditional Medicare. Plans can test targeted outreach, combined benefits, integrated provider arrangements and data-driven navigation. Successful models could eventually inform broader policy. ¹

The risk is that benefit variation makes outcomes difficult to compare. A generous dental benefit with a strong network is fundamentally different from a small annual allowance. Researchers and policymakers should avoid treating 'dental coverage' as a binary variable when the underlying product design differs dramatically.

A serious reform agenda would address four layers at once: coverage, access, integration and evidence. Coverage determines what is payable. Access determines whether beneficiaries can actually receive care. Integration determines whether dental and medical teams can coordinate. Evidence determines whether policymakers can identify which models improve outcomes and justify investment.

A benefit that covers cleanings but leaves medically complex patients unable to find a dentist is incomplete. A dental network that treats patients but cannot see relevant medical information is incomplete. A rich benefit with no measurement strategy may improve oral health but teach policymakers little about broader healthcare value. The future of Medicare dental policy should be evaluated as a system, not a fee schedule.

Traditional Medicare still does not cover routine dental care because dental services remain broadly excluded by statute and regulation. CMS has, however, created important pathways for dental services that are inextricably linked to the success of covered medical care, while Medicare Advantage plans can offer routine dental benefits as supplemental coverage. ¹

That combination tells us where the policy is heading even if it does not tell us how fast. The old boundary between dental and medical care is becoming harder to defend clinically, but changing a national insurance program requires more than science. The next phase will depend on evidence, cost, provider access and whether policymakers increasingly view oral care not as an optional add-on, but as one component of healthcare for an aging population.
