Medicare and dental care in Tennessee: what's covered, what isn't, and how to choose
Turning 65 is when many Tennesseans lose employer dental coverage and discover that Medicare was never built to pay for teeth. Here's exactly what Medicare covers, the narrow medical exceptions, how to read a Medicare Advantage dental benefit before you enroll, and where Tennessee seniors find affordable care — especially dentures.
Original Medicare (Parts A and B) doesn't cover routine dental care — no cleanings, fillings, extractions, or dentures — except when dental work is tied to certain covered medical treatment, such as clearing infection before an organ transplant, heart valve surgery, cancer treatment, or dialysis. Medigap adds nothing for dental. Most Medicare Advantage plans include some dental, but they often have annual caps (about $1,300 on average in KFF's 2021 analysis of plans with more extensive coverage) and 50% coinsurance for major work. Annual enrollment runs October 15 – December 7.
How this page works: Medicare's dental rules come from federal law and CMS rulemaking, quoted and linked below. Plan-level figures (caps, coinsurance) come from KFF's national analyses — the most detailed published look at Medicare Advantage dental — and are national, not Tennessee-specific; the most recent detailed dollar-cap analysis is from 2021, which we label. Plans change every January, so the plan's own Evidence of Coverage is the only document that counts for your choice.
Original Medicare: the dental exclusion
This isn't an oversight or a policy that varies by state — it's written into federal law. Section 1862(a)(12) of the Social Security Act bars Medicare from paying for services “in connection with the care, treatment, filling, removal, or replacement of teeth or structures directly supporting teeth,” with narrow exceptions. Medicare.gov puts it plainly: Medicare doesn't cover most dental care, procedures, or supplies, like cleanings, fillings, tooth extractions, dentures, dental plates, or other dental devices.
| Coverage | Routine dental (cleanings, fillings, extractions, dentures) | Notes |
|---|---|---|
| Part A (hospital) | No | May pay for a hospital stay if a medical condition requires emergency or complicated dental work to be done in the hospital — but not the dental care itself, outside the exceptions below. |
| Part B (medical) | No | Pays only for dental services inextricably linked to certain covered medical treatment (next section). |
| Part D (drugs) | No | Covers prescriptions a dentist writes, such as antibiotics or pain medicine, under your plan's formulary. |
| Medigap (supplement) | No | Medigap fills Original Medicare's cost-sharing gaps; it adds no dental benefit. |
| Medicare Advantage (Part C) | Often, partly | Plans may add dental as an extra benefit. Scope, caps, and networks vary by plan — see below. |
The medical exceptions — and how they work
Since 2023, CMS rules have let Medicare pay for dental services that are “inextricably linked to, and substantially related and integral to the clinical success of” other covered medical services (42 C.F.R. 411.15(i)(3)). In practice, that means finding and treating dental infection that would endanger a covered treatment. CMS has recognized these situations:
| Covered medical treatment | Dental care Medicare may pay for |
|---|---|
| Organ transplant | Exam and treatment to find and eliminate oral infection before, or at the same time as, the transplant |
| Heart valve replacement or valvuloplasty | Exam and treatment to find and eliminate oral infection before, or at the same time as, surgery |
| Head and neck cancer treatment | Dental services needed in connection with radiation, chemotherapy, or surgery |
| Certain other cancer treatments e.g., chemotherapy, CAR-T therapy, high-dose bone-modifying drugs | Dental services needed so the cancer treatment can proceed safely |
| Dialysis for end-stage renal disease | Dental services for patients starting or receiving dialysis |
For 2026, CMS declined to add new examples (advocates had asked for conditions such as diabetes and autoimmune disorders). Two practical points: the dental work must be coordinated with your medical team — ask the transplant, cardiac, cancer, or dialysis team for the referral — and the dentist must be able to bill Medicare. Routine care after the medical treatment is over generally goes back to being excluded.
Medicare Advantage dental: common, but thinner than it looks
Medicare Advantage plans can use part of their federal payment to add “supplemental benefits,” and dental is among the most common. KFF's 2026 analysis found 98% of people in individual Medicare Advantage plans are in a plan that offers some dental benefit. But “offers dental” covers everything from two cleanings a year to substantial coverage for crowns and dentures.
| Feature | Figure | What it means for you |
|---|---|---|
| Enrollees in plans with any dental benefit Individual plans, 2026 | 98% | Nearly every plan advertises dental. The question is how much. |
| Average annual dollar cap Plans with more extensive coverage, 2021 | ≈ $1,300 | Less than the cost of one crown in many Tennessee offices. 59% of enrollees with a cap had one of $1,000 or less. |
| Most common coinsurance for major work 2021 | 50% | You pay half of the plan's allowed fee for crowns, dentures, and similar work — until the cap, then all of it. |
| Enrollees with no cost-sharing for preventive care 2021 | 64% | Cleanings and exams are usually the best-covered part — but still count toward the cap. |
| Separate dental premium 2021 | ≈ 10% of enrollees avg. $270/yr | Some plans sell richer dental as an optional add-on rider. |
| Prior authorization 2026 | Most enrollees | KFF found most enrollees in plans with preventive dental face prior authorization requirements. Expect approval steps for bigger work. |
Why the 2021 numbers? KFF's 2026 brief reports how many plans offer dental but not the dollar caps; its 2021 analysis is the most recent detailed national look at caps and coinsurance. Caps may have changed since — which is exactly why you should read your own plan's numbers using the checklist below.
Before you enroll: the eight-question dental checklist
The plan summary will say “dental included.” The Evidence of Coverage document (every plan publishes one) is where the real answers live. Look up each of these for every plan you're comparing.
- What's the annual dental maximum? One number for everything, or separate limits for preventive and comprehensive care?
- Is it preventive-only, or comprehensive? Preventive means exams, cleanings, X-rays. Comprehensive should list fillings, extractions, root canals, crowns, and dentures explicitly.
- What do I pay for major work? Find the coinsurance or copay for crowns and dentures specifically.
- Are dentures covered — and how often? Many plans limit replacement to once every several years.
- Is my dentist in the network? Call the dental office, not just the plan, and name the exact plan. Out-of-network dental is often not covered at all on HMO-style plans.
- Is there a waiting period before major services are covered?
- Does dental cost extra? Look for an optional dental rider and its monthly premium.
- What needs prior authorization? Know before treatment day, not after.

Your realistic options at 65
No option is right for everyone; the right one depends on your mouth, your doctors, and your budget. We don't recommend a plan — here are the tradeoffs.
| Route | Works well when… | Watch out for… |
|---|---|---|
| Medicare Advantage with dental | You mostly need cleanings, exams, and occasional fillings, and your dentist is in-network | Low annual caps, 50% coinsurance, networks, and prior authorization. Choose the plan for your medical needs first; dental is a small part of its value. |
| Original Medicare + standalone dental insurance | You want to keep Original Medicare's freedom to see any doctor | Annual maximums, waiting periods for major work (often 12 months or more), and missing-tooth clauses. See our insurance guide. |
| Dental discount plan or in-house membership | You need predictable preventive care and want a known discount | It isn't insurance — you pay the discounted fee in full. |
| Pay cash, from savings or an HSA | You have a known, one-time need (such as a set of dentures) and can compare quotes | You can't contribute new money to an HSA once you're enrolled in Medicare, but you can spend what's already there on dental. |
Timing that saves money
- Annual Enrollment Period: October 15 – December 7. Changes take effect January 1. If dental matters to you, compare plans now.
- Medicare Advantage Open Enrollment: January 1 – March 31. If you're in an Advantage plan, you can switch to another Advantage plan or return to Original Medicare once during this window.
- Before you lose employer coverage, get a full exam and finish any planned work while your current dental plan still pays.
- Large treatment plans can often be split across two calendar years so two annual maximums apply. Ask the dentist whether that's clinically safe for your case.
If you have Medicare and TennCare
Some Tennesseans qualify for both programs (“dual-eligible”). This matters for dental, because TennCare covers dental care for its adult members and Medicare doesn't.
01 Full TennCare coverage
TennCare's adult dental benefit, in place since January 1, 2023, applies to “all adults enrolled in TennCare.” If you have full TennCare benefits alongside Medicare, call Renaissance at 866-864-2526 to confirm your dental coverage and find an in-network dentist before paying out of pocket. Covered services include cleanings, fillings, crowns, root canals, extractions, and partial and complete dentures, when medically necessary.
02 Help with premiums only
Some people get help paying Medicare premiums and cost-sharing through a Medicare Savings Program without having full TennCare benefits. That help is valuable, but it isn't the same as TennCare dental coverage. If you're unsure which you have, ask TennCare Connect (855-259-0701) or TN SHIP (877-801-0044).
03 Dual Special Needs Plans
Several insurers sell Medicare Advantage “D-SNPs” in Tennessee for people with both Medicare and TennCare, often with their own dental benefits. Ask how the plan's dental benefit works alongside TennCare's — which pays first, and whether you'd have to use a different dentist for each.

Why this matters, and where seniors find lower-cost care
The gap is large. In KFF's analysis, 47% of Medicare beneficiaries — about 24 million people — had no dental coverage (2019), and 47% hadn't seen a dentist in the past year (2018). Among those who did use dental care, average out-of-pocket spending was $874, and one in five spent more than $1,000. Gum disease peaks in this age group: the National Institute of Dental and Craniofacial Research reports periodontitis in 59.8% of adults 65 and older (NHANES 2009–2014).
- Dental school clinics: the University of Tennessee Health Science Center College of Dentistry (Memphis) and Meharry Medical College School of Dentistry (Nashville) offer faculty-supervised care, including dentures, typically below private-practice fees, in exchange for longer and more frequent appointments.
- Dental hygiene school clinics: programs such as ETSU (Johnson City), Roane State (Oak Ridge), and Chattanooga State offer low-cost cleanings when students are in session.
- Community health centers and health department clinics: sliding fees by income. Note that Tennessee's Uninsured Adult Healthcare Safety Net covers ages 19–64 only, so it doesn't serve most Medicare beneficiaries; health department and community health center clinics have no such age limit.

Questions people actually ask us
In the words patients use — because the worry behind the question is usually the real question.
Original Medicare (Parts A and B) does not cover routine dental care such as cleanings, fillings, extractions, or dentures. Federal law, Section 1862(a)(12) of the Social Security Act, excludes it. Medicare can pay for dental services only when they are inextricably linked to certain covered medical treatment, such as clearing oral infection before an organ transplant, heart valve surgery, certain cancer treatments, or dialysis.
No. Original Medicare doesn't cover dentures, dental plates, or other dental devices, and Medigap adds no dental coverage. Some Medicare Advantage plans cover dentures, usually with 50% coinsurance, an annual dollar cap, and a limit on how often they can be replaced. If you have full TennCare coverage alongside Medicare, TennCare covers medically necessary partial and complete dentures; call Renaissance at 866-864-2526 to confirm.
Most do, in some form. KFF found 98% of people in individual Medicare Advantage plans in 2026 are in a plan that offers some dental benefit. But coverage ranges from preventive-only to more comprehensive care, and plans usually impose annual dollar caps (about $1,300 on average among plans with more extensive coverage, in KFF's 2021 analysis), 50% coinsurance for major work, networks, and prior authorization. Check the plan's Evidence of Coverage.
No. Medicare Supplement (Medigap) policies help pay Original Medicare's deductibles and coinsurance, but they add no dental benefit. People with Original Medicare and Medigap usually buy a separate dental policy, use a discount plan, or pay directly.
During the Annual Enrollment Period, October 15 through December 7, with changes taking effect January 1. If you're already in a Medicare Advantage plan, you can also switch plans or return to Original Medicare once during Medicare Advantage Open Enrollment, January 1 through March 31. Free, unbiased counseling is available from Tennessee's SHIP program at 877-801-0044.
It may. CMS allows Medicare to pay for dental exams and treatment needed to find and eliminate oral infection before or alongside an organ transplant or heart valve replacement, and for dental services tied to head and neck cancer treatment, certain other cancer treatments, and dialysis for end-stage renal disease. The dental care must be coordinated with your medical team, so ask them for the referral before scheduling.
If you have full TennCare benefits, the adult dental benefit applies to all adults enrolled in TennCare and covers medically necessary services such as cleanings, fillings, crowns, root canals, extractions, and dentures. If you only get help with Medicare premiums through a Medicare Savings Program, that isn't full TennCare coverage. Call Renaissance at 866-864-2526 to confirm before paying out of pocket.
Start by checking whether you have full TennCare coverage, which covers medically necessary dentures. Otherwise, compare a Medicare Advantage plan's denture benefit against its cap, price dentures at the dental school clinics at UTHSC in Memphis or Meharry in Nashville, and ask community health centers about sliding fees. Get every quote in writing, with extractions, adjustments, and relines listed separately.
