Medicare Part B covers only three dental procedures, and most dental work is not included

Medicare Part B pays for dental services in very limited circumstances. The program covers dental exams, X-rays, and cleanings only when they are part of treatment for a medical condition — not for routine dental care. For example, if you need tooth extraction before heart surgery, Medicare Part B may cover the dental work. If you need a filling because of a cavity, it will not.

The three services Part B covers are: oral surgery (tooth extraction), periodontal disease treatment, and dental services required before or after a covered medical procedure. Even then, your dentist must be enrolled as a Medicare provider, and the work must be deemed medically necessary by Medicare, not just recommended by your dentist.

Most seniors find that Medicare Part B dental coverage is so narrow that it does not change their out-of-pocket dental costs. If you have regular dental needs — cleanings, fillings, crowns, dentures, root canals — you will pay for those yourself or through a separate dental plan.

Key Takeaways

  • Medicare Part B covers tooth extraction and periodontal disease treatment only when medically necessary for a covered condition, not for routine dental problems.
  • Routine dental care — cleanings, fillings, crowns, root canals, dentures, and implants — is not covered by Medicare Part B under any circumstance.
  • Your dentist must be a Medicare-enrolled provider and must document that the work is medically necessary, not just dentally recommended.
  • Most seniors purchase a separate dental plan, use a dental discount program, or pay out of pocket for routine dental work.

Which dental procedures Medicare Part B will and will not cover

Medicare Part B covers oral surgery when it is medically necessary. This typically means tooth extraction when the tooth is causing a medical problem — infection that threatens your health, damage from an accident or injury, or removal required before another covered medical procedure. A tooth extracted because of decay or gum disease may be covered if the underlying condition is severe enough to be considered a medical problem rather than a dental one. The distinction is important: Medicare asks whether the tooth itself is the medical issue, not whether you need dental care.

Medicare Part B also covers periodontal disease treatment — treatment of gum disease — when it is severe. This is rare in practice. Your dentist must document that the gum disease is causing a systemic medical condition (affecting your whole body) or is severe enough to require surgical intervention. Routine gum disease treatment, scaling, root planing, or maintenance does not may have access to.

Medicare Part B covers dental services required before or after a covered medical procedure. If you need a tooth extracted before heart surgery, or if you need dental work to prepare for radiation therapy to the head or neck, Medicare Part B may cover the dental work. The dental work must be directly tied to the medical procedure and must be documented as necessary by both your physician and your dentist.

Everything else — routine cleanings, fillings, crowns, root canals, dentures, bridges, implants, orthodontics, and cosmetic dental work — is not covered by Medicare Part B, regardless of your age or health status.

How to learn about a specific dental procedure might be covered

Before your dentist performs any work, ask whether they believe it may be covered by Medicare Part B. Your dentist should contact Medicare or check the Local Coverage information (LCD) for your region to see whether the specific procedure is listed as potentially covered. Not all dentists are familiar with Medicare Part B dental coverage rules, so you may need to ask directly or contact Medicare yourself.

You can call Medicare at 1-800-MEDICARE (1-800-633-4227) and describe the procedure your dentist has recommended. Medicare will tell you whether the work is typically covered. You can also ask your dentist to submit a request for a predetermination — a formal question to Medicare asking whether a specific procedure will be covered before the work is done. This takes time (usually two to four weeks) but protects you from unexpected bills.

If Medicare says the procedure is not covered, your dentist may still perform it, but you will pay the full cost. If your dentist is not a Medicare provider, you will pay the full cost regardless of what Medicare says. Ask your dentist whether they accept Medicare before scheduling.

Why routine dental care is not covered and what to do instead

Medicare Part B excludes routine dental care because the program was designed to cover medical services, not dental services. Dental insurance is a separate product with its own rules, costs, and coverage limits. Medicare assumes that people will purchase dental coverage separately or pay out of pocket for routine dental work.

If you do not have dental coverage, you have several options. Some seniors purchase a standalone dental plan through a private insurance company. These plans have monthly premiums (usually $10 to $30), annual deductibles (usually $50 to $150), and coverage limits (often $1,000 to $1,500 per year). They typically cover cleanings and exams at 100%, fillings and extractions at 80%, and major work like crowns at 50%. Waiting periods are common — you may have to wait six to twelve months before major work is covered.

Other seniors use a dental discount program (also called a dental savings plan). These are not insurance — they are membership programs that give you discounts at participating dentists, usually 10% to 60% off standard fees. They have no waiting periods, no annual limits, and no deductibles. They cost $80 to $200 per year. They work best if you have a dentist you trust and want to negotiate lower fees.

Some seniors straightforward pay out of pocket and shop around for the best price. A routine cleaning costs $75 to $200, a filling costs $150 to $300, and a crown costs $800 to $1,500, depending on your location and the dentist's fees. Asking for a discount or a payment plan is common practice.

Medicare Advantage plans and dental coverage

Some Medicare Advantage plans (Part C) include dental coverage as an added benefit. These plans are sold by private insurance companies and combine Part A and Part B coverage. Many offer dental benefits that Original Medicare does not — usually a small annual benefit ($0 to $1,500) that covers cleanings, exams, and sometimes basic work like fillings.

If dental coverage is important to you, check the dental benefits offered by Medicare Advantage plans in your area during the annual enrollment period (October 15 to December 7). The coverage varies widely by plan and by region. Some plans cover only cleanings and exams; others cover more extensive work. Read the plan's dental summary carefully — the benefit limit, the deductible, and which dentists are in the network all affect what you actually pay.

If you switch to a Medicare Advantage plan for dental coverage, you must stay in the plan for the full year. You can switch back to Original Medicare during the annual enrollment period, but you cannot switch plans mid-year unless you have a may have access to life event.

What happens if you need dental work and have no coverage

If you need dental work urgently and have no coverage, contact your local dental school or a federally may have access to health center (FQHC). Dental schools offer services at reduced cost — usually 30% to 50% below private practice fees — performed by dental students under supervision. The work takes longer but is thorough. Search "dental school near me" or call your state dental board for a list.

Federally may have access to health centers sometimes offer dental services on a sliding fee scale based on your income. Call 211 or search the HRSA Find a Health Center tool online to locate one near you. Some offer emergency extractions at low cost if you cannot afford other treatment.

If you have a medical condition that makes dental work urgent — infection, severe pain, or work required before surgery — tell your doctor. In some cases, a physician can refer you to a hospital-based dental clinic or help you access emergency dental care through the hospital system.

Frequently Asked Questions

Does Medicare Part B cover teeth cleaning?

No. Medicare Part B does not cover routine teeth cleaning, even if your dentist recommends it. Cleaning is covered only if it is part of treatment for a medical condition — for example, cleaning before gum surgery for severe periodontal disease. Routine preventive cleaning is not covered.

Will Medicare Part B pay for a crown or filling?

No. Crowns, fillings, root canals, and other restorative dental work are not covered by Medicare Part B. These are considered dental services, not medical services. You must pay out of pocket or use a separate dental plan.

What if my dentist says the work is medically necessary?

Your dentist's recommendation is not enough. Medicare must agree that the work is medically necessary for a covered condition. Ask your dentist to submit a predetermination request to Medicare before the work is done. Medicare will review the medical documentation and tell you whether it will cover the procedure.

Can I use Medicare Part B to pay for dentures?

No. Dentures, bridges, implants, and other prosthetic dental devices are not covered by Medicare Part B. You must pay out of pocket or use a separate dental plan. Some Medicare Advantage plans include a small denture benefit, but Original Medicare does not.

Is there any way to get dental coverage as a Medicare beneficiary?

Yes. You can purchase a standalone dental plan, join a dental discount program, switch to a Medicare Advantage plan that includes dental benefits, or use a dental school or federally may have access to health center for reduced-cost care. Each option has different costs and coverage limits — compare them based on the dental work you actually need.
