Why Medicare and Health Insurance Don't Cover Teeth

It is one of the most common complaints about health cover in the US, and in Australia and Canada too: the plan pays for almost every part of the body except the mouth. This guide explains why dental care sits outside most health insurance, what Medicare does and does not pay, when medical insurance will pay for dental treatment, how other countries handle it, and what your options are when the bill is yours.

Why is dental care not covered by health insurance?

Mostly because dentistry grew up as a separate profession with its own insurance, and the big public programmes were designed around that split. When Medicare was created in 1965, routine dental care was left out, and it has been excluded ever since (KFF, 2021). Private health plans followed the same pattern, and dental cover developed as a separate product built around check-ups and cleanings.

The Affordable Care Act kept the split for adults. HealthCare.gov states that "dental coverage isn't an essential health benefit for adults", so health plans do not have to include it. For children it is an essential health benefit and must be available, either inside a health plan or as a separate dental plan.

None of this means teeth are medically unimportant. Dental infections can become serious, and the exceptions Medicare does make, described below, exist because some dental problems put other treatment at risk. The split is administrative and historical, not clinical.

Does health insurance cover dental and vision, or do you need separate dental insurance?

For most adults in the US, you need separate dental insurance. A standard medical plan pays for doctors, hospitals and prescriptions, while routine dental care is bought as a separate plan, either through an employer or on its own. On the HealthCare.gov Marketplace you can only buy a dental plan at the same time as a health plan, and separate dental plans can have waiting periods before they cover services for adults.

Many people do have some dental cover: 74% of US adults, about 197.6 million, reported having dental insurance in 2025 (CareQuest Institute, 2026). But dental plans work differently from health insurance. They usually pay in full for cleanings, pay a share of fillings and major work, and stop at an annual maximum, which most plans set at USD 1,500 or more. Our guide to dental insurance annual maximums and implants explains what that means for a large treatment plan.

Does Medicare cover dental care?

Original Medicare does not cover routine dental care. Medicare.gov states that in most cases Medicare "doesn't cover dental services like routine cleanings, fillings, tooth extractions (removals), or items like dentures and implants". Nearly half of Medicare beneficiaries, 47% or about 24 million people, had no dental coverage in 2019 (KFF, 2021).

There are limited exceptions where dental care is tied to other Medicare-covered treatment. Medicare.gov lists, for example, an oral exam and dental treatment before a heart valve replacement or an organ or bone marrow transplant, removing teeth to treat a mouth infection before cancer treatment, treating complications of head and neck cancer therapy, and dental exams before and during dialysis for end-stage kidney disease. Some dental procedures can also be covered when you are admitted to hospital as an inpatient because of an underlying condition.

Medicare Advantage plans often add dental benefits on top. In KFF's 2021 analysis, plans with more extensive dental cover had an average annual limit of about USD 1,300, more than half of enrollees in those plans were capped at USD 1,000 or less, and the most common coinsurance for fillings and root canals was 50%. That helps with check-ups and small repairs; it rarely goes far toward dentures or implants.

When will medical insurance pay for dental treatment?

Usually only when the dental work is part of treating another medical problem, and the plan agrees in writing that it is medically necessary. Losing teeth with age or needing to chew better is not normally enough on its own. The clearer the link to a medical condition, the better the chance.

If you think your case qualifies, ask the treating dentist or surgeon to write to your medical plan with the diagnosis and why treatment is needed, and ask the plan for a decision before treatment starts. If the plan refuses, you can appeal. Our guide to appealing a health insurance denial sets out the steps.

Does Medicare cover dental in Australia, and what about the UK and Canada?

Not in general. In Australia, healthdirect states that the government "does not generally cover the costs of dental services. You will need to pay most dental costs yourself." The Child Dental Benefits Schedule covers eligible children only, and adults rely on private extras cover, which pays part of the cost with limits on what you can claim each year.

In Canada, the Canadian Dental Care Plan covers residents with an adjusted family net income under CAD 90,000 and no access to private dental insurance. Co-pays are 0% under CAD 70,000, 40% from CAD 70,000 to 79,999 and 60% from CAD 80,000 to 89,999 (canada.ca). Its list of covered services names crowns but not implants.

In the UK, NHS dental care exists but is hard to reach. In late 2024, 94.1% of adults in England without a dentist who had tried to book an NHS appointment in the previous 28 days had failed to get one (ONS, December 2024). Implants are generally not available on the NHS except in specific medical cases, such as oral cancer, trauma or cleft.

What can you do if your insurance will not cover your teeth?

Start at home: dental schools, community health centres with sliding-scale fees, a payment plan with your own dentist, and in Canada, the dental care plan if you qualify. Ask for an itemised written estimate and a cash price, because the fee for an uninsured patient is not always the same as the billed fee.

Treatment abroad is another option worth pricing, especially for larger treatment plans. In China, patients report paying a median of about CNY 6,000 (≈ USD 900) for one implant with crown, CNY 2,000 (≈ USD 300) for an all-ceramic crown, CNY 1,100 (≈ USD 160) for a root canal and CNY 400 (≈ USD 60) for a filling (Chinese patient reports, 2025–26). At a standard department of a public hospital, foreign patients pay the same listed price as local patients who pay without insurance; international departments charge more. Chinese health insurance does not cover visitors, so this is a self-pay comparison.

Travel has its own costs and limits. Implants usually need two trips about 3–6 months apart, while crowns, root canals and fillings can often be done in one stay. Bring your recent X-rays, and leave with copies of every scan and record so your dentist at home can follow up. For many people, the right plan is a mix: check-ups and small repairs at home, and the large work wherever the total cost, travel included, makes sense.
