Medicaid pays 8 cents of the dental dollar — and dentists have noticed

Dental care in the United States runs on a private market with a public sliver attached.▸ Most of the $189.2 billion Americans spent on dental services in 2024 came from private insurance and out-of-pocket payments, per the Centers for Medicare & Medicaid Services' National Health Expenditure Accounts. Medicaid — the program that's supposed to guarantee dental coverage for tens of millions of low-income children and, in many states, adults — covered just $15.2 billion of it: 8 cents of every dollar spent on teeth. That's not because Medicaid enrollees need less dental care. It's because the program pays so little for it that most dentists don't take the insurance at all.

Private insurance ($78.2 billion) and money patients pay directly ($72.5 billion) together cover four out of every five dental dollars.▸ Medicaid's $15.2 billion trails even Medicare's $12.6 billion — striking, since Medicare doesn't guarantee a dental benefit at all; most of that figure is Medicare Advantage plans bolting dental riders onto their coverage. Medicaid, by contrast, is required to cover dental care for children in every state under its Early and Periodic Screening, Diagnostic, and Treatment mandate, and more than half of states now offer at least some adult dental benefit too. The obligation is broad. The money behind it isn't.

The reason isn't a mystery — it's the fee schedule.▸ State Medicaid programs pay dentists so little that, per the ADA Health Policy Institute, fee-for-service Medicaid reimbursement in most states falls below 50% of what dentists normally charge and below 60% of what private insurers pay for the same procedure. Faced with that math, only 41% of U.S. dentists participate in Medicaid or CHIP as of 2024 — the same share as in 2015, a decade of expanded state dental benefits that did nothing to move dentist participation.

Low reimbursement doesn't just shrink Medicaid's share of the dollar — it shrinks the number of dentists willing to see Medicaid patients in the communities that most need them, which is exactly the population HRSA tracks as a Dental Care Health Professional Shortage Area (HPSA).▸ As of June 30, 2026, HRSA's Bureau of Health Workforce counted 7,951 designated dental shortage areas covering 76,757,184 people, with only 33.6% of dental need met nationally. Closing that gap entirely would take 12,760 more dentists than the country currently has in the right places.

The breakdown matters.▸ Population Group shortage areas — where a county has dentists overall, but not enough who will treat a specific low-income or otherwise underserved population at an affordable rate — account for 10,881 of the 12,760 dentists needed, or 85% of the total gap, across 59.8 million people. That's the category that overlaps most directly with Medicaid enrollees — the dentists exist, they've simply priced Medicaid patients out of their practice. Whole-county Geographic Area shortages (1,317 dentists needed) and single-site Facility shortages inside prisons, clinics, and other institutions (562 dentists needed) make up the rest.

Dental spending figures are calendar year 2024, the most recent year in CMS's historical NHE tables; HPSA figures are a live snapshot as of June 30, 2026 and will shift as HRSA re-designates areas quarterly.
