The Scale of the Dental Shortage

HRSA designates dental Health Professional Shortage Areas using a population-to-dentist threshold of 5,000:1 (or 4,000:1 for areas with high need indicators). By this measure, more than 60 million Americans live in a designated dental HPSA. But the official designation understates the problem — many communities that technically meet minimum ratios still face practical access barriers because available dentists do not accept Medicaid or are unaffordable for uninsured patients.

The dental shortage is scored separately from primary care and mental health shortages, using a 0 to 26 scale (one point higher than the 0-25 scale for other categories). High scores indicate severe need. Browse the dental shortage rankings to see how states compare, or check your county's dental HPSA status.

Why Dental Access Is Uniquely Difficult

The dental shortage has structural characteristics that distinguish it from other healthcare access problems:

The Insurance Gap

Dental insurance in America is fundamentally different from medical insurance. The Affordable Care Act requires dental coverage for children but not for adults. Medicaid covers dental care for children in all states, but adult dental Medicaid benefits vary enormously — some states provide comprehensive coverage, others cover only emergency extractions, and a few provide virtually no adult dental benefits at all.

This creates a massive access gap: tens of millions of low-income adults have no dental coverage. Even those with Medicaid often cannot find dentists who accept it — Medicaid dental reimbursement rates are typically 30-50% of commercial rates, making it financially unfeasible for many dental practices.

The Training Pipeline

The US has approximately 65 dental schools producing around 6,000 graduates per year. While this roughly matches the number of dentists retiring annually, it does not produce net growth in the dental workforce — and it certainly does not produce growth in shortage areas, where most new graduates do not choose to practice. Dental school is among the most expensive professional education, with average student debt exceeding $300,000, creating financial pressure to practice in higher-income communities where revenue supports debt repayment.

Geographic Concentration

Dentists are heavily concentrated in urban and suburban areas. Rural communities face the most severe dental shortages — some rural counties have no dentist within a 60-mile radius. Even within metro areas, dental practices cluster in higher-income neighborhoods, leaving low-income urban areas with de facto dental deserts despite adequate metro-wide provider counts.

Health Consequences of Untreated Dental Disease

The consequences of the dental shortage extend far beyond oral discomfort:

• Systemic health effects — Periodontal disease is associated with increased risk of cardiovascular disease, stroke, diabetes complications, respiratory infections, and adverse pregnancy outcomes including preterm birth. The oral-systemic health connection is well-documented in medical literature but poorly reflected in how the US healthcare system separates dental from medical care.
• Emergency room burden — An estimated 2 million emergency room visits per year in the US are for dental conditions. ER visits for dental problems cost an average of $750-1,500 and typically provide only pain management and antibiotics — not definitive treatment. These visits represent billions in annual healthcare spending for inadequate care.
• Childhood development — Tooth decay is the most common chronic childhood disease in America. Children with untreated dental disease miss more school days, experience difficulty eating and sleeping, and show lower academic performance. In shortage areas, children's dental disease goes untreated at significantly higher rates.
• Economic impact — Adults with untreated dental disease report more missed workdays, lower employment rates, and reduced lifetime earnings. Visible dental problems create barriers to employment in customer-facing roles. The economic cost of the dental shortage falls disproportionately on communities least able to absorb it.

Who Bears the Burden

Children in Low-Income Families

Despite Medicaid's dental coverage mandate for children, finding a Medicaid-accepting dentist remains a significant barrier. In many shortage areas, families drive hours for children's dental appointments or simply go without. School-based dental sealant programs — where dental hygienists apply preventive sealants in schools — have proven effective but reach only a fraction of eligible children.

Rural Residents

Rural dental shortages are the most geographically severe. The combination of low population density (insufficient patient volume to support a practice), distance from dental schools (reducing recruitment pipeline), and lower average incomes (reducing ability to pay) creates persistent shortage conditions that recruitment incentives have struggled to overcome.

Elderly Adults

Medicare does not cover routine dental care — a significant gap given that dental disease rates increase with age. Elderly adults on fixed incomes who lose employer-sponsored dental coverage at retirement face full out-of-pocket costs for dental care. In nursing homes and long-term care facilities, dental care access is particularly poor, leading to high rates of untreated disease, pain, and nutritional compromise.

Tribal and Indigenous Communities

American Indian and Alaska Native communities face some of the most severe dental shortages in the country. The Indian Health Service (IHS) dental program is chronically underfunded relative to need, and many tribal communities are in remote locations far from alternative dental providers. Dental disease rates in tribal communities are among the highest nationally.

Approaches to Solving the Shortage

Multiple strategies are being deployed to expand dental access, with varying levels of evidence and scale:

• NHSC dental placements — The National Health Service Corps offers loan repayment for dentists serving in HPSAs. Dental placements have grown as a share of NHSC commitments, helping staff FQHCs and safety-net clinics in shortage areas.
• FQHC dental expansion — Many Federally Qualified Health Centers have added or expanded dental clinics to serve their patient populations. FQHCs provide dental care on a sliding-scale fee basis regardless of insurance status. Use the HRSA Health Center Finder to locate dental-capable FQHCs near you.
• Dental therapists — A mid-level provider model where dental therapists perform routine procedures (fillings, simple extractions, sealants) under dentist supervision. Approximately a dozen states now authorize dental therapists in some form. Research from tribal communities and international settings shows comparable outcomes to dentist-provided care for routine procedures. Expanding this model could significantly increase effective dental capacity in shortage areas.
• Tele-dentistry — While teeth cannot be treated remotely, tele-dentistry enables remote screening, treatment planning, and referral coordination. Community health workers or dental hygienists can collect images and data in the field for remote dentist review, reducing the need for patients to travel for initial assessment.
• School-based programs — Dental sealant programs, fluoride varnish applications, and screening programs delivered in schools reach children who would otherwise not access dental care. These programs are cost-effective and produce measurable reductions in childhood dental disease.
• Medicaid reimbursement reform — States that have increased Medicaid dental reimbursement rates see measurable improvements in provider participation and patient access. The evidence strongly supports reimbursement as a lever for expanding the effective dental provider supply.

How to Find Dental Care in a Shortage Area

If you live in a dental shortage area and need care, practical options include:

• Search for FQHCs with dental services near you at findahealthcenter.hrsa.gov
• Contact your state dental association for reduced-cost care referrals
• Check for dental school clinics — supervised student care at 50-70% of private practice costs
• Look for Remote Area Medical (RAM) events in your region — these periodic free clinics include dental services
• Ask about your hospital's charity care program for dental emergencies
