Rural U.S. faces the heaviest burden accessing dental care.

Harvard School of Dental Medicine research finds 24.7 million Americans live in dental care shortage areas and that rural residents travel, on average, about 3.2 times longer than urban residents to reach dental specialists; more than 98 percent of dental specialists practice in urban areas.

New research from the Harvard School of Dental Medicine reports wide geographic gaps in access to dental care, with rural communities particularly affected. The studies combine national analyses of general and specialty dental workforce distribution, travel times to care, and the role of public transit. Researchers note that specialty services are concentrated in urban areas and that travel distances and workforce shortages shape access. The findings are presented in peer-reviewed journals and discussed by dental researchers and policy analysts. Key findings: - An estimated 24.7 million people live in dental care shortage areas, and 49.3 million U.S. adults lack public transit access to a dental clinic. - Rural residents face much longer travel times for specialty dental care, with average drive times about 3.2 times longer than for urban residents; in states such as Alaska, Montana, Nevada, North Dakota, South Dakota, and Wyoming, drive times to specialists often exceed an hour. - More than 98 percent of dental specialists practice in urban areas; prosthodontics was the least accessible specialty, with about 85.5 million Americans living more than 30 minutes from a prosthodontist and over 10 percent facing travel times exceeding an hour. - Workforce patterns show fewer dentists per capita in rural areas (about one per 3,850 people versus one per 1,470 in urban areas), that early-career dentists are likelier to practice in underserved settings but retention falls over time, and that educational debt levels are associated with where dentists choose to practice. Summary: The research describes persistent geographic divides that limit access to both routine and advanced dental services in many rural communities, and it documents how provider location choices and financial factors shape those divides. Researchers and analysts say strategies to strengthen specialist pipelines, rural training, and workforce stability are needed; Undetermined at this time.
