Despite projections of steady growth in the number of working dentists, the Health Resources and Services Administration has identified many areas and populations in the United States that have an inadequate supply of dentists to meet current or future needs. In addition to diagnosing, treating or managing oral health conditions and performing surgical procedures, dentists provide critical preventive care through routine visits. Poor oral health can negatively impact quality of life, causing pain or tooth loss, and contributing to other health conditions like eating disorders, diabetes and immune disorders. More than 40% of adults reported feeling mouth pain in the past year, and 80% of people have had at least one cavity by age 34.
Some of the most significant oral health disparities are in rural communities, which report lower access to and use of dental services and have higher rates of dental problems. Contributing factors to these disparities include:
Strategies to increase the size of the dental workforce, particularly in rural communities, include:

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
