Oral Health in Rural Communities
The regular preventive care of the teeth and gums is important in maintaining quality of life and overall health, playing a role in preventing diseases such as diabetes and heart disease. Yet, rural communities often lack adequate oral healthcare and subsequently miss out on the benefits of good oral health as well. Several factors have been well documented as contributing to the oral health challenges of rural America:
- Access to dental care – Many rural communities lack access to oral health providers due to geographic isolation and workforce shortages.
- Oral health literacy – A 2009 study found that health literacy is lower among rural populations. In terms of oral health, poor health literacy can result in poor oral hygiene and difficulty in navigating the oral health system. In addition, rural residents with low health literacy are more likely to consume sugar-sweetened beverages and more prone to dental caries, according to a 2016 article.
- Fluoridation of water supplies – Rural communities often find fluoridated water systems to be cost prohibitive.
- Tobacco use – Cigarette smoking is more prevalent in rural areas than in urban areas (27.7% of adults in nonmetro areas vs. 20.3% of adults in large metro areas), as well as smokeless tobacco use (13.8% of adults in nonmetro areas vs. 5.9% of adults in large metro areas), according to a 2017 report. Both can cause oral health problems.
This guide highlights the resources that will support rural healthcare providers and others in promoting access of oral health services to rural adults and children.

What oral health disparities are present in rural America?
Oral health disparities in rural areas are due to factors such as workforce shortages and dental health insurance coverage on top of the geographic and social factors that affect the health outcomes of rural people broadly. Some of the specific oral health disparities in rural America are:
- In 2017, 55.7% of adults age 18-64 living outside of a metropolitan statistical area (MSA) visited the dentist in the past year, compared to 65.2% of those living within an MSA, according to Health, United States, 2018 (Table 37).
- According to a 2017 report from the South Carolina Rural Health Research Center, rural children were less likely (73% of Large Rural, 75% of Small Rural) to receive preventive dental care than urban children (78%) in 2011-2012. Rural children are also less likely to report having excellent or very good teeth.
- A 2013 report shows rural counties have higher percentages of people with partial edentulism, having several teeth pulled, when compared to urban (Urban, 38.4%, High Poverty Rural 51.3%, Other Rural, 45%) and counties with high rates of full edentulism, having all teeth pulled, are also rural (Urban, 4.3%, High-Poverty Rural 10.5%, Other Rural, 8.2%).
Seniors in rural areas are less likely than their suburban or urban counterparts to have visited the dentist in the past year and more likely to have all their teeth removed due to decay or gum disease, according to a 2018 report.
What barriers do rural communities and populations face regarding oral healthcare?
The National Advisory Committee on Rural Health and Human Services identified several factors that contribute to the problems of accessing dental care in rural America in a 2004 report:
- Geographic isolation – There are fewer dental health professionals in rural areas resulting in people having to travel farther to obtain oral healthcare.
- Lack of adequate transportation – Public transportation systems are often nonexistent, causing rural residents, particularly low-income residents, difficulty in traveling to a dentist.
- Rate of poverty is higher in nonmetro areas – Rural populations living in poverty often cannot afford dental healthcare or purchase dental health insurance.
- Large older adult population – Rural America has a higher percentage of people age 65 and over, who are less likely to have dental coverage, as they generally are not employed, and Medicare does not provide dental benefits.
- Difficulty finding providers willing to treat Medicaid patients – Low reimbursement rates cause many dentists to not accept Medicaid or Children's Health Insurance Program (CHIP) patients. According to 2017 data from the American Dental Association, approximately two-thirds of all dentists in the U.S. did not serve any publicly insured patients.
- Acute provider shortages – Approximately 60% of the nation's Dental Health Professional Shortage Areas are in rural America, according to a 2019 report.
- Lack of dental insurance – A 2010 study found that employers in rural areas are less likely to offer dental insurance than those in more populated areas.
The data.HRSA.gov interactive map of Dental Health Professional Shortage Areas (HPSA) identifies the total number and geographic location of dental HPSAs by state and county.

What are some innovative solutions to address oral health in rural communities?
The lack of access to oral healthcare due to cost, insurance coverage, and other social determinants of health in rural communities has spurred the creation of several innovative models to address this barrier. Oral healthcare integration into primary care and mobile oral healthcare delivery are two prominent models that have been deployed effectively in rural areas.
Oral Health Integration
Oral health integration refers to the integration of basic or preventive oral healthcare into primary care settings in order to expand access to dental care for underserved populations. In the U.S. Department of Health and Human Services' (HHS) Oral Health Strategic Framework: 2014-2017, the integration of oral health and primary care was identified as the number one goal in combating oral health disparities. Integration of services often includes co-location of services. The model allows for improved communication and coordination between dental and primary care providers.
An example of oral health integration is the Medical Oral Expanded Care (MORE Care) Initiative, which connects Rural Health Clinics (RHCs) with oral health professionals in their communities and develops referral networks between primary care and oral healthcare providers.

- The Harvard School of Dental Medicine Initiative Integrating Oral Health and Medicine – Highlights educational, clinical, outcomes, and policy-based research and resources for oral healthcare integration.
Mobile Oral Health Programs
Many successful mobile oral health programs have been developed and widely used in rural America. Mobile dental vans and other portable dental clinics have traveled to various rural population centers to provide preventive care, x-rays, and other dental procedures. RHIhub's Rural Oral Health Toolkit identifies resources and best practices to help implement a rural Mobile Dental Services Model.
Across the nation there are examples of mobile oral health programs providing services to rural communities:
- Delta Dental Mobile Program expands access to oral healthcare services to children in rural and urban areas of South Dakota.
- Miles for Smiles Mobile Dental Unit expands access to dental care for children in an 11 county region of southwest Missouri.
- Remote Area Medical® is an organization that offers free mobile health clinics to rural and underserved areas providing primary, dental, and vision care.
Rural providers have used existing healthcare technologies, practices, and methods to bring preventive oral care to their communities, such as the use of school-based health centers, telemedicine, and community health workers. Models for each are listed here, respectively:
- School-Based Health Center Dental Outreach – A consortium of 5 School-Based Health Centers worked together to improve the oral health of children in 6 rural parishes (counties) in Louisiana.
- Capitol Dental Care's Virtual Dental Homes – A program using teledentistry to bring preventive dental care to rural Polk County, Oregon.
- Regional Oral Health Pathway and Disabled Adults Oral Health Initiative – Both programs used Community Health Workers (CHWs) to provide outreach to rural people in need of acute and preventive dental care. Read more about CHWs in oral healthcare in the Rural Monitor article Community Health Workers Get Trained to Reduce Oral Health Disparities.
See Models and Innovations: Oral health for additional model programs providing oral health services in rural locations.
Do rural areas have sufficient dental health workforce?
Rural communities often suffer from a lack of oral health providers. According to a Health Resources and Services Administration (HRSA) quarterly report, as of December 31, 2019, 4,733 of the nation's 6,820 Dental Health Professional Shortage Areas (HPSAs) were located in rural or partially rural areas.
A 2015 report from the WWAMI Rural Health Research Center breaks down the supply of dentists practicing in rural and urban areas in 2008. There were 24.3 total practicing dentists for every 100,000 people in rural areas, whereas urban areas had 36.7 dentists per 100,000 people.
The shortage of dental professionals is frequently cited as a cause of the oral health disparities that exist in rural communities. Contributing factors to the shortage include:
- Limited slots in dental schools
- An unwillingness of providers to work in rural areas
- A large number of dentists retiring
- The growing trend of specialization in dental care
The Rural Monitor article Washington Program Trains Dental Super-Generalists to Serve Rural Communities describes a dental education program that is addressing these factors by accepting students interested in rural practice and providing specialized training to prepare them for rural practice.
Loan Repayment for Oral Health Careers
General practice dentists and registered clinical dental hygienists may qualify for the National Health Service Corps Loan Repayment Program. This is a federal program that is open to licensed dental health providers who are employed or have accepted employment at a National Health Service Corps approved site. The Indian Health Service also has a loan repayment program for those who qualify.
For more information about loan repayment programs, see RHIhub's topic guide on Scholarships, Loans, and Loan Repayment for Rural Health Professions.
What are dental therapists and how do they provide access to care for rural populations?
Dental therapy is the addition of midlevel providers to the dental healthcare system. Like physician assistants in medicine, dental therapists are able to provide preventive and restorative care.
In 2009, Minnesota authorized dental therapists to practice in all of the states' underserved areas. Minnesota has three types of dental therapist programs: Oral Health Care Practitioner (OHCP) Master's degree program; Bachelor's and Master's level Dental Therapy degree; and Master's degree in Advanced Dental Therapy.
Maine (2014), Arizona (2018), Michigan (2018) and Vermont (2016) passed legislation authorizing dental therapists to practice in their states, according to an updated 2016 report. Dental therapists have been able to practice on tribal lands in Alaska since 2004, in one tribal nation in Washington since 2016, and two tribes have been authorized under a state pilot project in Oregon since 2016. For further information on the above programs, see:

Alaska has been a leader in using dental therapists — called Dental Health Aide Therapists (DHATs) in that state — to meet the needs of Alaska Natives in very remote villages. DHATs are trained in Alaska in a two-year, post-high school competency-based primary care curriculum that incorporates preventive and clinical strategies. DHATs have been providing preventive and basic dental care to Alaska Natives since 2005. Program evaluations have shown that DHATs are technically competent and successfully treating patients under the general supervision of dentists. A 2018 study found that DHATs were linked to improved dental outcomes such as fewer extractions among children and adults in Alaska Native communities in Alaska's Yukon-Kuskokwim Delta. Additional information about Alaska's program is available from the Alaska Native Tribal Health Consortium.
The Swinomish Indian Tribal Community, a federally recognized Indian tribe in Washington State, has expanded their dental team to include a Dental Health Aide Therapist. Outside of Alaska, this is the first tribal community to train a student to become a Dental Health Aide Therapist.
In 2016, the Oregon Tribes Dental Health Aide Therapist Pilot Project was developed with the purpose of creating a new category of dental care providers and to provide dental therapy training to tribal members.
Where can I find information about fluoridation of rural community water supplies?
Community water fluoridation is consistently found to be one of the most effective means of preventing tooth decay. According to a 2016 Journal of Public Health Dentistry article every $1 spent on fluoridation saves $38 in treatment costs in a community with a population of 20,000+. However, it is proportionally much more expensive to fluoridate small community water supplies than large ones. For communities with fewer than 5,000 people, the ratio is $6 saved to every $1 spent. In addition, most of the 12.6 percent of U.S. residents using private wells are located in rural areas. These wells are typically unfluoridated.
The Centers for Disease Control and Prevention (CDC) Community Water Fluoridation website has information about water fluoridation, including maps, safety guidelines, and state statistics. The CDC's My Water's Fluoride website provides information on the fluoridation status of local community water supplies. Also, Water Fluoridation and Dental Health Indicators in Rural and Urban Areas of the United States reports on the availability of fluoridated water in both rural and urban settings and compares fluoride availability to the dental health of adults and children.
Who can I contact for information about oral health programs in my area?
The Association of State and Territorial Dental Directors (ASTDD) maintains a directory of state oral health programs with contact information and a description of their programs.
