More than 45 million Americans live in dental health professional shortage areas (HPSA), where there are not enough dentists to adequately serve the population. An aging and shrinking dental workforce and a low number of graduating dental students wishing to practice in rural or urban underserved areas contribute to dental HPSAs. Without access to routine, preventive dental care, simple dental issues can lead to more severe conditions and expensive treatments.
Some states are establishing policies to reduce barriers to dental services and improve access to care for underserved populations. For example:
The District of Columbia and 33 states have publicly or privately funded dental loan repayment programs to attract graduating dental students to underserved areas.
Thirty-six states allow dental hygienists to perform some services without the specific authorization of a dentist, such as applying fluoride and sealants, enabling them to practice in settings such as schools and nursing homes. Sixteen states also allow Medicaid reimbursement directly to dental hygienists for certain services.
2009 Minnesota Senate File 2083 created new types of mid-level dental providers—known as Dental Therapists and Advanced Dental Therapists—to administer services, such as fluoride varnishes and local anesthesia, under a supervising dentist. In 2003, Alaska created mid-level Dental Health Aide Therapists to deliver services, including teeth cleanings and sealants, to Alaskan native people in rural areas with poor access to dental care.
2011 New Mexico House Bill 187 allows Community Dental Health Coordinators—under the general supervision of a dentist—to provide dental health education and basic preventive services, such as giving medications and collecting diagnostic data, in nontraditional settings.
In parts of California, Virtual Dental Homes electronically link dentists with dental hygienists and assistants who perform preventive services and screenings in schools, nursing homes and community centers. Dentists view records remotely, develop treatment plans and refer patients to dental offices for further care.

Percentage of State Population Living in a Dental Health Professional Shortage Area (HPSA)
According to the Health Resources and Services Administration, a dental HPSA either has a population to dentist ratio of at least 5,000:1 or a ratio of at least 4,000:1 with unusually high needs for dental services, or an insufficient capacity of existing dental providers.
