Millions of Americans Lack Access to Dental Care

Dental problems can lead to serious health risks if they are left untreated. These problems are preventable with regular access to dental care. Yet, millions of Americans do not have access to a dentist, especially low-income families, older people, people with disabilities, tribal communities, and some communities of color.

The barriers that limit access to dental care can be social, cultural, economic and/or geographic. Some states are addressing these barriers by authorizing the use of dental therapists as part of the dental team.

What is a Dental Therapist?

Dental therapists are highly trained oral health practitioners that work with dental teams similar to the way physicians’ assistants work with medical teams. Along with providing education and preventive services, they are also able to perform common dental procedures such as filling cavities and, in limited cases, removing teeth.

Through the off-site supervision of a dentist, dental therapists can also deliver care in settings that better meet the needs of underserved communities like remote clinics, schools, and senior centers.

Where employed, dental therapists enable dentists and community clinics to see more Medicaid patients, reduce patient wait times, and divert emergency room usage.

Dental therapists work as part of the existing dental team and may also be dually educated as a dental therapist/dental hygienist.

A Growing Profession

Dental therapists have been practicing in the US for more than ten years — improving access to dental care for underserved communities in Alaska since 2005, and in Minnesota since 2011.

Dental therapists were recently authorized to work in Vermont and Maine. Oregon and Washington have hired dental therapists as part of demonstration projects within tribal communities, and close to a dozen more states are considering authorizing the providers.

The Commission on Dental Accreditation has officially recognized dental therapy as a profession and adopted national education standards for dental therapists in 2015.

A Cost-Effective Solution

Dental therapists are a cost-effective way to increase access to critically-needed dental care. Using dental therapists reduces costly emergency room visits, creates good jobs and helps dentists expand their small businesses at no additional cost to the state.

Building a Culturally Competent Workforce

Dental therapists often work in their own communities, allowing them to establish a high level of trust with patients improving their experiences and outcomes. In just over a decade, leaders in Alaska Native communities have built a group of highly skilled American Indian/Alaska Native dental therapists who share the language and culture of the more than 45,000 people they serve.

Dental therapists have some overlap with dental hygienists but also work complementary to them, performing restorative procedures including the drilling and filling of cavities and limited tooth extractions, all under dentist supervision.
