A New Type of Dental Provider


In early 2009, the Minnesota legislature took a step toward improving dental service access for low-income residents. Surprisingly, the law does not concern increasing dental provider reimbursement rates or improving the quality of school-based oral health programs, but rather paves the way for the training of a new type of dental provider known as a dental therapist. A two-and-a-half-year program that would follow a traditional 4-year bachelor’s degree, the dental therapist program at the University of Minnesota trains individuals to be the dental version of a physician’s assistant. Dental therapists will be trained to provide “relatively simple services such as filling cavities, instructing patients in dental hygiene and performing dietary evaluations and oral cancer screenings.” (1)

While dental therapists will be able to practice outside of dentists’ offices, their work will nonetheless be supervised by dentists who may be off-site. The University of Minnesota program will place each of its nine enrollees into dental professional shortage areas throughout the state with the hope that the reduced cost of their services (as compared to that of dentists) will extend the reach of access to those in lower income brackets.

Minnesota is not the only state which has shown interest in exploring the possibility of new types of dental providers. Since 2003 the state of Alaska has made use of dental health aide therapists (or DHATs) to provide needed services for residents who may be a boat or plane ride away from the nearest practicing dentist. Although the original DHATs were Alaska residents trained in New Zealand who returned to their homes to practice, since 2007 the DHATs have been trained in the U.S. thanks to collaboration between the University of Washington School of Medicine Physician Assistant Training Program and the Alaska Native Tribal Health Consortium.

The fundamental question surrounding the dental therapist model has increasingly become one of quality. The American Dental Association (ADA) has noted that the scope of procedures performed by dental therapists should be limited as their professional training does not match that of a dentist who commits to a minimum of 4 years of professional study. Nonetheless, the Alaska program’s utilization statistics “suggest that dental therapists are improving access to year-round oral health care for individuals who previously could see a dentist only a few weeks each year.” (2) While more extensive evaluation remains to be done, it seems clear that if a balance between practice capabilities and supervision is established, the dental therapist may offer an effective means of providing the most vulnerable populations with quality dental care.
