Ohio is considering a proposal to improve access to dental care for all Ohioans and lower unnecessary barriers by allowing dental therapists (DTs) to provide needed care to Ohio patients.
According to the Ohio Department of Health (ODH), in 2009 there were 56 dental health professional shortage areas in the state. Today, there are 88. ODH also found the dental care shortage falls hardest on Ohio’s children. According to ODH, 17 percent of Ohio’s third graders have untreated tooth decay. Children in low income households and those without private insurance have almost twice the number of untreated cavities and toothaches.
Dental pain has even been found to place a burden on emergency rooms. According to Pew Charitable Trusts, more than two million people in 2012 reported to local emergency rooms for dental pain, costing taxpayers $1.6 billion, with Medicaid’s share totaling $520 million. Dental health is important and overlooked; 101 people died in hospital emergency departments from 2008 to 2011 due to preventable dental disease.
Strict licensing standards have become a significant barrier to entry in many fields, including the dental industry. Supporters of strict state licensing standards argue they assure quality, but critics say the arduous and often expensive licensing process harms the dental market by hindering entry for new providers, thereby impeding the market competition needed to lower costs and improve access for patients.
To address dental health shortages, states across the country have started to examine ways to better utilize non-dentist oral health care professionals, such as dental therapists and hygienists. Dental therapists can perform up to 95 services and procedures, compared to about 40 performed by hygienists and 30 performed by dental assistants.
The Ohio proposal would create a new mid-level care license for dental therapists, allowing DTs to practice under the supervision of a dentist. Expanding DTs’ role would free up time for dentists to focus on complicated cases and provide basic care to more patients. The proposal would allow a DT to perform procedures such as basic tooth extractions, cleanings, fillings, and X-rays.
While general supervision, where a DT can practice without a dentist being physically present, is the ideal arrangement, this bill does provide a reasonable path toward greater autonomy for DTs. The proposal would allow a supervising dentist to draft a written practice agreement detailing exactly what a dental therapist can do without a dentist being physically present. To qualify for the agreement under the proposed legislation, a DT would have to successfully complete 400 hours of clinical practice under the direct supervision of a dentist.
If written agreements are required for dental therapists to practice independently, then the only effective arrangement would be one in which an agreement is written as broadly as possible and does not require overly excessive fees. Similar agreements governing how nurse practitioners may function have acted as a barrier to entry because they are overly expensive.
According to the Pew Charitable Trusts, midlevel providers are authorized to provide routine preventive and restorative care in more than 50 nations. “Compared to dentists, dental therapists perform fewer procedures, require less training, and command lower salaries. Research has confirmed that they provide high-quality, cost-effective routine care and improve access to treatment in parts of the country where dentists are scarce.”
Some opponents of expanding the scope of practice in dentistry argue it will result in worsening quality of care. In testimony before the North Dakota House Human Services Committee, Michael Hamilton, then a research fellow for The Heartland Institute, argued these concerns are unfounded. “If therapists obtain licensure in North Dakota, dentists would remain responsible for the quality of treatment patients receive in their offices from any and all employees, whether dental hygienists, dental assistants, associate licensed dentists, or dental therapists. Therefore, to block dental therapy based on concern for quality of treatment is to doubt the quality, competence, and judgment of licensed dentists.”
Permitting dental therapists to practice without a dentist physically present would help to close gaps in dental care access and help ensure patients get the preventive and restorative treatment they need.

Dental Utilization for Communities Served by Dental Therapists in Alaska’s Yukon Kuskokwim Delta: Findings from an Observational Quantitative Study
This study from the University of Washington examines whether dental utilization rates in Alaska Native communities were associated with the number of dental therapist treatment days and quantifies differences in dental utilization rates between communities without dental therapist treatment days and those communities with the highest number of dental therapist treatment days.
The Case for Licensing Dental Therapists in North Dakota
In this Policy Brief, Michael Hamilton, Bette Grande, and John Davidson ask North Dakota lawmakers: “Does licensing dental therapists in North Dakota pose a risk to public health great enough to justify depriving (1) dentists of their right to employ and supervise dental therapists and (2) patients of their right to access providers of their choice?” They argue the answer is clearly “no.” Far from jeopardizing the public health, licensing dental therapists would likely expand patient access to high-quality oral care services and reduce oral care costs in North Dakota.
States Consider Authorizing Dental Therapy to Expand Access
Mary Tillotson writes in Health Care News about the movement by several states to consider allowing dental therapists additional power to treat patients. “Millions of rural Americans lack access to proper dental care, a shortage 12 states are considering filling by authorizing dental therapy, an oral-care-industry profession roughly equivalent to a physician assistant or nurse practitioner,” wrote Tillotson.

How Reforming Licensing Laws Can Help Fix America’s Dentist Shortage
Eric Boehm, a reporter at Reason.com, examines the dentist shortage and argues in favor of reforming state dental licensing laws for dental therapists as a potential solution. “Children’s Dental Services … treats about 30,000 patients each year, mostly from the Twin Cities’ Hispanic, Hmong and Somali immigrant communities. The dental therapy model was first adopted by nonprofits and community clinics to lower costs, says Karl Self, the director of the University of Minnesota’s therapy program. But now, Dr. Self adds, private practices are hiring dental therapists, too. ‘We’re seeing that dental therapists can add value to the overall oral health team,’ he says.”

Pew Charitable Trust: Dental Campaign
Pew Charitable Trust has been providing research and analysis to encourage state lawmakers to allow dental therapists in their states to ensure patients have greater access to preventive and restorative treatment services. “Pew’s dental campaign works to close gaps in dental-care access by increasing the number of available providers and expanding the reach of preventive services through the use of dental sealant programs in high-need schools. Research shows that such programs are a valuable, cost-effective way to treat the children most at risk of tooth decay.”
