Does Occupational Licensing Impact Access to Dental Care?

Executive Summary

As of 2018, the Bureau of Health Workforce had identified nearly 6,000 areas in the US with inadequate professional dental care. Around 54 million people live in those shortage areas, and it is estimated that nearly 10,000 additional practitioners are necessary to meet their needs. This paper explores the academic literature on occupational licensing to understand whether licensing laws are contributing to this shortage and if reforming those laws could increase access to dental care.

Occupational licensing limits access to dental care

Licensing laws are intended to safeguard consumers from being harmed by ill-qualified or undertrained practitioners. In the field of dentistry, this means that in addition to requiring dentists to have a license, states also place a number of restrictions on mid-level practitioners like dental hygienists. Mid-level practitioners are qualified to perform preventative dental procedures like cleanings and sealants, but licensing laws limit their ability to perform these services. As a result, the number of services that can be provided outside of dental offices shrinks, raising the price of dental care. Of US adults who did not visit the dentist in the past year, over half pointed to high fees as their reason for not seeking care.

Licensing also reduces the number of dental service providers available to consumers because it acts as a barrier to employment. Further, state-specific licensing makes it harder for dentists to relocate to states with higher demand for dental services, as different states have different requirements for licensure.

Empowering dental assistants can improve access to dental care

  • Because they require less training than dentists, mid-level providers offer less complicated services at lower costs.
  • If restrictions on mid-level providers are reduced, the number of providers performing those services would likely increase, expanding access to dental care.

Occupational licensing reforms in other industries have lowered costs, improved opportunities for workers, and increased consumer access to services. Changes in the dental field could have similar results. In light of this, policymakers should focus on pursuing reforms to current occupational licensing laws, such as expanding autonomy for mid-level providers.

Introduction

Occupational licensing laws—entry regulations placed on professions by state and local government agencies—affect broad swaths of the American economy. These regulations require practitioners to obtain state-certified licenses before they can practice their professions legally.1Department of the Treasury Office of Economic Policy, Council of Economic Advisers, and Department of Labor, Occupational Licensing: A Framework for Policymakers, July 2015, https://obamawhitehouse.archives.gov/sites/default/files/docs/licensing_report_final_nonembargo.pdf. Licensing requirements affect all kinds of professional work, from hairdressers and plumbers to doctors and lawyers.2Thomas G. Moore,“The Purpose of Licensing,” Journal of Law and Economics (1961), p.103, https://www.jstor.org/stable/724908?seq=11#metadata_info_tab_contents.

Although the occupations licensed and the stringency of licensing rules vary by location, every state requires that dentists be licensed.3Morris M. Kleiner and Kyoung Won Park, “Battles among Licensed Occupations: Analyzing Government Regulations on Labor Market Outcomes for Dentists and Hygienists,” National Bureau of Economic Research, 2010, https://www.nber.org/papers/w16560.pdf. Dental licensing is meant to protect consumers and ensure that only qualified practitioners perform technical procedures, but licensing may actually restrict the availability of dental-care services to consumers.4 Josh T. Smith, Vidalia Freeman, and Jacob M. Caldwell, How Does Occupational Licensing Affect U.S. Consumers and Workers?, Center for Growth and Opportunity at Utah State University, December 2018, https://www.growthopportunity.org/research/rif/how-does-occupational-licensing-affect-u-sconsumers-and-workers/.

There is a need in the United States for greater access to dental and oral health services. As of 2018, over five thousand three hundred dental Health Professional Shortage Areas had been identified nationwide. Nearly fifty-four million people live in those shortage areas, and the Bureau of Health Workforce estimates that almost ten thousand additional practitioners are needed to meet their needs.5Bureau of Health Workforce, Health Resources and Services Administration (HRSA), US Department of Health & Human Services, Third Quarter of Fiscal Year 2019 Designated HPSA Quarterly Summary, June, 2019, https://data.hrsa.gov/Default/GenerateHPSAQuarterlyReport

Occupational licensing rules likely are contributing to this shortage as they often prevent mid-level dental-care providers, such as dental therapists and dental hygienists, from performing low-risk, non-invasive procedures without supervision by a licensed dentist.6American Dental Hygienists’ Association, Dental Hygiene Practice Act Overview: Permitted Functions and Supervision Levels by State, January 2019, https://www.adha.org/resources-docs/7511_Permitted_Services_Supervision_Levels_by_State.pdf. According to occupational licensing research, such restrictions may shrink the available pool of dental-care providers and increase the cost of receiving those procedures.7Morris M. Kleiner and Robert T. Kudrle, “Does Regulation Affect Economic Outcomes? The Case of Dentistry,” Journal of Law and Economics 43, no. 2 (October 2000): 547–82, https://doi.org/10.1086/467465; see also Smith, Freeman, and Caldwell, How Does Occupational Licensing Affect U.S. Consumers and Workers? For example, teeth cleaning sometimes is restricted to the practice of dentistry despite its low risk.8American Dental Hygienists’ Association, Dental Hygiene Practice Act Overview Not only do independent dental therapists and hygienists have the ability to perform these services, but evidence in occupational licensing literature suggests that the quality of care provided is on par with that of supervised professionals.9 James R. Freed, Dorothy A. Perry, and John E. Kushman, “Aspects of Quality of Dental Hygiene Care in Supervised and Unsupervised Practices,” Journal of Public Health Dentistry 57, no. 2 (1997): 68-75. See also Phillips E, Shaefer HL. “Dental therapists: evidence of technical competence.” Journal of Dental Research no. 92 (2013):11S–15S.

This research-in-focus piece examines existing research on occupational licensing with specific emphasis on aspects that relate to dental care. We first highlight the need for accessible dental care. We then examine the effect of occupational licensing on access to dental care, specifically focusing on how it impacts quality, cost, and availability. We explore how mid-level providers may expand access to care, and we end with a conversation about reforming occupational licensing laws. Our key finding is that reforming laws that limit access to mid-level dental-care providers could reduce dental costs and provide more opportunities for Americans to receive dental care.

The Importance of Access to Dental Care

The quality of dental care available to Americans has improved dramatically over the past fifty years, yet disparities remain.10Caswell A. Evans and Dushanka V. Kleinman, “The Surgeon General’s Report on America’s Oral Health: Opportunities for the Dental Profession,” Journal of the American Dental Association 131, no. 12 (2000): 1721–28.​ About 36 percent of children in low-income households suffer from untreated decay in their primary (baby) teeth compared to about 17 percent of children in wealthier households.11Ibid., 63. The Centers for Disease Control and Prevention found that Hispanics and African Americans had rates of untreated tooth decay almost twice that of whites—36 and 42 percent, respectively, versus 22 percent.12Bruce A. Dye, Gina Thornton-Evans, Xianfen Li, and T. Iafolla, Dental Caries and Tooth Loss in Adults in the United States, 2011-2012, US Department of Health and Human Services, Centers for Disease Control and Prevention, National Center for Health Statistics, 2015. Minorities also account for a significantly larger fraction of low-income households than whites.13 Henry J. Kaiser Family Foundation, 2017, “Poverty Rates by Race/Ethnicity,” https://www.kff.org/other/state-indicator/poverty-rate-by-raceethnicity/?currentTimeframe=0&sortModel=%7B%22colId%22:%22Location%22,%22sort%22:%22asc%22%7D.

According to a survey conducted by the American Dental Association, one in five low-income adults admit to poor oral health and 39 percent of respondents say that life is “less satisfying due to the condition of [their] mouth and teeth.”14American Dental Association and Health Policy Institute, Oral Health and Well-Being in the United States, 2015, https://www.ada.org/~/media/ADA/Science%20and%20Research/HPI/OralHealthWell-Being-StateFacts/US-OralHealth-Well-Being.pdf?la=en. Despite that evidence, the report states that 80 percent of low-income adults and 63 percent of all adults had not visited a dentist within the last year.15Ibid. A more recent estimate from the Centers for Disease Control and Prevention shows that 35 percent of adults had not seen a dentist within the previous year.16National Center for Health Statistics, Oral and Dental Health, Centers for Disease Control and Prevention, May 3, 2017, https://www.cdc.gov/nchs/fastats/dental.html.

The primary reason people give for not visiting a dentist is the cost of services.17American Dental Association and Health Policy Institute, Oral Health and WellBeing in the United States. Of adults who had not visited a dentist in the last year, 59 percent pointed to high fees for dental care as the main reason for not seeking oral health services, as shown in Figure 1.18 Ibid.

The Role of Occupational Licensing in Access to Dental Care

Dentists, attorneys, and physicians were some of the earliest occupations to be licensed by states. As of 1888, 50 percent of states required dentists to be licensed.19Moore, “The Purpose of Licensing,” 103. By 1935, every state required a license to practice dentistry.20Kleiner and Park, “Battles among Licensed Occupations,” 2.

Licensing rules are meant to protect consumers from predatory or incompetent professionals in service industries.21Morris Kleiner, “Occupational Licensing,” Journal of Economic Perspectives (2000), p. 192, https://pubs.aeaweb.org/doi/pdfplus/10.1257/jep.14.4.189. Occupational licensing works by creating a barrier to entry into a field.22Kleiner and Kudrle, “Does Regulation Affect Economic Outcomes?” By imposing requirements such as educational requirements (or training), tests, and fees, regulators intend to ensure each certified provider is capable of performing the services they advertise.

Economists in recent decades have invested substantial effort in identifying the effects of occupational licensing regulations. The studies generally examine the costs of licensing—both to consumers and to laborers who must become licensed —their impact on quality, their impact on wages, and their impact on the overall size of the licensed workforce. Dentistry occupies a different space from that of many licensed occupations because of the risk and complexity of dental procedures, but economists have found that licensing in dentistry has produced similar outcomes to other industries. Stricter licensing tends to reduce the supply of labor to the affected occupations and raises prices without always increasing the quality as intended.23 Ibid. See also Kleiner, “Occupational Licensing.”

Effect of Licensing on Quality and Cost

At its core, licensing is meant to ensure high quality of service for consumers. Despite these intentions, it is unclear whether occupational licensing actually leads to better results. The Mercatus Center published a review of the findings of nineteen studies examining occupational licensing and related outcomes. According to the researchers, only three of the studies found that occupational licensing regulations had a positive effect on outcomes for consumers, whereas four of them found negative impacts related to occupational licensing. Most of the studies—63 percent— found that the results were unclear, mixed, or neutral.24Patrick McLaughlin, Matthew D. Mitchell, and Anne Philpot, “The Effects of Occupational Licensure on Competition, Consumers, and the Workforce,” Mercatus Center at George Mason University, November 2017, https://www.mercatus.org/publications/study-american-capitalism/effects-occupationallicensure-competition-consumers-and.

One study from that review was a paper by economists Morris Kleiner and Robert Kudrle. Their paper examined the oral health of Air Force recruits from across the country and compared the recruits’ health to the difficulty of becoming a licensed dentist in each of the states. Their findings suggest that stricter licensing requirements for dentists did not improve oral health outcomes but did raise prices of dental services.25Kleiner and Kudrle, “Does Regulation Affect Economic Outcomes?” That finding implies that stricter licensing requirements in general could increase costs without raising quality.

Another study, focused on the effects of state licenses for child care providers, finds that licensing did improve the quality of care that children received. However, according to the authors, licensing also “significantly reduces the number of operating child care centers, especially in lower-income markets,” meaning that only children in more affluent areas where centers remained benefited from the quality improvements.26V. Joseph Hotz and Mo Xiao, “The Impact of Regulations on the Supply and Quality of Care in Child Care Markets,” American Economic Review 101, no. 5 (2011): 1775–1805, https://pubs.aeaweb.org/doi/pdfplus/10.1257/aer.101.5.1775.

A review the Obama administration produced finds that in nine of eleven studies, “significantly higher prices accompanied stricter licensing.”27Department of the Treasury Office of Economic Policy, Council of Economic Advisers, and Department of Labor, Occupational Licensing, 14. Likewise, all nineteen papers reviewed in the study by the Mercatus Center find that licensure increases prices.28McLaughlin, Mitchell, and Philpot, “The Effects of Occupational Licensure on Competition, Consumers, and the Workforce.”As mentioned above, the cost of dental services is the single most cited reason why individuals do not visit the dentist. Removing some of these barriers could help lower prices and thus increase access to dental care.

Effect of Licensing on Availability

Because licensing rules act as barriers to entry into licensed occupations, the supply of new professionals is reduced and competition between providers is less vigorous. The main beneficiaries of such barriers to entry are the licensed practitioners already in the market. Using labor-market data from the Census Bureau and data from previous work, economists Peter Blair and Bobby Chung created a model that examined occupations that were licensed in one state but not in a neighboring state. They find that in states with occupational licensing, the number of laborers in that industry was 17–27 percent lower, on average, suggesting that licensing has a negative and significant effect on the supply of labor in licensed occupations.29Peter Q. Blair and Bobby W. Chung, “How Much of Barrier to Entry Is Occupational Licensing?” National Bureau of Economic Research, December 2018, https://www.nber.org/papers/w25262.

A study by economists Janna Johnson and Morris Kleiner finds that individuals in occupations with state-specific licensing requirements have an interstate migration rate 16 percent lower than that of similarly licensed individuals who have the option of passing a national exam recognized by state licensing boards.30Janna E. Johnson and Morris M. Kleiner, “Is Occupational Licensing a Barrier to Interstate Migration?”, Federal Reserve Bank of Minneapolis Research Division and National Bureau of Economic Research, December 2017, https://doi.org/10.21034/sr.561. Furthermore, they point out, dentists, dental hygienists, and social workers have very low interstate migration rates compared to the other occupations studied. Although national exams are administered for all three of those occupations, the authors point to state-specific courses for social workers and clinical exams for dental professionals as possible causes of the relatively low rates of interstate migration observed in those occupations.31Johnson and Kleiner, “Is Occupational Licensing a Barrier to Interstate Migration?” Such barriers to changing practice locations can reduce the flow of dental professionals to areas where they are needed, exacerbating existing accessibility issues.

How Mid-level Providers Can Improve Access to Dental Care

Mid-level providers are professionals in health care fields that can perform many of the same functions performed by doctors and dentists, but they require less training and therefore offer services at lower costs.32Mathu-Muju and Mathu-Muju, “Dental Therapists.”

Table 1: Provider Education Costs

Source: Jay W. Mathu-Muju and Kavita R. Mathu-Muju, “Dental Therapists: Improving Access to Oral Health Care for Underserved Children,” American Journal of Public Health (June 2014), https://doi.org/10.2105/AJPH.2014.301895.

Reforms that allowed for mid-level providers in the healthcare industry and subsequent policy changes that have widened their scope of practice—the number of procedures they are licensed to perform—have led to better outcomes for both consumers and service providers. Research suggests that laws expanding the scope of practice for physician assistants and nurse practitioners have led to higher wages for mid-level practitioners, less expensive procedures for consumers, and an overall increase in access to health care.33Roderick S. Hooker and Christine M. Everett, “The Contributions of Physician Assistants in Primary Care Systems,” Health and Social Care in the Community 20, no. 1 (August 2011), https://doi.org/10.1111/j.1365-2524.2011.01021.x; and M. Kleiner, A. Marier, K. Park, and C. Wing, May 2016, “Relaxing Occupational Licensing Requirements: Analyzing Wages and Prices for a Medical Service,” Journal of Law and Economics 59, no. 2 (May 2016): 261–91, https://doi.org/10.1086/688093.

Dentistry has seen similar reforms with the incorporation of mid-level providers, but a number of opportunities still remain for lowering occupational licensing barriers and increasing consumer access.

Table 1 provides a breakdown of the average cost and length of schooling for dentists and related mid-level dental care providers. The latter’s lower level of required training means mid-level service providers often are not qualified to perform complex and in-depth procedures performed by specialists. They can, however, provide less complicated procedures at a lower cost.34Mathu-Muju and Mathu-Muju, “Dental Therapists.” Many of those procedures include preventative care, such as teeth cleanings and sealants, which can protect consumers from more expensive emergency procedures such as tooth extractions and root canals.35Minnesota Department of Health, February 2014, Early Impacts of Dental Therapists in Minnesota, Minnesota Department of Health Minnesota Board of Dentistry Report to the Minnesota Legislature 2014, 1–2, https://www.health.state.mn.us/data/workforce/oral/docs/dtlegisrpt.pdf. See also Member Benefits, “Dental Costs with and without Insurance,” April 6, 2015, https://memberbenefits.com/dental-costs-with-and-without-insurance/.

Dental hygienists, whose role typically includes performing routine teeth cleanings and other preventative-care procedures, are the most common mid-level providers of dental care.36 Bureau of Labor Statistics, “Occupational Employment and Wages, May 2017 29-2021 Dental Hygienists,” March 30, 2018, https://www.bls.gov/oes/2017/may/oes292021.htm; Doreen K. Naughton, “Expanding Oral Care Opportunities: Direct Access Care Provided by Dental Hygienists in the United States,” Journal of Evidence Based Dental Practice (June 2014), https://doi.org/10.1016/j.jebdp.2014.04.003. They are limited by scope-of-practice laws that dictate the number of hours required to receive and maintain certification, what procedures hygienists are allowed to perform, and the type of supervision required.37Richard J. Manski, Diane Hoffmann, and Virginia Rowthorn, “Increasing Access to Dental and Medical Care by Allowing Greater Flexibility in Scope of Practice,” American Journal of Public Health 105, no. 9 (2015): 1755–62. Over the past few decades, states have begun to reduce those restrictions to make dental-hygienist care more accessible to consumers by allowing patients to have direct access to dental hygienists.38Margaret Langelier, Tracey Continelli, Jean Moore, Bridget Baker, and Simona Surdu, “Expanded Scopes of Practice for Dental Hygienists Associated with Improved Oral Health Outcomes for Adults,” Health Affairs 35, no. 12 (2016): 2207–15. See also American Dental Hygienists’ Association, “Direct Access,” June 27, 2019, https://www.adha.org/direct-access. Those reforms mean that dental hygienists can treat patients without the authorization or supervision of a licensed dentist.39American Dental Hygienists’ Association, “Direct Access 2018,” April 2018, https://www.adha.org/resources-docs/7524_Current_Direct_Access_Map.pdf. As of April 2018, forty-two states allowed patients direct access to dental hygienists in some form.40American Dental Hygienists’ Association, “Direct Access 2018.”

The types of services that dental hygienists can provide vary by state. Colorado and Maine, for example, impose few limits in their scope-of-practice laws, whereas many southeastern states, such as Alabama and Mississippi, have enacted much more restrictive scope-of-practice laws.41Naughton, “Expanding Oral Care Opportunities”; Margaret Langelier, Bridget Baker, and Tracey Continelli, “Development of a Dental Hygiene Professional Practice Index by State,” 2016, Center for Health Workforce Studies, http://www.chwsny.org/wp-content/uploads/2016/12/SOP_Policy_Brief_2016-1.pdf. Figure 2 illustrates the wide variation in scope-of-practice laws throughout the United States. Each state is given a score based on the level of autonomy of dental hygienists.

A number of studies suggest that expanding the scope of practice for dental hygienists expands access to primary dental care. One report from the National Center for Health Workforce Analysis finds that broader scope of practice for dental hygienists is “significantly and positively correlated” with more individuals receiving oral health care, including larger percentages of individuals getting their teeth cleaned and visiting the dentist.42Health Resources and Service Administration, “The Professional Practice Environment of Dental Hygienists in the Fifty States and the District of Columbia,” National Center for Health Workforce Analysis, Bureau of Health Professions, April 2004, https://docplayer.net/13728482-The-professional-practice-environmentof-dental-hygienists-in-the-fifty-states-and-the-district-of-columbia-2001-april-2004.html; Catherine H. Bersell, “Access to Oral Health Care: A National Crisis and Call for Reform,” Journal of Dental Hygiene 91, no. 1 (February 2017), http://jdh.adha.org/content/jdenthyg/91/1/6.full.pdf. Another report from the National Center for Health Workforce Studies finds similar results, as greater autonomy for dental hygienists is positively correlated with access to oral health services and oral health.43Paul Wing, Margaret H. Langelier, Tracey A. Continelli, and Ann Battrell, “A Dental Hygiene Professional Practice Index (DHPPI) and Access to Oral Health Status and Service Use in the United States,” Journal of Dental Hygiene 79, no. 2 (Spring 2005), http://jdh.adha.org/content/jdenthyg/79/2/10.full.pdf.

Much as past reforms led to higher wages for nurse practitioners and lower costs for consumers, reducing licensing restrictions on dental hygienists could result in better outcomes for both hygienists and their patients.44Hooker and Everett, “The Contributions of Physician Assistants in Primary Care Systems”; and Kleiner, et al., “Relaxing Occupational Licensing Requirements.”

Dental therapists, another type of mid-level dental care provider, recently have begun to practice in the United States. Dental therapists offer preventative care similar to dental hygienists, but they also can offer restorative or permanent procedures, including filling cavities or performing simple extractions. As of March 2019, dental therapists were allowed to practice in some form in eight states.45 John Grant and Kristen Mizzi Angelone, “Michigan Becomes 8th State to Authorize Dental Therapists,” Pew Charitable Trusts, December 31, 2018, https://www.pewtrusts.org/en/research-and-analysis/articles/2018/12/31/michiganbecomes-8th-state-to-authorize-dental-therapists. Figure 3 outlines in orange the states where dental therapists practice. The same figure also shows the severity of Health Professional Shortage Areas in each state. The lighter the color, the greater the need for dental professionals.

Dental therapists have thus far been allowed to practice mainly in states already home to large numbers of Health Professional Shortage Areas. The main driver for allowing dental therapists to practice in such states has been policy makers’ desire to increase access to dental care.4646 The reforms have notably increased the availability of dental services to underserved populations.47 Minnesota Department of Health, February 2014, Early Impacts of Dental Therapists in Minnesota, 1–2.

In 2005, Alaska was the first state to allow dental therapists to practice, but its scope of practice was limited to Native American communities.48David A. Nash, “Adding Dental Therapists to the Health Care Team to Improve Access to Oral Health Care for Children,” Academic Pediatrics 9, no. 6 (November-December 2009): 446–51, https://doi.org/10.1016/j.acap.2009.08.005. A 2017 report conducted at the University of Washington asked whether differences in access to preventative care and overall dental health existed between Yukon Kuskokwim communities in which dental therapists practiced and areas in which they did not. The study finds that the members of those communities in which dental therapists worked received more preventative care and had fewer teeth extractions—indications of greater overall health.49 D. L. Chi, D. Lenaker, L. Mancl, M. Dunbar, and M. Babb, “Dental Utilization for Communities Served by Dental Therapists in Alaska’s Yukon Kuskokwim Delta: Findings from an Observational Quantitative Study,” University of Washington, August 11, 2017, http://faculty.washington.edu/dchi/files/DHATFinalReport.pdf.

To address the oral health problems of low-income, minority, and elderly individuals, Minnesota passed a law in 2009 that allows dental therapists to practice in settings that focus on treating low-income patients or in Health Professional Shortage Areas.50Minnesota Department of Health, Early Impacts of Dental Therapists in Minnesota, 5. A Minnesota Department of Health report examines the early impacts of the thirty-two dental therapists who were licensed as of February 2014, finding that many clinics saw reductions in waiting times for patients and an increase in new patients directly attributable to the addition of a dental therapist to the team.51Minnesota Department of Health, Early Impacts of Dental Therapists in Minnesota, 1. About one-third of the patients surveyed by the study’s authors reported having shorter waits for treatment because their local clinic had hired a dental therapist.52Minnesota Department of Health, Early Impacts of Dental Therapists in Minnesota, 1. Reducing barriers to entry for mid-level providers may have a positive impact on consumer health.

Reforming Scope-of-Practice Laws to Increase Access to Dental Care

A need for broader access to dental care at lower prices is evident. Reforming occupational licensing rules in other industries has increased social welfare. Similar changes in the dental field could expand access to dental care for poor and underserved communities while also lowering the cost of care for everyone. Many of the changes are as simple as expanding scope-of-practice laws for mid-level providers, especially in states where licensing laws are currently restrictive.

As lawmakers pursue occupational licensing reforms within their states, it is important that they consider highly specialized fields like dentistry in addition to low-skilled occupations. The existing academic literature on the issue suggests that broad welfare improvements can be achieved when licensed professionals are given more freedom to practice.
