Dental care has traditionally been financed and delivered separately from medical care. This is despite the Surgeon General’s report in 2000 that emphasizes the importance of oral health to whole body health. Now, new data show the consequences of the approach taken in U.S. health care policy to oral health.
Medicaid Children Seeing Big Gains in Access to Dental Care
The American Dental Association Health Policy Institute (HPI) recently launched The Oral Health Care System: A State-By-State Analysis. This first-of-its-kind data repository brings together data from multiple sources related to oral health and is meant to serve policy makers and researchers. One of the most significant findings from these data is that access to dental care has been increasing steadily among Medicaid children for more than a decade.
Nationally, the percent of Medicaid children who visited a dentist within the past twelve months went from 29% in 2000 to 48% in 2013, the most recent year for which data are available. What is striking is that the trend is remarkably widespread across states, with all but one state experiencing gains over this time frame. As a result, the gap in dental care utilization between Medicaid- and privately-insured children has been shrinking steadily. In fact, it narrowed in every single state for which we have data between 2005 and 2013 (see figure below). There are two states – Hawaii and Texas – where there is actually a “reverse gap”: children enrolled in Medicaid are more likely to visit a dentist than children who have private dental benefits. Moreover, this progress has all been happening during a time when the number of children enrolled in Medicaid and the Children’s Health Insurance Program (CHIP) has been rising steadily. In 2013, nearly four out of ten children in the U.S. were enrolled in Medicaid or CHIP compared to two out of ten in 2000.

Trends for Adults Are Much Different
In contrast, the trends for adults are very different. The gap in dental care use between Medicaid- and privately-insured adults is much wider than it is for children and has actually increased in several states in recent years. Adults – especially Millennials – are nearly three times more likely than children to report avoiding dental care they need because of cost. In fact, one out of four low-income adults report that they have avoided dental care they needed in the past year due to financial reasons.
Dental care presents affordability challenges to adults to a much greater degree than any other type of health care service. Emergency room visits for dental conditions in the U.S. are on the rise, a trend that is being driven entirely by young adults. Even among adults with private dental benefits, dental care use is declining in most states and the number one reason adults with private dental benefits do not visit the dentist is cost.
The barriers to dental care that adults face are leading to some troubling physical, social, and emotional effects. New data show that more than one out of three low-income adults say they avoid smiling and 17 percent report difficulty doing usual activities because of the condition of their mouth and teeth. Nearly one out of four low-income adults and 14 percent of all adults report that their oral health issues have led them to reduce participation in social activities.
Where Do We Go From Here?
Looking forward, policymakers and the research community ought to focus on three things to address some of the key challenges facing the U.S. oral health care system.
First, there needs to be a continued and sustained focus on implementing evidence-based policies when it comes to access. The states with the largest gains in access to dental care among Medicaid children over the past decade are those that implemented comprehensive, multi-pronged reforms. For example, Connecticut, Texas, and Maryland reformed their Medicaid programs by focusing on provider and Medicaid beneficiary outreach, provider reimbursement increases,innovations in care delivery models, and streamlined administrative procedures and saw remarkable improvements. It is important to note that the improvements in access to dental care in these three states, as well as others, did not involve any major increase in the number of dental care providers. In fact, there is strong evidence that there is significant excess capacity in the dental care system today. Nationwide, one out of three dentists report they are “not busy enough and can see more patients” suggesting that policymakers ought to focus on interventions that leverage existing unused capacity.
Second, there need to be a rethink of how oral health is defined and measured. The current focus of many government agency data collection efforts, for example,is to measure the presence and severity of dental disease and the frequency and type of dental care services people use. There is very little emphasis, in contrast, on measuring the contribution of oral health to physical, social, and emotional well being. These are the ultimate outcomes of interest that any dental care delivery system ought to be designed around. The new measures of oral health status recently developed by HPI are a significant advancement in this area but are meant to be a starting point for others, including the Centers for Disease Control and Prevention and the Agency for Healthcare Research and Quality, to build on. A robust oral health status measurement system would also enable a shift toward outcomes-based delivery and reimbursement models, a critical future direction in health care in the United States.
Third, policy makers need to reconsider how dental care for adults is handled in state and federal policy. Within Medicaid, adult dental benefits are optional and most states provide only basic coverage. Under the Affordable Care Act, dental care for adults is not considered “essential” and thus, dental benefits coverage is not part of the individual mandate. Implementing a comprehensive dental benefit for Medicaid adults in the 22 states that currently lack one is estimated to cost $1.6 to $1.8billion per year. The estimated state portion of this bill translates to about 1 percent of total Medicaid spending. Compare this to the $1.6 billion spent each year on hospital emergency room visits for dental conditions, one third of which is paid for by Medicaid. Newly published research from the NBER suggests that the dental care system has the capacity to absorb the spike in demand for dental care arising from large-scale expansions of dental benefits to Medicaid adults. There are also numerous state experiences to draw on that serve as good practices in managing adult dental benefits in Medicaid. Beyond Medicaid, insurers are approaching dental benefits for children and adults differently within the health insurance marketplaces. While more and more private medical insurance plans in the health insurance marketplaces are covering dental benefits for children, there are far fewer options for adults. This is despite the fact that dental care is a high priority among adults, especially young adults,who are shopping for health insurance.
As a former U.S. Surgeon General said, “you can’t be healthy without good oral health.” There is emerging evidence that oral health is related to conditions outside of the mouth, like diabetes, pregnancy, and even mental health. Health care policy in the United States clearly emphasizes the importance of oral health for children. It might be time to reconnect mouth and body for adults.
