When most people think of health care, they picture doctor visits, vaccines, or maybe even mental health services. But there’s one vital piece of the puzzle that’s often left out: the dentist. Oral health is frequently treated as separate from “typical” health care, despite the fact that your mouth often reflects and affects your overall health. Dentistry is far more than just cleanings and cavities. It plays a critical role in preventing chronic disease, reducing emergency room visits, and even shaping self-esteem. Yet dental care is often inaccessible, unaffordable, and excluded from key health systems and insurance coverage. This gap doesn’t just hurt teeth; it affects lives.
Right now, nearly half of the world’s population (about 3.5 billion people) suffers from oral diseases like tooth decay, gum disease, and oral cancers. To put that in perspective, that’s more than triple the global burden of mental health conditions and almost seven times the number of people affected by heart disease. About three-quarters of people suffering from oral diseases live in low and middle-income countries, a stark reminder that oral health is a global equity issue. Dental care is the most unmet health need in the U.S. This is not because people don’t want it—but because they can’t afford it, can’t find it, or don’t realize how essential it really is.
The consequences of poor oral health care reach far beyond the mouth. Each year, untreated dental issues send over 2 million Americans to emergency rooms for pain that could have been prevented with regular dental care. And these visits don’t fix the root issue; they treat pain or infection at great cost to both patients and the healthcare system. Poor oral health is linked to serious medical conditions, including heart disease, diabetes, pneumonia, and even complications in pregnancy. Essentially, neglecting your mouth opens the door to illness everywhere else. Yet, dental care remains separate from the rest of the health care system, often treated like a luxury rather than a necessity.
The effects of dental neglect go beyond the physical. They’re deeply social and emotional. A healthy smile is more than just a cosmetic concern; it’s tied to confidence, employability, and how people are treated in daily life. Untreated tooth decay causes missed school and work, preventable pain, stigma in job interviews or public interactions, and reduces quality of life. This phenomenon shows how oral health gaps can reinforce existing social inequalities and shape life outcomes in subtle but powerful ways. And all of this circles back to access. The communities most affected by poor oral health—low-income families, rural populations, communities of color—are often the ones with the fewest affordable dental providers, longest waitlists, and least insurance coverage. It’s not a lack of motivation, it’s a lack of infrastructure. Without investment in community dental clinics, school-based programs, and expanded dental coverage, these disparities will only grow.
So why isn’t dentistry part of the broader conversation about health equity and access? The answer lies in a longstanding separation between dentistry and medicine. Despite how critical it is to our overall well-being, dental care has long been isolated from the rest of the healthcare system. Medical and dental education are separate. In the U.S., dental care is often excluded from health insurance coverage, and for adults, it’s not considered an “essential health benefit”. This division isn’t just bureaucratic; it has real consequences. As a result, millions are left without coverage or access to routine dental care. And since cost is the most significant factor keeping Americans from accessing dental care, this fragmented system disproportionately harms low-income communities. The result? Preventable dental issues worsen until they become emergencies, fueling a cycle of pain, illness, and inequality that goes largely unnoticed.
So what can be done? Bridging the gap between dentistry and broader health care requires both systemic reform and a shift in mindset. That includes integrating dentistry and medicine, expanding dental coverage under public insurance programs, and bringing dental education into conversations about prevention and community health. Oral health is one of the most preventable and treatable health issues worldwide, yet it remains one of the most neglected. If we truly care about health equity, we can’t leave teeth behind. It’s time we start treating oral health like what it is: essential. That means removing barriers to access, investing in prevention, and most importantly, treating dental care not as a privilege, but as a human right.
