Teeth Tell the Story

When Sandra smiles, she covers her mouth with her hand.

She is 68 years old. She has four teeth remaining in her upper jaw. The rest were extracted over the past fifteen years, one by one, as problems arose that she could not afford to fix. A cavity that would have cost $200 to fill became an abscess that cost $150 to extract. Multiply that by ten, and you have Sandra’s mouth.

She cannot chew meat anymore. Raw vegetables are difficult. She has learned to cut food into small pieces and swallow without much chewing, or to stick with soft foods: mashed potatoes, canned soup, white bread. Her doctor has told her that her nutrition is suffering, that she needs more protein, more fiber. She knows. She cannot eat it.

Sandra stopped going to church two years ago. The coffee hour after services, the potlucks, the gatherings: she could not eat what others were eating, and she could not explain why without opening her mouth. So she stopped going. She stopped going to most places where people might see her smile.

She is not poor enough for Medicaid. She is not rich enough for implants. She is in the gap that Medicare created and has never closed.

The Coverage Gap

#

When Medicare was enacted in 1965, dental care was explicitly excluded from coverage. The exclusion was a political compromise, a way to reduce the program’s cost and placate the dental profession, which opposed government involvement in its market. Sixty years later, the exclusion remains.

Approximately 70 percent of Medicare beneficiaries have no dental coverage at all. Among those with coverage, most have it through Medicare Advantage plans that include limited dental benefits, or through standalone dental insurance they purchase separately. The coverage skews heavily by income: roughly 85 percent of high-income seniors have dental coverage; roughly 25 percent of low-income seniors do. Access follows coverage. Care follows access. Teeth follow care.

Medicaid coverage for adult dental varies enormously by state. Some states provide comprehensive dental benefits. Others cover only emergency extractions, which means they will pull a rotting tooth but will not fill a cavity before it rots. A handful of states cover nothing at all. The patchwork means that a low-income senior’s dental fate depends on which side of a state line she lives on.

Private dental insurance is available to those who can pay. Annual premiums run $300 to $600 or more for individual coverage. But private dental insurance is not like health insurance. Annual maximum benefits typically cap at $1,000 to $2,000, a limit that has barely increased since the 1980s even as dental costs have risen steadily. A single crown can exhaust a year’s benefit. Major restorative work exceeds what insurance will pay, often by tens of thousands of dollars.

The result is a two-tier system. Those with resources maintain their teeth. Those without lose them.

The Cost of Care

#

The arithmetic of dental care creates a predictable pattern. Routine care is manageable for many: a cleaning runs $100 to $200, a filling $150 to $300. These are not trivial sums for someone living on Social Security, but they are within reach for those who prioritize dental visits.

Major care is another matter. A root canal costs $1,000 or more. A crown costs $1,000 to $1,500. An extraction costs $200 to $500. An implant to replace a lost tooth costs $3,000 to $5,000. Full dentures run $1,000 to $3,000 for basic models, more for better quality.

For Sandra, the calculation was never really a calculation. When her first molar started to ache, she did not have $1,500 for a root canal and crown. She had $150 for an extraction. When the next tooth went bad, the math was the same. Each extraction made the next one more likely, as remaining teeth shifted and bore more pressure. The mouth does not stabilize after tooth loss. It deteriorates.

Full mouth restoration, the dental work that could give Sandra back the ability to eat normally, would cost $25,000 to $50,000 or more. This is care available to the wealthy. For Sandra, it might as well be a million dollars.

What Happens Without Care

#

The consequences of untreated dental disease cascade through the body.

Tooth loss is the most visible outcome. Approximately 26 percent of American adults aged 65 and older have lost all their natural teeth. Among the poor, the percentage is significantly higher. Among Black and Hispanic seniors, higher still. The mouth becomes a record of disadvantage, written in absence.

Infection is the dangerous outcome. An untreated cavity progresses to pulp infection, then to abscess, then potentially to systemic infection. Dental infections send roughly 2 million Americans to emergency rooms each year, at costs far exceeding what preventive care would have required. In rare but documented cases, untreated dental infections kill. They spread to the brain, the heart, the bloodstream. People die from toothaches in the wealthiest country in the world.

Malnutrition follows tooth loss. Without adequate teeth, chewing becomes painful or impossible. People shift to soft, processed foods: less fresh produce, less lean protein, more refined carbohydrates. Nutrient intake declines. For seniors already managing diabetes, heart disease, or kidney problems, the dietary limitations compound existing conditions.

The systemic connections run deeper than nutrition. Periodontal disease (chronic gum infection) is associated with elevated cardiovascular risk, worse diabetes control, and emerging evidence suggests links to cognitive decline. The mouth is not separate from the body. Inflammation in the gums affects inflammation elsewhere. Bacteria in infected teeth can enter the bloodstream. Dental health is health.

Mental health suffers in ways that research has documented and anyone can observe. Tooth loss is associated with higher rates of depression, anxiety, and social withdrawal. People with missing or damaged teeth smile less. They speak less. They leave their homes less. They are seen differently by others and by themselves. The shame of dental disease, even when it results from structural exclusion rather than personal failure, shapes daily life.

Sandra does not feel like herself anymore. She remembers being confident, outgoing, someone who laughed easily. Now she calculates every social interaction against the risk of being seen. The extraction of her teeth extracted something else too.

The Visible Marker

#

Most health conditions are invisible. You cannot look at someone and know they have high blood pressure, early-stage diabetes, or elevated cholesterol. But you can see their teeth.

Dental status functions as a class marker in ways that are immediate and visceral. Research confirms what most people intuitively know: missing or damaged teeth trigger negative judgments about intelligence, competence, trustworthiness, and social status. In employment interviews, in social settings, in romantic contexts, teeth matter. They signal something about resources, about access, about where someone stands.

This visibility makes dental health different from other health disparities. The hidden suffering of poverty, the diseases that accumulate without being seen, can remain private. Teeth cannot. Every smile, every word, every meal in public exposes what the mouth contains or lacks. There is no hiding.

The shame that follows is common and corrosive. People apologize for their teeth. They explain, unprompted, that they know their mouth is bad. They have internalized a judgment that originates in policy failure and landed on their bodies. Sandra knows that her missing teeth are not her fault, that she worked hard and did her best and simply could not afford what the dental system charged. She knows this. She still feels ashamed when she opens her mouth.

The Policy Choice

#

The exclusion of dental care from Medicare is not a law of nature. It is a decision, made in 1965, revisited and reaffirmed by inaction in every decade since. Bills to add comprehensive dental benefits to Medicare have been introduced repeatedly in Congress. None have passed.

The Congressional Budget Office estimates that adding dental coverage to Medicare would cost approximately $200 to $400 billion over ten years, depending on program design. Critics cite this cost as prohibitive. Advocates note that it represents a fraction of Medicare’s total spending and that the downstream costs of untreated dental disease (emergency room visits, worsened chronic conditions, reduced quality of life) are also substantial, just distributed differently and counted in different budgets.

The deeper obstacle is conceptual. Dental care has historically been framed as separate from medical care, as somehow less essential, as cosmetic rather than functional. This framing is medically false. The mouth is part of the body. Oral infections are infections. Tooth loss affects nutrition, speech, and systemic health. But the false distinction between dental and medical has political power. It allows policymakers to exclude dental without appearing to deny healthcare.

Other countries have made different choices. Most developed nations include some level of dental coverage in their public health systems or provide substantial subsidies for dental care. The United States stands out for the explicitness of its exclusion and the predictability of its consequences.

What Would Change

#

Adding a comprehensive dental benefit to Medicare would close the coverage gap. Not just emergency extractions, but preventive care, restorative care, and prosthetics. The political difficulty of this change is real, but so are the political changes that seemed impossible until they happened.

Expanding Medicaid dental coverage through federal standards would eliminate the state-by-state lottery that currently determines whether a low-income senior can get a filling. Requiring states to provide comprehensive adult dental as a condition of Medicaid participation would create a floor that currently does not exist.

Expanding community health center capacity would increase access to affordable dental care. Federally qualified health centers provide dental services on a sliding-fee scale, but many have waiting lists measured in months. Investing in dental capacity at these centers would reduce the gap between need and access.

Expanding the dental workforce through dental therapy would bring more providers into underserved communities. Dental therapists are mid-level providers, similar to physician assistants in medicine, who can perform routine procedures at lower cost. They face opposition from organized dentistry, which protects its market, but where implemented they have increased access without compromising quality.

None of these changes will happen automatically. All require political pressure, sustained attention, and the decision that dental care is healthcare and should be treated accordingly.

The Mouth as History

#

Open your mouth. Your economic history is visible there.

The teeth you have, or do not have, reflect decades of access or exclusion. The fillings you could afford. The root canals you could not. The extractions that substituted for repair. The preventive care that happened or didn’t. The compound effect of class, expressed in enamel and absence.

Sandra did nothing wrong. She worked, she raised children, she managed what she had. She did not neglect her teeth. She could not afford them. And now, at 68, she covers her mouth when she smiles, eats alone, and does not go to church.

The exclusion of dental care from Medicare was a political choice. The suffering that follows is the predictable consequence of that choice. Different choices are possible. They have not been made. Until they are, teeth will continue to tell the story of class in America, one missing molar at a time.
