Why Dental Isn’t Covered by Health Insurance Plans (And Why That Matters)

When most people sign up for health insurance, they’re surprised, and often frustrated, to learn that dental coverage isn’t included. Despite the well-established connection between oral health and overall wellness, medical and dental insurance remain separate in the U.S. health system.

So why is that the case?

The answer lies in a combination of historical decisions, industry structures, and how health policy has evolved over time.

A Historical Divide

The separation of dental and medical insurance dates back to the 1940s and 1950s, when employer-sponsored health insurance began to take root in the U.S. As health benefits were increasingly offered to workers as a recruitment and retention tool, medical insurance became the norm, but dental benefits were still viewed as non-essential or even “cosmetic.”

By the 1950s, organized dentistry began advocating for a standalone dental benefits model, largely to maintain autonomy from the emerging health insurance sector. The American Dental Association (ADA) supported keeping dental care separate from broader healthcare policy. As a result, dental benefits evolved independently, typically as optional add-ons or separate policies.

This division was solidified further in 1965, when Medicare was created and explicitly excluded routine dental services from coverage. That exclusion remains to this day, with only limited dental coverage offered under Medicare Part A, and only when dental services are provided as part of a covered hospital stay.

What This Means Today

Today, more than 68 million Americans have no dental insurance at all, according to the National Association of Dental Plans (NADP). That’s more than twice the number of people without health insurance.

Even for those who do have dental coverage, it often comes with low annual maximums, typically between $1,000 to $2,000 per year, and limited coverage for major services like crowns or root canals. That’s a far cry from what most health plans offer in terms of catastrophic or long-term care coverage.

The Consequences of Poor Dental Access

This separation can lead to significant health consequences. According to the CDC, over 40% of adults in the U.S. have untreated dental issues. Research also shows links between poor oral health and chronic conditions like diabetes, heart disease, and stroke. Yet, without integrated dental and medical coverage, many people delay or avoid routine cleanings and exams altogether.

Will This Ever Change?

There have been ongoing policy discussions about integrating dental into medical insurance—especially for Medicare beneficiaries. Some states have expanded Medicaid dental benefits, and private insurers have started bundling plans. But for now, the divide remains.

Dental care is healthcare. However, because of historical choices and industry divides, it continues to be treated differently in both policy and practice. Understanding this divide is key to making informed decisions about your coverage.
