Original Medicare, the federal coverage that anchors retirement for tens of millions of Americans, pays nothing toward routine dental care, eye exams for glasses, or hearing aids. That reality lands hard in the first months of enrollment, because those are precisely the expenses that climb with age. A single pair of hearing aids often runs into the thousands of dollars, and a crown or a set of dentures is rarely far behind. The gap is not an oversight or a temporary lapse; it is built into how Parts A and B were designed, and no supplemental step erases it automatically.
Where Parts A and B stop: dental, vision, and hearing
Part A covers inpatient hospital stays and Part B covers doctor visits and outpatient care, yet neither touches the everyday upkeep of teeth, eyes, and ears. Medicare does not cover most dental care, a category that includes cleanings, fillings, extractions, dentures, and implants. Routine eye exams performed to prescribe glasses sit outside coverage as well, along with the eyeglasses and contact lenses themselves in nearly every situation. Hearing aids and the exams to fit them are excluded outright, which catches many people off guard given how common age-related hearing loss becomes after 65.
Narrow exceptions exist, and they cause confusion because they sound broader than they are. Part B pays for cataract surgery and one pair of corrective lenses afterward, and it covers dental work only when the procedure is an inseparable part of a larger covered treatment, such as jaw reconstruction following an accident or an extraction required before radiation. A diagnostic hearing or balance exam a doctor orders to investigate a medical symptom can be covered, while the identical visit aimed at fitting a hearing aid is not. The program spells out these exclusions in plain terms, and the dividing line is always medical treatment versus routine maintenance.
The vision exclusions are not absolute, and the narrow slivers that are covered reveal the underlying logic. Part B pays for an annual glaucoma screening for people at high risk, including those with diabetes or a family history of the disease, and it covers a yearly eye exam for diabetic retinopathy for enrollees who have diabetes. It also helps pay for diagnostic tests and treatment of eye diseases such as age-related macular degeneration when a doctor considers the care medically necessary. Each of these is a screen or treatment for disease rather than a refraction to update a glasses prescription, which is why they qualify while an ordinary vision exam does not.

The out-of-pocket math on teeth, eyes, and ears
Because Original Medicare contributes nothing, the full retail price of this care falls on the household. A crown, a bridge, or a root canal each reaches well into four figures, and a full set of dentures can approach the cost of a used car. Hearing aids compound the problem, since they typically cost several thousand dollars per pair and manufacturers rarely bundle the fitting, adjustments, and follow-up appointments into the sticker price. These are recurring costs, not one-time shocks, because devices wear out, prescriptions change, and dental work rarely stays finished.
The timing makes the exposure worse. Dental and hearing needs tend to intensify in the same years that fixed retirement income leaves the least room to absorb a surprise bill. A retiree who budgets carefully around premiums and prescription copays can still be blindsided by a single dental emergency, because that bill arrives with no Medicare cushion behind it. For a couple, the exposure doubles, and both members often reach the point of needing dentures or hearing aids within a few years of each other.
The plans that fill the gap, and their tradeoffs
Medicare Advantage plans, the private alternative to Original Medicare, frequently advertise dental, vision, and hearing benefits as extras that Original Medicare omits. The catch sits in the fine print: many of those dental benefits carry an annual cap, often in the range of a thousand to a couple thousand dollars, which a single major procedure can exhaust in one visit. Vision and hearing allowances tend to be modest as well, and the plans route care through networks, so a longtime dentist or audiologist may fall outside coverage. The benefit is real, but it is bounded.
The other common assumption is that a Medigap supplement closes the gap, and it does not. Medigap policies generally do not cover dental, vision, or hearing aids; their job is to defray the deductibles and coinsurance of Original Medicare, not to add new categories of care. That leaves standalone dental and vision plans as the main route for people who keep Original Medicare, and those premiums buy coverage that still comes with waiting periods and annual maximums of their own.
The result is a decision most retirees make without realizing it. Choosing Original Medicare with a Medigap plan buys broad, network-free medical coverage but leaves teeth, eyes, and ears self-funded, while choosing Medicare Advantage adds capped extras at the cost of network restrictions. Neither path makes routine dental, vision, and hearing care disappear as an expense; it only moves who pays and how much. The unresolved question for each household is whether the predictable annual cost of a supplemental plan beats the risk of paying full price in a bad year, and that answer looks different depending on the state of one’s teeth and hearing at the moment of enrollment.
