Most people find out the hard way: they book an eye exam or a dental cleaning, hand over their Medicare card, and get a bill for the whole visit. Original Medicare treats vision, dental, and hearing care as three separate categories it mostly doesn't touch, and none of the three get a courtesy warning before the appointment.
That gap is easier to plan around once you know exactly where it sits. This walks through what Part A and Part B actually skip, what a real year of care in each category tends to cost, and where a Medicare Advantage plan can genuinely help versus where it just sounds like it does.

What Original Medicare Actually Skips
Part B covers a narrow set of vision exceptions: glaucoma screenings for people at high risk, diabetic retinopathy exams once a year, and cataract surgery plus one pair of glasses or contacts afterward. A routine eye exam for a new glasses prescription, outside of those cases, is not covered.
Dental works the same way. Routine cleanings, fillings, extractions, dentures, and periodontal treatment are not covered by Original Medicare, with a narrow exception for dental work tied directly to a covered medical procedure, like clearing an infection before heart surgery. Hearing follows the same pattern: Part B may cover a diagnostic hearing exam your doctor orders for a medical reason, but routine hearing exams and hearing aids themselves are not covered.

Put a Number on It Before You Book
A single set of glasses or contacts can run a few hundred dollars once the exam is included. A dental cleaning and checkup is often in a similar range, and real work like a filling or a crown costs more on top of that. Hearing aids are the biggest gap of the three: a pair typically costs well into four figures, which is exactly why so many people put the appointment off.
None of that has to be a guess. Put your own numbers in below so you have a real figure to compare against any plan benefit before you decide what to do next.

When a Medicare Advantage Plan Fills the Gap, and When It Doesn't
Some Medicare Advantage plans add vision, dental, or hearing benefits that Original Medicare doesn't offer, and that can be real savings. The catch is that those benefits usually come with an annual dollar cap, a limited network of providers, and a line between preventive coverage and bigger work like dentures or a full set of hearing aids.
A plan that advertises "dental coverage included" might mean one free cleaning a year and nothing toward a crown. Read the actual benefit summary, not the headline, before you count on it.

Common questions
Does Medicare cover eye exams and glasses?
Original Medicare covers a narrow set of vision exceptions: glaucoma screenings for people at high risk, an annual diabetic retinopathy exam, and cataract surgery plus one pair of glasses or contacts afterward. A routine eye exam for a new glasses prescription outside of those cases is not covered.
Does Medicare cover dental work?
Routine dental care, including cleanings, fillings, extractions, dentures, and periodontal treatment, is not covered by Original Medicare. The narrow exception is dental work required to safely complete a covered medical procedure, such as clearing an infection before heart surgery.
Will a Medicare Advantage plan cover my hearing aids?
Some Medicare Advantage plans add a hearing benefit, but it usually comes with an annual dollar cap and a limited network of providers. Check the plan's actual benefit summary for the dollar limit and which providers are in-network before you assume it covers a full pair of hearing aids.
How much should I budget for vision, dental, and hearing care in a year?
It depends on what you need, but a single pair of glasses or contacts with an exam often runs a few hundred dollars, a dental cleaning and checkup is in a similar range with real work like a filling costing more, and hearing aids are typically the largest cost, often well into four figures for a pair. Put your own numbers into a simple estimate so you have a real figure to compare against any plan benefit.
