The coverage gap in Original Medicare that surprises people most is not the 20% coinsurance or the lack of an out-of-pocket cap. It is the complete absence of routine dental, vision, and hearing coverage. Medicare has not covered these services since its inception, and for the average retiree, the cost of dental work alone can run into the thousands of dollars. Medicare Advantage plans have used these gaps as a selling point, bundling dental, vision, and hearing benefits into many plans. Here is what the coverage actually looks like in practice.
The dental coverage story is one I have to manage expectations on constantly. "Dental included" on a brochure could mean anything from twice-yearly cleanings to a $2,500 annual maximum covering major work. I pull the Evidence of Coverage and look at the actual dental schedule before I let any client pick a plan for its dental benefit. The headlines are marketing; the fine print is the product.
Why Original Medicare does not cover these
When Medicare was created in 1965, routine dental care, eye exams, and hearing aids were considered separate from medical care. That categorization has never changed at the federal level, leaving significant gaps that affect nearly every Medicare enrollee as they age. Original Medicare does cover dental care only when it is medically necessary and directly related to a covered procedure, such as tooth extraction before cardiac surgery, but routine cleanings, fillings, and dentures are excluded entirely.
Dental coverage in Medicare Advantage plans
Dental benefits in Advantage plans range from basic preventive coverage to comprehensive care depending on the plan. Basic coverage typically includes routine cleanings, x-rays, and oral exams, usually up to two cleanings per year. Comprehensive dental coverage adds fillings, extractions, root canals, crowns, bridges, and sometimes dentures or implants. Most plans that offer comprehensive coverage set an annual maximum benefit between $1,000 and $2,500. After that maximum, you pay full price. Some plans impose waiting periods before they cover major services, particularly for enrollees in their first year.
What to actually look for in dental coverage
The devil is in the details. Before choosing a plan for its dental benefit, check whether your current dentist is in-network, whether the annual maximum covers your anticipated needs (a single crown often costs $1,000 to $1,500), whether there is a deductible before comprehensive coverage starts, whether there are waiting periods for major services, and what the plan covers under major versus basic categories. Two plans that both say dental included can differ dramatically in what that actually means.
Vision benefits
Most Advantage plans that include vision coverage provide an annual comprehensive eye exam and an allowance for glasses or contact lenses, typically between $100 and $300 per year. The allowance applies to frames, lenses, or contacts at in-network providers. Some plans extend coverage to include contact lens fittings or additional allowances for progressive lenses. Vision networks often include major optical chains like LensCrafters or Costco Optical as in-network providers.

Hearing aids are not covered by Original Medicare, and they are expensive, averaging $2,000 to $5,000 per device, with most people needing two. Advantage plans that include hearing coverage typically provide an annual hearing exam and an allowance toward hearing aids ranging from $500 to $2,500 per aid through contracted hearing aid providers. Some plans partner with national hearing networks. The annual allowance rarely covers the full cost of premium hearing aids, but it meaningfully reduces out-of-pocket expense.
How to compare quality, not just access
The phrase dental, vision, and hearing included tells you almost nothing useful. When comparing plans, look at the specific annual maximums, in-network provider lists, deductibles, waiting periods, covered services by category, and whether allowances roll over or expire at year end. A plan with a $2,500 dental maximum and comprehensive coverage is fundamentally different from one with a $500 maximum covering cleanings only, even if both advertise dental coverage.
