Choosing health, dental and vision insurance comes down to eight factors. They are total yearly cost, annual limits, networks, covered services, waiting periods, kids' benefits, expected care and enrollment timing. Weigh them together, because a cheap plan in one area can cost you more in another. Then buy the plans as a set that fits your family.
- For 2027 coverage, ACA health plans cap in-network out-of-pocket costs at $12,000 for one person and $24,000 for a family.
- Dental and vision care for children are essential health benefits on HealthCare.gov, but adult dental and vision are not.
- You can't buy a Marketplace dental plan unless you buy a health plan at the same time.
- Many dental plans cap what they pay each year, and UnitedHealthcare lists maximums from $1,000 to $3,000.
- HealthCare.gov Open Enrollment for 2027 coverage runs Nov 1 to Jan 15, and you must enroll by Dec 15 for a Jan 1 start.
How health, dental and vision insurance differ
All three plans charge a premium and use a network. However, they protect you in very different ways. The biggest difference is who carries the risk when bills get large.
| Plan | Main job | Yearly limit |
|---|---|---|
| Health | Pays for doctor visits, hospital stays and prescriptions | An out-of-pocket maximum caps what you pay |
| Dental | Pays for cleanings, fillings and major repairs | An annual maximum caps what the plan pays |
| Vision | Pays for eye exams, glasses and contacts | Allowances cap what the plan pays for eyewear |
Health plans cap what you pay, while dental and vision plans cap what they pay.The difference our licensed agents explain most
In other words, your health plan is your safety net for big bills. Dental and vision plans, by contrast, help with routine care you can plan for. So when you shop for health, dental and vision insurance, judge each plan by its own job. To start with the medical side, compare ACA and private health plans.
Cost factors: premiums, deductibles and caps
Price is where most people start. Still, the monthly premium is only one part of what you'll spend in a year.
1. Total yearly cost of all three plans
Add up every premium for the year. Then add what you'd likely pay for care, such as deductibles and copays. That total is the real price of your health, dental and vision insurance.
For example, say Plan A costs $450 a month with a $7,000 deductible. Plan B costs $520 a month with a $3,000 deductible (sample figures). If you expect surgery this year, Plan B's lower deductible saves you $4,000 but costs $840 more in premiums. As a result, Plan B wins by about $3,160.
2. Annual limits on dental and vision plans
For 2027 coverage, ACA health plans cap in-network out-of-pocket costs at $12,000 for one person and $24,000 for a family. Dental plans work the other way. For instance, UnitedHealthcare says its dental plans cap yearly benefits at $1,000 to $3,000. Learn more about how an out-of-pocket maximum works.
Next, compare metal levels on the health side. Our guide to how bronze, silver and gold plans compare shows how each level splits costs with you.

Coverage factors: networks, benefits and waiting periods
Once you know the price, check what you actually get. These three factors decide whether the plan works when you need it.
3. Networks for doctors, dentists and eye doctors
Each plan has its own network, so your doctor may be in one and not another. Also, out-of-network care usually costs much more. So search every carrier's provider directory for your doctor, dentist and eye doctor before you buy.
4. What each plan covers
Health plans on the Marketplace must cover 10 essential health benefits, such as hospital care and prescriptions. Dental and vision plans, however, vary a lot. For example, some dental plans limit implants, while vision plans differ on lens upgrades. See what dental plans pay per service and what a vision plan pays for eyewear.
5. Waiting periods on dental and vision plans
A waiting period is the time before a plan pays for certain care. HealthCare.gov notes that separate dental plans can have waiting periods for adults. Therefore, if you need a crown soon, compare waiting periods first.
Starting major dental work during a waiting period can leave you with the whole bill. Ask for the exact waiting period in writing, then book your work after it ends.
Family factors for health, dental and vision insurance
Your household shapes the right mix more than any other factor. In particular, kids change the math, because the rules treat them differently from adults.
6. Your kids' dental and vision benefits
On HealthCare.gov, pediatric services, including dental and vision care, are essential health benefits. In fact, all Marketplace health plans include vision coverage for children. Dental for kids must be available, although you aren't required to buy it. Meanwhile, adult dental and vision are not essential health benefits.
- Offered by some Marketplace health plans
- Benefits may focus on kids
- Medical deductibles can apply
- Often stronger adult benefits
- Can have waiting periods
- Sold on and off the Marketplace
Check what your health plan already includes for the kids before you add more. Our guide to health plans that cover your kids explains the options.
7. The care you expect this year
Next, think about the year ahead. Then match each plan to the care you know is coming.
Put more of your budget into a health plan with a lower deductible.
Look for dental plans with short waits and a higher yearly cap.
A vision plan with strong allowances often pays for itself.
Consider a bronze or silver plan plus basic dental for cleanings.
Timing: when to buy each plan
The last factor is timing, and it trips up many buyers. Health plans and Marketplace dental plans follow Open Enrollment, while many private plans don't.
8. Enrollment windows and bundling
On HealthCare.gov, Open Enrollment for 2027 coverage runs from Nov 1 to Jan 15. Enroll by Dec 15 for coverage that starts Jan 1. Then, if you enroll from Dec 16 to Jan 15, coverage starts Feb 1. State exchanges can set different dates.
You can't buy a Marketplace dental plan on its own. Instead, you buy it with a health plan at the same time. By contrast, UnitedHealthcare says its private dental plans are available all year. So you can add dental and vision plans later if your needs change. See our Open Enrollment dates and checklist for every deadline.
A quick checklist before you enroll
Use these steps to pull all eight factors together. Most families can finish them in one phone call with an agent.
- List your doctors
Write down your doctor, dentist and eye doctor, plus any prescriptions.
- Estimate the year
Note planned care, such as surgery, crowns or new glasses.
- Price all three plans
Add premiums plus likely out-of-pocket costs for each plan.
- Check waits and limits
Compare waiting periods, annual maximums and allowances.
- Watch the deadline
Finally, enroll by Dec 15 for a Jan 1 start on HealthCare.gov.
Bring one list to the call: your doctors, your prescriptions and any dental or eye work you expect. With that list, we can check every network at once and price all three plans together. That way, nothing falls through the cracks.

Health, dental and vision insurance: FAQs
Should I buy health, dental and vision insurance together?
Not always. Buying all three at once makes it easy to compare networks and total cost. However, the best health plan and the best dental plan may come from different carriers. So compare each plan on its own job first. Then decide whether a bundle or separate plans gives you the better value.
Does health insurance include dental and vision?
For children, Marketplace health plans include vision coverage, and dental for kids must be available. For adults, though, dental and vision aren't essential health benefits, so most adults need separate plans. Some health plans do include adult dental or vision, so check the plan summary before you buy extra coverage.
Can I buy dental and vision plans any time?
It depends on where you buy. On the Marketplace, you can only buy a dental plan together with a health plan, usually during Open Enrollment. Meanwhile, UnitedHealthcare says its private dental plans are available all year. Our full set of dental answers covers more timing questions.
What matters most when comparing all three plans?
Start with your doctors and the care you expect. Next, compare total yearly cost, not just premiums. Then check annual limits, waiting periods and kids' benefits. In most cases, the network and the total cost decide the winner, while the other factors break ties.
Is a low premium always the better deal?
No. A low premium often comes with a higher deductible or smaller benefits. For example, a low-cost dental plan may have a long wait for crowns. So add up premiums and likely costs for the full year before you choose. That number shows the real price.
