Dental insurance for adults

Stand-alone dental plans are available through the exchange in every state, although the number of plan options varies from one area to another.

During the open enrollment period for 2025 coverage, nearly 2.9 million people enrolled in stand-alone dental plans through the exchanges nationwide.⁸ (For comparison, more than 24.3 million people enrolled in private health plans through the exchange.) And most of the people who enrolled in stand-alone dental plans through the exchanges were adults – only about 306,000 were under the age of 18.⁹

Most dental plans are managed care plans,¹⁰ although some are indemnity plans.

• Indemnity plans (also known as fee-for-service plans) do not have provider networks and will allow you to see any dentist you like. But the plan will only pay a set amount for each service, and you’re responsible for the rest of the dentist’s bill. These plans are much less common than they used to be, and account for just a small fraction of current dental plans.¹¹
• A managed care dental plan can be a PPO (preferred provider organization), HMO (health maintenance organization), EPO (exclusive provider organization), or POS (point of service) plan. Here’s an overview of how those types of managed care work in terms of health insurance. The general ideas are similar for dental plans. All four types of managed care dental coverage will have a network of dentists you can utilize. Staying within that network will keep your costs as low as possible (and dental HMOs and EPOs generally won’t cover any out-of-network care). Some plans, particularly HMOs, will require you to have a primary care dentist who will need to write a referral in order for specialty dental care to be covered.
• Dental PPOs are the most common type of plan, accounting for the majority of the dental plan market share.¹²

Stand-alone adult dental coverage generally has a benefit cap of between $1,000 and $2,000.¹³ For most routine dental work, this will generally be plenty, and most enrollees do not hit their dental benefit cap.¹⁰ But if you end up needing extensive dental work – such as multiple implants – you may find that your needs exceed the benefit cap.

On any adult dental plan, preventive services (cleanings, exams, x-rays) will typically be fully covered. For basic services, such as fillings, extractions, and root canals, it’s common to see 70% or 80% coverage. And the cost of more substantial services, such as crowns, bridges, and implants, is often split 50/50 between the dental plan and the patient, up to the plan’s benefit caps.¹⁰

Some adult dental plans will increase your benefit cap over time, or reduce your deductible or coinsurance rate over time. For example, you might get a plan that initially has a $1,000 benefit cap, but it grows to $1,250 in the second year and $1,500 in the third year. Or you might find a plan that requires you to pay 50% of the cost of certain services in the first year, 40% in the second year, and only 20% in future years, or a plan that reduces or eliminates the deductible over time.

If you’re planning to continue to have dental insurance over the long run and you’re happy with the dental network that the plan offers, this type of plan could reward your loyalty with enhanced benefits over time.

Most adult dental plans will cover routine preventive care (exams, cleanings, x-rays)  as soon as your plan takes effect. But it’s common for adult dental plans to have waiting periods of up to a year before some of the more expensive dental procedures are covered. (A typical waiting period structure is six months for basic services and 12 months for major services.) However, the insurer may waive the waiting period if you show proof that you had other dental coverage prior to enrolling in the new plan.¹⁴

If you’re shopping outside the exchange and you have children in your family who will be on the dental plan with you, keep in mind that the ACA’s pediatric dental benefits do not have to be offered on plans that you purchase outside the exchange.¹⁵

If you’re only buying coverage for adults, the overall benefit options will be fairly comparable on-exchange and off-exchange, since there are not specific regulations that on-exchange adult dental plans must follow. But if your plan will also cover children, the benefits that will be provided to the children via an on-exchange dental plan could be much more robust than the benefits that will be provided to adults. This will generally be true even if the children and adults are covered under the same plan; the benefit specifics will be different due to the face that pediatric dental is an essential health benefit while adult dental is not.

As noted above, in most states, dental insurance can only be purchased through the exchange during open enrollment or a special enrollment period. And in more than half of the states, it can only be purchased together with health insurance – which means the exchange might not be a good solution if you only need dental insurance.

For example, maybe you work for an employer that provides medical coverage but not dental coverage. Or maybe you have Medicare and thus cannot buy an individual-market plan. (Original Medicare does not cover dental services, but Medicare beneficiaries do not need – and cannot buy – health coverage in the Marketplace.)

Fortunately, there are off-exchange dental plans available nationwide, year-round, without the need for a qualifying event. Depending on where you live, you’ll generally find that different insurers offer plans on-exchange and off-exchange, so it’s worth comparing both options (assuming you’re eligible to purchase a dental plan through the exchange).

As an example, let’s look at the stand-alone dental plans that are available through the exchange (Georgia Access) in the Atlanta area. There are 26 dental plans available for 2026, offered by nine different dental insurers. Most are dental PPOs, but there is one dental EPO.¹⁶

• On the inexpensive end of the spectrum, the premiums for a single adult are less than $10/month – but some of those plans only cover basic preventive care (exams, x-rays, and cleanings).

The most expensive plans have premiums as high as about $46/month for a single adult. But these plans still have benefit caps of $1,000 or $1,500 and waiting periods of up to 12 months for major services. Depending on the plan and whether the member uses an in-network dentist, it’s common to see 70% to 90% coverage for basic services and 50% coverage for major services.

Dental premiums matter …

The monthly premium for a self-purchased dental plan for a single adult could range from under $10 to more than $50.. If a plan has a very low premium, be aware that it might be a dental discount plan, might only cover preventive care, or might have a very limited provider network. As always, you’ll want to read all of the fine print.

On the higher end of the price spectrum, you might have more robust benefit limits, shorter waiting periods, a larger network of dentists, or lower costs when you receive dental services (for example, the plan might have a lower deductible, or pay a larger percentage of the cost of various services).

But don’t assume that you need to buy the most expensive plan in order to have the best benefits. There are price differences from one insurer to another that aren’t related to the quality of the plan. And if you’re happy with the dentists you can use on a plan with a smaller network, you may find that you can save money by choosing that plan, as opposed to a plan with a broader network.

Dental insurance premiums tend to be similar for employer-sponsored coverage, but many employers, particularly large employers, pay a portion of the premiums.² When people are purchasing their own adult dental coverage, they have to pay all of the premiums themselves.

… but consider your dental care utilization.

So it’s important to run the numbers, consider your normal dental care utilization, and figure out whether it makes sense to buy a stand-alone dental plan, sign up for a dental membership with your preferred dentist, enroll in a dental discount plan, or just pay full price each time you need dental care.

But dental insurance usually makes financial sense for individuals needing somewhat extensive dental work. The average cost of a root canal can be well over $2,000 once you account for the price of the root canal and the new crown.¹⁷ For services like that, a person with a dental plan will likely come out ahead, assuming that they’ve completed any necessary waiting periods before the need for care arises.

But again, the benefit caps mean that most adult dental benefits will be fairly limited in terms of the coverage they’ll provide if a person needs extensive dental work. Multiple dental implants, for example, would not be covered in a single year due to the benefit cap on most adult dental policies.

When you’re shopping for dental coverage, there are several points you’ll want to understand about each plan, so that you can compare them:

• What’s the annual benefit cap?
• What services have waiting periods, how long are the waiting periods, and can the waiting period be waived if I’ve had continuous coverage under another plan?
• What dentists are in-network, and how much coverage will I have if I go outside the network?
• Will I have to pay anything for routine preventive care, including cleanings and X-rays?
• How much will I pay for basic and major services?
• What services are excluded? Examples might be orthodontia or implants, but you’ll want to be sure you understand the specific exclusions of any plans you’re considering.
