What Is Dental Insurance?

Dental insurance is insurance that covers dental health and care. Because dental health, also called oral health, is important to your overall health, you may want to get dental insurance to help you pay for the cost of your dental care. You can purchase dental insurance as part of a medical insurance health plan or as a separate policy through a dental insurer, the Health Insurance Marketplace , or a private insurance broker.

Dental Insurance vs. Dental Benefits

When shopping for insurance, you may see the term "dental benefits," which is different from dental insurance.

An insurance plan is meant to absorb risk (for instance, the risk that you’ll need to have a tooth pulled, or to get a ( root canal ) and it covers costs accordingly.

A benefits plan covers some things in full, but other things only partially, and others not at all. It’s meant to be helpful, but it’s not a catch-all.

If you have dental benefits, do you know what’s in the fine print and what type of plan is best for you?

Many Americans (79%) have dental benefits, the National Association of Dental Plans (NADP) says. Most people have private coverage, usually from an employer or group program. Large employers are more likely to offer dental benefits than small employers, and high-wage workers are more likely to receive them than low-wage workers. Medicare doesn’t cover dental care, and most state Medicaid programs cover dental care only for children.

To make the most of your benefits, you need to know these things. When you shop for dental coverage, make sure you understand what type of plan you are choosing, and what it covers.

Dental Insurance Categories

Although the features of plans may differ, the most common dental insurance offerings can be grouped into the following categories:

Direct reimbursement programs

Direct reimbursement programs pay you a predetermined percentage of the total amount you spend on dental care, regardless of the treatment category. This method typically doesn't exclude coverage based on the type of treatment needed and allows you to go to the dentist of your choice. And it encourages you to work with your dentist toward healthy and economically sound solutions.

"Usual, customary, and reasonable" (UCR) programs

UCR programs usually allow you to go to the dentist of your choice. These plans pay a set percentage of the dentist's fee or the plan administrator's "reasonable" or "customary" fee limit, whichever is less. These limits are the result of a contract between the plan purchaser and the third-party payer. Although these limits are called "customary," they may or may not accurately reflect the fees that local dentists charge. There is a wide fluctuation and lack of government regulation on how a plan determines its "customary" fee level.

Table or schedule of allowance programs

These programs provide a list of covered services with an assigned dollar amount. That amount represents just how much the plan will pay for services that are covered, regardless of the fee charged by the dentist. The difference between the allowed charge and the dentist's fee is billed to you. This is called balance billing.

Capitation programs

Capitation programs pay contracted dentists a fixed amount (usually every month) for each enrolled family or patient. In return, these dentists agree to provide specific types of treatment to you at no charge. (For some treatments, you may need to make a co-payment.) The capitation premium that is paid may differ greatly from the amount the plan provides for the patient's actual dental care.

Dental Insurance Plans

Dental insurance plans are similar in some ways to health insurance plans, but different in other ways. You’ll generally have the following options:

Preferred provider organization (PPO)

As with a health insurance PPO, these plans come with a list of dentists and other oral health care providers that accept the plan. These are referred to as in-network providers. Going to an in-network provider offers you the lowest out-of-pocket cost. You may have the option of going out of network, but your out-of-pocket costs will be higher than the costs incurred using an in-network provider.

Dental health maintenance organization (DHMO)

Like a health insurance HMO, DHMO plans provide a network of dentists that accept the plan for a set co-pay, or no fee at all. However, you may not be able to see an out-of-network dentist. If you do, you may have to pay the full amount on your own.

Discount or referral dental plan

A discount or referral dental plan offers you a discount on dental services from a select group of dentists. Unlike health insurance, this type of plan doesn’t pay anything for your care. Rather, the dentists who participate agree to give you a discount for the care you receive. These plans are also called access plans or savings plans.

Private dental insurance

Private dental insurance is insurance you purchase on your own, and not through an employer. You can purchase private dental insurance directly through a dental insurer, HealthCare.gov, or an insurance broker.

Dental Insurance for Seniors and Low-Income Residents

Once you reach age 65, or if you meet certain low-income and resource requirements, you may qualify for government-funded health insurance plans. Here’s how those plans handle dental coverage:

Medicare

Medicare is health insurance for people aged 65 and older. You may also be eligible for Medicare if you have a disability, amyotrophic lateral sclerosis, or end-stage renal disease. Medicare is funded by payroll taxes paid by most employees, employers, and people who are self-employed as well as by funds authorized by Congress. Most people don’t pay any monthly premium for Medicare Part A, or hospital insurance benefits. For Medicare Part B, or medical insurance benefits, you will pay a standard monthly premium.

Medicare usually doesn't cover dental services such as routine cleanings, fillings, or tooth extractions. It also doesn’t cover items such as dentures. You pay 100% of non-covered dental services. Medicare may cover certain dental procedures that require you to be admitted to a hospital as an inpatient, either due to the severity of the dental procedure or because you have an underlying medical condition. Medicare may also cover specific inpatient and outpatient dental services related to covered medical conditions or the success of medical treatments. You will still be responsible for paying the Medicare Part-A deductible and co-pays for your hospital stay. For Part B-covered dental services, you pay 20% of the Medicare-approved amount after you meet the Part B deductible. You’ll also pay a facility co-payment for covered dental services you receive in a dentist’s office or another outpatient setting.

Medicare Advantage Plans (Part C)

Medicare Advantage Plans provide all your Medicare Part A and B benefits and other benefits not covered under Medicare. Depending on the plan you choose, it may cover dental services, such as routine checkups or cleanings. Your monthly premiums, deductibles, coinsurance, and co-payments vary based on which plan you join. Once you pay the plan’s yearly out-of-pocket limit, it pays 100% for covered health services for the rest of the year.

Medicare supplement insurance

Also called Medigap, Medicare supplement insurance is extra insurance that helps you pay your out-of-pocket costs associated with Original Medicare. You can buy a Medigap policy from a private insurance company. Because all Medigap policies are standardized, they offer the same basic benefits no matter where you live or from which insurance company you buy the policy. Price is the only difference between the 10 different types of plans offered by most states. Medigap policies generally don’t cover dental care.

Medicaid

Some people with limited income and resources may qualify for Medicaid, a joint federal and state program that helps cover medical costs generally not covered by Medicare. Each state sets its own rules to determine who is eligible for Medicaid. Under Medicaid’s Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit, states are required to cover dental services for people enrolled under the age of 21. Most states provide emergency dental services for adults in their Medicaid programs, but less than half of the states provide comprehensive dental care.

Other Medicare health plans

There are three other Medicare health plans that can help you lower costs. Each has its own eligibility and requirements.

Understanding Dental Insurance Plans

In-network and out-of-network dentists

You'll be given a list of dentists who participate in your dental insurance plan. These are known as in-network providers. Most dental insurance plans will only pay for care if you go to a contracted and participating in-network dentist, orthodontist, or other oral health care specialist. Going to an in-network provider often results in the lowest out-of-pocket costs for you.

Most PPOs allow you to see dentists who don't participate in your plan. These are known as out-of-network providers. Even though a PPO allows you to see out-of-network providers, the plan will pay a much lower percentage of the cost than it does for seeing an in-network provider. Your out-of-pocket costs will be higher when seeing out-of-network providers.

When it comes to HMOs, these plans usually don't allow you to see out-of-network providers. They won't pay for any dental care that isn't provided by an in-network provider. When you have an HMO dental plan and see an out-of-network provider, the entire cost of dental care you receive falls on you.

Medicare and Medicaid plans also have a list of dentists and other oral health providers who accept these plans. You can look up and compare providers in your area at Medicare.gov.

Predetermination of costs

Some dental insurance plans encourage you or your dentist to submit a treatment proposal to the plan administrator before receiving any care or treatment. The administrator may determine your eligibility, the eligibility period, services covered, your co-payment, and the maximum limitation. This is called predetermination. Some plans require predetermination for treatment over a specified dollar amount. This is also known as preauthorization, precertification, pretreatment review, or prior authorization.

Annual benefits limitations

To help contain costs, your dental insurance plan may limit benefits by the number of procedures or dollar amount in a given year. In most cases, especially if you've been getting regular preventive care, these limitations allow for adequate coverage. By knowing what and how much the plan allows, you and your dentist can plan treatment that will minimize out-of-pocket expenses while maximizing compensation offered by your benefits plan.

Peer review for dispute resolution

Many dental insurance plans have a peer review mechanism through which disputes among third parties, patients, and dentists can be resolved, eliminating many costly court cases. Peer review aims to ensure fairness, individual case consideration, and a thorough examination of records, treatment procedures, and results. Most disputes can be resolved satisfactorily for all parties.

Dental Coverage

Full coverage dental insurance

Full coverage dental insurance, also called comprehensive dental insurance, means the plan covers some portion of these categories of dental care:
