How Much Does Delta Dental Cover for Braces: Limits and Waiting Periods

Delta Dental does cover braces under most plans that include orthodontic benefits, typically paying 50% of the cost up to a lifetime maximum of $1,000 to $2,500.{¹} The catch is that orthodontic coverage is not automatic. Whether your plan includes it, whether adults are covered, and how much the plan will actually pay depend entirely on the plan your employer chose or the individual policy you bought. Two people who both say they “have Delta Dental” can have very different braces benefits, or none at all.

How Much Delta Dental Pays

The standard orthodontic benefit under Delta Dental PPO and Premier plans is 50% coinsurance.{²} The plan pays half the approved fee, and you pay the other half. Some employer plans are more generous. One Mayo Clinic plan covers orthodontics at 100% up to the lifetime cap,{³} and a University of Texas system plan pays 80%.{⁴}

Every plan also caps what it will pay for orthodontics over a person’s lifetime, and this cap does not reset each year the way regular dental maximums do. Common lifetime maximums fall between $1,000 and $2,500.{¹} Delta Dental of South Dakota cites $1,500 as a typical figure.{⁵}

The lifetime maximum, not the coinsurance percentage, is usually the number that determines what you actually get. Say your plan covers 50% with a $1,500 lifetime maximum, and braces cost $6,000. Half of $6,000 is $3,000, but the cap limits the payout to $1,500. You owe the remaining $4,500.

Delta Dental also doesn’t pay the whole benefit at once. Under many plans, you receive 50% of the total benefit when braces are placed and the remaining 50% twelve months later.{} If the total benefit is $500 or less, it comes in a single payment.{} If your policy ends before treatment finishes, payments stop on the last day of coverage.{⁶}

Does Delta Dental Cover Braces for Adults

Sometimes. Adult orthodontic coverage is available through Delta Dental PPO and DeltaCare USA group plans, and through certain individual plans like the PPO Premium Plan.{⁷} Some employer group plans have no age limit at all.{⁸} Others restrict benefits to patients under 19.{⁹}

If you bought coverage through the Affordable Care Act marketplace, the picture is much worse for adults. Pediatric dental is an essential health benefit under the ACA, so plans for children under 19 often include medically necessary orthodontics at 50%.{} Adult marketplace plans typically do not include any orthodontic coverage.{¹⁰} Delta Dental of North Carolina’s ACA-certified plans, for example, do not cover orthodontics for anyone 19 or older.{²}

What Types of Braces Are Covered

Delta Dental plans that include orthodontic benefits generally cover comprehensive treatment without restricting it to a particular appliance. Invisalign and other clear aligners are explicitly covered under all Delta Dental plans that include orthodontic benefits, up to the lifetime maximum.{¹¹} Because clear aligners usually cost more than metal braces and the dollar cap stays the same, choosing Invisalign generally means paying more out of pocket.{¹²}

Covered services typically include the pre-orthodontic visit, examination and diagnostic records, comprehensive treatment, post-treatment records, and one set of retainers.{⁷} Replacement retainers are not covered.{¹¹} Minor tooth movement procedures are also excluded.

Waiting Periods

Many Delta Dental plans impose a waiting period before orthodontic benefits begin. A 12-month waiting period is common on individual and family plans.{¹³}{¹⁴} Delta Dental of Oklahoma’s individual PPO plan has an 18-month waiting period.{¹⁵} Some employer group plans have no waiting period at all.{¹⁶}

The waiting period can often be waived if you had prior dental coverage with orthodontic benefits for at least 12 continuous months, with no more than a 63-day gap between plans.{¹⁴} A Certificate of Creditable Coverage from your previous insurer is usually the document required.{¹³} Buying a new plan specifically to get braces usually means waiting a year or more before any orthodontic benefit is available.

When “Medically Necessary” Is Required

Plans that restrict orthodontic coverage to medically necessary cases, which especially includes ACA marketplace plans for children, require more than a dentist’s recommendation. Many of these plans use the Handicapping Labio-Lingual Deviation (HLD) Index to score severity, and a score of 26 or higher generally qualifies.{¹⁷} Certain conditions qualify automatically, including cleft palate, deep impinging overbite that destroys soft tissue, severe traumatic deviations, and overjet greater than 9mm with incompetent lips.{¹⁸}

One health insurance analysis estimated that roughly 85% of orthodontic treatment is considered cosmetic rather than medically necessary.{¹⁹} Most children who get braces for typical crowding or alignment would not qualify under these stricter plans. Employer-sponsored group plans, by contrast, often cover orthodontics with no medical necessity requirement.

DeltaCare USA Plans Work Differently

DeltaCare USA is Delta Dental’s HMO-style plan, and it does not use coinsurance percentages. Instead, you pay a fixed copay for braces, and you must use your assigned DeltaCare USA dentist or get a referral. Copays vary widely across plans. One plan lists child orthodontic copays of $1,150 to $1,900 and an adult copay of $2,100.{²⁰} A DeltaCare USA Basic plan in New York lists a $350 copay for pediatric enrollees under 19 and a $3,250 copay for adults.{²¹}

In-Network vs. Out-of-Network Orthodontists

You can visit any licensed orthodontist under most Delta Dental PPO and Premier plans, but using an in-network provider lowers your costs.{¹¹} In-network orthodontists accept Delta Dental’s negotiated fees as their maximum charge, which can save members up to 40% on covered procedures.{²²} Out-of-network orthodontists set their own prices and can balance bill you for the difference between their charge and what Delta Dental reimburses.{²³}

There are practical differences too. In-network orthodontists file claims directly and collect only your share at the time of service. Out-of-network providers often require full payment upfront and leave you to submit the claim.{²²} Some plans also pay a higher coinsurance in-network, such as 60% in-network versus 50% out-of-network under one National University plan.{¹⁶}

Within Delta Dental’s own networks, PPO dentists charge lower fees than Premier dentists. If a PPO plan member sees a Premier orthodontist, the plan may reimburse at the lower PPO fee schedule, leaving the member responsible for a larger share.{²⁴}

What Braces Cost and What You’ll Still Owe

Delta Dental’s share only tells half the story. Orthodontic treatment in the United States averages roughly $3,000 to $7,500 depending on the type of braces and complexity of the case.{²⁵}{²⁶} A general breakdown by type:

Traditional metal braces: $3,000 to $7,500
Ceramic braces: $4,000 to $8,500
Clear aligners such as Invisalign: $3,000 to $8,500
Lingual braces: $8,000 to $13,000

Costs vary by location, the orthodontist’s experience, and treatment length, typically 12 to 36 months. With a typical Delta Dental benefit of 50% coinsurance and a $1,500 lifetime maximum, most patients will have $1,500 covered and owe the rest.

Ways to Reduce What You Pay

Several options can help close the gap between what Delta Dental covers and what braces actually cost.

Health Savings Accounts and Flexible Spending Accounts let you pay orthodontic expenses with pre-tax dollars, saving 20% to 30% depending on your tax bracket. HSA funds roll over year to year; FSAs generally follow use-it-or-lose-it rules with limited carryover. The 2026 contribution limits are $4,400 for individual HSAs ($8,750 for families) and $3,400 for FSAs.{}²⁷
Many orthodontists offer monthly installment plans, often interest-free, that spread costs over the treatment period.{}²⁸
If you’re covered under two group dental plans, the secondary plan may pick up part of the remaining cost after the primary pays. Combined payments cannot exceed the total allowed charge, and a secondary plan with a non-duplication of benefits clause may pay nothing additional.{}²⁹
Because orthodontic treatment often spans more than a year, you can sometimes time the start date to use multiple years of FSA contributions.

How to Confirm Your Own Coverage

Delta Dental operates through independent member companies in different states and offers thousands of distinct plan designs, so the only reliable way to know your exact benefit is to check your own documents. Review your Summary of Dental Plan Benefits, log into your account on your state’s Delta Dental website, or call the number on your member ID card. Before treatment starts, ask your orthodontist to submit a pre-treatment estimate (also called a predetermination of benefits) for any treatment expected to cost more than $250.{¹²} That gives you a written estimate specific to your plan, your provider, and your treatment. Some states go further and require it: Delta Dental of New Jersey mandates prior authorization for all orthodontic services, and skipping it can cost you up to 50% of the covered charges.{³⁰}
