Best Dental Insurance for Adult Orthodontics: Complete 2026 Guide
Considering orthodontic treatment as an adult but worried about the $3,000 to $8,000+ price tag? You're not alone. More adults than ever are seeking straighter teeth—whether for cosmetic reasons, to fix bite issues, or to improve overall oral health.
The challenge? Most dental insurance plans don't cover adult orthodontics. But some do, and finding the right plan can save you thousands. This guide breaks down everything you need to know about dental insurance for adult orthodontics in 2026.
Key Takeaways
- Coverage is limited: Most plans only cover orthodontics for children under 18
- Lifetime maximum: Plans typically pay $1,000-$3,000 total for orthodontics
- Co-insurance: Most plans cover 50% of treatment costs up to the maximum
- Waiting periods: Expect 6-24 months before benefits activate
- Top insurers: Cigna, Guardian, and Anthem rated best for orthodontic coverage
Why Dental Insurance for Adult Orthodontics Matters
Adult orthodontic treatment is a significant investment. According to the American Dental Association, the average cost of braces ranges from $2,815 to $5,605 without insurance—and adults typically pay more than adolescents due to more complex treatment needs.
Unlike children's orthodontics, which is often considered medically necessary, adult treatment is frequently classified as "cosmetic" by insurers. This distinction matters because:
- No government mandate: Unlike pediatric dental coverage under the ACA, adult orthodontics has no coverage requirements
- Employer plans vary widely: Some include adult orthodontic benefits, many don't
- Individual plans are limited: Finding standalone coverage for adult orthodontics is challenging
The right insurance plan can reduce your out-of-pocket costs by $1,000 to $3,000—but only if you understand how coverage works and plan ahead.
The Challenge: Adult Orthodontic Coverage is Limited
Here's the reality most adults discover too late: orthodontic coverage is typically limited to patients under age 18. According to Forbes Advisor's analysis of 37 dental insurance plans, adult orthodontic coverage is the exception, not the rule.
⚠️ Important: Before enrolling in any dental plan for orthodontic coverage, explicitly ask: "Does this plan cover orthodontics for adults over age 19?" Don't assume—verify in writing.
Insurance providers that may offer adult orthodontic coverage include:
- Anthem
- Aflac
- Cigna
- Humana
- UnitedHealthcare
- Delta Dental (some plans)
- Guardian
- MetLife (some plans)
Coverage availability varies by state, employer, and specific plan tier. Always verify before enrolling.
What to Look For in an Orthodontic Insurance Plan
When evaluating dental insurance for adult orthodontics, focus on these five critical factors:
| Factor | What to Look For | Typical Range |
|---|---|---|
| Adult Coverage | Explicit coverage for ages 19+ | Yes/No (verify!) |
| Lifetime Maximum | Total orthodontic benefit over policy life | $1,000 - $3,000+ |
| Co-insurance | Percentage plan pays (you pay the rest) | 50% (standard) |
| Waiting Period | Time before orthodontic benefits activate | 6 - 24 months |
| Monthly Premium | Your monthly cost for coverage | $30 - $75+ |
Understanding Lifetime Maximum vs. Annual Maximum
This distinction confuses many patients:
- Annual Maximum: Total the plan pays for ALL dental services in one year (typically $1,000-$2,000). Resets each year.
- Lifetime Orthodontic Maximum: A separate, one-time cap specifically for orthodontic treatment. Does NOT reset annually.
These are usually separate pools of money. Your orthodontic treatment draws from the lifetime orthodontic maximum, not your annual maximum for cleanings and fillings.
Top Insurance Providers for Adult Orthodontics
Based on Forbes Advisor's 2025 analysis of 37 dental insurance plans:
| Provider | Best For | Key Advantage |
|---|---|---|
| Cigna | Best overall coverage | Higher lifetime maximums, broad network |
| Guardian | Best for costs | Competitive premiums with solid benefits |
| Anthem | Shorter waiting period | Some plans with reduced or no waiting periods |
Remember: The "best" insurer depends on your specific situation. A plan with a higher premium but shorter waiting period might be better if you want to start treatment soon.
Understanding the Coverage Math
Let's break down how orthodontic insurance actually works with a real example:
Example: $5,000 Invisalign Treatment
- Treatment cost: $5,000
- Plan co-insurance: 50%
- Lifetime orthodontic maximum: $1,500
- Insurance pays: 50% of $5,000 = $2,500, BUT capped at $1,500 maximum
- Actual insurance payment: $1,500
- Your out-of-pocket: $3,500
The lifetime maximum is the limiting factor. Even though the plan "covers 50%," you only receive the lesser of 50% or the lifetime maximum.
Is Insurance Worth It? Do the Math
Before enrolling, calculate your actual benefit:
Cost-Benefit Analysis
- Monthly premium: $50
- Waiting period: 12 months
- Premiums paid during waiting period: $50 Ă— 12 = $600
- Lifetime orthodontic maximum: $1,500
- Net benefit: $1,500 - $600 = $900 savings
In this example, insurance saves you $900. But if the waiting period were 24 months, you'd pay $1,200 in premiums for a $1,500 benefit—only $300 net savings. Sometimes paying out-of-pocket or using financing is more cost-effective.
How to Optimize Your Orthodontic Coverage
Maximize your benefits with these strategies:
- Plan ahead for waiting periods: Enroll 12-24 months before you plan to start treatment
- Get a pre-treatment estimate: Have your orthodontist submit your treatment plan to insurance for a "pre-determination of benefits" before starting
- Use in-network providers: PPO plans pay more for in-network orthodontists
- Combine with HSA/FSA: Use pre-tax dollars to pay your out-of-pocket portion, saving 20-30%
- Check spouse's plan: If your spouse has dental coverage, compare both plans—you may be able to coordinate benefits
- Review during open enrollment: Employer plans change annually; check if better orthodontic coverage is available
Alternatives If Insurance Doesn't Cover You
If you can't find affordable orthodontic insurance, consider these options:
- In-house payment plans: Many orthodontists offer 0% interest financing over 12-24 months
- CareCredit or Lending Club: Third-party healthcare financing with promotional 0% APR periods
- Dental discount plans: Not insurance, but membership programs offering 10-60% off dental services
- Dental schools: Orthodontic residency programs offer treatment at 30-50% reduced rates
- HSA/FSA only: Even without insurance, you can use pre-tax dollars to reduce effective cost by 20-30%

FAQ: 12 Questions About Orthodontic Insurance
There's no single 'best' plan—it depends on your needs. Forbes Advisor rates Cigna as best for coverage, Guardian as best for costs, and Anthem for shorter waiting periods. Compare lifetime maximums ($1,000-$3,000+), waiting periods (6-24 months), and monthly premiums before choosing.
Many dental plans do NOT cover orthodontics for adults (age 19+). Coverage is more common for children under 18. However, some PPO plans and supplemental orthodontic plans do offer adult coverage—you must specifically verify this before enrolling.
Most plans with adult orthodontic coverage pay 50% of treatment costs, up to a lifetime maximum of $1,000-$3,000. For example, if braces cost $5,000 and your plan has a $1,500 lifetime max at 50%, insurance pays $1,500 and you pay $3,500.
Yes, most dental plans with orthodontic benefits treat Invisalign and traditional braces equally. The same lifetime maximum and co-insurance percentage apply regardless of treatment type. Always verify with your specific plan, as some older policies may exclude clear aligners.
A waiting period is the time after enrollment before orthodontic benefits become active—typically 6 to 24 months. During this period, you pay premiums but cannot use orthodontic benefits. Some plans offer no waiting period, but these usually have higher premiums.
Annual maximum is the total your plan pays for ALL dental services in one year (usually $1,000-$2,000). Lifetime orthodontic maximum is a separate, one-time cap specifically for orthodontic treatment over your entire coverage period (typically $1,000-$3,000).
Yes! Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) can be used for orthodontic expenses. This allows you to pay with pre-tax dollars, effectively saving 20-30% depending on your tax bracket. You can combine this with insurance benefits.
Do the math first. If a plan costs $50/month with a 24-month waiting period and $1,500 lifetime max, you'll pay $1,200 in premiums before benefits start, then receive $1,500—a net benefit of only $300. Sometimes paying out-of-pocket or using financing is more cost-effective.
Supplemental orthodontic insurance is additional coverage you purchase on top of your regular dental plan specifically for orthodontic treatment. It can increase your total coverage amount but adds another monthly premium. Evaluate if the extra cost is worth the additional benefit.
Contact your insurance carrier directly and ask: (1) Does the plan cover orthodontics for adults over 19? (2) What is the lifetime orthodontic maximum? (3) What is the co-insurance percentage? (4) Is there a waiting period? (5) Are clear aligners like Invisalign covered?
PPO plans typically cover 50% of orthodontic costs and allow you to see any orthodontist (though in-network saves money). DHMO plans require you to use in-network providers only, offer set copays, and generally have lower premiums but less flexibility.
Enroll 6-24 months before your planned treatment start date to get past waiting periods. If your plan has a 12-month waiting period, enroll at least 13 months before you want to begin treatment. Review benefits annually during open enrollment.
In Summary
Finding dental insurance that covers adult orthodontics requires research and planning. While coverage is limited compared to children's benefits, the right plan can save you $1,000-$3,000 on treatment. Key steps: verify adult coverage explicitly, understand lifetime maximums and waiting periods, do the cost-benefit math, and consider combining insurance with HSA/FSA funds for maximum savings.
