TL;DR
- Top standalone picks: Delta Dental, Guardian, Spirit Dental, Ameritas, and Cigna
- Comprehensive plans average $47–$52/month; preventive-only runs $26–$29/month
- Annual maximums typically span $1,000–$5,000 by carrier and tier

- Medicare Advantage and ACA plans often bundle dental at little or no extra cost
Overview of Dental Insurance in the U.S. Market
Dental insurance is coverage that offsets the cost of exams, fillings, and larger procedures — separate from your medical plan. Standalone dental plans (SADPs) matter most for people without employer-sponsored benefits, including the self-employed and early retirees.
Nearly 1.2 million adults enrolled in standalone dental plans through federal marketplaces in 2023, though overall take-up dropped from 16.2% in 2018 to 11.5% in 2023 (Health Affairs, 2024). Adults aged 55–64 buck that trend, with enrollment climbing to 27.6%.
The comparisons below rank carriers on premiums, coverage depth, and network fit so you can match a plan to your budget and care needs.
Best Dental Insurance Companies in the U.S.
We looked at premiums, coverage percentages, waiting periods, and annual maximums: the four factors that actually determine whether a plan pays off.
Delta Dental
Delta runs the largest dental network in the country, available through employers and individual marketplace plans alike. Its PPO Premier plan delivers strong preventive coverage and broad provider access.
| Feature | Details |
|---|---|
| Average Monthly Premium | $31 (Basic) to $68 (Premier) |
| Coverage Highlights | 100% preventive, 80% basic, 50% major (Premier) |
| Waiting Periods | None for preventive; 6 months for basic/major |
| Annual Maximum | $1,000 (Basic) to $2,000 (Premier) |
Premier also covers orthodontia at 50% with no age limit, though rates and benefit schedules vary by state (Forbes Advisor, 2025).
Guardian
Guardian pairs competitive pricing with perks that most insurers skip, like whitening coverage.
| Feature | Details |
|---|---|
| Average Monthly Premium | ~$56 (Diamond plan) |
| Coverage Highlights | 80% basic (no wait), 50% major, $1,500 annual maximum |
| Unique Perk | Teeth whitening at 50% after 6 months, $500/year cap |
Implants come with a $1,000 lifetime maximum, and major-service waits typically run 12 months.
Spirit Dental
Spirit built its reputation on day-one coverage, with no waiting for basic or major services on most plans.
| Feature | Details |
|---|---|
| Average Monthly Premium | $16-$42 depending on tier |
| Waiting Periods | None |
| Annual Maximum | $1,500 to $5,000 |
The Pinnacle PPO 5000 plan, its top tier, covers implants and child orthodontia. A Forbes-cited Spirit Core PPO example showed basic coverage climbing from 50% in year one to 80% by year three, a common trade-off for skipping the wait.
Ameritas
Ameritas targets people who need care now, not in six months.
| Feature | Details |
|---|---|
| Average Monthly Premium | ~$62 (PrimeStar Complete) |
| Coverage Highlights | 80% basic in-network (year one), rising to 90% |
| Best For | No-waiting-period seekers |
Its annual maximum starts at $2,500 and jumps to $3,000 after year one, one of the higher ceilings among plans reviewed here.
Cigna Dental
Cigna combines health and dental products, with orthodontic coverage for both adults and kids.
| Feature | Details |
|---|---|
| Average Monthly Premium | $19-$54.66 depending on plan category |
| Coverage Highlights | Orthodontia covered at 50%, $1,000 lifetime max |
| Waiting Periods | 6 months basic, 12 months major/ortho |
Cigna's Advance plans skip waiting periods for most classes, though implants still carry a 12-month wait and $2,000 lifetime cap (Cigna, 2025).
Beyond these five, HealthSpring (formerly Cigna Dental) and UHOne offer no-waiting-period individual plans in select states, including Texas and Florida. HealthSpring provides up to $5,000 in annual coverage and access to a network of 85,000+ dentists.
How Much Does Dental Insurance Cost & What It Covers
Nationally, comprehensive dental plans average $47-$52/month, while preventive-only coverage runs $26-$29/month (Forbes Advisor, 2024). Your actual premium depends on:
- Plan type — PPO vs. HMO vs. discount-style plans
- Coverage level — preventive-only versus comprehensive
- Age — older applicants often pay more
- Deductible and coinsurance — higher deductibles usually mean lower monthly premiums
- State of residence — rates vary widely by ZIP code
Most plans divide services into three tiers:
- Preventive — cleanings, exams, X-rays (often covered at 100%)
- Basic — fillings, extractions, deep cleanings (typically 50-80%)
- Major — crowns, root canals, implants, dentures (usually 50% or less)
Common exclusions include cosmetic dentistry, pre-existing dental damage, and teeth whitening (unless specifically listed as a perk). Many plans also set an annual benefit maximum, so once you hit the cap, you pay the rest out of pocket for that year.
Those limits matter when real treatment bills show up. A root canal without insurance runs $500 to $1,500 depending on tooth location, with back teeth costing more than front teeth (Forbes Advisor, 2024). At 50% major-service reimbursement, insurance still saves hundreds, but it does not eliminate the bill entirely.
How We Chose the Best Dental Insurance Companies
A common mistake: shopping by premium alone and ignoring waiting periods or annual maximums. A cheap plan with a 12-month wait on major work doesn't help if you need a crown next month.
To avoid that trap, we ranked plans on the factors that actually affect what you pay and when care starts:
- Monthly cost relative to coverage
- Annual maximum payout
- Waiting period length (or lack thereof)
- Reimbursement percentages for basic and major services
- Orthodontia availability and caps
Finding the Right Coverage Beyond Standalone Dental Plans
Standalone dental isn't the only path to coverage. Many Americans get dental benefits bundled into Medicare Advantage or ACA marketplace plans alongside medical, vision, and hearing benefits.
TrueCost Group helps you compare these bundled options. Qualifying shoppers often pay $0–$50/month in premiums. That comparison matters most if you're:
- Turning 65 and evaluating Medicare Advantage plans
- Uninsured and may qualify for a $0/month marketplace plan
- Comparing standalone dental against a bundled plan that already includes it
Before you buy dental on its own, compare it with a comprehensive plan that may cover medical and dental together for less.
Conclusion
The "best" dental insurance depends on your priorities: lowest premium, fastest access to major care, or the highest annual maximum. Compare plans carefully, confirm your dentist is in-network, and weigh the monthly premium against what you'd actually pay out-of-pocket without coverage.

Frequently Asked Questions
How much is most dental insurance a month?
Comprehensive plans average $47-$52/month, while preventive-only plans run closer to $26-$29/month. Actual pricing depends on your state, age, and plan tier.
What dental insurance has the best coverage?
Spirit Dental's Pinnacle PPO 5000 offers the highest annual maximum ($5,000) among plans reviewed. Delta Dental Premier and Ameritas also offer strong major-service reimbursement with no or short waiting periods.
What's the most dental insurance will cover?
Annual maximums typically range from $1,000 to $5,000 per person. Even top plans usually cap major-service reimbursement around 50%, meaning you'll still pay a share out-of-pocket.
Why is my root canal $3,000?
Cost depends on tooth location and complexity: back teeth cost more than front teeth, and specialist fees add up. Insurance reimbursement, often capped at 50% for major services, won't cover the full bill.
Can you buy standalone dental insurance?
Yes. Standalone dental plans are sold directly through carriers like Delta Dental and Spirit, or through ACA marketplaces and licensed brokers who compare multiple carriers for you.
Is dental insurance worth purchasing?
For most people needing regular cleanings and occasional fillings, yes. Premiums are often lower than the cost of one major procedure. If you rarely need dental work, a low-cost preventive-only plan may make more sense.
