Types of Dental Insurance Plans: PPO, HMO, Indemnity & Discount Plans Explained
Updated at June 30, 2026
Key Takeaways
- Most individual dental plans fall into three structures: PPO (choose any dentist, pay more out-of-network), HMO/DHMO (lower premiums, in-network only), and indemnity (fee-for-service reimbursement). Dental discount plans are not insurance but offer the lowest upfront cost with no waiting periods.
- Plan type determines which dentists you can see, how much you pay out of pocket, and whether waiting periods apply — more so than the specific insurer you choose.
- For most self-employed individuals and those buying coverage independently, a PPO is the most flexible starting point. If cost is the primary concern and you have a preferred in-network dentist, an HMO can cut premiums by 40–60%.
The type of dental plan you choose shapes almost every aspect of your coverage: which dentists accept your plan, how much you pay each visit, whether you need referrals, and how long you wait before your plan covers fillings or crowns. Understanding plan structure first — before comparing specific insurers or monthly premiums — is the fastest path to finding coverage that actually works for your situation.
This hub covers the four main dental plan types, explains how each works, and links to in-depth guides on every aspect of dental insurance that affects plan-type decisions: how dental insurance works, what it covers, waiting periods, exclusions, how to compare plans, and how to buy.
What Are the Main Types of Dental Insurance Plans?
Dental insurance in the United States is sold through four primary plan structures. Each one handles the relationship between you, your dentist, and your insurer differently.
- PPO (Preferred Provider Organization) — The most common individual plan type. You can see any licensed dentist; in-network dentists charge negotiated rates, cutting your out-of-pocket costs. No referrals required.
- HMO / DHMO (Dental Health Maintenance Organization) — Lower monthly premiums in exchange for restricting care to an in-network provider list. You choose a primary care dentist and typically need referrals for specialists.
- Indemnity (Fee-for-Service) — The most flexible structure: the plan reimburses a fixed percentage of any dentist's fee regardless of network status. Less common today; premiums are higher.
- Dental Discount Plans — Not insurance. Membership programs ($8–$15/month) that give you access to a network of dentists who charge reduced rates (20–50% off). No waiting periods, no annual maximums, no claims.
PPO Dental Plans
PPO plans are the most widely purchased individual dental plan type in the US. The core feature is network flexibility: you can visit any licensed dentist. When you stay in-network, the insurer has pre-negotiated rates with the dentist, reducing your share of the bill. Going out of network is allowed but costs more — the plan reimburses at a lower "usual and customary" rate and you pay the difference.
Coverage typically follows the 100/80/50 structure: preventive care (cleanings, X-rays, exams) at 100%, basic services (fillings, extractions) at 80% after a deductible, and major services (crowns, root canals, bridges) at 50%. Most individual PPO plans carry a $1,000–$2,000 annual maximum and a 6–12 month waiting period on non-preventive services.
Monthly premiums for individual PPO plans range from $30–$60 for basic coverage to $50–$80 for premium tiers with higher annual maximums or shorter waiting periods. PPO plans work well for self-employed individuals, freelancers, and anyone who values the ability to keep their existing dentist. See PPO vs HMO dental insurance: which type fits your situation for a detailed side-by-side comparison.
HMO / DHMO Dental Plans
HMO dental plans (also called DHMO — Dental Health Maintenance Organization) offer the lowest monthly premiums of any insurance plan type, typically $15–$35 per month for individual coverage. The trade-off is a restricted provider network: you choose a primary care dentist from the plan's list and must use in-network providers for all covered services. Out-of-network care is not covered except in emergencies.
Instead of coinsurance percentages and deductibles, HMO plans often use fixed copays per procedure. A cleaning might cost $0–$15, a filling $20–$50, and a crown $200–$350 — regardless of what the dentist normally charges. This makes costs predictable. Many HMO plans also waive waiting periods entirely, which makes them worth considering if you need basic care soon after enrolling.
HMO plans make the most sense when you live in an area with a strong HMO network, your preferred dentist participates, and cost reduction is more important than provider flexibility. They are less suitable for people who travel frequently or live in rural areas with limited network density.
Indemnity (Fee-for-Service) Dental Plans
Indemnity plans are the oldest and most flexible form of dental insurance. You visit any dentist you choose — there is no network — and submit a claim afterward. The insurer reimburses a fixed percentage of the procedure's "usual, customary, and reasonable" (UCR) fee. If your dentist charges above the UCR rate, you pay the difference on top of your coinsurance share.
Premiums are higher ($50–$100/month for individual coverage) and annual maximums can reach $2,500–$3,000 on better plans. Indemnity plans suit people with long-term relationships with a specific dentist who is not in any major network, or individuals in areas with sparse PPO networks. They are less common today — most major insurers have shifted to PPO and HMO structures — but specialty carriers still offer them.
Dental Discount Plans
Dental discount plans are not insurance. They are membership programs that give you access to a network of participating dentists who have agreed to charge members reduced rates — typically 20–50% below their standard fees. You pay the discounted rate directly to the dentist at the time of service. There are no claims, no deductibles, no annual maximums, and no waiting periods.
Monthly costs range from $8–$15 for individuals. Coverage activates in 1–3 business days, making discount plans the fastest path to reduced-cost dental care. Popular networks include Careington, Aetna Dental Access, and Cigna Dental Savings.

Read: Dental insurance for braces →
How to Choose Between Plan Types
The right plan type depends on three questions:
- Do you have a dentist you want to keep? If yes, verify whether they participate in the plan's network before enrolling. A PPO gives you flexibility to stay with them even if they are out-of-network (at higher cost). An HMO requires switching to an in-network provider.
- How soon do you need non-preventive care? If you need a filling or crown in the next 6 months, look for plans with no or short waiting periods — some HMO plans and select PPO tiers (Spirit Dental, some Humana plans) waive waiting periods entirely. If you only need preventive care now, any plan type works: preventive is covered from day one on virtually every plan.
- What is your budget? HMO plans typically cost 40–60% less per month than equivalent PPO plans. For a healthy individual who primarily needs preventive care and is comfortable with an in-network dentist, an HMO or even a dental discount plan often delivers better value. See average dental insurance cost in 2026 for a full breakdown of what each plan type costs by tier and state.

Frequently Asked Questions
What is the most common type of dental insurance plan?
PPO (Preferred Provider Organization) plans are the most widely purchased individual dental plans in the US. According to the National Association of Dental Plans (NADP, 2025), PPO plans account for approximately 85% of all enrolled dental plan members when including both employer and individual markets. Their combination of network flexibility and broad insurer availability makes them the default choice for most individual buyers.
What is the difference between a PPO and an HMO dental plan?
The core difference is network flexibility vs cost. A PPO lets you visit any dentist (in-network costs less, out-of-network costs more). An HMO restricts you to a specific provider network but charges lower premiums — typically $15–$35/month vs $30–$60/month for a comparable PPO. HMOs often use copays instead of coinsurance and may waive waiting periods, while PPOs typically impose 6–12 month waits on non-preventive services.
Do dental discount plans count as insurance?
No. Dental discount plans are membership programs, not insurance. You pay a monthly fee ($8–$15) for access to a network of dentists who offer reduced rates to members. There are no claims, no deductibles, no annual maximums, and no waiting periods. They are regulated differently from insurance and do not satisfy any insurance requirement. They work well as a standalone option for routine care or as a supplement to an existing plan with coverage gaps.
Which dental plan type has no waiting period?
HMO / DHMO plans most commonly waive waiting periods entirely — you can get fillings and other basic work covered from day one. A small number of PPO plans also waive waiting periods (Spirit Dental Platinum, some Humana tiers), though they charge higher premiums. Dental discount plans have no waiting periods because they are not insurance. Traditional PPO plans almost always impose a 6-month waiting period on basic services and 12 months on major services.
Can I have both a dental insurance plan and a dental discount plan?
Yes, and it can be a smart combination. A dental discount plan can fill coverage gaps left by insurance — cosmetic procedures, implants, or services during waiting periods, for example. The discount plan rate applies to whatever portion your insurance does not pay. Just confirm that your dentist participates in both the insurance network and the discount plan network before combining them.
