When you shop for individual dental insurance, almost every carrier offers two plan structures: a PPO or an HMO (called a DHMO in dental). They look similar on a brochure. In practice they price your care in completely different ways, and the cheaper premium is not always the cheaper plan.
How a dental PPO works
PPO stands for Preferred Provider Organization. You can see any licensed dentist, and you do not need a referral to see a specialist. The plan negotiates discounted fees with dentists in its network, so you pay less when you stay in-network. Go out of network and the plan still pays a share, but the coverage percentage drops and you can owe the difference between the dentist’s full fee and what the plan allows.
PPO premiums run higher. Market averages put individual PPO dental plans around $27 per month, with a typical range of about $19 to $70 depending on the carrier and benefit level. Most PPOs have a deductible, commonly $50 per person, and an annual maximum, usually between $1,000 and $2,500. Once the plan has paid out that maximum for the year, the rest is on you until the benefit year renews.
How a dental HMO (DHMO) works
A DHMO, or dental health maintenance organization, assigns you to one primary dentist in its network. You must use that dentist for routine care, and you need a referral from them before the plan will cover a specialist such as an orthodontist or oral surgeon. Care outside the network is generally not covered at all, except for emergencies.
The tradeoff for those restrictions is price. Average DHMO premiums sit around $19 per month, with plans ranging from about $8 to $25. DHMOs usually have no deductible, and many have no annual maximum, which is their standout feature: if you need thousands of dollars of restorative work in one year, the plan keeps paying according to its copay schedule. Instead of coinsurance percentages, DHMOs use fixed copays. You might pay a set dollar amount for a filling or a crown regardless of the dentist’s billed fee.
Cost comparison, side by side
| Feature | Dental PPO | Dental HMO (DHMO) |
|---|---|---|
| Typical monthly premium | $19 to $70, averaging near $27 | $8 to $25, averaging near $19 |
| Deductible | Usually around $50 per person | Usually $0 |
| Annual maximum | $1,000 to $2,500 | Often none |
| Choose any dentist | Yes, best rates in-network | No, assigned network dentist only |
| Specialist referrals | Not required | Required |
| Out-of-network care | Covered at a lower percentage | Not covered except emergencies |
Who actually saves with each plan
A DHMO tends to win for people whose main goal is the lowest predictable cost. The premiums are lower, there is no deductible to clear, and the fixed copays make it easy to know what a procedure will cost before you sit in the chair. If you are comfortable picking a dentist from a smaller network and getting referrals for specialists, the savings are real, roughly $100 to $200 a year in premium alone versus a mid-tier PPO.
A PPO tends to win for people who already have a dentist they trust, who want to see specialists without paperwork, or who travel and need coverage away from home. The flexibility costs more in premiums, and the annual maximum can bite if you need a lot of major work in one year, but you are not locked to a single office.

One more option worth knowing
If premiums for real insurance look steep for the amount of care you use, dental discount plans are a different animal: a yearly membership, usually $80 to $200, that buys you access to negotiated rates without deductibles, maximums, or waiting periods. They are not insurance, and you pay the full discounted fee, but for some people the math beats a PPO.
The bottom line
DHMO plans cost less per month and cap your costs with fixed copays, while PPO plans cost more but let you see any dentist and handle out-of-network care. Pick the DHMO for predictable low costs, or the PPO for freedom of choice. Before you decide, check what dental insurance actually covers, because the fine print on waiting periods and exclusions matters more than the premium difference.
