Almost everything people know about HMOs comes from medical insurance, and almost none of it transfers to dental. A dental HMO is not a stripped-down dental PPO. The two products bill in completely different ways, and the number most people get wrong is not the premium.
All the figures below come from 2026 carrier plan documents and dental-benefits research, checked on September 6, 2026. If you are comparing medical plans, that is a separate question covered in HMO vs PPO.
The One Difference That Matters: Annual Maximum
A dental PPO has an annual maximum, a hard ceiling on what the plan will pay in a calendar year. Hit it and the plan pays nothing more until January, no matter what your mouth needs.
A dental HMO, usually written DHMO or DMO, generally has no annual maximum at all. Delta Dental’s 2026 Florida broker booklet says it in plain language: DeltaCare USA plans “have no deductibles, no annual maximums and set copayments.” NADP, the dental plan industry’s research association, confirms the pattern, noting that DHMOs rarely have an annual maximum.
That is the reverse of the medical world, where an HMO is the restrictive option and the PPO is the generous one. In dental, the DHMO is the one without a spending cap.
The catch is the network. NADP defines dental HMOs as plans that pay for general dentistry “primarily under capitation arrangements with a contracted network of dentists,” meaning your assigned dentist gets a fixed monthly payment per enrolled patient whether you show up or not. You pick one dentist, you use that dentist, and outside an emergency away from home there is no out-of-network benefit at all. If you want the general version of that trade, see in-network vs out-of-network.
How Each One Bills You
| DHMO (DeltaCare USA) | Dental PPO Basic | Dental PPO Premium | |
|---|---|---|---|
| 2026 adult premium, Florida individual | $107.04 per year | $299.40 per year | $664.08 per year |
| Deductible | None | $50 person / $150 family | $50 person / $150 family |
| Annual maximum | None | $1,000 per person | $2,000 per person |
| Preventive care | $0 exam, $20 adult cleaning | 100%, no waiting period | 100%, no waiting period |
| Basic services | Set copay per procedure | 50% after 6 months | 80% after 6 months |
| Major services | Set copay per procedure | Not covered | 50% after 12 months |
| Orthodontics | 75% of the orthodontist’s filed fee | Not covered | 50% after 12 months, $1,500 lifetime cap |
| Out-of-network benefit | None | Reduced | Reduced |

Three things in that table surprise people. The DHMO premium is roughly one sixth of the PPO Premium plan’s. The PPO Basic plan does not cover major services at all. And both PPO plans impose waiting periods, six months for basic work and twelve for major, while the DHMO has none.
A separately published Delta Dental disclosure matrix for the PPO Premium plan confirms the $2,000 annual maximum, the $50 individual and $150 family deductible, and the $1,500 lifetime orthodontic maximum, and adds that the waiting periods are waived with proof of prior coverage. Delta Dental’s 2026 Maryland individual PPO plan shows the classic coinsurance ladder in its purest form: 100% for diagnostic and preventive, 80% for basic, 50% for major, against a $1,000 annual maximum. That 100/80/50 split is the shape most dental PPOs take.
One nuance on the “no maximum” claim. Pediatric dental benefits sold as an essential health benefit work differently: instead of an annual maximum they carry an out-of-pocket maximum, which Delta Dental’s 2026 Florida plans set at $450 for one pediatric enrollee and $900 for two or more, after which the plan pays 100%.
What the Numbers Look Like on Real Procedures
Here is the same set of CDT procedure codes priced four ways. The DHMO column is Delta Dental’s published 2026 Florida copayment schedule. The retail and savings-plan columns are DentalPlans.com’s published sample fee comparison for its Aetna Dental Access plan, a discount plan rather than insurance.
| Code | Procedure | Retail cash (sample) | Dental savings plan | DHMO copay |
|---|---|---|---|---|
| D0120 | Periodic exam | $100 | $35 | $0 |
| D1110 | Adult cleaning | $120 | $67 | $20 |
| D7140 | Simple extraction | $309 | $96 | $40 |
| D3310 | Root canal, front tooth | $1,250 | $504 | $240 |
| D2750 | Crown, porcelain and precious metal | $1,500 | $949 | $425 |
| D5110 | Full upper denture | $1,954 | $1,123 | $495 |

Retail figures are national samples, not a quote from any specific practice. Our own cash-price research puts a crown at $800 to $2,500, a root canal at $700 to $2,500 and a routine cleaning at $75 to $200, so treat any single retail figure as the middle of a wide band.
Take a front-tooth root canal plus the crown that follows it, a very common pairing, and total each route for one year:
- Straight retail: $1,250 plus $1,500 equals $2,750.
- Dental savings plan: $504 plus $949 plus $174.95 in fees equals about $1,628.
- DHMO: $240 plus $425 plus a $107.04 premium equals about $772, with a $85 post and core copay if one is needed.
- PPO Premium, year one: major services are not covered for twelve months, so the $664.08 premium buys nothing toward either procedure.
The DHMO wins that comparison by a wide margin, and it wins immediately because there is no waiting period. That is the honest case for a DHMO, and it is stronger than most comparison articles admit.
Why the Annual Maximum Is the Number People Get Wrong
Dental PPO maximums have barely moved in decades. ADA News, citing NADP data in December 2025, reports that 32.8% of in-network annual maximums fall between $1,000 and $1,500, 48.2% between $1,500 and $2,500, and 17.2% at $2,500 or with no maximum at all. The ADA notes that many plans still promote a $1,000 level set roughly 40 years ago, and in 2024 the association adopted a formal policy opposing annual and lifetime maximums entirely.
Carriers point to utilization. NADP found that from 2014 through 2023, fewer than 5% of enrollees on average reached their annual benefit maximum, and an ADA Health Policy Institute analysis put it at 3.4% reaching the typical maximum with another 3.3% coming within $100 of it.
Both facts are true at once, and that is the trap. The maximum almost never binds, right up until the year you need real work, and then it binds hard. Stack the maximum on top of 50% coinsurance for major services and, as the ADA puts it, patients face a steep bill long before their clinical needs are met.
Two structural notes that make the cap smaller than it looks. The 50% is applied to the plan’s contracted allowance, not your dentist’s list price. And the deductible comes off first, which works the same way it does on the medical side (copay vs coinsurance covers the mechanics).
When Paying Cash Beats Both
For preventive care only, a PPO is usually fine and often free at the chair. For one moderate procedure, the DHMO copay schedule is usually the cheapest insured route. For a large case, run the numbers before you enroll in anything.
Say you need four crowns in a year. At the $1,500 sample retail fee that is $6,000 out of pocket. A PPO Premium plan paying 50% of the contracted allowance stops at its $2,000 maximum, so you cover the rest plus the deductible plus the premium. The same four crowns on the DHMO schedule come to $1,700 plus a $107.04 premium, with nothing capped.
But a dental savings plan, or simply asking the practice for its cash or prompt-pay price, can land in the same territory without locking you to one dentist. Dental savings plans walks through how those work and what they cost, and dental insurance cost covers premiums, waiting periods and missing-tooth clauses across plan types. If money is the binding constraint right now, free dental clinics and dental grants are worth checking before you buy any product.
The one thing to avoid is buying a low-maximum PPO because it feels like real insurance, then discovering in month three that major work has a twelve-month waiting period.
Bottom Line
Pick a DHMO if you have a specific network dentist you are happy with, you want predictable dollar copays, and you expect real work rather than just cleanings. The missing annual maximum is the feature, and the small network is the price.
Pick a dental PPO if dentist choice matters more than the cap, you mostly need preventive care, and you can live with the maximum. Just read the annual maximum, the coinsurance tier for major services, and the waiting periods before you look at the premium.
And if you are facing a big case, price it as a cash patient first. On dental work more than anywhere else in health care, the self-pay number is often the one that wins. For the general version of the network question, see what is a PPO plan.
