The Basic Differences between PPO and HMO Dental Plans
PPO and HMO both refer to the type of dentist network associated with the insurance plan. PPO is an acronym for "Preferred Provider Network" and HMO stands for "Health Maintenance Organization." Today about eight-in-ten private dental plans in the U.S. are PPOs while less than one-in-ten are HMOs. HMOs pay their dentists a set monthly amount for each enrollee regardless of the services they use. A PPO reimburses a dentist based on services rendered.
Typically, an HMO dental insurance plan has a narrow network of participating dentists and services received from out-of-network dentists won't be paid for by the dental plan. A PPO dental insurance plan, in contrast, offers coverage for dental care received outside its network but it comes higher out-of-pocket costs for the plan enrollee. A PPO plan also does not require a referral before going to a dental specialist while an HMO plan will require such a referral from the enrollee's primary care dentist.
Neither HMO nor PPO dental plans have standardized benefits. However, HMO plans in the market seem less likely to offer very limited benefit coverage. Instead, many HMOs provide comprehensive insurance that covers preventive, basic, and major dental services. This is not to say that individual HMO plans always cover more expensive services such as crowns or dental implants, but that that they frequently do.
Among dental plans the network acronyms often have the letter "D" in front of them so instead of PPOs and HMOs, there are DPPO and DHMO plans. Don't worry. The "D" stands for "dental” and the guidance regarding the two network types still applies.
Why PPOs Often Have Higher Premiums
Dental plan premiums vary by several factors:
- The insurance company offering the plan
- The plan's covered services and network type
- The number of people enrolled in the plan (e.g. individual coverage or family coverage)
- The location and ages of the enrollees
With that said, PPOs often have higher premiums than HMOs because PPO enrollees have more freedom with respect to dentist choice and the use of dental services. With respect to the latter issue, instead of a primary care dentist within an HMO deciding whether a specialist referral is necessary, the enrollee in a PPO can make that decision without need of a referral. HMOs not only restrict referrals to the judgment of a primary care dentist, there is also a tendency among HMOs to have fewer in-network providers (i.e. a narrow network).
Dental HMO/PPO Trade-Offs
While the differences between dental HMO plans and dental PPO plans are not especially complicated, the wrong choice can have negative consequences for either your wallet or your oral health.

Frequently Asked Questions (FAQ)
Do HMO dental plans have the same number of participating dentists as PPO dental plans?
HMO plans usually have fewer dentist options than PPO plans. This reduced choice is sometimes referred to as a narrow network.
Do PPO plans have the same out-of-pocket costs as HMO plans?
Out-of-pocket expenses vary by dental plan, whether PPO or HMO. PPOs often have cost-sharing fees that are based on a percentage of the plan’s negotiated price for dental care while HMOs often have a predetermined dollar amount charged as a copayment.
