Walk into any Aspen Dental, Heartland Dental, or Great Expressions office as a new patient, and you'll often leave with a treatment plan in the thousands of dollars — even if your prior dentist said your mouth was healthy. The phenomenon is well-documented in Consumer Affairs reviews, BBB complaints, state attorney general investigations, and a 2022 Aspen Dental class action settlement that paid $175 million to affected patients.
This isn't because the individual dentists working at DSO chains are bad people. Most aren't. It's because DSOs — Dental Service Organizations — have a business model that structurally pressures upselling, and the dentists are caught in the middle of it.
Understanding how DSOs work helps patients navigate them (or decide to avoid them) and helps explain why DentalPlanRx specifically avoids recruiting DSO-employed dentists for its partner clinic network.
What a DSO actually is
A Dental Service Organization is a business entity that manages the non-clinical operations of dental practices — marketing, billing, purchasing, HR, facility management — across many locations. The clinical entity is legally separate (usually a professional corporation or PLLC owned by dentists) because most states prohibit non-dentist ownership of dental practices.
The DSO structure emerged in the 1990s and grew rapidly through private equity investment in the 2010s. As of 2024, DSOs operate roughly 25-30% of US dental practices by location, with concentration higher in specific chains:
- Heartland Dental: 1,800+ offices across 39 states (largest DSO by office count).
- Aspen Dental: 1,100+ offices across 46 states.
- Great Expressions Dental Centers: 270+ offices, mostly East Coast.
- Smaller regional DSOs collectively operate hundreds more.
Most DSOs are backed by private equity firms with 4-7 year investment horizons. The investment thesis depends on revenue growth, operational efficiency gains, and eventual sale at a multiple of cash flow — which means internal pressure for increasing revenue-per-patient quarter over quarter.
The economic pressure that drives upselling
DSOs make money by driving procedure volume. Higher production per patient visit equals more revenue. This pressure gets transmitted to individual offices through several mechanisms:
Production quotas
Many DSO practices have explicit or implicit production quotas — dollar targets for treatment plans generated per patient visit. Dentists who consistently produce low treatment plan values (because their patients have healthy mouths) may face pressure from regional managers. Hygienists are often pushed to identify and refer additional billable procedures during cleanings.
Compensation structures tied to production
Staff dentists in DSOs are often compensated on base salary plus percentage of production. A dentist earning $150,000 base plus 5% of production has direct financial incentive to increase treatment plan size. The result is subtle but pervasive — borderline cases get recommended treatment where an owner-operated dentist might have chosen watchful waiting.
Centralized treatment planning pressure
Some DSO chains use centralized treatment planning software that suggests or requires specific procedures based on screening criteria. Hygienist finds a probing depth of 4mm in one spot? Software recommends scaling and root planing. New patient has visible wear? Software flags potential need for restorations. The individual dentist can override, but it's easier to go with the software's recommendation.
New-patient "comprehensive treatment plan" presentations
DSO offices typically have a structured new-patient experience that includes x-rays, extensive examination, and presentation of a treatment plan by a treatment coordinator (often a non-clinical staff member) who uses specific sales techniques to close the treatment. Financing through third-party lenders is offered. Pressure to commit before leaving is common.
This process is efficient at generating revenue but also catches patients who would have been better served by piecemeal care over time, or who don't actually need the volume of work being recommended.
Evidence of the pattern
The Aspen Dental 2022 class action settlement specifically addressed allegations that the company pressured patients into expensive treatment plans, used deceptive pricing tactics, and denied refunds to patients who declined treatment. Without admitting wrongdoing, Aspen paid $175 million to eligible patients and modified some business practices.
State attorneys general have investigated DSO practices in Massachusetts, New York, California, and Texas. A 2020 New York attorney general investigation into Aspen Dental resulted in a $1 million settlement over allegations of deceptive business practices and unauthorized practice of dentistry by non-dentist owners.
Reddit's r/askdentists subreddit regularly features posts from patients who received alarming treatment plans at DSO chains. Common pattern: patient was told mouth was healthy at prior independent dentist; walked into Aspen or Heartland for a cleaning; emerged with a $5,000-15,000 treatment plan and intense pressure to finance it.
Not every DSO patient has a bad experience
To be fair: many patients have perfectly fine experiences at DSO chains. Care quality on delivered procedures is often adequate or good. Many DSO dentists are skilled and ethical. The issue isn't uniform — it's structural, meaning that the pattern emerges in aggregate even though individual interactions may be fine.
Patients most at risk are those who are new to the practice, uninsured (and therefore cash-pay without insurance scrutiny of claims), unable to evaluate treatment plan necessity themselves, and emotionally or financially pressured to accept what's offered.
How to navigate a DSO practice if you use one
- Ask for a written itemized treatment plan with CDT codes. This is your legal right. Don't accept a verbal summary.
- Don't commit during the new-patient visit. Take the plan home. Review it. Get a second opinion before scheduling anything beyond routine cleaning.
- Request your x-rays and clinical documentation for second-opinion purposes. Also your legal right.
- Be skeptical of "limited time" financing offers. Urgency is a sales tactic. Real dental need isn't this time-sensitive.
- If work is genuinely needed, consider getting it done at an independent practice instead. Cash prices are often similar or lower, and the sales pressure is absent.
Why DentalPlanRx only recruits independent dentists
DentalPlanRx's partner clinic network specifically excludes DSO chains. The no-upsell commitment that DentalPlanRx members rely on is much harder to honor when the dentist is operating under DSO production pressure. Independent solo and small group practices have different economics — their incentive is to build long-term relationships with patients, not maximize treatment plan dollars per visit.
This limits our partner network somewhat, especially in areas where DSOs have consolidated a lot of practice locations. It's a deliberate trade-off. DentalPlanRx members should feel confident that when they're routed to a partner clinic, they're not walking into a structural upselling environment.
Bottom line
DSO upselling isn't bad luck. It's the predictable outcome of the DSO economic model. Patients don't need to avoid DSOs entirely, but should be aware of the pattern and take protective measures — written estimates, second opinions, no pressure commitments. For patients who want to avoid the dynamic entirely, independent dental practices and services like DentalPlanRx that partner only with independents are the safer structural choice.
