# DSO economics

> Dental-specific operating economics for DSO diligence: hygiene and recall, benefit limits, patient pay, operatories, acquisition underwriting, transaction consideration, and fee constraints.

DSO underwriting must model the dental facts that a generic medical-practice model can miss: hygiene and recall, CDT-level fee schedules and write-offs, annual benefit limits, patient collections and financing, laboratory and supply costs, operatory capacity, active treatment, and provider retention. [Where the profit lives](/concepts/finance/where-the-profit-lives) separates practice, support-company, and consolidated economics.

## The practice P\&L

Published operator benchmarks place general-practice overhead and major cost categories in broad ranges, but definitions, specialty, owner labor, geography, payer mix, and accounting policy move the result materially.<sup>1</sup> Underwrite from the target's adjusted-production, collections, write-offs, staffing, laboratory, supply, occupancy, and provider-compensation data. Dental revenue can include fee-for-service, PPO, DHMO or other capitated arrangements, Medicaid delivery systems, membership plans, financing, and patient pay; do not infer minimal payer risk from the specialty label.

Two line items reward scale directly: **supplies and lab work** are large, negotiable costs where central purchasing produces immediate synergies, and **marketing** drives new-patient volume more directly in dentistry than in referral-driven medical specialties.

## Hygiene and recall create recurring demand, not guaranteed revenue

Industry surveys often place hygiene around **25–35% of general-practice production**, but specialty, coding, staffing, patient mix, and the definition of production matter.<sup>2</sup> A recall system can support repeat preventive visits and clinically appropriate diagnosis; it is not an annuity, and forecasts should account for attrition, scheduling capacity, eligibility, benefit limits, and patient acceptance.

This is why hygiene reappointment rate and recall effectiveness are the operational metrics DSOs standardize hardest, and why hygiene shows up in [practice acquisition diligence](/guides/growth/acquire-a-dental-practice) as its own workstream. It is also, run badly, a compliance surface: scaling-and-root-planing rates and hygiene production incentives appear in the [enforcement record](/reference/legal/dso-enforcement-tracker), and the 2026 California Aspen settlement specifically banned per-sale incentive payments to hygienists.<sup>3</sup>

## Revenue is capped per patient, per year

Many commercial dental plans use an **annual maximum**, often in a range such as $1,000–$2,000, but limits and designs vary and do not describe every Medicaid, DHMO, self-funded, or supplemental product.<sup>4</sup> Consequences for the model:

* **Patient volume and active-patient count matter, but so do service mix and capacity.** Define “active,” cohort retention, recall completion, provider capacity, and treatment acceptance rather than relying on one growth driver.
* **Patient collections require a deliberate workflow.** Once the maximum is exhausted, the remaining covered balance may become patient responsibility under the plan and contract. Treatment-plan presentation, time-of-service collection, and financing options affect whether patients can proceed with major care.
* **The cash and membership economy is large.** Out-of-pocket payment is the largest single source of US dental spending, ahead of private insurance.<sup>5</sup>

## Capital requirements

Third-party 2024–2026 construction guides publish wide operatory and de-novo cost ranges; use them only as a reasonableness check against location-specific design, construction, equipment, imaging, IT, permitting, financing, and contingency bids.<sup>6</sup> Some branded groups use de novos heavily: Heartland reported 38 de-novo openings and 13 affiliations in the first half of 2025.<sup>7</sup> That company-specific period does not establish a market-wide cost or growth rule.

## Do not underwrite automatic multiple expansion

Transaction advisers publish different 2024–2026 EBITDA-multiple ranges for single practices, groups, and platform assets.<sup>8</sup> Those are broker- or adviser-reported observations, not appraisals or guaranteed tiers. Any valuation difference depends on earnings quality, scale, diversification, governance, growth, debt markets, provider retention, legal structure, and buyer competition. Model no automatic “same EBITDA, higher multiple” outcome.

Most tracked 2025 dental private-equity transactions were add-ons to existing platforms, which suggests that unit addition remains a major growth channel.<sup>9</sup> Major DSOs do not publish comparable same-store figures, so treat unsupported industry benchmarks cautiously.

## The deal structures selling dentists actually see

Transaction advisers describe several recurring consideration and retention structures; the names are not standardized and the ownership path must be lawful in the practice's state.<sup>10</sup>

| Structure             | Mechanics                                                                                                                                                                                         |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Full affiliation**  | Dentist sells the whole economic interest and signs on as an employed clinician, or transitions out                                                                                               |
| **Joint venture**     | Dentist sells 60–90% for cash and **retains 10–40% equity at the practice level**, with pro-rata distributions                                                                                    |
| **Equity rollover**   | Dentist sells 100% of the practice and receives 15–40% of consideration in **parent-company (holdco) units**; returns may depend on a later recapitalization or sale                              |
| **Sub-DSO**           | Equity held in a mid-tier holding company between the practice and the parent, sometimes with a substantial interest retained by the selling doctor group; often used for multi-practice founders |
| **Direct investment** | Large groups take institutional capital into the operating company directly                                                                                                                       |

Transition advisers publish illustrative cash, rollover, earnout, employment-term, and recapitalization ranges.<sup>10</sup> Treat them as sales-market context, not a term sheet. For every security or retained interest, map the issuer, class, waterfall, distributions, dilution, repurchase rights, vesting, forfeiture, tax treatment, information rights, transfer limits, and the possibility that no liquidity event occurs.

One common architecture allocates permitted nonclinical assets and services to a support company and licensed care to a practice entity under an MSA. State dental law can reach premises, equipment, workforce, records, fees, accounts, and ownership differently, so do not use that allocation as a national closing schedule. See [Draft a management services agreement](/guides/agreements/draft-a-management-services-agreement) and [Acquire a dental practice](/guides/growth/acquire-a-dental-practice).

## The fee, under new constraints

Everything on [Set the management fee](/guides/agreements/set-the-management-fee) applies. The 2015 New York and 2026 California Aspen resolutions imposed state- and party-specific terms involving revenue-dependent fees.<sup>3</sup> Separately, Nevada, New Jersey, New York, and North Carolina expressly restrict specified dental compensation formulas, and Maryland uses a distinct fixed-compensation pathway. Flat and cost-plus formulas are not automatic safe harbors; test services, actual control, calculation, fee-splitting, referral, tax, and any fair-market-value requirements.
