# The corporate practice of dentistry doctrine

> The state-law prohibition on lay ownership and control of dental practices: why 'owning or operating a dental office' is itself the practice of dentistry in many states, how courts measure control, and the DSO registration layer on top.

The **corporate practice of dentistry (CPOD)** doctrine is the state-specific body of law governing whether and how lay entities may own a dental practice, employ dentists, or control dental operations. In many states the rule is express and statutory; in others it comes through professional-entity law, board rules, or case law, and the consequences range from discipline or contract invalidity to criminal penalties.

## The doctrine is usually written into the statute

Medicine's parallel doctrine, the corporate practice of medicine, is [covered on the MSO-PC Wiki](https://mso.getlemma.com/concepts/model/cpom). It is often inferred from licensing acts, board guidance, and case law. Dental practice acts more often place the prohibition in the **statutory definition of practicing dentistry** itself. Three examples show the pattern:

| State              | Provision                      | What it says                                                                                                                                                                                                                                      |
| ------------------ | ------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Texas**          | Tex. Occ. Code § 251.003(a)(4) | A person "practices dentistry" if the person "owns, maintains, or operates an office or place of business in which the person employs or engages under any type of contract another person to practice dentistry"<sup>1</sup>                     |
| **Washington**     | RCW 18.32.020(3), .675         | Owning, maintaining, or operating a dental office is within the practice definition, while § 18.32.675 creates separate permissions for specified assets other than records, nonlicensed personnel, support services, and agreed fees<sup>2</sup> |
| **North Carolina** | N.C. Gen. Stat. § 90-29(b)(11) | Practicing dentistry includes one who "owns, manages, supervises, controls or conducts … any enterprise wherein" dental acts are performed<sup>3</sup>                                                                                            |

In proprietor-clause states, specified ownership or operating conduct can itself fall within the practice of dentistry. The exact verbs and exceptions matter: Washington, for example, combines a proprietor definition with express support-company permissions. This is why dental diligence maps who owns or leases each asset, employs each workforce category, holds records authority, contracts with payers, and controls accounts instead of treating “nonclinical” as a nationwide answer. See [DSO case law](/reference/legal/dso-case-law).

The consequences can be criminal. In Texas, unlicensed practice of dentistry is a **third-degree felony, each day a separate offense**.<sup>1</sup> Washington makes a corporation's practice or solicitation outside § 18.32.675's permissions and exceptions a gross misdemeanor.<sup>2</sup> The doctrine can also reach the licensee: from *Painless Parker* (1932) forward, boards have disciplined dentists for participating in prohibited corporate arrangements.<sup>4</sup>

## What "control" means: the questions a board asks

The analysis does not stop with the stock certificate. Statutes, courts, boards, and enforcement settlements also examine **functional control**. The table turns recurring dental authorities into operator questions; it does not imply that every state answers each question the same way or that every cited matter produced a judicial holding:

| The question                                                                        | What the operator must establish                                                                                                                                                           | Where it was tested                                                                                                                                                                                                                                                                                          |
| ----------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Who employs the dentists, hygienists, assistants, and other clinical personnel?** | The employer and licensed supervisor permitted or required for each role under that state's dental and entity law                                                                          | *State v. Bailey Dental Co.* (Iowa 1931) treated the company's employment of dentists as part of unlicensed practice under the law then at issue. The 2015 New York Aspen settlement prohibited the DSO conduct alleged there; it is not a nationwide staffing rule<sup>5</sup>                              |
| **Who owns, controls, and may access the patient records?**                         | The person or professional entity required by the state's dental-record law; DSO access only for lawful support functions                                                                  | Nevada's support-services safe harbor expressly excludes “the ownership of the clinical records of patients” from what a lay entity may hold; Colorado's 2025 act guarantees licensees immediate record access<sup>6</sup>                                                                                   |
| **Who controls the account receiving patient and payer funds?**                     | The enrolled or contracting entity, authorized signatories, DSO access, sweep mechanics, and permitted uses must align with payer instructions, entity separateness, and state control law | *In re OCA* (5th Cir. 2008) treated the orthodontists' inability to withdraw funds as one control lever in the complete arrangement. The New York settlement imposed account-access restrictions for the conduct it resolved<sup>7</sup>                                                                     |
| **Who can remove or replace the practice owner?**                                   | Any successor must be eligible under the state and entity form, and the triggers, decision-maker, timing, valuation, and transfer mechanics must preserve the authority state law requires | The 2026 California Aspen settlement restricts DSO owner-replacement rights. The unpublished, nonprecedential *Galkin* decision upheld the judgment on its record, where licensee-only succession and other safeguards were relevant facts. It did not approve succession agreements nationwide.<sup>8</sup> |
| **Who does the public think provides the care?**                                    | The provider identity, practice owner, trade name, and required disclosures must match state advertising law and the actual delivery model                                                 | *Winslow* (Kan. 1924) and *Hannon* (N.Y. 1901) address trade-name or holding-out facts under their governing law; the Aspen settlements impose matter-specific advertising terms<sup>9</sup>                                                                                                                 |

Three emphases from the cited dental authorities sharpen the analysis:

1. **Control is assessed as a whole.** The Fifth Circuit in *In re OCA* considered control over facilities, equipment, staff, billing, bank accounts, and forty-year contract terms. It held that the dentists "were essentially only left with control over diagnosing and treating their patients."<sup>7</sup>
2. **Reserved control can matter.** In *Art Center Holdings v. WCE*, the California AG argues that a lay entity "may not exercise, or even reserve" control rights. Under that position, an unused contractual power may still count.<sup>10</sup>
3. **The whole arrangement is the unit of analysis.** From *Painless Parker* ("the law does not assume to divide the practice of dentistry into such departments") to *In re OCA*, courts read the contracts together. Individually defensible agreements can add up to an illegal scheme.<sup>4</sup>

This is what the [CPOD self-audit](/guides/compliance/run-a-cpod-self-audit) walks through, question by question. On the money-flow question specifically, see [Move money between DSO and PC](/guides/banking/move-money-dso-pc).

## Institutional and ownership alternatives are profession-specific

Medical corporate-practice statutes often create hospital or health-system pathways. Dental statutes use their own exception lists. Depending on the state, those lists may include hospitals, nonprofit or charitable clinics, federally qualified health centers, schools, government programs, employer-provided care, or other named facilities. A medical exception does not automatically cover dental services, and an institution's ability to operate a dental clinic does not automatically authorize an investor-owned practice.<sup>2</sup>

For an investor-backed group in a restrictive state, the support-organization-plus-professional-entity architecture is the common route. It is not the only lawful dental model nationwide: permissive states, registered or licensed lay-owner states, capped-minority ownership, dentist-owned groups, and institutional exceptions produce different entity maps. See [DSO vs. MSO](/concepts/model/dso-vs-mso) and [Alternatives to the DSO model](/concepts/model/alternatives-to-the-dso-model).

## The registration layer: states that regulate DSOs by name

Dentistry also has a profession-specific filing and contract layer. Texas and Kansas register DSOs; Nevada requires a dental-practice business manager to register information with the Board; Arizona registers a business entity that offers dental services; and New Mexico licenses the qualifying non-dentist owner. Illinois' practice act expressly carves out compliant “dental management service organizations” while barring non-dentist control of clinical judgment. Colorado's adopted Rule 1.7 text states that its provisions take effect January 1, 2027. Its paragraph (F) provides a real-property-only lessor exclusion from proprietor status when that person does not also lease or provide dental material or equipment.<sup>11</sup><sup>12</sup>

The full state-by-state picture, with pinpoints, lives in [DSO laws by state](/reference/legal/dso-laws-by-state); the compliance task lives in [Register a DSO](/guides/compliance/register-a-dso). Forming the professional entity correctly is not sufficient if the state separately regulates the DSO, manager, dental business entity, non-dentist owner, facility, or trade name.

## Three layers to check in any state

1. **The CPOD doctrine:** may a lay entity own or control a dental practice, and does the practice act define that conduct as dentistry?
2. **Professional-entity rules for dentistry:** which forms are available, who may own them, and what happens when a dentist-owner dies. Some states permit hygienist or other-licensee minority ownership, while a few permit lay ownership.
3. **DSO-specific statutes:** registration, disclosure, proprietorship restrictions, or enumerated permissible services.

Check each issue against the **dental board's materials and the dental practice act**. Dentistry and medicine are regulated separately and can diverge within the same state. Oregon's 2025 management-entity statute excludes dental practices, while California's SB 351 includes them alongside medical practices.<sup>13</sup>

## What is changing right now

The dental doctrine is in a codification and enforcement wave:

* **California's SB 351 (effective January 1, 2026)** expressly applies to dental practices. Its enumerated restrictions address interference with professional judgment and control over billing, coding, equipment selection, and clinical staffing by private equity groups and hedge funds.<sup>13</sup>
* **The 2026 California Aspen Dental settlement** imposed restrictions addressing succession control, revenue-based fees, practice real estate, sales incentives, and clinician noncompetes; it is a settlement, not an appellate holding.<sup>8</sup>
* **Colorado's adopted Rule 1.7 text** states that its provisions take effect January 1, 2027 and preserves the paragraph (F) real-property-only lessor exclusion described above.<sup>12</sup>
* **North Carolina changed its review procedure**: S.B. 257, signed July 7, 2026, eliminated the dental board's mandatory pre-execution review of management arrangements. The statute's substantive restrictions and conspicuous-warning requirement remain separate questions.<sup>3</sup>
