Dental Practice Ownership vs DSO Statistics 2026: Solo, Group & Corporate Trends

What's in This Guide

Ownership: Still the Majority, But Falling

Practice ownership remains the norm in dentistry, but the trend line is unmistakably downward, and it has been for two decades. The ADA Health Policy Institute, the authoritative source, tracks the decline clearly.

The share of dentists who own their practice fell to 73% in 2023 from 85% in 2005. The ADA is careful to note that ownership is being delayed rather than abandoned, most dentists still eventually become owners, just later in their careers than previous generations. But the direction is consistent across every recent dataset, and it reflects a structural shift in how dental care is organized and financed, not a temporary blip.

Solo vs Group Practice

The clearest casualty of consolidation is the solo practice. Where the lone-dentist office once dominated, group models of every size have taken share.

Solo practice has declined from about 67% of dentists in 2005 to roughly 50.2% in 2024, while small group practices of 2 to 9 dentists account for about 35.6% and larger multi-location organizations make up the rest. Viewed from the other side, roughly two in three dentists now work in a group setting of some size. The logic is operational: staffing scale, shared overhead, group purchasing, and technology investment are all easier to sustain across multiple dentists than alone, which is exactly why the average practice increasingly employs more than one clinician.

DSO Affiliation Rates

The engine of much of this consolidation is the Dental Service Organization. A DSO is a company that practice owners contract with to handle non-clinical business functions, billing, HR, marketing, procurement, IT, while dentists retain clinical autonomy. Affiliation has grown steadily.

According to the ADA Health Policy Institute, about 16.1% of U.S. dentists were DSO-affiliated in 2024, and the rate of dentists affiliating with DSOs rose roughly 47% between 2017 and 2023. Estimates of DSO penetration vary widely across market-research firms, from around 10% of dentists to figures citing a much larger share of practices, because sources differ on whether they count dentists, practices, or market revenue, and on how they define affiliation. The concrete, verifiable anchor is the concentration among the largest players: the five largest DSOs support more than 5,600 practices, and the top 10 support roughly 7,800, with Heartland Dental alone supporting more than 1,900 affiliated offices across 39 states.

The Generational Divide

The single most important pattern in the ownership data is generational: the shift away from solo ownership is overwhelmingly driven by younger dentists making different choices than their predecessors.

DSO affiliation exceeds one in four among dentists less than 10 years out of school, roughly double the overall rate, and early-career dentists are far less likely to be in solo practice or to own than older cohorts. The drivers are structural: record student debt makes the capital and salaried stability of a DSO attractive out of school, while the traditional doctor-to-doctor practice sale, the path by which retiring owners once sold to younger dentists, has weakened as fewer young dentists seek immediate ownership. Later-career dentists, by contrast, are more likely to remain solo owners. The result is a profession splitting along generational lines in how it organizes itself.

Private Equity and Consolidation

Behind many of the largest DSOs is private equity, whose entry into dentistry has accelerated the pace of consolidation and reshaped practice valuations.

The ADA found the share of dentists and practices affiliated with private equity nearly doubled between 2015 and 2021. Consolidation has since remained brisk: DSOs were involved in a majority of dental practice acquisitions in recent years, and TUSK Practice Sales reported that 69% of DSOs expect to increase acquisition activity in 2026, though a limited supply of premium practices is creating a high-demand, low-supply market. Practices selling in 2026 have seen an average of five or more offers with final values well above initial bids, driven partly by the largest retirement-age cohort in the profession's history approaching transition. At the same time, several states have introduced legislation to limit corporate ownership and influence over clinical decisions, a countercurrent worth watching.

The Autonomy Debate

The rise of DSOs and corporate ownership is not a settled good or ill; it is a genuine debate within the profession, and honest coverage represents both sides.

Proponents point to concrete benefits: relief from administrative and business burdens (which dental school rarely trains dentists to handle), access to capital and technology, group purchasing that lowers supply costs, salaried stability, and better work-life balance, with roughly 45% of DSO dentists citing work-life balance as a reason to join. Critics and cautious independents raise equally real concerns: between about 29% and 37% of dentists cite loss of clinical autonomy as a reason to remain independent, and professional organizations have voiced worries about corporate influence over clinical decisions and profit-driven care models, concerns serious enough that several states have legislated on them. The reasonable reading is that both are true: DSOs deliver genuine operational advantages, and the autonomy concerns are legitimate. Which matters more depends on the individual dentist, the specific DSO, and the terms of the arrangement.
