The Rise of DSOs: What Dental Service Organizations Mean for B2B Sales

1. What Is a DSO?

A Dental Service Organization (DSO) is a company that provides business management and administrative support to dental practices. The dentist still handles clinical decisions and patient care, but the DSO manages everything else: billing, insurance processing, hiring, marketing, procurement, IT, compliance, and real estate.

Think of it like a franchise model, except the DSO typically owns or has an equity stake in the practices. Some DSOs acquire existing practices (the "roll-up" model), while others build new locations from scratch ("de novo").

The appeal for dentists is straightforward: they can focus on dentistry instead of running a small business. The DSO handles payroll, manages the lease, negotiates supply contracts, and runs the marketing. In exchange, the DSO takes a share of the revenue.

2. The Largest DSOs in the US

Over 300 DSOs operate in the United States. The market is dominated by a handful of large players:

Heartland Dental alone added 37 new practices in the past year (25 acquisitions and 12 de novo locations). The top 10 DSOs collectively manage over 5,000 locations. About 200 DSO transactions (acquisitions) were recorded in 2024.

3. Market Size and Growth

The US DSO market is on an aggressive growth trajectory:

• 2024: $37.9 billion
• 2026: ~$52 billion (estimated)
• 2035: $302 billion (projected, 6.87% CAGR)

Some market research firms project even more aggressive growth. Precedence Research estimates a 17.9% CAGR through 2034, while others project the global DSO market reaching $942 billion by 2035. The exact numbers depend on how broadly "DSO" is defined, but the direction is clear: consolidation is accelerating.

The roll-up/acquisition model accounts for about 41% of DSO market activity. The remaining 59% comes from de novo growth and organic expansion of existing DSO-affiliated practices.

4. Why DSOs Are Growing So Fast

New graduates prefer employment over ownership

58% of 2024 dental school graduates joined DSOs, up from just 22% in 2018. Student debt averages over $300,000 for dental school graduates. Rather than taking on more debt to buy or start a practice, new dentists are choosing the guaranteed salary and benefits of DSO employment.

Retiring dentists are selling to DSOs

15.5% of US dentists are 65 or older. Many are looking to exit, and DSOs offer an attractive buyout. Practice ownership has dropped from 85% in 2005 to 73% in 2023, and just 21% of dentists who graduated between 2016-2020 owned a practice within their first 5-9 years.

Economies of scale on procurement

DSOs negotiate bulk purchasing agreements with dental supply companies. Medical supplies and procurement is the largest DSO service segment at 27.8% of the market. A DSO with 500 locations gets dramatically better pricing than a solo practitioner.

Private equity is fueling acquisitions

Private equity firms see dental as an attractive investment: recession-resistant demand, fragmented market (ripe for roll-up), and predictable revenue. PE-backed DSOs are the most aggressive acquirers in the space.

5. Selling to DSOs vs. Independent Practices

If you sell products or services to dental practices, DSOs and independents require very different sales approaches:

The practical implication: you need to know whether a practice is independent or DSO-affiliated before you reach out. An email template written for a solo practitioner will fall flat with a DSO procurement team, and vice versa.

6. How to Identify DSO vs. Independent Practices

This is where dental practice contact data becomes valuable. A few ways to identify DSO-affiliated practices:

• Practice name patterns.DSOs often use standardized names (e.g., all Aspen Dental locations include "Aspen Dental" in the name). Look for repeated practice names across multiple cities.
• Website and branding. DSO practices often share the same website template, branding, or domain structure. Multiple locations with identical website designs are likely DSO-affiliated.
• NPI cross-referencing. The NPI registry lists the organization associated with each provider. Practices with Type 2 (organizational) NPIs linked to a parent entity are likely DSO-affiliated.
• Multi-location footprints.If the same entity owns practices in multiple states, it's almost certainly a DSO. Our database includes practice names that can be cross-referenced to identify multi-location groups.
