US dentist universe, mapped
There are 202,536 professionally active dentists in the US. We map each practice and the owner who actually buys.
For practice management, imaging, billing, supply, marketing, and clear-aligner teams selling into dental. The front-desk number is rarely the buyer. The owner-dentist in the back office is.
The market, in three numbers
A long tail of owner-dentists. A growing DSO middle.
are not DSO-affiliated
Per the ADA Health Policy Institute, around 13 percent of practising dentists were DSO-affiliated in 2022. The other 87 percent work in solo or small group practices. The owner-dentist is still the buyer.
are active general dentists
Of the 202,536 active dentists, roughly 155,000 are general dentists. The rest are split across the nine recognized specialties, led by oral surgery, orthodontics, and pediatric dentistry.
active practice locations
The site count moves with the dentist count, plus or minus the satellite-office math. Around 178,000 active dental practice addresses, give or take how you treat group locations and partnerships.

Methodology
Why our dentist count moves and the published estimates do not.
The headline figures you usually see, 202,536 dentists or roughly 178,000 practices, come from once-a-year supply reports. They are accurate the day they ship and stale by month two. We work practice by practice and refresh.
How the 202,536 figure is built
- Start with the ADA Health Policy Institute supply universe. The HPI publishes the count of professionally active US dentists by state, specialty, and age band. Cross-referenced against the BLS Occupational Employment & Wage Statistics for 29-1021 Dentists, General.
- Resolve each dentist to a real operating practice. A solo dentist is one practice. A four-partner group is one practice with four chairs. A satellite office is a separate address. We map to the address because that is where the software, the chair, and the supply order live.
- Find the owner. Around 87 percent of practices are independent or small group. Most owner-dentists are the same person who signs the supply invoice and approves the imaging upgrade. We name them, with a verified email and a direct dial, the same way we do for every other long-tail vertical.
- Tag the DSO affiliation. Heartland, Aspen, Pacific Dental Services, Smile Brands, MB2 and the rest run on a shared services model. The decision-maker is at corporate, not at the chair. We mark these so a vendor selling into independents does not waste a quarter pitching a managed practice.
- Drop the dead pins. Retired dentists, closed practices, addresses absorbed into a DSO acquisition. The annual report keeps them on for a year. We do not.
If you want the source breakdown for a specific state, specialty, or DSO, ask. We do not hide the working.
By state
Where the dentists actually are.
The five largest states carry roughly 43 percent of US dentists. Per capita, the Northeast leads: Massachusetts, New Jersey, and Connecticut all run well above the national rate of 61 dentists per 100,000 residents.
| # | State | Active dentists | Per 100k residents |
|---|---|---|---|
| 1 | California | 32,500 | 83 |
| 2 | New York | 16,400 | 83 |
| 3 | Texas | 16,100 | 52 |
| 4 | Florida | 13,300 | 58 |
| 5 | Illinois | 9,600 | 77 |
| 6 | New Jersey | 8,200 | 88 |

The largest DSOs
The biggest dental support organizations, and how much of the market they hold.
DSO brochures are loud. The math is quiet. The ten organizations below together affiliate with under 8 percent of US dentists. The rest, more than 186,000 practising dentists, sit in solo and small group practices. That is the actual shape of the market.
| # | DSO | US locations | Notes |
|---|---|---|---|
| 1 | Heartland Dental | ~1,700 | KKR-backed. The largest US DSO by location count. Supported offices run on a shared services model with the owner-dentist retaining clinical autonomy. |
| 2 | Aspen Dental Management | ~1,100 | Leonard Green-backed retail dental model with a heavy advertising spend. Branded "Aspen Dental" storefronts across nearly every state. |
| 3 | Pacific Dental Services | ~970 | Founder-led, growing through de novo openings rather than acquisition. Brand co-locates with Costco and other retail anchors in parts of the country. |
| 4 | Smile Brands | ~750 | New Mountain Capital-backed. Operates under multiple regional brands including Bright Now Dental, Castle Dental, and Monarch Dental. |
| 5 | Dental Care Alliance | ~390 | Mubadala-backed. Multi-brand DSO with a heavy footprint in the Southeast and Mid-Atlantic. |
| 6 | MB2 Dental | ~750 | Partnership model where the owner-dentist retains equity. Charlesbank-backed. One of the fastest-growing affiliations in the market. |
| 7 | Affordable Care | ~430 | Operates Affordable Dentures & Implants and AffordableDentist.com. Berkshire Partners-backed. Heavy on full-arch and removables. |
| 8 | Western Dental | ~340 | New Mountain Capital-backed. Strong concentration in California, Arizona, Texas, and Nevada. Heavy Medicaid mix. |
| 9 | North American Dental Group | ~250 | Jacobs Holding-backed after the Abry acquisition. Multi-state DSO with a focus on quality affiliations rather than de novo speed. |
| 10 | Great Expressions Dental Centers | ~240 | Roark Capital-backed. Long history in the Midwest and Southeast. One of the older DSO platforms in the market. |
Counts marked "~" are approximate, drawn from each DSO's most recent public disclosures, the Group Dentistry Now top-DSO ranking, and our practice map. The order above is by US location count, not revenue. DSO-affiliated practices retain the dentist's name on the door and the licence on the wall; the buying decision for many vendor categories moves to corporate.
Our take
The DSO consolidation story is overcounted by the vendors who sell into DSOs.
We believe
If you sell into dentists and you only target the top DSOs, you are walking past 175,000 buyers.
The standard motion in dental SaaS is to chase the platform deal. Sign Heartland, sign Aspen, win the regional. We have watched a practice-management vendor work that motion for two years and then look at the math: the top ten DSOs combined affiliate with roughly 15,000 dentists. The other 187,000-odd are in solo and small group practices, where the buyer is the owner-dentist with their name on the door. The DSO TAM is real. It is also a fraction of the universe.
One of those owner-dentists called us last quarter. He runs a two-chair practice outside Cleveland. He had been on the same imaging software for eleven years. His sales rep had retired. The replacement rep called the front desk twice, did not get past reception, and stopped trying. He was actively looking for a new vendor and could not find one who could find him. That is the market most dental vendors are missing. Not because the dentists are hiding, but because the data tools are searching for "Heartland" instead of the LLC that pays the practice's lease.
Who buys this data
B2B vendors selling into 202,536 dentists.
This page is for the teams selling into dental practices, not the dentists themselves. The buyer for this dataset usually falls into one of these categories.
Practice management software
Dentrix, Eaglesoft, Curve, Open Dental, and the cloud challengers selling the upgrade off a server-room PMS. The buyer is the owner-dentist, not the office manager and not the DSO.
Dental imaging and X-ray
Carestream, Dexis, Planmeca, Vatech sales reps targeting the next cone-beam or intraoral upgrade cycle. The decision and the capex sign-off sit with the dentist who owns the practice.
Insurance billing and RCM
Revenue-cycle services, claims-clearinghouse vendors, and outsourced billing teams selling the cost-per-claim or percent-of-collections story to practices losing receivable days.
Dental supply distributors
Henry Schein, Patterson Dental, Benco field reps and the digital procurement challengers. The opportunity is to win the standing supply order at independent practices, not at the DSOs already locked in on a master agreement.
Dental marketing and SEO agencies
Agencies pitching new-patient acquisition, local SEO, paid social, and Google Business Profile management. Owner-dentists buy this themselves, usually after a slow Tuesday.
Dental staffing and clear aligners
Hygienist and associate staffing platforms (Cloud Dentistry, Onederful), plus clear-aligner vendors selling into general dentists who want to keep ortho cases in-house instead of referring them out.
If your motion is closer to outbound, the conversion path is the dentist email list built on this same universe. Adjacent slices: the email lists by medical specialty, and the broader /data index.
Plain-spoken
When the dentist dataset is the wrong fit.
Do not buy this if any of the following are true.
You only sell into the top DSOs. If your motion is one master agreement with Heartland and one with Pacific Dental, you do not need 202,536 records. You need two phone numbers and a long sales cycle. Save your budget.
You sell to patients, not practices. Tele-dentistry apps, direct-to-consumer aligner brands, dental insurance for end users: this is operator-side data, not consumer-side. Different shape, different licence.
You need clinical patient records. Radiograph archives, EHR-level treatment histories, HIPAA-covered patient PHI: those live inside the practice's PMS and never leave. We do not stand any of that up here.
You only sell to dental schools and academia. The 66 US dental schools and their faculty appointments are a separate, much smaller universe. The decision cycle is institutional, not operator.
The honest version
Why most dentist vendor data is wrong.
If you Google "how many dentists in the US," the top result is usually a press release citing the 202,536 professionally active dentists in the ADA Health Policy Institute supply report. That is the right number, and we cite it directly. It is also a count of people, not of buyers. The same dentist might own one practice or work as an associate at three. The same practice might have one owner-dentist and four hygienists. The headline figure does not draw that line. The buyer for your supply order, your imaging upgrade, or your PMS contract does.
The next problem is the DSO middle. Enterprise data tools index by company, so "Heartland Dental" looks like one customer with 1,700 locations. For some vendor categories, that is true. For most, it is not. Heartland's affiliated dentists sit in supported offices that retain the owner-dentist's name on the door, the local LLC, and a healthy chunk of the day-to-day vendor decision. A vendor who pitches Heartland corporate and ignores those 1,700 owner-dentists has done half the work and won a third of the meetings.
This is exactly the gap Orbital was built for. We map the universe of US small and mid-market businesses, find the owner of each one, and validate the contact before it reaches you. Nothing about that is dental-specific, which is why we can also map gas stations, HVAC contractors, med spas, restaurants, and auto dealers the same way. What is specific to dental is the layer on top: specialty (general, ortho, perio, oral surgery, paediatric, prosth, endo, public health, oral pathology, oral radiology), DSO affiliation, practice size, and whether the dentist runs one chair or twenty.
One more piece of context worth pricing in. ADA Health Policy Institute, BLS, IBISWorld, and Dental Economics all publish on this market. They are excellent and we cite them. They are also annual or quarterly. For a vendor doing outbound this quarter, the question is which practices are open this Monday, which owner-dentists are not on a DSO contract, and which numbers actually reach a human. That is the gap a practice-by-practice, owner-by-owner map closes.
Questions
Before you ask sales about the dental dataset.
How many dentists are there in the US?
There are 202,536 professionally active dentists in the United States, per the American Dental Association Health Policy Institute, 2024. That count includes general dentists and the nine recognized specialties. Around 155,000 of them are active general dentists. Orbital maps them against the population of US dental practices, refreshed monthly.
How is your count different from the ADA Health Policy Institute?
The ADA number is the authoritative count of licensed, professionally active dentists, and we cite it directly. The ADA does not maintain a public, owner-resolved practice directory with verified contact data. Orbital's count is the same headline number, resolved to the practice that employs each dentist, with the owner-dentist or office manager named per practice. The ADA tells you how many; we tell you which practice and who to call.
Are most dentists owned by DSOs now?
Not yet. The ADA Health Policy Institute puts DSO-affiliated dentists at around 13 percent of practising dentists in 2022, up from about 7.4 percent a decade earlier. The other 87 percent still work in solo or small group practices. The DSO story is real and growing, but the universe a vendor is selling into is still dominated by independent owner-dentists.
How many dental practices are there in the US?
Around 178,000 active dental practice locations, depending on how you count satellite offices and group practices. The ADA tracks dentists; IBISWorld and the BLS track establishments. The numbers diverge because a multi-location group practice is one business with several addresses. Orbital maps to the address, because that is where the chair, the software, and the supply order live.
Which state has the most dentists?
California has the most, with around 32,500 active dentists. New York is second at roughly 16,400, then Texas at 16,100, Florida at 13,300, and Illinois at 9,600. Per capita, the Northeast leads. Massachusetts and New Jersey have more dentists per 100,000 residents than most of the country. Rural states in the Mountain West sit at the bottom.
Who actually buys dentist data?
Vendors selling into dental practices. Practice management software (Dentrix, Eaglesoft, Curve, Open Dental and the cloud challengers). Dental imaging and X-ray vendors. Insurance billing and revenue-cycle services. Dental supply distributors. Dental marketing and SEO agencies. Staffing platforms for hygienists and associates. Clear-aligner and orthodontic vendors selling into general dentists. The common thread is they need the owner-dentist, not the publicly listed front-desk number.
Can I filter the dataset by state, specialty, or DSO?
Yes. Tell us the slice. State, metro, specialty, DSO affiliation, practice size, or any combination. We send the export filtered to that slice. The full universe is there if you want it. Most buyers do not.
Can I get a sample of the dentist owner data?
Yes. Tell us the state or specialty you want and we send a sample of around 100 verified owner-dentist records you can check against your own pipeline before anything changes hands. There is no charge for the sample.
