DSOs Are Copying Amazon's Playbook. Most Will Fail.

A licensed dentist costs $176,110 a year in median wages, and the U.S. is projected to add roughly 9,000 dentist openings a year through 2035, most of them just replacing retirements, according to the Bureau of Labor Statistics. That one pair of numbers is why most of the platforms currently paying six and seven times earnings for your practice will never earn back what they paid.

Here's our position, and plenty of owners will hate it: for a practice collecting under about $1.5 million, a DSO offer in 2026 is priced like a growth exit and delivered like a salaried job, and most owners who sign one will end up with less total cash than if they had sold to an associate on a note and kept working three more years. The multiple is real. The money behind the multiple is not, because the arithmetic that makes roll-ups work in retail and software does not survive contact with a profession that can't manufacture its own supply.

The Flywheel Needs a Marginal Cost Near Zero. Yours Is $176,110.

The Amazon playbook is not "get big." It's a specific sequence: buy share at a loss, drive per-unit cost toward zero as volume rises, use the cost gap to take more share, then monetize the installed base with higher-margin services later. Every step depends on marginal cost collapsing. The thousandth package costs less to ship than the hundredth. The millionth AWS instance costs less to run than the thousandth.

Dentistry inverts that. The marginal unit of production in a dental practice is a chairside hour delivered by a person who needed eight years of training and a state license. Adding the thousandth office does not make the thousandth dentist cheaper. It makes them more expensive, because now you are bidding against your own regional offices for the same scarce hire in the same metro. With employment growing just 6% across 161,400 jobs from 2025 to 2035, the supply curve does not bend, per BLS. Scale in dentistry buys you purchasing discounts on gloves and a slightly better payer contract. It does not buy you the thing Amazon bought, which is the right to be structurally cheaper than everyone else forever.

Platforms know this, which is why the pitch has quietly shifted from "we make your practice more efficient" to "we give you access to capital and a career path." That's a staffing agency with a balance sheet. It's a fine business. It is not worth what buyers are paying.

What the 16% Number Actually Tells You

As of 2024, 16% of U.S. dentists were DSO-affiliated, and solo and small-group ownership slid from 84.7% of dentists in 2005 to 72.5% in 2023, per ADA Health Policy Institute research. Most commentary reads that as a straight line to consolidation. Read the age split instead. More than 25% of dentists within ten years of graduation were DSO-affiliated in 2024, far above veteran dentists, in ADA HPI's analysis of about 200,000 practicing dentists.

That is not a demand story about patients preferring corporate dentistry. It's a supply story about new graduates carrying debt who want a paycheck on day one instead of a bank loan. The platforms are not winning the market. They are winning the entry point, and then losing those same dentists three to five years later when the associate decides they'd rather own. Every time that happens, the platform pays to recruit a replacement, eats the production dip, and calls it "normal turnover" in the operating report.

The capital behind it has been real. Private equity affiliation among U.S. dentists nearly doubled from 6.6% in 2015 to 12.8% in 2021, and PE dental transactions went from fewer than 20 a year between 2004 and 2015 to 96 in 2021, per Nasseh, LoSasso and Vujicic in Health Affairs. Specialist affiliation more than doubled. A fivefold jump in deal pace over six years is what a land grab looks like. It is also what the setup for a wave of failed second exits looks like, because the platforms that bought in 2019 through 2022 now have to sell to somebody at a higher multiple than they paid, in a higher interest rate environment, with the same dentist shortage they had on day one.

A $1.2 Million Practice, Line by Line, Through the Buyer's Model

Run the numbers the way a platform's finance team runs them, then run them again eighteen months later.

Take a general practice collecting $1.2 million, where the owner takes $420,000 a year in combined salary and profit. Operating expenses excluding the owner are therefore $780,000.

The buyer's first move is to normalize owner compensation down to market. Using the BLS median of $176,110 plus 15% for payroll taxes and benefits, the replacement dentist costs $202,527. Adjusted EBITDA becomes $217,473. That's 18.1% of collections, which is exactly the band that gets a practice a serious letter of intent.

At seven times, the offer is $1,522,311. The owner sees a seven-figure number and stops reading. Keep reading.

Post-close, the practice pays a management fee to the platform. At 6% of collections that's $72,000 a year, leaving $145,473.

Then the owner's earn-out ends and an employed associate takes the chair. Assume a 10% production drop, which is conservative when a 20-year relationship practice changes hands. Collections fall to $1,080,000, a $120,000 loss. At 30% variable cost on that production, the contribution hit is $84,000, and EBITDA lands at $61,473.

The buyer paid $1,522,311 for an asset now throwing off $61,473. That's 24.8 times earnings. Finance 55% of the purchase with debt at 10.5% and annual interest is $87,913, which is more than the practice now earns. The office is not underperforming. It is doing exactly what a dental practice does when the producer who built it leaves. The model was wrong, not the office.

Now the seller's side. If the deal requires three years of clinical work at $202,527 against the $420,000 you were taking, you are giving back $217,473 a year, or $652,419 over the earn-out. Net of that, the effective price for the practice is $869,892. You didn't get seven times. You got about four, paid partly by yourself.

We wouldn't take that deal at $1.2 million in collections. We'd take it at $3 million with two associates already producing and a non-owner-dependent hygiene column, because then the cash flow survives your departure and the multiple is attached to something real.

What Most Owners Get Wrong: Confusing the Multiple With the Price

The specific mistake, and it is overwhelmingly made by owners aged 55 to 65 who have never sold a business before, is negotiating the multiple and ignoring everything else in the document. They'll spend six weeks pushing a buyer from 6.2x to 6.8x, a difference of about $130,000 on the practice above, while signing an earn-out that costs them $652,419 and a rollover equity stake whose value depends entirely on a second sale that may never happen at a higher price.

Rollover equity is where this gets ugly. You're typically asked to keep 20% to 30% of your proceeds in platform stock, unvalued, illiquid, junior to the debt, and marked at whatever the sponsor says it's worth. If the platform's second exit comes in flat, that rollover returns your money with no gain after five years of inflation. If it comes in below the entry multiple, which is the live risk for anything bought at 2021 prices, it returns less. Our view: rollover equity should be treated as a zero in your planning, and if the deal doesn't work with that stake valued at nothing, the deal doesn't work.

The second mistake is smaller but more common. Owners compare the DSO offer to doing nothing. The right comparison is the DSO offer against a structured sale to an associate, where you carry a note at 8%, stay two days a week as an employed dentist with no management fee skimming 6% off the top, and keep the building.

The Platforms That Survive Won't Look Like Amazon At All

The survivors will look like franchise systems or like specialty groups with genuine clinical concentration. Franchising works because the capital risk sits with the local owner, who is also the producer, which solves the exact problem that kills the salaried model. Specialty groups work because oral surgery, endo and ortho have real referral network effects and procedure mixes where a strong clinician is genuinely more productive inside a group. Specialist PE affiliation more than doubled over the 2015 to 2021 window for a reason, per the Health Affairs analysis.

What will not survive is the general-dentistry platform with 40 offices in four states, a shared call center, and no answer to the question of who sits in the chair when the founding dentist's non-compete expires. Amazon could afford to lose money on every early order because the next order cost almost nothing. Your next crown costs a dentist, and the country makes about 9,000 of them a year, most just backfilling retirements.

Four Things To Do Before You Take the Next Platform Call

Pull your last twelve months of production by provider and calculate what percentage you personally generate. If it's over 60%, you are selling a job, not a business, and you should price it that way or spend two years fixing it first. Ask any buyer for the cash-on-cash return you'd receive in each of the next three years after the management fee and your reduced comp, in writing, and walk if they won't produce it. Value your rollover equity at zero and see whether the deal still clears your retirement number. And get a real market read on your practice before the first call, not after, because the buyer's normalized EBITDA is a negotiating position, not a fact.

If you're weighing an offer, or just want to know what your practice is actually worth before someone tells you, our valuation tool runs the same normalization a platform's finance team runs, including the owner-comp adjustment and the earn-out drag most letters of intent bury on page nine. Run your own numbers and see what the multiple really nets you.

We're watching two things that would change our call. One: whether early-career DSO affiliation, already above 25% for dentists within ten years of school, keeps climbing or flattens as those dentists hit year five and start buying. Two: whether any general-dentistry platform completes a second sale at a higher multiple than it paid in 2021. If both break the other way, the scale thesis is better than we think and we'll say so.
