Ask three people what a dental practice is worth — the broker, the buyer, and the seller — and you will get three numbers, each produced in good faith, none of them matching. Valuation confusion is not a failure of math. It is a failure of translation: brokers, buyers, and sellers speak different valuation languages, EBITDA is not the fixed number it appears to be, and add-backs are judgment calls rather than entitlements.
This article translates. The goal is not to make practice owners valuation experts; it is to make the numbers in their own deal legible before those numbers harden into terms.
Valuation is not a formula
The first correction to the common mental model: there is no formula. Two practices with identical revenue can be worth very different amounts, because buyers are not buying revenue — they are buying the risk-adjusted future of that revenue.
Risk, sustainability, and control drive pricing. A practice with stable staffing, documented systems, a defensible payor mix, and a transferable patient base earns a stronger multiple than a practice with the same collections and none of those qualities. And buyers price the downside before the upside: the first question in any buyer’s model is not “how good could this get?” but “how bad could this get, and would I survive it?”
Sellers who understand that ordering negotiate differently — and prepare differently.
What EBITDA actually means in dental deals
EBITDA — earnings before interest, taxes, depreciation, and amortization — is the standard currency of practice valuation. It is also the most misunderstood number in the deal.
EBITDA is a starting point, not a final value. In dental transactions, the number is heavily adjusted before it means anything: owner compensation is normalized to market rate, personal expenses are stripped out, one-time items are removed, and the result — adjusted EBITDA — is the number multiples actually get applied to.
That adjustment process is where deals are made and broken, because every adjustment is an argument, and the two sides of the table have opposite incentives about how each argument should resolve.
Add-backs: the judgment calls
Add-backs are adjustments that normalize earnings — intended to show what the practice earns under buyer-run economics, with the seller’s personal financial choices removed. The concept is legitimate. The application is where sellers get into trouble, because add-backs are routinely overstated, and buyers know it.
A useful way to think about which add-backs survive:
Generally accepted: normalizing owner compensation to market rate, documented one-time expenses, documented practice upgrades, verifiable non-recurring items.
Commonly rejected: “one-time” expenses that recur annually, discretionary bonuses recharacterized as extraordinary, unsubstantiated upgrades, and any adjustment whose support is a verbal explanation.
The pattern: documentation survives, narrative does not.
Why buyers discount add-backs
Buyers discount add-backs for a structural reason, not a temperamental one: the buyer is the one assuming the risk that the adjusted number is wrong. Sustainability matters more than explanation, because the buyer must operate the practice on the real earnings, whatever they turn out to be.
There is also a credibility mechanism at work. Over-adjusted EBITDA does not just lose the contested adjustments — it re-prices the seller’s credibility across the entire deal. Buyers who catch one aggressive add-back assume there are others, and adjust their posture on everything from indemnity terms to escrow size. The cost of aggressive adjustment is paid practice-wide.
How buyers actually think about value
Three priorities organize most buyers’ models.
Risk first. Before growth, before synergies, before potential — what could go wrong, and what would it cost? Stability over projections. A history of consistent collections outweighs a projection of growth, however plausible the projection. Buyers have all been shown hockey sticks before. Control and scalability. Buyers pay more for practices they can run their way — documented systems, transferable relationships, staff that stays. A practice that only works the way the seller runs it is worth less to everyone except the seller.
The same EBITDA, different multiples
Multiples are not universal, and the buyer’s profile changes the price. As a general pattern in single-location dental transactions of the size most private owners sell: aggressive, high-risk-tolerance buyers — typically DSOs underwriting growth — pay in the higher bands, roughly 6–8x adjusted EBITDA; moderate buyers price in the middle, 5–7x; conservative private buyers underwriting stability price lower, 4–6x. Larger practices and multi-location groups trade above these bands, sometimes well above — which is exactly the point: size, buyer type, and earnings quality select the band before negotiation begins.
The same practice, the same adjusted EBITDA, can legitimately attract offers across that entire spread. Quality of earnings moves a practice within the bands; buyer type selects the band. This is why “what multiple did your friend get?” is the least useful question in practice valuation.
How structure changes the number
Two offers with the same headline price can differ by hundreds of thousands of dollars in real value, because structure is value.
Rollover equity versus cash: a portion of the price paid in buyer equity is a different asset than cash — less liquid, contingent on someone else’s performance, and governed by terms most sellers never fully read. Earn-outs versus guaranteed price: consideration contingent on future performance shifts risk back onto the seller, often under conditions the seller no longer controls. Employment obligations: a purchase price that requires three years of post-closing employment at below-market compensation is, in part, not a purchase price.
Sellers comparing offers on headline price alone are comparing the wrong numbers.
Common valuation myths
Three beliefs cost sellers real money.
“My broker says it’s worth X.” The broker’s estimate is a marketing number, designed to win the listing and attract offers. It is not a diligence-tested number, and buyers do not negotiate against it.
“Add-backs always get accepted.” They are negotiated, line by line, and the seller bears the burden of proof on each one.
“The highest multiple wins.” The highest multiple frequently comes with the most structure — rollover, earn-out, employment terms — and structure is where value quietly leaves the deal.
When valuation changes — and it does
Valuation is not an event; it is a process with three distinct stages, and the number rarely survives all three intact. The pre-LOI valuation is the optimistic one. Diligence produces the tested one. Buyer pushback — the retrade — produces the final one.
Retrades are common, adjustments shift risk toward sellers, and final economics often differ materially from the LOI. None of this is necessarily bad faith; it is how the process works when diligence finds what preparation did not fix. The practical lesson: the seller’s best defense against the third-stage number is the work done before the first-stage number — and strong representation in between.
How sellers should think about value
Three reframes, in order of importance.
Net proceeds, not headline price. After debt payoff, taxes, transaction costs, escrows, and structure, what arrives? That is the number that matters, and it is knowable in advance — sellers should model it before signing anything. Risk-adjusted outcomes. A guaranteed $2.5M and a structured $3M with an earn-out are not $500K apart; depending on the terms, they may not be apart at all. Post-closing obligations. Years of required employment and the scope of a non-compete are part of the price the seller pays. They belong in the comparison.
A worked example
Abstract principles land better with numbers. Consider a practice collecting $1.8M with reported earnings of $400K, presented with $150K of add-backs: $60K of above-market owner compensation, $40K of “one-time” marketing, $30K of personal vehicle and travel, and $20K of family payroll.
The seller’s adjusted EBITDA: $550K. At the broker’s suggested 6x, the practice is marketed at $3.3M.
Diligence then does its work. The owner compensation adjustment survives — it is documented and market-based. The vehicle, travel, and family payroll survive in part, with documentation, at $35K of the claimed $50K. The marketing spend turns out to recur every year in some form; the buyer allows $10K. Tested adjusted EBITDA: $505K. The buyer — a private buyer underwriting stability — prices at 5x: $2.525M.
The seller’s mental anchor and the deliverable offer are now nearly $800K apart, and every conversation that follows happens in the shadow of that gap. Note what created it: not bad faith on either side, but optimistic adjustments meeting tested ones, and one multiple band meeting another. A seller who had run this same math conservatively before going to market would have anchored at a defensible number — and very likely closed at it.
Then the structure question: that $2.525M arrives as cash at closing. A competing DSO offer of “6.5x” — $3.28M on the same tested EBITDA — might deliver $2.1M in cash, $650K in rollover equity, and $530K in an earn-out contingent on two years of performance under DSO management. Which offer is higher? That is precisely the kind of question that should be answered on paper, before signing, with counsel — not discovered at closing.
Where legal counsel fits
Valuation looks like an accounting exercise, but its consequences are legal: the adjusted EBITDA becomes the purchase price, the purchase price becomes the agreement, and the agreement allocates every risk the valuation argued about. Counsel’s role is to translate economics into legal risk, push back on unjustified discounts during diligence, and preserve the seller’s leverage before the LOI locks the framework — which is why involving counsel at the LOI stage, rather than after it, changes outcomes.
The takeaway
EBITDA is a starting point. Add-backs are arguments. Multiples are buyer-specific. Structure is value. Sellers who internalize those four sentences before going to market keep materially more of their practice’s value than sellers who learn them during diligence.
