How to Sell a Dental Practice: The Complete Guide
Most dentists sell a practice once. The buyer across the table has done it 200 times. That asymmetry — not the multiple, not the market, not the timing — is where value leaks out of a deal. It’s why offers get repriced between the letter of intent and closing, why add-backs get rejected in diligence, and why sellers accept terms they didn’t have to.
I spent years on the buyer’s side of these deals, building and running the M&A team at one of the country’s largest DSOs. This guide is the process as the buyer sees it, because once you understand how the other side of the table works, most of the expensive surprises stop being surprises.
It covers the whole arc: when to start, what your practice is actually worth, who the buyers are, how the process runs month by month, how deals are structured, and where sellers lose money they didn’t have to lose.
Start Before You're Ready
The best exits start one to three years before the owner plans to sell. Not because the process takes that long (it doesn’t), but because almost everything that increases what a buyer will pay takes time to show up in your financials.
Buyers pay for the practice your last twelve to twenty-four months of numbers describe. If you decide to sell in March and call a broker in April, the practice being priced is the one you ran over the past two years, including the year you coasted, the associate who left, the fees you never renegotiated. None of that is fixable in the sixty days before going to market.
Starting early means you can make changes while they still matter: cleaning up the P&L so a buyer can read it, addressing the operational issues a diligence team will find anyway, and making the growth investments that a buyer will pay for rather than the ones they’ll ignore. It also means you’re never negotiating under pressure. Buyers can tell the difference between an owner who chose to sell and one who has to.
If you’re eighteen months out, you’re not early. You’re on time.
What Your Practice Is Actually Worth
Here is the single most important mental shift for a seller: buyers don’t price your collections. They price your earnings.
The rules of thumb you’ve heard, a percentage of collections or the multiple somebody’s classmate got, describe a market that no longer exists for most practices. Sophisticated buyers, and nearly all DSOs, value practices on EBITDA: earnings before interest, taxes, depreciation, and amortization. In plain terms, the cash the practice generates after paying everyone, including a market-rate dentist to do the clinical work you do.
That last clause matters more than any other sentence in this section. If you collect $1.5M and take home $500K, your EBITDA is not $500K, because the buyer has to pay someone to produce the dentistry you produce. What’s left after a market-rate replacement wage is the number that gets multiplied.
Two consequences follow:
Add-backs are where valuation is really negotiated. Your P&L includes expenses a new owner won’t carry: personal vehicles, family members on payroll, one-time equipment purchases, above-market rent you pay to your own building entity. Adding these back increases EBITDA, and every dollar of legitimate add-back is worth a multiple of itself at closing. But buyers don’t accept add-backs on your say-so; their diligence teams exist partly to reject the ones that don’t survive scrutiny. Documented, defensible add-backs get paid. Optimistic ones get crossed out, and a schedule full of optimistic ones makes the buyer distrust the legitimate ones too.
The number that matters is the one that survives diligence. Any buyer can put a big number in a letter of intent. What you’ll actually be paid is determined by what their quality-of-earnings review confirms months later. This is why the deals that close at their original price are almost always the ones where the seller’s numbers were prepared to buyer standards before going to market, not cleaned up in a panic during diligence.
This is also why we don’t quote multiples in articles, and why you should be skeptical of anyone who quotes one before understanding your practice. A multiple without a defensible EBITDA underneath it is a marketing number, not a valuation.
Know Your Buyers
Practices today sell into a more varied buyer pool than a generation ago, and the right buyer depends on what you want, not just the headline price.
DSOs and group platforms. Dental support organizations, most backed by private equity, are the most active acquirers of practices with strong earnings, especially multi-location groups and practices collecting above roughly a million dollars. They bring structured processes, professional diligence teams, and deal structures that usually include equity alongside cash. Selling to a DSO is neither the horror story nor the windfall it’s often portrayed as; it’s a specific kind of transaction with specific trade-offs, and the terms vary enormously between organizations. The difference between a good DSO deal and a bad one is in the documents, not the pitch.
Private buyers. An individual dentist buying your practice, typically bank-financed. Often the cleanest transaction for smaller practices: more likely to be all cash at close, no equity to evaluate, no integration into a larger organization. The constraint is financing: an individual’s bank loan caps out well below what earnings-based buyers will pay for a strong practice.
Associates. Selling to the associate already in your practice can be the smoothest transition for patients and staff, and the hardest deal to price honestly, because neither side wants the negotiation to damage the relationship. Associate deals benefit most from outside representation, precisely because the parties know each other too well.
Which buyer is right depends on your practice’s size, your timeline, and what you want your working life to look like afterward. A competitive process, where multiple qualified buyers know they’re competing, is how you find out what each will really pay, rather than what the first one offers.
The Process, Month by Month
Every deal is different, but a well-run sale follows a recognizable arc. From engagement to closing, most transactions run six to twelve months. Here’s the shape:
Months 1–2: Preparation. Financials are organized and normalized, the add-back schedule is built and documented, and the practice’s story is assembled into the materials buyers will evaluate: at minimum a confidential summary; for larger practices, a full databook. This stage determines how the rest of the process goes. Buyers price confidence; disorganized materials read as risk and get priced accordingly.
Months 2–4: Going to market. Qualified buyers are approached confidentially. Confidentiality is a process, not a hope. Buyers sign NDAs before learning identifying details. Your staff, patients, and competitors should not know your practice is for sale, and a properly run process keeps it that way until you choose otherwise.
Months 3–5: Offers and the letter of intent. Interested buyers submit offers; the strongest are negotiated against each other; you select one and sign a letter of intent. Understand what an LOI is: mostly non-binding on price and terms, but binding on exclusivity: once signed, you typically stop talking to other buyers. That makes the moment before signing your point of maximum leverage. Terms you don’t negotiate into the LOI rarely improve afterward.
Months 4–7: Diligence. The buyer’s team verifies everything: financials, payer mix, compliance, staff agreements, the lease. This is where prepared sellers coast and unprepared sellers suffer. It is also where repricing happens. When diligence finds gaps between what was represented and what’s real, the buyer returns with a lower number, and by then your alternatives have moved on. The defense is everything in this guide’s first two sections: start early, prepare to buyer standards.
Months 6–9: Documentation and closing. Purchase agreements, assignment of the lease, employment or transition agreements for you, and the closing statement that turns the headline price into actual proceeds. The unglamorous lines — working capital adjustments, accounts receivable treatment, proration of expenses — are where meaningful money moves at the very end. Read them, or retain people who do.
After closing. Most deals include a transition period; DSO deals usually include a multi-year clinical commitment. What your day looks like on the other side is a term you negotiate, not a footnote you discover.
How Deals Are Structured
The headline number is not what you receive at closing. Almost every substantial deal splits consideration into parts, and the split matters as much as the total.
Cash at close is exactly that: the portion wired on closing day. Holdbacks are amounts retained by the buyer for a period after closing, released when conditions are met. Earnouts tie part of the price to the practice’s future performance: you get paid if targets are hit, and the fine print defines whether those targets are realistic. Rollover equity, standard in DSO transactions, converts part of your price into ownership in the buyer’s organization, the “second bite of the apple” you’ll hear pitched, referring to the potential payout when that organization itself is later sold.
None of these structures is inherently good or bad. Rollover equity in a well-run organization that later sells can genuinely outperform the cash it replaced; equity in the wrong organization can be worth nothing, with conditions attached that nobody read closely. An earnout with achievable targets is deferred payment; one with aggressive targets is a discount wearing a disguise.
The evaluation is the same in every case: understand exactly what conditions attach to every non-cash dollar, and price the deal on the cash and the terms, not the press-release total.
The Team, and the Mistakes
Three professionals earn their fees in a practice sale: a dental-specific CPA (tax structure decisions such as asset versus stock sale and allocation often move more money than any negotiation), a healthcare transaction attorney (the purchase agreement is where the pitch becomes enforceable terms), and an M&A advisor or broker whose job is running the competitive process and negotiating from experience against buyers who do this constantly.
On that last one, an honest note, since I am one: not every practice needs representation. A small practice selling to a known associate at a bank-appraised price may do fine with just the CPA and attorney. Where representation earns multiples of its fee is where the asymmetry is largest: earnings-based valuations, DSO and private equity buyers, competitive processes, and structured deals with equity and earnouts. An unsolicited DSO offer is the clearest case of all: it isn’t a valuation, it’s an anchor, set by a buyer who knows exactly what your practice is worth to them and is betting you don’t.
The mistakes we see repeatedly, compressed: waiting until burnout to start, so the financials show a declining practice; negotiating the multiple while ignoring the structure; taking the first offer to avoid a process; treating the LOI as a formality; leaving add-backs undocumented; letting confidentiality slip to staff mid-process; and skipping specialist advisors to save fees on the largest transaction of their lives.
Every one of them is avoidable with time. Which is the real argument for starting early: not urgency, but options.
What to Do Next
If selling is somewhere on your horizon, even years out, the sequence is simple: find out what your practice is worth now, understand what’s driving that number, and make the improvements while there’s still time for them to pay.
That first step is exactly what we do. Ascend Strategic Partners offers a free, confidential practice valuation, reviewed personally by our founder, built the way a buyer would build it, with no obligation and no pitch. Most owners who request one aren’t ready to sell. That’s the right time to ask.
