THE SELL-SIDE PLAYBOOK
How to Sell a Dental Practice
Selling a dental practice is a six-stage process — valuation, preparation, going to market, the letter of intent, due diligence, and close. Done well, it takes 3 to 5 years of preparation and 6 to 12 months to execute once the practice is listed.
The stage where most sellers lose money is not the negotiation. It is the due-diligence window after the letter of intent is signed, when the buyer's Quality of Earnings team re-prices the deal. This guide walks the full process and shows you where the value leaks — and how to defend it.
THE PROCESS
The Six Stages of a Dental Practice Sale
STAGE 1
Value the practice
Convert Seller's Discretionary Earnings into normalized EBITDA by resetting owner pay to a market associate rate, then apply the multiple for your size and buyer type. Platform-scale practices ($3M–$5M+ EBITDA) command 9–11×; add-ons run 5–8×. Run the valuation calculator →
STAGE 2
Prepare (12 months–5 years)
Fix the value drivers a buyer prices — hygiene mix, case acceptance, AR, owner dependency, clinical-coding compliance — and build a defensible data room. Institutional buyers audit 5 years of practice-management data, so improvements must be real and trailing, not transaction-motivated. See a de novo build $2.2M–$2.6M of value from zero →
STAGE 3
Run a sell-side QoE
Audit yourself the way the buyer will — 12 to 24 months ahead. A sell-side Quality of Earnings costs roughly $30K–$60K and can preserve hundreds of thousands in enterprise value by finding Phantom EBITDA before the buyer does.
STAGE 4
Go to market & sign the LOI
Engage a broker or approach DSO/PE buyers directly. The letter of intent states a price and grants the buyer a 60–120 day exclusivity window — but the LOI number is not the final number.
STAGE 5
Survive due diligence
During exclusivity, the buyer's QoE team re-prices everything. This is where 85% of lower-middle-market deals get re-traded downward (SRS Acquiom, 2025). Defend your EBITDA with documented add-backs and a clean compliance record.
STAGE 6
Close — know your real proceeds
Cash at close from a DSO is often only 40–60% of the headline, with the rest in earnout and rollover equity, plus a 15–20% escrow holdback for 24–36 months. Understand your realized value, not the stated multiple.
HOW LONG IT TAKES
Dental Practice Sale Timeline
| Stage | What Happens | Typical Duration |
|---|---|---|
| Preparation | Fix value drivers, build data room, sell-side QoE | 12–18 months (individual buyer) · 3–5 years (institutional) |
| Go to market | Broker engagement or direct outreach to DSO/PE | 1–3 months |
| Letter of intent | Price + exclusivity negotiated and signed | 2–4 weeks |

WHERE SELLERS LOSE MONEY
The Re-Trade: What Happens After the Handshake
The most expensive misunderstanding in a dental practice sale is treating the letter of intent as the deal. It is not. The LOI is the buyer's option to spend 60 to 120 days re-pricing you. 85% of lower-middle-market deals face a post-LOI purchase-price adjustment (SRS Acquiom, 2025) — and almost all of them move down.
Here is the mechanism on a representative deal: a $3M-collections practice with $600K EBITDA signs an LOI at 7× — a $4.2M headline. During diligence, the Quality of Earnings team disallows enough add-backs to drop EBITDA to $500K (a $700K re-trade at the multiple), a working-capital peg removes another $100K, and a 10% escrow holds back $350K. The seller walks with roughly $3.15M — about $1.05M evaporated between the handshake and the wire. Only about 15% of sellers avoid the re-trade — the ones who ran a forensic audit first.
The asymmetry is the whole problem: a buyer spends $50K–$200K+ dissecting your practice while the average seller spends $0 defending it. Closing that gap before the LOI is the highest-leverage move a seller can make. See the full breakdown in The LOI Is Not the Deal and Dental Practice Exit Strategy Planning.

FREQUENTLY ASKED QUESTIONS
Selling a Dental Practice FAQ
How long does it take to sell a dental practice?
Once a practice is listed, the average sale takes 6 to 12 months to close. The letter of intent grants the buyer a 60 to 120 day exclusivity window (typically 90 days) for due diligence, followed by 30 to 60 days to close. The longer horizon is preparation: an owner selling to an individual buyer should prepare 12 to 18 months ahead, while a practice positioning for a DSO or private-equity buyer needs 3 to 5 years, because institutional buyers audit 3 years of financials and 5 years of practice-management data.
How do I sell my dental practice to a DSO?
DSO and private-equity buyers screen for a specific profile: roughly $850,000 or more in collections ($1M+ preferred), four or more operatories, an owner willing to stay 2 or more years post-sale, and a defensible payer mix. The headline offer is rarely all cash — immediate cash at close is often only 40 to 60 percent of the stated valuation, with the remainder in an earnout (paid only if the practice holds its numbers) and rollover equity. The single biggest lever on your final number is whether your EBITDA survives the buyer's Quality of Earnings audit.
Do I need a broker to sell my dental practice?
A broker can run the marketing and process, and typical fees run 6 to 12 percent of deal value. But understand the incentive: a broker is paid a contingent fee to close the deal, not to fight the buyer's post-LOI re-trade. When the Quality of Earnings team cuts the price on Day 61, the broker's interest is in salvaging a closing, not in defending your original number. That gap is what a sell-side forensic audit fills.
What is a letter of intent (LOI) in a dental practice sale?
A letter of intent is a mostly non-binding document stating the buyer's proposed price and structure that grants them an exclusive 60 to 120 day window to complete due diligence. The critical point: the LOI price is not the final price. During exclusivity, the buyer's Quality of Earnings team re-examines your financials, and 85 percent of lower-middle-market deals see a post-LOI price adjustment (SRS Acquiom, 2025) — almost always downward. Signing an LOI starts the clock on the re-trade.
How much of the sale price do I actually receive at closing?
Less than the headline, on two fronts. First, structure: a DSO's cash at close is frequently 40 to 60 percent of the stated valuation, with the rest in earnout and rollover equity. Second, the re-trade: a typical deal places 15 to 20 percent of the price in an escrow holdback for 24 to 36 months, and the QoE audit often cuts the number before close. In one representative composite, a $4.2M headline offer became about $3.15M realized — roughly $1.05M lost between the handshake and the wire. The sellers who keep the most are the ~15 percent who run their own forensic audit before the LOI.
What is the most common mistake when selling a dental practice?
Going to market without first auditing yourself the way the buyer will. Buy-side diligence is intense and well-funded; the average seller spends nothing defending their number. Because 85 percent of deals face a downward post-LOI adjustment, an owner who has not run a sell-side Quality of Earnings audit is negotiating blind against a team that has modeled every vulnerability in their data. The fix is a forensic audit 12 to 24 months before going to market.
Audit Yourself Before the Buyer Does
The sellers who keep the most are the ones who run the buyer's audit on themselves first. The free Defense Gap field guide shows you exactly what a Quality of Earnings team will flag — while you still have time to fix it.
