How to Sell a Dental Practice: A Step-by-Step Guide

I've guided dozens of dentists through practice sales, and the ones who get the best outcomes share one trait: they started planning 12-18 months before they wanted to close. The ones who call me saying "I want to be done by June" almost always leave money on the table.

Selling a dental practice is not like selling a house. You can't just list it, accept the highest bid, and hand over the keys. There are patients to transition, staff to retain, leases to negotiate, and regulatory hurdles that don't exist in other industries. Here's the step-by-step process I walk every seller through.

Step 1: Decide Your Timeline (12-18 Months Out)

The ideal timeline for a dental practice sale is 12-18 months from decision to close. That sounds like a long time, but here's what fills it:

• Months 1-3: Financial cleanup, lease negotiation, practice preparation
• Months 3-5: Valuation, broker selection, marketing materials
• Months 5-9: Confidential marketing, buyer meetings, LOI negotiation
• Months 9-13: Due diligence, purchase agreement, lender approval
• Months 13-18: Closing, transition period, patient handoff

Rushing this process is the single most expensive mistake I see. A practice that could sell for $1.2M with proper preparation might go for $850K because the seller needed out quickly and accepted the first offer.

Step 2: Choose the Right Broker (Dental-Specific vs Generalist)

This decision matters more than most sellers realize. A generalist business broker will value your practice on SDE or EBITDA, list it on BizBuySell, and wait for inbound interest. A dental-specific broker understands collections-based valuation, has relationships with DSOs, knows which banks do dental practice lending, and can identify red flags that general brokers miss entirely.

The two largest dental-specific brokers in the US are AFTCO (the oldest, founded in 1968, handling 300+ transitions annually) and Henry Schein Practice Transitions (leveraging their equipment and supply relationships for buyer access). Regional firms like Professional Practice Sales and McNor Group also have strong track records in specific markets.

Commission structures are typically 7-10% of the sale price, with some brokers charging a flat fee for smaller practices under $500K. The dental-specific brokers generally justify their fees by generating 15-25% higher sale prices than generalists, primarily because they run competitive processes with multiple qualified buyers rather than taking the first offer that comes in.

Step 3: Understand Your Valuation Options

Dental practice valuation isn't one-size-fits-all. The methodology depends on who's buying. I cover this in depth in my guide to dental practice valuation, but here's the summary:

Collections-based (60-85% of annual collections) is the standard for private buyer sales. A solo GP collecting $900K annually would expect offers in the $540K-$765K range from another dentist. The percentage depends on hygiene production, payer mix, active patient count, and facility condition.

SDE-based (1.5-2.5x SDE) is increasingly common as private equity influence pushes more sophisticated analysis into private sales. SDE adds back owner compensation, interest, depreciation, and discretionary expenses to get a true picture of owner earnings.

EBITDA-based (5-12x EBITDA) is the DSO standard. If your practice generates $500K+ in EBITDA or you have multiple locations, DSOs are realistic buyers and the math shifts dramatically in your favor.

Step 4: Private Buyer vs DSO Sale — The Real Trade-offs

This is the most consequential decision in your sale process, and it's not just about price.

Selling to a private buyer (another dentist) means a clean break. You typically stay for 30-90 days of transition, introduce the new dentist to patients, and walk away. The sale price is lower, but you get your life back. Most private sales are asset sales, which means favorable tax treatment for the buyer (they can depreciate the purchase price) and a simpler deal structure.

Selling to a DSOmeans a bigger check, but you're not done working. Most DSO deals require a 3-5 year employment agreement where you continue as the lead clinician. You'll typically receive 60-70% of the purchase price at closing and 30-40% as an earn-out tied to revenue retention or EBITDA targets. The upfront check is larger, but the golden handcuffs are real. I've had sellers tell me they felt like employees in their own practice after selling to a DSO.

The financial comparison can be stark. A practice collecting $1.5M with $400K SDE and $200K EBITDA might sell for $800K to a private buyer (2x SDE) or $1.2M-$2.0M to a DSO (6-10x EBITDA). But that DSO price comes with years of continued clinical commitment and earn-out risk.

Step 5: Prepare the Practice for Sale

Preparation is where most of the value creation happens. The practices that sell at the top of the range share these characteristics:

Hygiene production at 30-35% of total production. This is the single most important metric for transferability. Hygiene patients come back regardless of who owns the practice. If your hygiene department is at 20%, hire another hygienist and build it up before going to market. Every percentage point of hygiene production ratio translates directly to buyer confidence.

An associate on staff. Even a part-time associate working 2-3 days per week proves the practice can function without you. This is especially critical for DSO sales, where the buyer needs to know an associate model works in your patient base. Bringing on an associate 12 months before selling is one of the highest-ROI moves you can make.

A lease with 7+ years remaining.Buyers need lease certainty to secure financing, especially SBA loans. If your lease expires within 3 years, negotiate a renewal before going to market. I've seen deals fall apart because the landlord wanted to renegotiate at a 40% rent increase, which killed the buyer's cash flow projections.

Clean financials with no surprises. Three years of CPA-prepared financial statements, clear separation of personal and business expenses, and a well-organized chart of accounts. Surprises during due diligence kill deals or result in price reductions.

Step 6: The Transition Period (Patient Retention Is Everything)

Here's the number that keeps every dental practice buyer up at night: what percentage of patients will stay after the sale? Industry data shows that with a proper transition, 85-95% of patients stay. Without one, attrition can hit 30-40%.

A proper transition means:

• The selling dentist stays 30-90 days (longer for larger practices)
• Joint introductions — the selling dentist personally introduces the buyer to patients during appointments
• A letter from the selling dentist endorsing the new owner, mailed to all active patients
• Staff retention — the front desk and hygienists staying is often more important than the dentist staying
• No changes to systems, hours, or insurance participation for at least 6 months

The most successful transitions I've seen involve the buyer working alongside the seller for 60 days, gradually taking over the schedule. By the time the seller leaves, most patients have already met the new dentist at least once.

Step 7: Tax Considerations — Asset Sale vs Stock Sale

The tax structure of your sale can swing your after-tax proceeds by $100K+ on a $1M transaction. Most dental practice sales are structured as asset sales, which benefits the buyer (they depreciate the purchase price) but creates a more complex tax picture for you.

In an asset sale, the purchase price is allocated across several categories, each taxed differently:

• Equipment and supplies — taxed as ordinary income to the extent of prior depreciation (recapture), capital gains above that
• Practice goodwill (personal) — taxed at long-term capital gains rates (currently 20% federal + 3.8% NIIT for high earners)
• Enterprise goodwill — also capital gains, but the allocation between personal and enterprise goodwill matters for non-compete enforceability
• Non-compete agreement — taxed as ordinary income
• Consulting/transition services — taxed as ordinary income

The allocation negotiation is critical. Sellers want more allocated to goodwill (capital gains rates). Buyers want more allocated to equipment and non-compete (faster depreciation). Your CPA and attorney need to be involved early. I've seen sellers lose $80K+ in after-tax proceeds because they agreed to an unfavorable allocation without understanding the implications.

The Bottom Line

Selling a dental practice is a 12-18 month process that rewards preparation, patience, and professional guidance. The dentists who start planning early, choose dental-specific advisors, build their hygiene departments, and run a competitive process consistently achieve 20-30% higher sale prices than those who wing it. Your practice is likely the most valuable asset you own. Treat the sale with the same diligence you'd expect from a patient accepting a $50,000 treatment plan.
