Dental Practice Exit Strategy: Start Planning 5 Years Out

Three years of coasting can cost a retiring owner more than $200,000 in earnings before anyone has even made an offer, and the offer itself gets written against those same slumping numbers. Nobody buys a practice. They buy the last 24 months of it.

Here's our position, and plenty of advisors will dislike it: the standard counsel to begin exit planning 15 or 20 years out is correct in theory and nearly useless in practice. Kevin Fine of Kaufman Rossin puts it plainly, saying he'd "rather have 15 or 20 years to plan the correct strategy... than three or five years" instead of arriving in "the fourth quarter with the clock winding down." He's right about the clock. But a 15-year horizon is a philosophy, not a plan, and almost nobody executes against it. The five-year window is different. Five years out, every decision you make is close enough to the sale to show up in the diligence file and far enough out to actually season. That's the window where the money moves, and most owners sleep through it.

Why Five Years Became the Real Deadline

The timeline shifted underneath everyone. According to the ADA Health Policy Institute, the average dentist retirement age rose to 68.7 in 2024, up from 64.7 in 2001, and the average career span stretched to 41.3 years from 37.8. Owners are working four more years than their predecessors did.

That sounds like more runway. It isn't. It means the actual exit date keeps sliding, and the planning date slides with it, because planning anchors to the exit rather than to the calendar. An owner who at 58 figured on selling at 64 now figures on 68, which makes everything feel early. Then the body or the spouse or the equipment cycle makes the decision in about 90 days, and the practice goes to market with whatever numbers it happened to have.

Five years is the shortest horizon that still lets you change the thing a buyer is buying. Two full fiscal years of clean post-change financials, plus the year you're in, plus a year to make the changes, plus a year of slack for the change that doesn't work. Anything shorter and you're decorating.

Coasting From $950,000 to $814,506

Run a practice collecting $950,000 at 62% overhead. That's $589,000 of overhead and $361,000 of owner earnings.

Split that overhead the way it actually behaves: roughly $380,000 of it is fixed (rent, core staff, insurance, the loan on the CBCT) and the remaining $209,000 moves with production at about 22% of collections.

Now the coast. The owner drops to four days, stops replacing the hygienist who left, quits taking the implant CE, and lets new patient flow slide. Collections fall 5% a year for three years, which lands at $814,506.

The problem is that the fixed $380,000 doesn't coast with you. At $814,506 in collections, variable costs fall to $179,191, total overhead is $559,191, and owner earnings land at $255,315.

That's $105,685 less a year than the starting point, off a collections decline of $135,494. Overhead as a percentage has quietly climbed to 69%.

Add up the three coasting years and the shortfall is $37,050, then $72,248, then $105,685. Total: $214,983 of earnings the owner simply didn't take.

Then the practice goes to market. A buyer underwrites what the buyer can see, and what they can see is a three-year slide with overhead climbing seven points. Every lender and every DSO analyst runs the same trend line. The $214,983 is the part you lost in cash. The part you lose in price doesn't show up on any statement, which is exactly why owners don't feel it happening.

Our view: the last five years are the highest-stakes years of ownership, and they're the years almost everyone treats as a victory lap.

What Most Owners Get Wrong: Treating the Exit as an Event

The mistake is specific and it has a demographic. It's the solo owner between 55 and 65 who has never sold a business, has a good accountant and no transition advisor, and believes the exit begins the day they call a broker.

Under that belief, everything before the call is "running the practice" and everything after is "selling the practice," and the two are separate activities. So the owner optimizes the first for personal cash flow and comfort: run the car through the practice, keep the spouse on payroll at $48,000 for bookkeeping, defer the operatory refresh, stay in every PPO because churn is annoying at this stage of life, stop recruiting an associate because training one sounds exhausting.

Every one of those is defensible on its own. Together, they build a practice that reads badly in diligence: depressed earnings, a staffing structure the buyer can't replicate, deferred capital expense the buyer will price in, a payer mix with no room to improve, and total dependence on an owner who's leaving. The owner then discovers that the add-backs they assumed would be accepted are negotiated line by line, and that "my accountant says the real number is higher" is not a persuasive argument to a lender's credit committee.

The exit isn't an event. It's the last five years of operating decisions, scored by someone who wasn't in the room when you made them.

Drop the Plan at Year Minus Five, Not Year Minus One

Payer mix is the single biggest lever most owners have in the window, and it's the one most commonly pulled too late or not at all.

Before you drop anything, run the Break-Even Retention Test: break-even retention equals net collections per visit under the plan divided by net collections per visit out of network. Say the plan nets you $118 a visit and your out-of-network net is $185. Break-even retention is 63.8%.

So you need to keep roughly 64 of every 100 of those patients for collections to hold flat. Keep more, leaving wins. Keep less, stay in and renegotiate. On 1,100 plan patients, that's 704 you have to hold.

Here's the timing part nobody tells you. Attrition from a plan drop is front-loaded and recovery takes 12 to 18 months. Do it at year minus one and your trailing twelve months show a hole: collections down, new patient counts choppy, hygiene reappointment soft. The buyer prices the hole, not the fix. Do it at year minus five and the buyer sees two clean years at the higher net per visit and a payer mix with fewer obvious problems.

We'd make the payer decision at year minus five or not at all. A plan drop in the final 18 months is a gift to the buyer: you absorb the attrition, they inherit the margin.

Five Operatories, and What a Buyer Sees in the Sixth

Capacity is the quiet one. In The Dental Signal Practice Market Index, built from 925 dental practice listings currently on the market, the median practice listed for sale has 5 operatories (n=754) and collects a median $957,588 (n=753), with collections per operatory running a median $200,000 (n=643). These describe the asking side of the market, not practices in general, but they tell you what a buyer is comparing you against when they tour your building.

Take that $950,000 practice and give it seven operatories, two of which are used for storage and a staff lunch table. That's $135,714 per operatory.

An owner reads that as headroom. A buyer reads it two ways at once: upside, yes, but also rent and fit-out they're paying for and you're not using. If the lease carries all seven rooms, the fixed cost is in your overhead every month regardless. Filling one of those rooms with two hygiene days at $1,100 a day adds about $114,400 a year in collections.

That's the kind of change that needs 24 months to look like a trend instead of a spike. Year minus five, you hire. Year minus three, it's normal. Year minus one, it's a sentence in the listing.

The Buyer Pool Is Younger, Richer in Debt, and Slower to Commit

Ownership keeps thinning. ADA Health Policy Institute data shows 72.5% of U.S. dentists were private practice owners in 2023, down from 84.7% in 2005. That's the headline most sellers panic about.

The nuance matters more. HPI's cohort analysis found that younger dentists still become owners, they just do it later: among 2006-10 graduates, 72% owned a practice 10 to 14 years out, rising to 81% at 15 to 19 years out. The buyers haven't disappeared. They arrive about five years later than they used to, carrying more student debt and more associate experience, which makes them pickier and better at reading a P&L.

Demand underneath it is steady. The Bureau of Labor Statistics projects dentist employment to grow 6% from 2025 to 2035, faster than the average occupation, with about 4,800 openings a year. There will be someone to sell to. There will also be a well-prepared practice three towns over competing for the same buyer, and 925 listings on the market at any given moment is a reminder that sellers are not scarce.

What Would Change Our Mind

If DSO acquisition appetite stays aggressive enough that buyers keep paying on forward potential rather than trailing performance, the coasting penalty shrinks and the five-year discipline matters less. We're watching two things: whether listing volume in the Practice Market Index keeps climbing as the 68.7-year-old retirement cohort hits the market in bulk, and whether the gap between what well-run and poorly-run practices of the same size can command keeps widening. If it widens, the five-year window is worth more than we've argued here, not less.

Do These Four Things This Week

Write down your intended exit year, then subtract five, and see whether that date has already passed. Pull your last three years of collections and overhead and plot the trend line a buyer will see, not the one you feel. Run the Break-Even Retention Test on your worst-paying plan and decide this quarter, not next year. Then book 60 minutes with a transition advisor who has closed deals in your state, before you need one.

If you want a starting number for what the practice is worth today rather than at the finish line, run your own numbers through our free valuation calculator. It takes collections, overhead and owner compensation and gives you a baseline you can re-run every year of the five-year window, which is the only way to know whether the work is moving the number or just filling the calendar.
