Buy vs. Start a Dental Practice in 2026: The Full Comparison

Two doors, one check. Starting a practice from scratch takes $500,000 to $750,000 in total capital, according to Scott Leune's 2025 startup cost breakdown, and buying an existing one runs about the same $500,000 to $750,000, per Curve Dental's acquisition cost analysis. The price tags are effectively identical. What separates them is that one door opens onto a full schedule and a payroll that already covers itself, and the other opens onto an empty operatory, a marketing budget, and eighteen months of you paying the practice instead of the practice paying you.

Our view, and plenty of owners will fight us on it: in 2026, the startup is the wrong default. Unless you can name the intersection, the payer mix, and the specific households that will fill your chairs, buying is the better deal, and the gap is not close. The counterargument is real. Startup buyers pay zero goodwill, design the plumbing themselves, sign their own PPO contracts, and own a modern asset with nothing inherited. We've heard it and we still wouldn't take the trade. Goodwill isn't waste. Goodwill is prepaid ramp, and ramp is the single most expensive thing in dentistry.

Both Doors Cost About $650,000. Only One Comes With a Schedule

Notice what the startup number is actually made of. Clinical equipment runs $200,000 to $350,000, which is only 40 to 50% of total startup capital in Leune's breakdown. The other half is buildout, permits, IT, working capital, and the money you burn keeping the lights on while the phone stays quiet. Dentists price the chairs and the CBCT machine to the dollar. Then they treat the ramp as a mood.

On the acquisition side, the pricing convention is public: practices generally sell for 65 to 72% of the prior year's gross receipts, with some ranges quoted as high as 85%, per Curve Dental. That percentage is what the market charges you for skipping the ramp. Whether it's a bargain depends entirely on what the ramp would have cost you, and almost nobody runs that comparison honestly.

So let's run it.

Year One Swings $287,548, and That's With a Bad Transition

Assume the same capital stack on both sides: 100% financing, ten-year term, 8.5% interest, which is ordinary practice lending as of this year.

Start from scratch at $650,000 financed. The monthly payment is $8,059, so annual debt service is $96,708. A strong year one does $30,000 a month in collections, or $360,000. Your operating costs do not scale down to match: rent on a full-size suite, two to three staff, supplies, and a real marketing spend land around $420,000. That's an operating loss of $60,000 before a penny of debt service. Add the loan and the first-year cash gap is $156,708, which you fund out of the working capital line you borrowed. You draw nothing.

Now buy. Take a general practice collecting $900,000. At 70% of prior-year receipts, the middle of the published range, the price is $630,000. Borrow that plus $70,000 of working capital and your payment is $8,680 a month, or $104,160 a year.

Underwrite a bad transition, not a good one. Say you lose 15% of collections in the first twelve months to seller attrition and staff turnover, taking you to $765,000. Overhead does not fall proportionally, because rent and staff are sticky, so call it $530,000 instead of the $558,000 a clean 62% would predict. Pre-debt cash flow is $235,000. After debt service you take home $130,840 in year one.

That's a $287,548 swing in the first twelve months between the two doors. And it understates the damage, because the startup dentist also forgoes a salary. The median annual wage for dentists was $176,110 in May 2025, per the U.S. Bureau of Labor Statistics. Count that and the true year-one cost of building from scratch is $332,818 in cash burned and income forgone.

Three Years In, the Startup Is Still Down $573,144

Startup defenders will say the first year is supposed to hurt. Fine. Give the startup a strong ramp: $600,000 in year two at 80% overhead, which is $120,000 pre-debt and $23,292 after the loan. Year three hits $850,000 with overhead down to 69%, so $263,500 pre-debt and $166,792 after debt. Three-year cumulative owner cash: $33,376.

The acquisition recovers to full collections in year two and holds. Three-year cumulative owner cash: $606,520. The gap is $573,144.

The startup isn't cheaper. It's a $573,144 loan you make to your future self at zero interest, with no collateral and no guarantee the borrower ever shows up.

That number has to be earned back somewhere, and the honest case for the startup is that it gets earned back in years four through ten through better overhead, better payer mix, and a higher exit. Sometimes it is. But you need a six-year advantage of roughly $95,000 a year just to draw even, and you need to survive the first three years to collect it.

What Most Owners Get Wrong: They Underwrite the Build and Guess at the Ramp

The specific mistake: dentists two to six years out of school build a startup pro forma with the construction budget accurate to the dollar and the collections curve pulled out of the air. We see it in every plan that opens with a line-item equipment quote and closes with "conservatively, $75,000 a month by month eighteen."

The reason is structural. The people helping you build are equipment reps, contractors, and lenders whose involvement ends the day the loan funds. Nobody in that room is paid based on whether your hygiene column is full in month nine. The broker on the acquisition side has the opposite problem, an incentive to inflate, but at least the thing they're selling has a verifiable history: tax returns, production reports, recall lists, an aging schedule you can audit.

The second mistake is emotional, and it's the expensive one. "I'm not paying $400,000 for somebody else's patients" sounds like discipline. It's the most expensive sentence in dentistry. You're not buying patients. You're buying a phone that already rings, staff who already know where the instruments are, and a hygiene schedule that pays your note on day one. If you decline to buy that, you build it yourself and pay retail.

Fewer Individual Buyers, Same Wave of Sellers

Here's the part that should shape your timing. Only 72.5% of U.S. dentists were private practice owners in 2023, down from 84.7% in 2005, according to the ADA Health Policy Institute. Meanwhile 13% of dentists were DSO-affiliated in 2022, up from 10.4% in 2019 and 8.8% in 2017, and 27% of dentists five or fewer years out of school were DSO-affiliated, per ADA News.

Read that as a market, not a trend piece. The pool of individual dentists willing to sign a $700,000 personal guarantee is thinning while retirements keep coming. On the demand side, dentist employment is projected to grow 6% from 2025 to 2035, per the BLS, so the patients aren't going anywhere. If you're one of the shrinking number of people prepared to own, you're bidding against corporate buyers with a hurdle rate and a legal department, not against ten hungry associates. Corporate buyers pass on a lot: sub-$700,000 collections, rural, single-doctor, aging equipment, messy PPO contracts. That's where individual buyers get paid.

Supply is there. The Dental Signal Practice Market Index, built from dental practice broker listings, currently tracks 925 practices listed for sale. Among listings that disclose collections, the median is $957,588, with the middle half between $650,000 and $1,500,000 (n=753). For general practices specifically, the median is $946,000 (n=644). Those are asking-side figures, the practices choosing to sell, not a picture of all practices. But they tell you what the shopping aisle looks like, and the aisle is not empty.

Five Chairs and $200,000 a Chair: How to Read a Listing

Two numbers from the same dataset will do more for your due diligence than any valuation formula. The median listed practice has 5 operatories, with the middle half between 4 and 7 (n=754). And median collections per operatory among listings is $200,000, with the middle half between $146,875 and $268,708 (n=643).

Use them as a tripwire. A five-chair practice collecting $700,000 is running $140,000 per operatory, in the bottom quarter of what's on the market. That's either a seller who has been coasting for five years with unfilled hygiene and a dead recall list, which is the best acquisition in dentistry, or it's a practice in a market that cannot support five chairs, which is the worst. The tax returns won't tell you which. The recall report, the new-patient count, and a drive past the building at 10am on a Tuesday will.

Run the same test on your startup plan. If your pro forma has four operatories reaching $1.1 million by year three, you're penciling in $275,000 per chair, above the upper quartile of the practices currently for sale, from a standing start, in a market you don't yet serve. We'd drop that plan. Not revise it. Drop it.

When We'd Still Build From Scratch

The startup wins in a narrow, real set of conditions, and if you're in them, build.

• You already have the patients. You've been an associate in that zip code for three years, you have a non-compete you can work around legally, and a measurable share of your schedule would follow you. This is the only case where you effectively buy goodwill at zero cost.
• There is nothing to buy. You've watched your target market for twelve months and the only listings are $2.3 million multi-doctor practices priced for corporate buyers, or they're 40 minutes past where your family will live.
• Rooftops are outrunning chairs. New residential construction, a corporate campus, a hospital expansion, and a dentist-to-population ratio that hasn't caught up.
• Your model doesn't exist locally. Fee-for-service only, sleep, sedation, or a specialty referral base you've already built. You can't buy a PPO mill and convert it for less than the cost of building clean.

If you're in none of those four, you're not choosing a startup. You're choosing to pay $573,144 for control over the cabinetry.

What Would Change Our Mind

Two things we're watching. First, listing prices. If DSO and private-equity bidding pushes the multiple on $800,000 to $1.2 million general practices toward the 85% end of the published range, the acquisition advantage compresses fast and the startup math starts working for ordinary buyers, not just the four cases above. We're tracking the spread between listed collections and the asking side of the market each quarter for exactly that reason. Second, ramp speed. If the startups we see reaching $60,000 a month by month twelve turn out to be repeatable rather than exceptional, our three-year gap shrinks by more than half and this argument changes. We don't believe it yet. Show us twenty of them and we'll say so.

Call Two Brokers Before You Call the Equipment Rep

This week, get on the mailing list of every broker covering a 45-minute radius and ask for the last twelve months of sold listings, not just active ones. Pull your own year-one startup pro forma and rewrite the collections line as $30,000 a month for twelve months, then see if the deal still funds. Then take the three most plausible acquisition targets and divide collections by operatory count to find the one running under $175,000 a chair with a recall list nobody has called. That's your deal, and it will not be listed for long.

If you're weighing a specific practice right now, put the asking price next to its collections, overhead, and chair count before you get emotionally attached to it. Our free valuation calculator will show you what the numbers say a practice is worth and what debt service it can actually carry, so you can run your own numbers before the broker's spreadsheet runs them for you.
