Buying a Dental Practice: The Red Flags Hiding in Every ‘For Sale’ Listing

Here’s the uncomfortable truth about most dental practices for sale: the listing was engineered to hide the exact things that will bankrupt you. A polished broker packet, a fat “gross collections” number, and a smiling seller are not evidence of a good deal. They’re the wrapping paper. Your job is to open the box before you wire the money — not after.

On the Bulletproof Dental Practice podcast, Pete Boulden and Craig Spodak have spent years pulling apart deals with brokers, lenders, and owners who bought a “turnkey” practice that turned out to be a landmine. The pattern is brutally consistent. The red flags are always there. Most buyers just don’t know where to look — or they’re so emotionally sold on “being an owner” that they refuse to see them.

This is the field guide. Read a listing like a forensic accountant, not a hopeful buyer.

Why does “70% to 85% of collections” tell you almost nothing?

For decades, dentistry has priced practices as a percentage of top-line revenue — roughly 70% to 90% of collections in high-demand urban markets, and lower the further out you go. It’s the laziest metric in the industry, and it’s exactly why so many buyers overpay.

Percentage-of-revenue completely ignores profitability. A practice can collect $1M and net the owner almost nothing after real expenses. Another can collect $800K and throw off a genuine, transferable profit. Same “gross,” wildly different businesses. As the deals get bigger — generally north of $1.5M in collections — the smart money stops looking at revenue and starts underwriting EBITDA: revenue, minus overhead, minus a fair market wage for the dentistry the owner personally produces.

Here’s the red flag that gut-punches new buyers: when you pay yourself a real associate-level wage for your own production, a lot of “profitable” practices reveal they have almost no profit left. You didn’t buy a business. You bought yourself a job — and financed it at 10%.

What are the numbers a seller can’t (or won’t) answer?

The fastest way to spot a rotten listing is to ask three plain questions and watch the seller squirm:

• “What were your actual collections the last three years — not production, collections?” If they only know “gross” and can’t tell you the trend, run. A shocking number of sellers genuinely don’t know their own numbers.
• “What’s your net profit percentage after you pay a fair wage for your own dentistry?” Vague answers here mean the profit doesn’t exist.
• “Is revenue growing, flat, or declining?” This is the one that matters most.

Declining revenue is the single most dangerous line item in any listing. Overhead never goes down over time — it only goes up. So a practice sliding from $1.1M to $950K to $820K is quietly strangling its own cash flow, even if the seller “felt fine” because their debt was paid off years ago. You inherit the decline and a fresh acquisition loan. That’s how profitable-looking practices go broke in year one.

Which red flags are hiding in plain sight on the listing?

Beyond the money, these are the structural warning signs Pete and Craig flag again and again:

• The entire value is the departing doctor. If the practice only works because that specific dentist is chairside — their personality, their hands, their relationships — then there’s no transferable business. Buyers today are (rightly) far less willing to pay for goodwill they’ll never actually inherit. Patients are too savvy to keep showing up for a doctor who isn’t there anymore.
• Junky equipment and zero recent investment. “Turnkey” often means “I stopped spending on this place five years ago.” Aging chairs, no digital imaging, no scanner, tired ops — that’s deferred capital expense you’re about to eat, on top of the purchase price.
• A wrecked accounts receivable program. Some practices are running 20–30% behind on AR. That’s money already earned but never collected — and it signals broken systems throughout the office. The flip side: it’s also opportunity. Tighten AR and utilization and you can add several points of EBITDA within months of closing.
• A plummeting new-patient trend. New patients are the leading indicator for everything. When that number falls, hygiene empties out first, then restorative. If the listing conveniently omits a monthly new-patient chart, ask for it. The absence is the answer.
• Low chair utilization. Look at net production divided by total available chair-hours (operatories × hours open). A practice with empty chairs isn’t a disaster — it’s untapped capacity you can fill. But you should be paying a “problem” price for it, not a “perfect” price.

How do you tell a fixer-upper from a money pit?

Not every flaw is a dealbreaker. This is where amateurs and operators separate. A busy, well-located practice — good demographics, modern tech, real profitability — is a seller’s market; brokers can generate multiple offers with five phone calls. You’ll pay full price and you should.

The opportunities live in practices with fixable problems: weak AR, poor scheduling, low utilization, no marketing. Those are systems failures, and systems are exactly what a trained operator installs. What you cannot fix easily: a dying patient base in a shrinking town, a lease you can’t control, a location nobody drives to, or a seller whose leaving vaporizes the revenue. Fixable = mispriced. Structural = trap.

Run every listing through one question: “After I pay debt service and a fair wage for my own production, is there still real profit — and can I grow it with systems I actually know how to run?” If the honest answer is no, no valuation gymnastics will save you.

Where do most buyers actually go wrong?

Craig’s point cuts to the heart of it: the biggest risk isn’t the practice — it’s the buyer’s emotion. Fear (“the money’s here now, better move before consolidation eats everything”) and ego (“I’ll finally be an owner”) make dentists ignore numbers screaming at them from the page. The consolidators and the fear-drum marketers count on exactly that.

The defiant move is to stay independent and stay disciplined. Buy on the math, not the story. Get a real forensic valuation before you fall in love. And do it with people who’ve read a hundred of these listings — not alone at your kitchen table at midnight.

That’s the whole reason Bulletproof exists. Dentistry is a lonely profession, and buying a practice is the loneliest, highest-stakes decision most dentists ever make. It shouldn’t be. Inside the Bulletproof Mastermind, owners pressure-test deals with peers who’ve already done it — before the wire, not after. Every year at the Bulletproof Summit, we tear these frameworks apart on stage so you never sign blind.

You don’t have to read the next listing alone. Find your tribe, bring the numbers, and let people who’ve been there tell you the truth. Because the best deals aren’t the ones with the prettiest packets — they’re the ones you understood completely before you said yes.
