The First 90 Days After Buying a Dental Practice: A Survival Playbook

| August 30, 2026

The keys are yours. The debt is yours. And here’s what nobody tells you: the first 90 days after buying a dental practice will decide whether you bought an asset or a liability.

Most new owners walk in on day one and start “improving” things. New software. New schedule. New vendors. New rules taped to the breakroom fridge. Ninety days later they’re wondering why their best hygienist gave notice and collections are down 12%. The transition didn’t fail because the practice was bad. It failed because the owner treated the takeover like a renovation instead of a relationship.

This is the playbook we wish every buyer had before they signed. It’s built from hundreds of conversations on the Bulletproof Dental Practice podcast with owners who bought, transitioned, and scaled — and the ones who nearly torched a good practice in the first quarter.

Why do so many dental practice transitions stall in the first 90 days?

Because the buyer confuses ownership with authority. You bought the equipment, the patient charts, and the lease. You did not buy the team’s trust, and you cannot finance it. Trust is the one asset that doesn’t transfer at closing.

Pete Boulden puts it in plain numbers: a practice producing $1.2M a year moves roughly $100K a month through that front desk and those chairs. Every person on that team is a load-bearing wall. Fire the wrong assistant in week two, or spook the office manager who actually knows where the money is, and you don’t get a fresh start — you get a cash-flow crater while you’re making a loan payment that assumes full production.

The math is brutal and simple: your acquisition loan was underwritten on the selling doctor’s numbers. Your job in the first 90 days is to protect those numbers, not reinvent them.

What should you actually change first? (Almost nothing.)

Here’s the counterintuitive truth from owners who’ve done it right: change nothing operational for the first 60 days except the things that are actively losing money.

Your first 90 days have exactly three jobs, in this order:

• Days 1–30 — Observe and stabilize. Learn every name, every role, every unwritten rule. Sit in the morning huddle; don’t run it. Watch how patients move through the building. Find out who the team actually goes to when something breaks — that person is your real office manager regardless of their title.
• Days 31–60 — Secure the money. This is non-negotiable. On one Bulletproof episode, a respected owner shared that she discovered she’d been embezzled from a month after she bought the practice out. New owners are the softest target in dentistry: distracted, trusting, and not yet fluent in their own numbers. Change the bank signatory. Pull daily deposit reports yourself. Reconcile collections against production every single day. Read your practice financials line by line.
• Days 61–90 — Introduce ONE change. Pick the single highest-leverage fix and implement it cleanly, with the team’s buy-in. Not ten changes. One. Earn the right to the next one by nailing this.

How do you win over a team that didn’t choose you?

This is where Craig Spodak’s voice matters more than any spreadsheet. Craig’s line — “either pay for culture or become prey to DSO vultures” — is the whole game in the transition window.

The team you inherited built a culture without you. On a great practice, that culture is your most valuable and most fragile asset. Craig describes the practices he admires most this way: the team took ownership of the culture, and they violently protect it against any newcomer. Guess who the newcomer is in the first 90 days?

You. You’re the outsider now. So don’t walk in as the savior. Walk in as the student.

• Meet one-on-one with every single team member in week one. Two questions: “What do you love about this place?” and “What would you fix if you could?” Then shut up and listen. You’ll learn more about the practice’s real economics in those conversations than in the entire due-diligence binder.
• Keep the selling doctor visible — briefly. A warm hand-off letter and a few weeks of the old owner introducing you to patients preserves the trust equity you paid for. A cold, abrupt swap tells patients “something changed” and some of them vote with their feet.
• Protect the culture before you shape it. Craig’s advice to owners is to be the ambassador of the culture, lead by example, and then get out of the way. In the first 90 days, “getting out of the way” often means resisting your own urge to prove you’re in charge.

What patient and financial systems must you lock down immediately?

Stabilize the machine before you optimize it. The non-negotiable checklist for the first 90 days:

• Credentialing and insurance. Start day one — it can take 90–120 days, and unbilled production while you wait for provider numbers is a silent killer. Nail down which plans are in-network and what the real reimbursement looks like.
• Recall and reactivation. The fastest, safest revenue in a transition is patients who already know and trust the practice. Make sure the recall system is running before you touch anything shiny.
• The daily scorecard. Production, collections, new patients, and open chair time — reviewed every day, by you, in your own hands. You cannot lead numbers you don’t look at.
• Vendor and supply contracts. Note them, don’t rip them out. Supply savings are real money, but renegotiating vendors in month one signals chaos to a team already nervous about the new boss.

When is it finally time to make the practice yours?

Around day 90 — once the team trusts you, the money is secure, and you understand why things are the way they are. That’s when you’ve earned the right to build. Not before.

The owners who scale to a second location, add implants, or drop insurance all have one thing in common: they got the transition right first. They treated the first 90 days as the foundation, not the demolition.

The dentists who get this right aren’t guessing. They’re borrowing 90 days of hard-won judgment from owners who already made the mistakes. That’s the entire point of the Bulletproof Mastermind — a room full of practice owners who’ve bought, transitioned, and scaled, so you never have to learn the expensive lessons alone. And every year at the Bulletproof Summit, those owners get in one room and hand you the playbook that took them a decade to write.

Dentistry is a lonely profession. Buying a practice makes it lonelier — until you find your people. You don’t have to run your first 90 days on instinct and prayer. You can run it with a tribe that’s been there.
