7 Partnership Mistakes That Cost Dentists Time and Money

A dental partnership usually starts the same way: hopeful, handshakes all around, maybe even a celebratory dinner where everyone swears, “This is going to be great.” I’ve seen it, I’ve lived close to it, and I’ve heard the war stories. Two doctors are sitting in a coffee shop with their laptops, excited to finally have someone to share the load with. In that moment, it feels like the safest, smartest decision of their careers.

Fast forward a few years… and sometimes those same partners can’t even make eye contact in the hallway.

The truth? Partnerships can be powerful, but when the cracks show, they get expensive fast, financially, emotionally, and even clinically. So here are seven mistakes I’ve seen dentists make that end up costing more than they ever imagined.

1. Skipping the Money Talk

Money makes people weird. Even best friends. One dentist I knew pulled distributions to remodel his kitchen while his partner was quietly putting off a family vacation just to keep personal cash flow in check. Guess how long it took for resentment to bubble up?

The mistake isn’t in the kitchen. It’s never sitting down and saying, “Here’s how we’re going to handle profits. Here’s what’s fair.” If you don’t hammer that out, every dollar becomes a silent competition.

2. Trusting a Handshake Over Paperwork

It’s romantic to think, we’re professionals, we don’t need lawyers. But try explaining “trust” in front of a judge after litigation starts.

Partnership agreements aren’t just legal fluff; they’re your playbook when emotions run high. Who buys who out? How are profits split? What happens if one of you wants to slow down? If that isn’t clear on paper, someone will pay dearly to figure it out later. Usually, both of you.

3. Pretending Equal Profits = Equal Work

This one stings. I’ve watched partnerships crumble because one doctor worked 40 hours a week while the other coasted at 28. On paper, their paychecks looked the same. In reality, one was exhausted and bitter, the other defensive and detached.

Counting patients like tally marks on a prison wall isn’t healthy, but neither is pretending effort doesn’t matter. Clear systems for measuring contribution matter more than “trust me, bro.”

4. Keeping Personal Finances a Secret

Here’s where it gets messy. Imagine refinancing your practice loan, only to discover your partner has a tax lien you never knew about. Suddenly, the bank won’t move forward, the deal stalls, and your collective dream gets torpedoed.

That’s not just a financial hit, it’s betrayal by omission. Partnerships mean shared tax IDs, shared liabilities, and, unfortunately, shared skeletons. If you’re not being transparent about personal debts or messy divorces, you’re handing your partner a live grenade without telling them.

5. Ignoring Clinical Philosophies

You’d think it’s all business, but no, dentistry itself can split a partnership. One dentist pushing full-mouth cosmetic makeovers, another happy with bread-and-butter restorative work. Patients get confused. Staff whispers about “whose way is right.” Suddenly, your office feels like two practices awkwardly stitched together.

Partnerships thrive when there’s alignment on treatment philosophy. Without it? You’re just running parallel clinics under one roof, and that’s chaos waiting to happen.

6. Failing to Plan the Breakup

Nobody likes to think about the end when they’re still in the honeymoon phase. But here’s the thing: one day, someone’s going to want out. Retirement, burnout, relocation, life always shows up.

Without a clear exit strategy, the remaining partner can get trapped, forced into buying out shares at inflated values, or stuck with a hostile partner who doesn’t want to budge. It’s like avoiding a prenup because it feels “unromantic,” only to realize later that you’re chained to a sinking ship.

7. Forgetting That Business Is Emotional

Dentists are trained in precision, not conflict resolution. But partnerships don’t blow up over spreadsheets; they blow up over trust, pride, and the little human irritations that never get addressed. “He took another Friday off.” “She micromanages staff.” Tiny pebbles turn into avalanches.

If you don’t check in on the relationship, not just the numbers, you’ll wake up resenting someone you used to celebrate wins with. And that resentment? It costs more than any lawsuit.

Closing Thoughts

I’ve seen partnerships flourish beautifully. Shared overhead, shared ideas, shared laughs after a tough day, it can be wonderful. But only if you go in eyes wide open.

So if you’re a dentist dreaming about bringing on a partner, pause for a moment. Ask the awkward questions now. Put everything in writing. Share the skeletons, even the embarrassing ones. And for heaven’s sake, don’t assume “we’ll figure it out.” Because the cost of avoiding hard conversations is always higher than you think.
