Would Your Assistant Tell You If You Were About to Make a Mistake?
Psychological safety in a dental practice is not a soft nicety — it's a clinical safeguard, because a team member's willingness to speak up can be the difference between a caught error and a harmed patient. Amy Edmondson's research shows that “steep authority gaps silence people exactly when speaking matters most,” from cockpit crashes to hospital errors; the owner-led practice has one of the steepest gaps of all. Daniel Coyle's finding points to the fix: “vulnerability precedes trust, so the doctor goes first — admitting mistakes, asking for input, and thanking anyone who catches something.” The decisive moment is how you react when a team member questions you: reward the catch every time, even when they're wrong, and build safety through small, repeated belonging cues like a real daily huddle. This is the Back movement of The Hanlon Potential Model™ — See, Grow, Back. The weekly move: tell your team you want to be corrected, and thank the next person who does.
You're behind schedule and moving fast. You reach for the chart; you're set to begin — and something is off. Maybe it's the wrong quadrant. Maybe there's a note about a medication you didn't catch. Maybe your assistant sees it before you do. Here's the question that matters more than almost anything else in your practice: does she say something? Or does she assume you know better — or worse, notice, hesitate, and stay quiet because the last time someone corrected you, it didn't go well?
In most businesses, silence costs money. In a dental practice, it can cost a patient. This week we've been talking about psychological safety — making it safe for people to speak up. Today it comes chairside, where that safety isn't a nicety. It's a clinical safeguard, and building it is one of the most important things you'll ever do as an owner.
Key Takeaways
• In a practice, a team member's silence can be the difference between a caught error and a harmed patient.
• The steep authority gap between doctor and team makes people hesitate to speak — exactly when speaking matters most.
• Coyle's rule holds chairside: vulnerability precedes trust, so the doctor has to go first.
• How you react the moment someone questions you sets the price of honesty for your whole team.
• Small, repeated belonging cues — like a real daily huddle — build the safety that keeps everyone speaking.
• This is the Back movement of The Hanlon Potential Model™ — protecting your team's voice, literally.
In a Practice, Silence Can Harm a Patient
Amy Edmondson's research in The Fearless Organization opens with life-and-death examples for a reason. She points to the Challenger and Columbia shuttle disasters, and to a 1977 runway collision that killed 583 people because a co-pilot was unwilling to challenge his captain. In every case, someone knew — and the culture made speaking up feel too risky. She notes the same dynamic in hospitals, where lives are saved when a nurse feels not just able but obligated to question a physician.
Dentistry lives in that same territory more than we like to admit. A missed line in the medical history, an allergy no one flagged, the wrong tooth on a busy afternoon — these are the moments where a team member's willingness to speak is a genuine clinical safeguard. If the people around your chair don't feel safe to say “Doctor, can I check something?”, you've removed a layer of protection that has nothing to do with their competence and everything to do with your culture.
The Authority Gap in the Operatory
Every workplace has an authority gradient, and in an owner-led dental practice it is steep. You are the doctor, the boss, the expert, and often the person who signs the checks — all at once. Edmondson's finding applies with full force: “no one wants to take the interpersonal risk of imposing ideas when the boss appears to think he or she knows everything.” The steeper the gap, the more courage it takes to speak, and the more likely people are to swallow a concern rather than voice it.
That gap isn't something you can eliminate — you are the clinician, and the buck stops with you. But you can flatten how it feels. The goal is a team that respects your authority and still feels free to flag what they see, because they know you'd rather be interrupted than be wrong. Getting there is a deliberate act of leadership, and it runs against every instinct that says the doctor should never be questioned.
Vulnerability Goes First
Daniel Coyle's research in The Culture Code gives the mechanism: “vulnerability precedes trust, not the reverse. Your team won't feel safe correcting you because you told them to. They'll feel safe because you went first — because they've watched you admit your own mistakes, say “I'm not sure, what do you think?”, and thank someone for catching something you missed.”
I saw this at every scale of my career, from running six practices to overseeing two dental school clinics with hundreds of students and residents working at once. The environments where people spoke up and errors got caught were never the ones with the most intimidating leader. They were the ones where the person in charge had made it unmistakably clear, through their own behavior, that being corrected was welcome. A doctor who can say “good catch, thank you” in front of the team does more for patient safety in that one moment than any policy manual on the shelf.
Reward the Catch — Every Time
Here is the moment that decides everything, and it's smaller than you'd think. Someone on your team questions you — “Are we sure about that tooth?” — and you turn out to be right. What you do in the next three seconds writes the rule for your whole practice. Snap back, get defensive, or make them feel foolish, and you've just taught everyone watching to never question you again, including the time it would have mattered. Say “I'm glad you asked — always ask,” and you've reinforced the exact behavior that protects your patients.
So reward the catch every single time, especially when the person was wrong. The willingness to speak up is worth infinitely more than being right in the moment, because you cannot have the life-saving interruptions without also welcoming the unnecessary ones. A team that gets thanked for false alarms is a team that will also sound the alarm that counts. A team that gets punished for false alarms learns to stay silent through both.
Build Safety in the Daily Rhythm
Coyle's research shows safety is built through belonging cues — small signals, repeated until people believe them. In a practice, you have a perfect vehicle for those cues sitting in your schedule already: the daily huddle. Used well, it's not just a logistics meeting. It's a standing ritual where every voice is invited, where you ask “what should I know about today's patients?”, and where the newest assistant's observation is treated as seriously as anyone's.
The specifics matter less than the consistency. Thank people generously and by name. Ask genuine questions and actually listen to the answers. Include the quiet person on purpose. Admit when you don't know something. None of these are grand gestures, and that's the point — a safe team isn't built in a single dramatic conversation, but in the accumulation of hundreds of small moments where people learn, again and again, that their voice is wanted here.
The Hanlon Potential Model™, Chairside: Back Begins With Safety
This month's framework, The Hanlon Potential Model™ — See, Grow, Back — reaches its final movement. You saw your team's potential, you grew it through coaching, you handed over real ownership. Backing them is where it all becomes real, and in a practice it starts with something concrete: protecting their voice, literally, so the people around your chair will always tell you what they see.
The move for this week is direct. Tell your team, out loud and plainly, that you want to be corrected — that if anyone ever sees something that looks off, clinical or otherwise, you would always rather they speak than stay quiet. And then the very next time someone does, thank them like it mattered, because it did. That's how you turn the people you've grown into a team that has your back and your patients' — and it's the truest form of leadership there is.
Final Thoughts
The safest practices aren't the ones with the most impressive doctor. They're the ones where every person around the chair feels free to say “wait” — where the assistant, the hygienist, and the coordinator all know that speaking up is not just allowed but wanted. That kind of safety catches the errors that credentials never will, and it's built entirely by how you, the owner, respond when someone is brave enough to question you.
So this week, tell your team you want to be corrected, and mean it — then prove it the next time someone does. You've spent this month seeing your people, growing them, and handing them real ownership. Backing them, here, means protecting their voice so it can protect your patients. That's not just good leadership. In a dental practice, it's the safest thing you can build.
Frequently Asked Questions
-
It does the opposite. Teams respect a leader who is confident enough to be questioned far more than one who demands never to be. Your clinical authority is intact — you still make the call. Welcoming input signals security, not weakness, and it's what makes people trust you with the truth.
-
Thank them anyway — that's the whole point. You cannot get the catch that matters without also welcoming the false alarms. A quick “glad you checked, we're good here” costs you nothing and keeps the channel open. Punishing a wrong flag closes it for good.
-
The huddle isn't overhead; it's a few minutes that prevent far costlier problems later — a missed medical alert, a scheduling collision, a patient concern no one flagged. And the safety it builds is the kind that catches the mistake you'd otherwise make on exactly the busy days you feel too rushed to meet.
-
Go first, and be patient. Admit a mistake of your own in front of them, ask genuinely for input, and — crucially — respond well the first few times someone tests whether it's really safe. Trust rebuilds through repetition, not a single announcement. Your consistency over the next month matters more than any one conversation.
