The Merry Go Round Tax: What High Turnover Is Really Costing Your Practice

The last three issues of this newsletter have been about what happens at the end — the DSO contract you signed without understanding, the practice that sat unsold because the story went cold, the data room the buyer’s QoE team dismantles while you watch. All of it is downstream of decisions made years earlier, when the practice was still being built.

This issue is about one of those decisions — or more accurately, one of those habits — that quietly erodes practice value long before anyone calls a broker.

High turnover is not a staffing problem. It is a tax. And most practice owners are paying it without ever seeing the invoice.

The Invoice Nobody Reads

When a team member leaves, the visible cost is the job posting. Maybe a recruiter fee. A few hours of interview time. That is what most owners count.

The actual invoice is longer.

Direct hiring costs — job board fees, recruiter commissions (typically 15–20% of first-year salary for clinical staff), background checks, onboarding materials, and the administrative time to process all of it — routinely run $3,000 to $8,000 per hire before the new employee sees their first patient. For a clinical role, the number is higher. For a hygienist in a competitive market, it can exceed $10,000 before you account for the weeks the chair sat empty.

The reputation cost — dental is a small professional community. Hygienists, assistants, and front desk coordinators talk to each other. A practice known in the local labor market as a place where people do not stay will pay a premium to recruit, attract a narrower pool of candidates, or both. That reputation compounds over time and is nearly impossible to reverse quickly. In an era where a two-star review on Indeed or Glassdoor is the first thing a candidate reads before deciding whether to apply, a pattern of turnover is a public record.

Lost signing bonuses and recruiter fees — when a practice uses a staffing agency to fill a role, the placement fee — typically 15 to 20 percent of first-year salary — comes with a guarantee window, usually 90 days, and with stipulations. If the hire leaves within that window and the separation meets the agency’s specific conditions, the practice may receive a credit toward a replacement search. If the hire leaves on day 91, or the circumstances of the departure do not satisfy the guarantee terms, the fee is not recoverable. Signing bonuses paid directly to candidates carry similar risk: a clawback provision is only as good as the practice’s willingness to pursue it, and most do not.

Lost production during the vacancy — a hygienist chair that runs 32 hours a week at an average of $150 per hour generates roughly $4,800 per week in production. A three-week vacancy is $14,400 in production that does not come back. It is not deferred. It is gone.

Some practices bridge longer vacancies with temporary staff, and temps can be a legitimate short-term solution. They keep the chair producing and prevent the schedule from collapsing entirely. Occasionally, a temp is good enough to hire permanently — it happens. But as a category, temporary hygienists are a mixed bag. They are typically sourced through agencies at a significant rate premium — often 30 to 40 percent above what a staff hygienist costs — and they arrive without the patient relationships, the clinical preferences of the doctor, or the operational context of the practice. The chair is filled. The relationship asset is not. Production tends to run lower than it would with a known provider, and the premium you are paying for the temp is compounding the cost of the vacancy rather than eliminating it. And if the temp turns out to be exceptional and you want to bring them on permanently, the agency will typically charge a conversion fee — a bounty for the hire — on top of every hour you have already paid at the premium rate. The best-case scenario with a temp still has a price tag most owners do not see coming.

The ramp-up drag — a new hire at full productivity is not a week-one phenomenon. For a front desk coordinator, the realistic ramp to full efficiency is four to eight weeks. For a clinical assistant, longer. For a hygienist who is rebuilding a patient relationship base from scratch, the production curve does not fully recover for three to six months. During that window, the practice is paying full salary for partial output.

Add it up across a single departure and replacement cycle, and the true cost of one turnover event in a mid-sized practice is rarely below $20,000. In practices with chronic turnover — two or three departures per year — the annual tax is $40,000 to $80,000 or more, paid quietly, never appearing as a single line item on any report.

The Patient Trust Problem

The financial cost is measurable. The patient trust cost is harder to quantify and more damaging in the long run.

Dental patients are creatures of habit and relationship. The hygienist they have seen for six years knows their anxiety about the upper left quadrant, remembers their daughter’s name, and has built the kind of trust that makes them keep their appointments and accept treatment recommendations. That relationship is not a soft benefit. It is a clinical and financial asset.

When that hygienist leaves and a new face appears at the next recall appointment, something shifts. The patient does not necessarily leave — but their engagement changes. They are less likely to accept a same-day treatment recommendation from someone they just met. They are more likely to “think about it” on a case that the previous hygienist would have closed. They may quietly start looking for a practice where the faces stay the same.

Consider the Trust Gap in practical terms. A patient with a five-year relationship with their hygienist operates at a fundamentally different level of clinical engagement than a patient meeting a new provider for the first time. Established patients accept treatment recommendations at significantly higher rates — not because the clinical need is different, but because the trust that enables acceptance has been built over years of consistent care. A new provider, regardless of skill, starts that relationship at zero.

Every time you lose a hygienist, you are resetting that trust for every patient on her schedule. In a practice with 1,000 active hygiene patients, that is 1,000 relationships that now have to be rebuilt — one appointment at a time, over months. The case acceptance that your departing hygienist had earned through years of relationship-building does not transfer. It evaporates.

The research on patient retention and staff consistency is consistent: practices with low turnover retain patients at higher rates, generate higher case acceptance, and produce more hygiene-driven restorative revenue. None of that is surprising. What is surprising is how rarely practice owners connect their turnover rate to their case acceptance rate when they are looking at the numbers.

The Training Drag

Every new hire is a temporary reduction in the practice’s operational capacity. This is not a criticism of new employees — it is simply the reality of how competence develops in a complex environment.

A dental practice is not a simple system. The scheduling logic, the insurance verification workflow, the morning huddle rhythm, the doctor’s clinical preferences, the way the team communicates about same-day treatment opportunities — none of this is written in a manual, and even when it is, reading it is not the same as living it. A new hire who is technically qualified on day one is still learning the practice’s specific operational language for weeks or months afterward.

During that period, the team absorbs the training load. The doctor answers questions they have not had to answer in years. The front desk covers gaps. The experienced team members slow down to bring the new one up to speed. This is not a complaint about new hires — it is a description of what training actually costs the people doing it.

In a practice with stable staffing, that cost is rare and manageable. In a practice with chronic turnover, it is a permanent condition. The team is always in some stage of training someone, which means the team is never fully operating at capacity.

What This Looks Like on the QoE Audit

For practice owners who have been following the exit strategy conversation, the connection is direct.

When a buyer’s Quality of Earnings team pulls your data, one of the things they are looking for is consistency. Consistent hygiene production. Consistent new patient flow. Consistent case acceptance. Consistent revenue per visit. These metrics are the fingerprints of a stable, well-run operation.

High turnover leaves a different fingerprint. Hygiene production that swings significantly quarter to quarter. New patient numbers that spike after a marketing push and then decay. Case acceptance that varies by provider in ways that suggest the relationship — not the clinical need — is driving the decision. An AR aging report that shows collection inconsistency across billing staff transitions.

None of these are fatal findings on their own. But they are the kind of operational variance that a QoE team uses to argue that the revenue is not fully sustainable — and that argument, applied to the EBITDA calculation, costs the seller at the multiple.

A practice with low turnover and stable staffing does not just run better. It tells a cleaner story. And in a transaction, the story is the valuation.

The Root Cause Question

High turnover in dental practices is rarely random. It clusters around a small number of root causes that, once identified, are addressable.

Compensation that has not kept pace with the market is the most common. The hygienist who has been with the practice for four years and is earning what she earned on day one is not a loyalty problem waiting to happen — she is a departure already in progress. The front desk coordinator who was hired at the bottom of the market range and has received cost-of-living adjustments but no merit increases is doing the same math.

Culture and leadership are the second. Teams leave managers before they leave practices. A doctor who is clinically excellent but operationally disengaged — who does not run a morning huddle, does not communicate treatment priorities, does not acknowledge the team’s contribution to the practice’s success — creates a vacuum that turnover fills. People who feel invisible leave. This is exactly what Joe’s book, The Root of Leadership, addresses: the systems and disciplines that keep teams intact and engaged over the long term.

Unclear expectations are the third. A team member who does not know what success looks like in their role, who has never had a performance conversation, and who has no path to growth or advancement will eventually find an employer who offers those things. This is not a generational problem. It is a management problem.

None of these are solved by a job posting. They are solved by the kind of intentional leadership that builds the conditions for people to stay.

What a Buyer Sees: The Scalability Discount

For any practice owner considering a future sale — whether to an individual buyer, a small group, or a PE-backed DSO — the staffing picture is one of the first things a serious buyer evaluates. The valuation method differs by practice type. Solo and single-location practices are most commonly valued as a percentage of trailing twelve-month collections — typically 60 to 100 percent, with the final figure driven by factors including payer mix, staff stability, patient retention, and the strength of the operational systems in place. Multi-unit groups and DSO targets are more often valued on an EBITDA multiple basis, where the same operational factors determine whether the buyer applies a premium or a discount to the earnings figure. The mechanism is different. The underlying logic is identical: a stable, well-documented practice commands more, and a merry go round practice commands less, regardless of how the math is structured.

This applies whether the buyer is a private equity firm running a formal Quality of Earnings audit or an individual dentist spending an afternoon walking the practice. The questions are the same. The conclusions are the same. Only the formality of the process differs.

The Scalability Problem

There is a deeper issue underneath all of this, and it connects directly to the valuation conversation.

A practice that commands a premium multiple — the 9x to 11x EBITDA that institutional buyers pay for platform assets — is not just a practice with strong revenue. It is a practice with documented, repeatable systems that can be operated, scaled, and replicated without the founding doctor at the center of every decision. That is what buyers are paying for. Not the revenue. The infrastructure that generates it.

In a practice with rampant turnover, that infrastructure almost never exists in written form. The scheduling logic, the treatment presentation workflow, the insurance verification process, the morning huddle rhythm — these things work because the owner knows how they work, and the long-tenured team member who has been there for six years knows how they work. When that team member leaves, the knowledge leaves with her. The new hire learns by watching, asking, and making mistakes. The SOP is never written because there is never a stable moment to write it.

This is the cycle that makes a practice unscalable. Constant turnover means constant retraining. Constant retraining means the team is always in a learning state. A team in a learning state cannot build the documentation that would make the next onboarding faster. And without documentation, the practice is entirely dependent on institutional memory that walks out the door every time someone gives notice.

A buyer’s QoE team will ask to see your standard operating procedures. A practice that cannot produce them — or produces a binder that has not been updated since 2019 — is telling the buyer that the practice runs on the owner’s knowledge, not on systems. That is a scalability discount. And scalability discounts are applied at the multiple.

A note for individual practice owners: The SOP conversation looks different at the solo level, but it matters just as much — and the upside is arguably greater. For a PE buyer or a multi-unit acquirer, documented SOPs are a baseline expectation. For an individual dentist buying a solo practice, they are a differentiator.

The individual buyer’s deepest fear is what might be called the Founder’s Vacuum — the worry that the moment you walk out the door, the “magic” leaves with you, because the magic was actually thirty years of your personal intuition. A well-documented set of operating procedures answers that fear directly. It tells the buyer: you are not purchasing a personality. You are purchasing a system. The team knows how to run it. Here is the reference.

This matters in three concrete ways. First, it eliminates handoff anxiety for the incoming owner — the team cannot say “that’s not how Dr. X did it” when Dr. X’s methods are written down and the new owner has read them. Second, lenders respond to it. A practice acquisition loan is easier to justify when the business case shows that the practice’s performance is systemic rather than personality-dependent. Banks lend against businesses, not against people. Third, it supports a premium on the collections-based valuation. A practice that can demonstrate it is genuinely turnkey — that it will run on all cylinders after the baton is passed — can justify sitting at the top of the 80 to 100 percent range rather than the middle. The difference between 75 percent of collections and 95 percent of collections on a $900,000 practice is $180,000. SOPs are not a bureaucratic exercise. They are a $180,000 document.

This is not only a concern for multi-location groups selling to private equity. The majority of dental practice sales involve a single buyer — an individual dentist, a small group, or a regional DSO — who will never commission a formal Quality of Earnings audit. But astute buyers at every level are now asking the same questions informally. They walk the practice. They talk to the team. They ask how long people have been there. They ask what happens when the owner is out. They notice whether the front desk can answer a scheduling question without calling the doctor, and whether the clinical team can describe the morning huddle without hesitating. Poor systems, visible turnover, and a culture that is clearly dependent on one person’s presence are deal-killers at any transaction size. The buyer does not need a forensic audit to see them. They just need to spend an afternoon in the building.

The Bottom Line

High turnover is not a cost of doing business in dental. It is a symptom of a practice that has not been designed to retain people — and the cost of that symptom compounds across every dimension of practice performance.

The practices that run well, retain patients, close cases, and command premium valuations at exit are not the ones with the best location or the most advanced equipment. They are the ones where the same faces show up every morning, know what they are doing, and trust the person leading them.

That is not an accident. It is a management decision, made every day, long before anyone calls a broker. If you are uncertain about the operational gaps driving turnover in your practice, the Trapdoor intake form is the first step to getting a forensic diagnosis.
