How Much Does a Dentist Vacancy Cost a DSO?

A dentist vacancy can put a meaningful amount of clinical capacity at risk, but the useful number depends on the seat, patient demand, how much work other providers can absorb, and how long the vacancy stays open. The goal is not to repeat a dramatic generic industry number. It is to calculate a planning estimate the DSO can defend.

For certain full-time dentist seats, MBS uses roughly $80,000 to $120,000 in monthly production opportunity as a planning range. Over 90 days, that represents roughly $240,000 to $360,000 in gross clinical capacity associated with the seat before any assumption about demand absorption. It is not a universal benchmark, lost-revenue figure, or profit estimate.

Use two numbers, not one

Gross clinical capacity associated = monthly provider production opportunity × vacancy duration.

Adjusted unabsorbed vacancy exposure = gross clinical capacity associated × percentage of demand not absorbed elsewhere.

This distinction matters. A provider may normally support substantial monthly production, but some patient demand can shift to another clinician, be rescheduled, be delayed, or be recovered later. The gross number describes the capacity associated with the empty seat. The adjusted number estimates the share leadership believes is not being absorbed elsewhere during the vacancy.

A simple 90-day example

Assume a provider seat normally supports $100,000 per month in production opportunity and remains vacant for three months. Gross clinical capacity associated with the seat is $300,000.

If leadership estimates that 70% of the associated patient demand is not absorbed elsewhere during that period, adjusted unabsorbed vacancy exposure is approximately $210,000: $100,000 × 3 months × 70%. The 70% assumption is illustrative. A DSO should replace it with its own operating estimate.

That $210,000 is still a planning estimate, not an accounting entry. It gives leadership a more transparent way to compare the business exposure with the recruiting response being used to address it.

The same 90-day vacancy can create very different exposure

These examples illustrate the method rather than a benchmark:

• $80,000 monthly capacity × 3 months = $240,000 gross; at 50% unabsorbed demand, adjusted exposure ≈ $120,000.

• $100,000 monthly capacity × 3 months = $300,000 gross; at 70% unabsorbed demand, adjusted exposure ≈ $210,000.

• $120,000 monthly capacity × 3 months = $360,000 gross; at 80% unabsorbed demand, adjusted exposure ≈ $288,000.

This is why vacancy count alone can be misleading. Two DSOs can each have five open doctor seats and face very different business exposure depending on seat economics, patient demand, specialty, geography, and the capacity of the rest of the network to absorb care.

The empty chair is only part of the operating impact

A vacancy can affect more than the modeled production exposure. New-patient access may tighten. Existing providers may carry more workload. Specialty referrals can leave the network. A de novo may ramp more slowly. An acquisition may take longer to reach the operating plan leadership expected.

Those effects should be discussed separately rather than hidden inside one inflated dollar estimate. The financial math should remain transparent; the operational implications can then be layered beside it.

Not every vacancy deserves the same urgency

Vacancy age matters, but I would not prioritize open seats by age alone. A newer Oral Surgeon opening with no active pipeline and significant referral impact may deserve more attention than an older GP opening where demand is lower and other doctors can absorb much of the schedule.

• What is the realistic monthly production opportunity for this seat?

• How much associated patient demand can other providers realistically absorb?

• Does the vacancy affect patient access, specialty referrals, a de novo, an acquisition, or another growth commitment?

• How difficult is the specialty and market?

• How many current qualified clinician alternatives are in the pipeline?

Turn the exposure into a recurring operating decision

For priority seats, recalculate the model as vacancy duration, patient demand, provider absorption, and pipeline depth change. A new month of vacancy should not automatically trigger more recruiting spend, but it should trigger a decision about whether the current sourcing coverage, candidate pipeline, interview speed, compensation, and market strategy are proportionate to the exposure being carried.

The right question is not simply, “What does recruiting cost?” It is, “What capacity and demand remain exposed while this seat stays open, and what would realistically reduce the time to an operational provider?”

Where Dental Workforce Infrastructure fits

Vacancy economics are one reason MBS treats recruiting as part of Dental Workforce Infrastructure. Earlier demand visibility, current clinician pipelines, enough recruiting capacity, and faster candidate decisions give leadership more ways to reduce the period between recognizing provider demand and putting clinical capacity in place.

MBS is also building a Dentist Vacancy Cost Calculator using this same two-step method so leaders can enter their own provider capacity, vacancy duration, and demand-absorption assumptions. The article and tool should use the same definitions rather than competing formulas.

Frequently asked questions

Is vacancy exposure the same as lost revenue?

No. Gross clinical capacity associated with an open seat is not the same as lost revenue. Some demand may be absorbed by other clinicians, delayed, rescheduled, or recovered later. Adjusted unabsorbed exposure is still a planning estimate, and production is not the same as profit.

Should a DSO use an industry average for every dentist vacancy?

No. Start with the actual production history or realistic production opportunity for the specific seat, then apply the actual vacancy duration and the organization’s own estimate of the share of patient demand not absorbed elsewhere.

How should specialist vacancies be handled?

Use the same transparent framework, but consider specialty-specific economics and operating effects such as internal referral leakage, procedure mix, scarcity, geographic coverage, and the amount of patient demand the network can realistically retain or absorb.

Where should leadership start?

Start with the highest-priority open and forecasted seats, calculate gross capacity and adjusted unabsorbed exposure separately, review current pipeline depth, and decide whether recruiting capacity matches the operating risk. The Dental Workforce Infrastructure Assessment can help leaders evaluate that broader system.
