Treat the Cause, Not the Symptom: How Workforce Architecture Can Stop Dark Columns Before They Start

“What am I spending on temps to fill gaps, and is it worth it?”

Many of you have asked this question when weighing your growth strategy. And while I agree you should be questioning your staffing mix and coverage gaps, let me pose another question for you to consider, one that never shows up as a line item:

What production is possible from a covered column, no matter who fills it?

This question is the essence behind workforce architecture, and it’s the key to unlocking a staffing model that drives your practice’s growth.

Let’s dive into what that means.

What is the airline analogy for dental groups?

Think of an airplane seat.

An airline only makes money when a seat is filled. If a plane takes off with an empty seat, whatever it could have earned is gone the moment the plane leaves the tarmac, and it can’t be recovered. So a filled seat, whether sold at full price or at a discount, is better than an empty one.

To take the analogy a step further, a rescheduled passenger doesn’t generate new profit. They give up their original seat, losing whatever it could have earned, and then take the place of a new potential passenger on the rescheduled flight.

Are you with me so far? Here’s the punchline:

The same principle applies to the hygiene chair.

A hygiene chair only turns into production when a hygienist is there to see a patient. Once a column goes dark, that production can’t be recovered. Moving the patient is a short-term administrative fix, not a revenue-recovery one, because production can only be replaced, not moved.

It’s widely understood that rescheduling a patient from a dark Tuesday to an active Thursday doesn’t generate anything net-new. What’s most often overlooked is the double loss: Thursday's slot goes to a patient you already had, instead of one you didn't.

That’s where workforce architecture comes in.

What is workforce architecture?

Let’s go back to the initial question I posed: What production is possible from a covered column, no matter who fills it?

Workforce architecture gives us a clue because it’s a staffing model designed to avoid dark columns altogether. It shifts the focus from why one shift went unfilled to the real leak: every dark column, whatever the cause. Workforce architecture helps ensure full production is captured with the deliberate mix of full-time staff, internal float pool, and outside coverage.

To help illustrate why a covered column is so important, let’s take a look at what one dark hygiene day a month adds up to in a year.

Kwikly research found that a single day of hygiene production ranges from $2,500 to $4,000 when you include downstream treatment. At that rate, one dark hygiene day a month adds up to as much as $48,000 a year in lost production.

Take away the hygienist, take away full production potential.

Workforce architecture reduces the probability of a dark column staying dark by increasing a practice’s coverage options. These options include layers that likely exist already, just not in a cohesive mix. They include your permanent staff, internal float pool and outside support. Let’s break them down further.

Permanent staff are the most straightforward. These are your established, full-time team members. They can step in when their colleagues are out and populate some of the internal float pool.

Internal float pools simultaneously bring alumni and part-time professionals back into the picture. Former staff who left on good terms, recent retirees, parents who have one day a week open. These are people who already know your practice and are welcomed back into the staff. With a structured float pool, it is a win-win: you get your shifts covered, they control their schedule.

The third layer is external support as needed. Because we’re talking about real people, real life happens. Backup support that fills the shifts no one else claims keeps the system humming.

Working in tandem within an organized workforce architecture, these three layers can put dark columns into the rearview.

How to start designing your workforce architecture

Many offices have the internal staff available. They use outside vendors. Dentists may even call a former assistant to help them from time to time. Workforce architecture organizes these layers into one operating system that pulls on them strategically to fill gaps.

If you’re wondering how to design your workforce, here’s where to start:

1. Pull the numbers on last quarter's dark columns. Determine how many hygiene days went unworked that no one could fill.
2. Multiply that by your average daily hygiene production. This will be an eye-opener and truly put a figure to what is lost without proper coverage.
3. Consider your float pool roster. List alumni nearby, anyone who wants more flexibility, and team members at nearby offices in your group. This will be your shortlist.
4. Finally, decide who covers what before the call-out happens. Permanent staff might flex for same-day sick calls, the float pool for planned PTO, and outside support for longer gaps or anything no one else claims.

Remember, workforce architecture isn’t the goal. Covered columns are, and they’re your lever for same-store growth. An organized workforce is the difference between reduced backlogs, shorter waits, fewer dark columns and, yes, less stress, and the scramble you’re used to.

By designing your workforce, you protect your production.
