Summer Staffing: Vacation Coverage Strategy That Doesn't Tank Your Production

Vacation weeks don't tank production. Unplanned vacation weeks do. The practices that lose $30,000 over a summer aren't the ones whose hygienists took time off. They're the ones who approved five requests in April without checking them against each other, discovered in June that two hygienists and an assistant were out the same week, and then ran a half-empty schedule because there was nothing left to do about it by then.

The fix is three moves, and all three happen before anyone submits a request. Cap how many clinical people can be out at once. Publish the blackout weeks and the open weeks yourself. Then treat the covered weeks as the place you deliberately stack production, not just the weeks you survive.

Late September is the right time to do this. Next summer's calendar is still empty, your team hasn't made deposits on anything, and you have three quarters of runway to line up temp relationships before every other practice in your zip code is calling the same agency in May.

Why Summer Breaks Hygiene First

Your hygiene department is load-bearing in a way most owners underprice. It generates its own production, and it generates the diagnosis that fills the doctor's column six weeks later. Lose a hygiene day and you lose twice, once now and once next quarter.

It's also the hardest seat to backfill, and that isn't a local problem. Only 60% of dentists report having an adequate number of dental hygienists on staff, and among those actively recruiting, 91% say hiring a hygienist is very or extremely challenging, per the American Dental Association Health Policy Institute. Staffing generally is the thing owners are most worried about: roughly 3 in 5 dentists named recruiting and retaining staff as their top expected challenge in ADA Health Policy Institute polling.

Read those two numbers together and the summer problem gets clear. If you are short a hygienist in a normal week, you are not short one, you are short two during vacation season, and the open market you'd normally lean on is thin. A temp agency with one hygienist available on July 8 is fielding calls from every practice within 40 miles. The relationship you built in October gets that hygienist. The practice that called on July 6 does not.

Publish the Calendar Before Anyone Asks

Most vacation policies are reactive. Someone asks, you say yes because saying no feels bad, and the conflicts stack up invisibly. Flip the order.

• Set the cap first. One hygienist out at a time, and never a hygienist and the assistant who supports your busiest doctor column in the same week. Write the cap down as a number, not a vibe, so the second request that breaks it gets declined by the policy instead of by you.
• Name the weeks you will not staff down. The week after the July 4 holiday and the back-to-school stretch in mid-August tend to carry heavy hygiene volume, because parents book kids before school starts. Protect those.
• Open requests on a date, first come, and post the grid where everyone sees it. A visible grid does the negotiating for you. Two people who both want the same week will work it out between themselves if they can see the conflict in November. In May they will both come to you and one will leave unhappy.
• Require a 60-day lead on anything longer than three days. That's the amount of notice a temp agency actually needs to place someone good.

This costs nothing and it's the single highest-return thing on the list, because it converts an unpredictable production hole into a scheduled one. A scheduled hole you can fill.

The Coverage Options, Ranked by What They Actually Cost

You have four real choices, and owners consistently misjudge the order.

Straight-time pickup from your own team. If your hygienists work four eight-hour days, a fifth day is 40 hours for the week, which means it's straight time, not overtime. This is the cheapest coverage that exists and most practices never offer it, because they assume any extra day triggers a premium. It doesn't. Ask first, before you call anyone.

A temp hygienist through an agency. Predictable, no payroll tax handling on your side, and the rate is a known number you can plan against. The catch is availability in July and quality variance. A temp who needs 20 minutes of onboarding per chair costs you more than the hourly rate suggests.

Overtime past 40 hours. More expensive per day than a temp in most markets, and it's the option most likely to cost you a hygienist in September. Burning out the person who covered everyone else's vacation is how you end up recruiting into a market where 91% of your peers call it very or extremely challenging.

Compressing the schedule. Two hygienists out the same week and no temp available: run four days instead of five and move the fifth day's recall patients into the covered weeks. You lose a day of chair time but you don't run a day at half capacity with a confused temp, and you don't pay for coverage you can't use. This is the honest fallback, not a failure.

Operator Math

Here's the scenario, using BLS wage data for the cost side and your own production numbers for the revenue side. Practice with three hygienists, each working four eight-hour days a week, each producing $1,100 a day in hygiene. Swap in your real per-day production before you act on any of this.

Each hygienist takes two weeks off, so you're looking at six hygienist-weeks of absence across the summer. At four clinical days a week, that's 24 uncovered hygiene days. At $1,100 a day, the hygiene production sitting in those empty days is $26,400.

That's only the first half. Those visits also feed the doctor's column. If a dollar of hygiene production in your practice historically pulls 60 cents of restorative and perio behind it, the downstream exposure is another $15,840, for total production exposure of $42,240. Pull your own hygiene-to-restorative ratio rather than using 0.6, because this is the number that decides whether coverage is worth paying for.

Now price the coverage. The median hourly wage for dental hygienists was $47.16, or $98,100 a year, as of May 2025, across 225,300 jobs, per the U.S. Bureau of Labor Statistics. Start with the part people forget: you're already paying for the vacation. Two weeks of PTO at that median is $3,773 per hygienist, or $11,319 for all three. That money leaves the building whether the chair runs or not, so every coverage option below is incremental spend against $42,240 of exposure, not spend on top of nothing.

Straight-time pickup: a hygienist at $47.16 adding a fifth eight-hour day costs $377.28 for that day. Cover all 24 days this way and you spend $9,054.72.

Temp agency at a quoted $65 an hour: $520 a day, or $12,480 for 24 days. Against the $26,400 of hygiene production alone, that leaves $13,920 before you count a dollar of downstream restorative. The temp pays for itself roughly twice over on hygiene production by itself.

Overtime past 40 hours: $47.16 at time and a half is $70.74 an hour, or $565.92 a day. That's $45.92 a day more than the temp quote and $188.64 more than straight-time pickup. Overtime is the expensive option, not the convenient one.

Don't forget the assistant side. The median annual wage for dental assistants was $48,070, or $23.11 an hour, as of May 2025 across 388,600 jobs, per the U.S. Bureau of Labor Statistics. A covering assistant at straight time runs $184.88 for an eight-hour day. Adding an assistant to keep two doctor columns moving during a thin week is the cheapest production protection on the whole list, and it's the one most owners skip.

The summary: spending somewhere between $9,000 and $12,500 to protect $42,240 is not a close call. The mistake isn't paying for coverage. It's failing to line it up in time to have the option.

Fill the Covered Weeks on Purpose

Coverage keeps the chair occupied. It doesn't keep it productive. Two things to do in the six weeks before each gap:

Pull recall forward. Anyone due in the uncovered week gets called in April and offered a slot in the weeks on either side. You're not cancelling on them, you're offering them a better time before the calendar tightens. The patients who say yes convert a future empty day into a currently booked one.

Match case type to who's in the chair. A temp on day one should see straightforward prophy and children's recall. Your established perio maintenance patients, the ones with a history and a scaling protocol, belong in the weeks your own hygienist is present. Sorting the schedule this way costs one afternoon of admin and it's the difference between a temp day that produces and a temp day that generates three reappointments you have to chase.

When the Owner Is the One Leaving

Doctor vacations get handled worst of all, usually by cancelling two weeks of production and calling it the cost of a trip. It isn't. Locum tenens coverage for dentists is a real, regulated mechanism, not a workaround. Nebraska, for example, issues a dentist locum tenens permit valid for up to 90 days in any 12-month period, specifically to replace a dentist who will be unavailable, including for vacation. Your state's rules will differ, so check your board before you plan around it, but the point stands: a legal path to keeping your column open usually exists.

Run the numbers the same way. A doctor column producing $4,500 a day, out for 10 days, is $45,000 of production. Assume the locum produces at 70% of your rate, which is realistic for someone learning your team and your patients, and you recover $31,500. At a negotiated $1,100 a day, the locum costs $11,000 for those 10 days, leaving $20,500 of production you'd otherwise have zeroed out. Meanwhile your rent, your loan payment, and your front desk payroll run at full cost through both weeks either way.

The other reason this matters: a closed office for two weeks pushes every emergency patient to whoever answers the phone. Some of them don't come back.

Three Ways Owners Make This Worse

Denying vacation to protect the schedule. In a market where 3 in 5 dentists rank staffing as their top challenge, a denied summer request is a resignation you'll receive in the fall. Replacing a hygienist costs multiples of what any temp week costs.

Letting people cash out PTO instead of taking it. Feels efficient, produces a team that has not had a real break in three years and an accrued liability on your books. Neither helps you.

Waiting until the request comes in to think about coverage. Every option above gets cheaper with lead time and more expensive without it. Straight-time pickup requires asking someone who hasn't yet booked their own trip. Temp placement requires a relationship. Locum coverage requires a permit application. None of that happens in a week.

The Takeaway

Build next summer's absence grid this fall, set a hard cap of one clinical person out at a time, and publish it before you take a single request. When the gaps are visible, offer straight-time fifth days to your own team first (cheapest coverage there is), call your temp agency second, and treat overtime as the last resort it actually is on a per-day basis. Pull recall forward into the covered weeks and route perio maintenance away from temp days so coverage produces instead of just filling space. If you're the one leaving, check your state board's locum tenens rules now rather than closing the doors and eating the production.

Most of this comes down to one question: what does a clinical day cost you when it doesn't run, and what is your staffing already costing as a share of production? If you don't have those two numbers cold, you can't tell whether a $520 temp day is a bargain or a waste. Our free overhead calculator breaks staffing cost out as a percentage of production, so you can see what your team actually costs per clinical day and price coverage against it instead of guessing. Run your own numbers before you approve a single summer request.
