New year, same overhead: why January is your worst month

A hygienist costs about $8,175 a month whether the chair is full or empty. The median annual wage for dental hygienists was $98,100 as of May 2025, and that number does not know what month it is. Neither does your rent, your practice-management subscription, your equipment note, or the $48,070 median wage for a dental assistant. Production is seasonal. Overhead is not. That gap is why January, on paper the month of fresh starts, is the month that quietly takes the biggest bite out of your year.

Here is the claim most owners will fight: January doesn't lose you money. December does. The slow January you are about to have was already decided by the schedule you built in November and the treatment plans you let walk out the door in the last two weeks of the year. Blaming the benefit reset is a story owners tell themselves because it absolves the practice of a sales failure. We think that story costs a typical general practice five figures a year, every year, and most owners have never once measured it.

December Sells January, Not January

Start with the demand side, because it is real. Analysis of nationwide practice-management data from Sikka Software, reported by Dental Products Report, found January is one of the slowest months of the year on three separate measures at once: practice gross production, dentist production, and patients seen, all against the annual average. It isn't one weak metric. The whole month is soft.

The usual explanation is benefits. Dental PPO deductibles typically run $50 to $100 and reset on the plan's annual cycle, and about 65% of dental PPOs cap annual maximums at $1,500 or more, per the National Association of Dental Plans. So on January 2, a patient who had a fully spent maximum in December now has a fresh $1,500 but also a fresh deductible and a fresh out-of-pocket conversation. Patients feel that. They defer.

Fine. But notice what that mechanism actually tells you. The patient who hesitates in January is overwhelmingly the same patient who exhausted their maximum in the fourth quarter, which means they were in your chair recently, they already have a diagnosed plan, and you already know their coverage. That is not an unreachable market. That is your own patient list, scheduled badly.

Our view: the January slump is two different problems wearing one coat. There is a genuine demand dip of a few percent driven by benefit mechanics and holiday cash hangovers. Then there is a much larger, entirely self-inflicted hole created by a December front desk that spent three weeks squeezing in year-end cases and never once pre-blocked January. One of those you absorb. The other you built.

The $10,000 Hole in a $1M Practice

Let's price it. Take a five-operatory general practice collecting $1,000,000 a year. That scale is not invented: in the Practice Market Index, our own dataset built from dental practice broker listings, the median listed practice has 5 operatories (n=754) and median collections per operatory of $200,000 (n=643). Those figures describe practices currently on the market, the asking side, not all practices, but they tell you what a mid-market general office looks like in rough outline.

An even twelfth of $1,000,000 is $83,333 a month.

Call January 12% below that average, which is a conservative read of a month that underperforms on production and patient count simultaneously. You collect $73,333.

The shortfall is $10,000 in a single month.

Now the cost side, which does not move. Two hygienists at the $98,100 median come to $196,200 a year, or $16,350 a month.

Three assistants at the $48,070 median come to $144,210 a year, or $12,018 a month.

That is $28,368 of clinical wages a month before payroll taxes; add roughly 12% for employer taxes and you're at $31,772.

Add a two-person front office at $9,000 a month and rent at $6,500 and your fixed nut is $47,272 before you've bought a single burr, paid a lab bill, or serviced debt.

None of that shrinks when the schedule does. Which means the $10,000 January gap is not a 12% haircut on profit. It falls almost entirely to the bottom line. The American Dental Association's Health Policy Institute puts average 2025 gross billings per general-practice dentist at $965,660 against average net income of $215,320. Against a $215,320 take, a $10,000 January hole is 4.6% of your entire year's income, surrendered in 31 days.

Then there's the idle-chair version of the same number, which is the one that should actually sting. If each of your two hygienists runs 160 scheduled hours in January and comes in 25% unbooked, that's 80 hygiene hours gone.

At the median wage, a hygienist costs about $47.16 an hour before taxes and benefits.

So you paid roughly $3,773 in wages for hours that produced nothing.

And at $180 of hygiene production an hour, including the restorative those visits diagnose, you walked past $14,400 of production.

That's the real shape of January: a small cash expense and a large opportunity expense, and most owners only ever see the first one. They look at the P&L, see payroll was normal and collections were light, and conclude that January is just a bad month. It isn't. It's 80 hours of capacity you already paid for and then gave away.

What Most Owners Get Wrong About the Deductible Reset

The specific mistake, and it is near-universal among owner-operators running four to seven chairs without a dedicated scheduling coordinator: they treat January as a weather event and manage it defensively. Three defensive moves in particular, all of them wrong.

• Cutting hygiene days. An owner sees a thin second week and sends a hygienist home or drops a Friday. That saves maybe $400 in wages and destroys the recall capacity that fills February and March. Worse, it teaches a good hygienist that your practice is unstable in Q1, which is exactly when competitors with full schedules are hiring. We wouldn't cut a hygiene day in January under almost any circumstance. The wage is the cheap part of that hygienist; the continuity is the expensive part.
• The unused-benefits letter as the whole strategy. Nearly every practice sends the November "your benefits expire soon" email. Almost none of them do the obvious follow-on: segment the patients who did not respond and pre-book them into January on the new benefit year, with the deductible stated out loud. A patient facing a $100 deductible against a restored $1,500 maximum is in a better position in January than in December, not a worse one. Nobody ever tells them that.
• Discounting into the slow month. Whitening specials, new-patient loss leaders, membership promos launched in week two of January. This converts a scheduling failure into a fee-integrity failure. You will still be honoring that price in April, when you don't need it.

The deeper error is diagnostic. Owners read a soft January as a demand signal, when it is usually a capacity-use signal. Demand for dentistry in January is lower, yes. But it is not 25% lower in your hygiene column. It is lower by single digits, and the rest of the hole is unconfirmed appointments, December no-shows never rebooked, and a treatment-plan backlog nobody called.

Is Your January Drift or Erosion?

This is where our Drift vs. Erosion test earns its keep, because the same soft January means two completely different things depending on what the last three Januaries looked like.

It's drift if January runs predictably 8% to 12% below your annual average, year after year, and bounces back by March. Drift is small, steady and recoverable. You manage it operationally: pre-block the month in November, protect the hygiene schedule, run your short-call list hard, move elective and sedation cases out of December into the first three weeks of January where capacity is free. Drift costs you something, but it's a line item you plan around, like supply inflation.

It's erosion if January gets worse every year in relative terms, or if January collections hold flat while January net income falls. Erosion is structural and compounding, and it does not respond to better scheduling. The usual culprits: a PPO fee schedule that hasn't moved in four years while your clinical wages have, so every January visit is worth less than the one before it; a recall base that is shrinking because active patient count has been quietly declining; or a payer mix that drifted toward plans with the lowest maximums, so the reset hits harder each cycle. Those require renegotiation, repricing, or dropping a plan. They do not require a new morning huddle script.

Treating erosion as drift is the expensive mistake, and January is the single best month to catch it, because January is when a weak fee schedule and a thin recall base have nowhere to hide behind volume. Pull three years of January collections, three years of January active patient count, and three years of January net. If collections are flat and net is falling, you don't have a seasonality problem. You have a contract problem that seasonality is exposing.

The Six Weeks That Decide Q1

Everything that matters about January happens between mid-November and December 24. During those six weeks, two things are true at the same time: your patients are more motivated than they will be all year because their maximums are about to vanish, and your schedule is tighter than it will be all year. Most practices use that pressure to cram year-end cases in. Almost nobody uses it to sell the following month.

The move is to make January the overflow valve for December demand rather than the hangover from it. When a patient with a spent maximum wants a crown in December, you don't lose the case and you don't discount it. You book it for the second week of January, take the deductible at booking, and tell them plainly that their new maximum resets and this is the cheapest version of this treatment they will see. You have now converted the reset from an objection into a reason.

Do that fifteen times and a $10,000 hole closes. Fifteen cases at an average of $1,100 is $16,500 of January production that would otherwise have been a stack of unscheduled treatment plans.

We'd go further: we'd stop calling January a slow month internally. The language sets the expectation, the team schedules to the expectation, and the expectation produces the number. A practice that tells its front desk "January is always dead" has pre-authorized a dead January.

Do This Before the Holiday Schedule Locks

Pull your unscheduled treatment report this week and sort it by patients whose 2025 maximum is already spent, then call them with a January date and a dollar figure, not a question. Pre-block two restorative slots and four hygiene slots per day for the first three weeks of January now, before the December scramble eats them. Then pull three years of January collections, active patient count, and net income side by side and decide in writing whether you're looking at drift or erosion. If it's erosion, your Q1 project is a fee schedule, not a scheduling script.

What we're watching next: whether January softness shows up in supply, not just demand. Practices that limp through two bad first quarters tend to appear on the market in the spring, and we track every listing in the Practice Market Index. If Q1 listing volume starts running hot against the rest of the year, that tells us January isn't just a cash-flow nuisance, it's a decision point. The thing that would change our mind on all of this: if the data showed January patient counts falling while production per visit held or rose, that would mean practices are losing low-value visits and the month is less expensive than it looks. We don't think that's what's happening. We're checking.

If you want to know exactly what a soft month costs you, the number you need first is your fixed overhead per clinical day, because that's the figure that doesn't care about the calendar. Our free overhead calculator will give you that in about four minutes using figures already on your P&L, and it will show you where you sit against other practices at your collections level. Run your own numbers before you build the holiday schedule, not after.
