Dental Practice Overhead Benchmarks in Tennessee (2026)

The average general practice in the country billed $965,660 last year and handed its owner $215,320. Everything in between, all $750,340 of it, is what we call overhead, and most owners can't tell you within five points what share of collections it eats. Those are national figures from the ADA Health Policy Institute's 2025 Survey of Dental Practice, and they work out to roughly 78% of gross billings consumed before the owner's draw is separated out.

Here's the line we want you to sit with: you don't have an overhead problem, you have an empty-chair problem wearing an overhead costume.

Our position, and plenty of Tennessee owners will argue with it: if you're collecting under $1 million, the 62% benchmark is the wrong target, and every quarter you spend chasing it with cuts is a quarter you didn't spend filling the fifth operatory you already pay rent on. The percentage is an output. Treating it as an input is how practices shrink their way to a better-looking ratio and a worse-looking paycheck.

The Benchmark Range That Actually Applies in Tennessee

Start with the honest range. National median overhead sits around 62% of collections, but Overjet's breakdown by practice size puts practices under $750K in collections at 70% to 80%, and multi-location groups above $1.5M at 50% to 55%. That spread of 25 to 30 points isn't noise. It's fixed cost divided by different denominators.

Tennessee sits in a specific spot inside that. According to BLS Occupational Employment and Wage Statistics for Tennessee (May 2023), the state employed 1,450 general dentists at a mean annual wage of $164,410, with a median hourly wage of $72.22. That's your doctor-labor baseline, and it matters more than any supply-cost table you'll find. If you bring in an associate four days a week at the state median rate, 32 hours a week across 48 weeks, you've committed about $110,930 before benefits. On $950,000 in collections, that single line is 11.7% of overhead all by itself.

Tennessee's advantage is on the property side: rent, buildout and utilities generally run cheaper here than in the coastal metros that pull the national averages upward. Tennessee's disadvantage is that clinical wages have converged toward national levels while fee schedules have not. That combination is why a well-run Middle Tennessee general practice can land in the low 60s while a Memphis or Knoxville practice with the same collections and a heavy PPO mix sits at 72% and cannot explain why.

What Most Owners Get Wrong: Ranking Staffing Separately From Overhead

The ADA Health Policy Institute's Q4 2024 Economic Outlook asked 728 dentists to name their top-three challenges heading into 2025. Staffing came first at 62.2%. Insurance reimbursement came second at 57.7%. Rising expenses and overhead came third at 45.7%.

Read that again as a bookkeeping statement and it falls apart. Staffing is not a challenge alongside overhead. Staffing is the largest single component of overhead, usually 25% to 30% of collections once you load in payroll taxes and benefits. Reimbursement isn't separate either: it sets the denominator that every overhead percentage is measured against. Owners are ranking the same problem three times and then treating "overhead" as the leftover bucket of supplies, lab and sundries.

That's the specific mistake, and it's made most often by the owner-operator producing four days a week with an office manager handling the books. They open the P&L, see supplies at 7.4% against a 5% benchmark, and start a vendor consolidation project that will recover a point and a half at best. Meanwhile the hygiene schedule is running at 68% capacity and the fifth operatory has been a storage room since 2023. The vendor project is visible, finite and satisfying. The schedule problem is chronic, political and worth ten times more.

Running the Numbers on a Five-Op Tennessee Practice

Take a general practice in Chattanooga: five operatories, $950,000 in collections, overhead at 74%. That's $703,000 in expenses and $247,000 left for the owner.

Path one is the vendor project. Push supplies from 7.0% of collections down to 5.5% with a consolidated ordering program and tighter inventory control. That's 1.5% of $950,000, or $14,250 a year. Overhead falls from 74% to 72.5%. Real money, and we'd take it. It's also a one-time recovery that takes six months of somebody's attention.

Path two is the fifth operatory. Open one additional hygiene day a week and produce $1,300 on it. Across 48 weeks that's $62,400 in new production. The variable cost: a hygienist at $42 an hour fully loaded for eight hours, 48 times, is $16,128. Add supplies and lab at 8% of the new production, another $4,992. Total added cost of $21,120.

New net from that day: $41,280. Collections go to $1,012,400, overhead dollars go to $724,120, and the percentage drops to 71.5% without a single vendor call.

The schedule move is worth 2.9 times the supply squeeze. Do both and you're at 70.1% overhead with about $302,530 in owner earnings. Note which lever moved the percentage more while also moving the dollars. Rent, front-desk salaries, software, insurance and debt service did not change at all in path two. That's the entire mechanism: fixed cost spread over a larger base.

Drift vs. Erosion in the Wage and Supply Lines

Not every rising cost deserves the same response, which is why we use Drift vs. Erosion. Drift is small, steady, recoverable, and you manage it operationally. Erosion is structural and compounding, and it requires renegotiation, repricing or exit. Treating erosion as drift is the expensive mistake.

The 2025 Dental Economics-Levin Group Annual Practice Survey found 58% of practices reported higher overhead in 2025 than 2024, with an average increase of 4.5%. That 4.5% is drift. You absorb it with a fee update, a tighter schedule, a supply audit. It's annoying and it's manageable.

The same survey found 27% of practices reported overhead up more than 10%. That is not drift. A 10-point jump in a single year means something structural broke: a wage reset you matched without changing fees, a lease renewal at market, a payer mix that tipped toward your worst contract, or a hygiene vacancy you filled with a temp agency at 1.6 times the loaded rate. Owners in that 27% who respond with a supply audit are bringing a dustpan to a plumbing failure.

The test is simple. If the increase is under 5% and spread across several line items, manage it. If it's concentrated in one or two lines and will not reverse on its own, you're renegotiating a contract, repricing a fee schedule, or leaving something behind. Our view: most owners misclassify at least one erosion event per cycle as drift, and the wage line is usually the one they get wrong.

Collections Per Operatory Is the Number We'd Put on the Wall

Overhead percentage tells you what happened. Production density tells you what's possible. In the Practice Market Index, our dataset built from dental practice broker listings, the median practice on the market runs $200,000 in collections per operatory, with the middle half between $146,875 and $268,708 (n=643). Median operatory count is 5 (n=754). These describe practices listed for sale, the asking side of the market, not all practices, but they're a usable yardstick for the physical plant you're paying for every month.

Tennessee listings skew larger than the national set: median collections of $1,037,500 for Tennessee practices on the market (middle half $758,000 to $1,800,000, n=36) against a national listed median of $957,588 (n=753). The practical read: in Tennessee, a five-op general practice collecting $950,000 is at $190,000 per operatory, which is under the median density. You're paying rent, utilities and buildout amortization on capacity you aren't using, and that unused capacity shows up on your P&L as a high overhead percentage.

If you're at $130,000 per operatory, no cost-cutting program on earth will get you to 62%. You're carrying too much room. If you're above $260,000 per operatory and still over 70%, the problem isn't capacity, it's your fee schedule or your payroll structure, and that's a different conversation entirely.

What Would Change Our Mind

The case against our position is labor. If Tennessee hygiene and assistant wages keep converging on national levels while PPO fee schedules stay flat, the fill-the-chair argument weakens, because the marginal day gets more expensive every year while its revenue doesn't move. We're watching two things through 2026: whether the 27% of practices reporting double-digit overhead increases shrinks or holds, and whether Tennessee wage growth for clinical staff outpaces the fee updates practices are actually getting from their three largest payers. If the marginal hygiene day stops clearing $40,000 a year in contribution, the math flips toward repricing and contract exits, and we'll say so.

Do This Before Friday

Pull your last 12 months of collections and divide by your operatory count, then write that number where you'll see it daily. Pull the same 12 months of total expenses excluding owner compensation, divide by collections, and label each line as drift or erosion with a dollar figure next to it. Then look at your hygiene schedule for the next three weeks and count the open columns, because that's the only overhead lever that pays twice. If the density number is under $150,000 per operatory, stop the vendor project and fix the schedule first.

If you want to see where your practice actually sits against these ranges instead of guessing, run your own numbers through our free overhead calculator. It takes your collections, your operatory count and your major expense lines and gives you back your overhead percentage, your collections per operatory, and which category of practice your cost structure resembles. The more Tennessee owners who run it, the sharper the state-level benchmarks we can publish back to you.
