Dental Practice Overhead Benchmarks in Ohio (2026)

Take the average American general dentist's net income of $215,320 in 2025, set it against a practice collecting $950,000, and the implied overhead is 77.3%, not the 62% every benchmark table quotes. That is a $145,680 gap between what the benchmarks say an Ohio owner should be keeping and what the income data says they actually keep.

Here is our thesis, and plenty of Ohio owners will argue with it: if your overhead is running high, the problem is almost never your cost lines. It is your collections per operatory. Cutting supplies, renegotiating lab, squeezing staff hours: all of it moves the needle by a point or two while the real money sits in the four hours a day your fourth and fifth chairs are dark. Overhead is a fraction. Most Ohio owners spend an entire career attacking the top of it and never once touch the bottom.

The 62% Benchmark Describes a Practice You Probably Don't Own

The published targets are consistent. Overjet puts median overhead near 62% of collections, with 70-80% for practices under $750K, 60-70% in the $750K to $1.5M band, and below 60% above $1.5M. Dental Practice Insider sets the target range at 58-65% of gross collections and flags anything above 68% as a profitability problem.

Now run the arithmetic. At 62% overhead on $950,000 in collections, the owner's pre-tax take is $361,000. The ADA's national average net income for general practitioners is $215,320. Those two numbers cannot both describe the same typical practice. Either the median practice collects far less than $950,000, or the median practice runs overhead well north of 70%, or both.

Our read: the 58-65% range is a target that well-run, well-used practices hit. It is not a description of the field. If you are sitting at 71% and feeling like a failure because the internet says 62%, understand that the internet is quoting the top quartile back at you as if it were the middle. That does not make 71% acceptable. It means the path from 71% to 62% is longer and more structural than a supply catalog review.

The Ohio context matters for the denominator. In The Dental Signal Practice Market Index, built from practices currently listed for sale, median collections for general practices on the market run $946,000 (middle half $640,000 to $1,500,000, n=644), across a median of 5 operatories (n=754). That works out to a median of $200,000 collected per operatory (middle half $146,875 to $268,708, n=643). Those are asking-side practices, the ones whose owners have decided to sell, so treat them as a picture of what is changing hands and not as a portrait of every practice in the state. But the operatory spread is the number to sit with: the top of the middle half produces 83% more per chair than the bottom.

Where $950,000 Actually Goes in a Five-Operatory Ohio Practice

Apply the published line-item benchmarks to a $950,000 general practice and the picture gets uncomfortable fast. Dental Practice Insider's breakdown puts staff and payroll at 25-28%, lab fees at 7-10%, dental supplies at 5-7%, occupancy at 5-8%, and equipment and depreciation at 3-5%.

• Staff and payroll: $237,500 to $266,000
• Lab: $66,500 to $95,000
• Supplies: $47,500 to $66,500
• Occupancy: $47,500 to $76,000
• Equipment and depreciation: $28,500 to $47,500

Add the high end of every named line and you get $551,000, or 58% of collections. But the total benchmark tops out at 65%. So even at the worst case on all five named categories, there are 7 points of overhead, $66,500 a year, sitting in lines nobody put on the list: marketing, merchant fees, malpractice and business insurance, software subscriptions, accounting and legal, loan interest, continuing education, uniforms, waste disposal, the practice management system you renewed without reading.

That unnamed 7% is where we see the most recoverable money in the P&Ls we look at, because nothing in it is anyone's job. Payroll has a manager. Supplies have a rep. Nobody owns merchant fees.

What Most Owners Get Wrong: Cutting Supplies to Fix an Empty-Chair Problem

The specific mistake, and it is made overwhelmingly by owner-operators in the $750K to $1.2M band who have just had a bad quarter: they open the P&L, find the line with the most obvious fat, and cut it. Supplies is the usual victim because it is the one line where a single phone call produces a visible win.

Run both paths on our $950,000 practice. Path one: cut supplies 20%, from 6% of collections to 4.8%. That saves $11,400 and drops overhead from 62% to 60.8%.

Path two: lift collections per operatory from $190,000 to $215,000 across five chairs, which is still below the upper end of the Practice Market Index middle half. That is $1,075,000 in collections, up $125,000. Occupancy, equipment, debt service, insurance and most of your front-desk payroll do not move with that volume. Assume 35% variable cost on the incremental production, mostly lab, supplies and added hygiene hours: $43,750 of new cost, $81,250 of new profit. Overhead lands at 58.9%.

Seven times the money, and you did not fire anyone or switch bonding agents. Our view: for any practice under $1.5M, the supply-cut reflex is a rounding error dressed up as management. We would spend the same energy on a schedule audit and hit a harder number.

The exception is real and worth naming. If your chairs are genuinely full and your hygiene is booked six weeks out, then cost work is the only lever you have and you should run it hard. But most owners quoting a 71% overhead at us have a 4.2-operatory practice paying rent on 5 operatories.

7,442 Licensed Dentists and What Doctor Labor Costs in Ohio

Ohio is adding dentists. The Ohio State Dental Board reported 7,442 dentists licensed to practice in the state in FY23, up 5.1% from 7,082 in FY22. Licensure is not the same as practicing headcount, and it counts specialists and out-of-state licensees alongside your competitors down the road. But the direction is the signal, and a 5.1% one-year increase is not a rounding artifact.

On the cost side, BLS puts 3,560 general dentists employed in Ohio at an annual mean wage of $186,880 as of May 2023. That is your associate benchmark, and it is the single largest overhead line you will ever add in one signature. Load it with payroll taxes and benefits at roughly 15% and you are at $214,912 all-in. At a 30% of collections comp structure, that associate has to collect $622,933 just to cover their own number before they contribute a dollar to rent, staff or your income.

That is the test. If a prospective associate cannot realistically be handed $620,000 of collections inside eighteen months, hiring them does not reduce your overhead ratio. It raises it, and it raises it in the least reversible category on the statement.

Drift vs. Erosion: Which of Your Lines Is Which

This is where our Drift vs. Erosion framework earns its keep. Drift is small, steady and recoverable; you manage it operationally. Erosion is structural and compounding; it requires renegotiation, repricing or exit. The expensive mistake is treating erosion as drift.

The ADA's finding is the clearest case of erosion in the profession right now: over a recent five-year period, practice revenue rose 1.4% while practice expenses rose 4.9%. That is a 3.5-point annual wedge, and wedges compound. On our $950,000 practice, year one alone costs $15,561: expenses up $28,861 against revenue up $13,300.

Run it five years with no intervention and collections reach $1,018,389 while expenses reach $748,157. Profit falls from $361,000 to $270,232, and overhead climbs from 62% to 73.5%. You lost $90,768 a year of income without a single bad decision.

So classify your lines honestly. Supply price increases and a lab that raised crown fees 6% are drift: annoying, manageable, worth a phone call. Wages in a market adding 5.1% more licensed dentists a year, a PPO plan that has not moved its fee schedule since 2019, and a lease with fixed escalators against flat collections are erosion. Erosion does not respond to discipline. It responds to renegotiating the contract, repricing the service, or walking away from it.

Three Things to Do Before Friday

Pull your last twelve months of collections and divide by your operatory count, then compare that number against the $200,000 median and the $146,875 to $268,708 middle half in the Practice Market Index. If you are below $150,000 per chair, stop reading cost reports and go audit your schedule template and your hygiene recall list, because that is where your overhead ratio actually lives. Then pull every expense line that is not payroll, lab, supplies, occupancy or equipment, add them up, and confirm whether that unnamed bucket is closer to 4% or 9% of collections. Finally, pick the one PPO contract with the oldest fee schedule and put a renegotiation or termination date on the calendar, because a frozen schedule in a market adding dentists is erosion and it will not fix itself.

If you want the per-chair and per-line comparison done for you, run your practice through our overhead benchmarking tool and see exactly where your ratio breaks against the 58-65% target and against what Ohio practices are producing per operatory: run your own numbers.

What we are watching next: whether Ohio's licensed-dentist count keeps climbing at 5% a year in the next Dental Board report, and whether collections per operatory in the listing market holds at $200,000 or starts sliding. If per-chair production falls while headcount keeps rising, the 62% benchmark stops being a target and becomes a memory, and the whole conversation moves from cost control to capacity and contract exits. We would change our view on cost-cutting if we saw supply and lab inflation outrun wage inflation for two consecutive years. So far it has not.
