Dental Practice Overhead Benchmarks in Missouri (2026)

The average general dentist in this country now spends $482,343 to collect $698,436. That residual, $216,093, is the owner's entire income from the practice, and it is shrinking from both ends: ADA Health Policy Institute data show average expenses per GP up 3.0% while average revenue fell 1.2% over the same pooled period. Run the ratio and the average American general practice is operating at roughly 69% overhead.

Here is the claim plenty of Missouri owners will want to argue with: the 62% overhead benchmark you have been graded against for a decade is a failing grade in this state, not a passing one. A Missouri general practice should be targeting 57 to 60 percent, and an owner sitting at 62 and calling it "industry average" is already two years into a problem they have not named yet. The reason is specific to Missouri, and it shows up in the wage data before it shows up in the P&L.

Missouri Prices Its Dentists 16% Above the National Floor

The federal baseline is clear. BLS puts the national median annual wage for dentists at $176,110 (May 2025), across 161,400 dentists, with 6% projected employment growth from 2025 to 2035. Missouri does not sit at that number. O*NET, using BLS 2025 wage data for Dentists, General in Missouri, puts the state median at $204,960, with a 10th percentile of $95,610 and a 90th of $427,970.

That is $28,850 above the national median, or 16.4% higher. It matters for two reasons, and neither is the obvious one.

First, it sets the price of an associate. If you hire in Missouri, the market clearing number for a competent general dentist is anchored near $204,960, not near $176,110. Load payroll taxes and benefits at a conservative 18% and the true cost of that associate is $241,853 before you have bought a single bur.

Second, it sets the price of the owner's own labor. Overhead ratios are only honest if you price your clinical time at market. An owner who works four days a week producing dentistry and takes the residual as "profit" is quietly counting $204,960 of wage as a return on capital. Strip that out of a practice collecting $950,000 and the honest owner-return is a lot thinner than the tax return suggests.

The Missouri wage premium is not a reason to accept higher overhead. It is a reason to demand lower overhead everywhere else, because the labor line is the one you have the least room to cut.

Three Benchmark Sets, Three Different Answers, and Why the Gap Is the Signal

Owners get confused here, and the confusion is expensive. Three credible sources give three different targets:

• Dental CPA USA cites ADA News putting industry-wide overhead at "around 62%" of production, with staff costs at 22 to 26% of collections, supplies at 5 to 8%, lab at 10 to 15%, facility at 7 to 9%, and total variable costs (payroll plus lab plus supplies) at 45 to 55%.
• Dental Strategy Institute's 2026 percentile data puts the median total overhead ratio at 57 to 60%, the 75th percentile at 64 to 67%, and the 90th at 72% or worse. Their category medians: occupancy 6 to 7%, clinical supplies 5 to 6%, lab 7 to 8%, marketing 2 to 3%.
• The ADA HPI revenue and expense figures imply about 69%.

These are not contradictions. They are different denominators and different treatments of owner compensation. "62% of production" is a softer number than "62% of collections" in any practice with a 5% adjustment-and-write-off gap, because production is the bigger denominator. And the ADA's 69% is a pooled national average that includes the tail of struggling practices, not a target.

Our view: benchmark against percentiles, not averages. An average tells you where the middle of a distribution that includes failing practices sits. A percentile tells you where you rank. If you are at 64 to 67% total overhead you are not "about average," you are in the bottom quartile of operators, and the difference between that and the median is real money.

What Most Owners Get Wrong: Grading the Total Instead of the Six Lines

The mistake is almost universal among owner-operators who do their own monthly review, and it goes like this. They pull the P&L, divide total expenses by collections, get 61%, decide they are fine, and close the file. Total overhead is the one number that tells you the least, because it hides offsetting errors.

A practice can hit 61% total while running lab at 13% and staff at 21%. That looks acceptable. It is not. Lab at 13% against a median of 7 to 8% means either the fee schedule on crown-and-bridge is underpriced, the case mix has drifted toward high-lab-cost dentistry at flat fees, or nobody has renegotiated the lab contract in four years. Staff at 21% against a 22 to 26% band usually means the practice is understaffed and the owner is absorbing admin work at $204,960-an-hour clinical time. Those two errors cancel in the total and compound in reality.

The six categories are the diagnostic. The total is just the receipt.

Three Frozen Fee Years Turn a $9,120 Raise Into a $28,473 Hole

Take a Missouri general practice collecting $950,000. Staff costs at 24% of collections run $228,000. The team gets a 4% raise, which in this labor market is not generous, it is defensive. That is $9,120 of new cost.

If collections grow 4% too, nothing has happened. Staff stays at 24%, the ratio holds, and the owner absorbs the raise out of new revenue. That is Drift vs. Erosion resolving in your favor: a small, steady cost increase matched by a small, steady revenue increase. You manage it operationally and move on.

Now freeze the fee schedules. Three PPO plans, no increase, three years running, which is the normal experience and not a worst case. Staff costs compound: $228,000 becomes $256,473 by year three. Collections stay at $950,000. The staff ratio moves from 24.0% to 27.0%. Three points of overhead, $28,473 out of the owner's pocket, with no decision ever made and no line item that looks alarming in any single month.

That is erosion, not drift, and the tell is the frozen denominator. Drift is a cost rising inside a system that can absorb it. Erosion is a cost rising against a revenue line that structurally cannot move. The first one you manage. The second one requires renegotiation, repricing, or dropping the plan, and treating it as drift is how a 59% practice becomes a 64% practice in thirty-six months without anyone noticing.

We'd renegotiate or drop. An owner who has absorbed three years of frozen fees and calls it a staffing problem is solving the wrong equation.

Five Operatories, $61,750 of Rent, and the Capacity Nobody Uses

Occupancy is the line owners treat as fixed and therefore ignore. At the 6 to 7% median, our $950,000 Missouri practice is paying roughly $61,750 a year for space.

Look at the physical plant. The Dental Signal Practice Market Index, built from dental practice broker listings, shows a median of 5 operatories among practices currently listed for sale (n=754), with the middle half between 4 and 7. Median collections per operatory among those same listings run $200,000, with the middle half between $146,875 and $268,708 (n=643). These describe the asking side of the market, practices whose owners have decided to sell, not the typical practice in Missouri or anywhere else. But they are a real distribution of real physical plants, and the capacity math is the same wherever you sit.

A five-operatory practice collecting $950,000 is running $190,000 per operatory, below that $200,000 median. That is $61,750 of rent divided across 5 rooms, or $12,350 per room per year. If two of those rooms are dark three days a week, the practice is paying roughly $10,586 a year for capacity it has chosen not to staff.

That is not an argument to break the lease. It is an argument that occupancy is a variable cost wearing a fixed cost's clothing, and the variable you control is use, not rent. Adding a hygiene day into a dark room moves collections without moving occupancy at all, which is the only kind of growth that improves the overhead ratio by arithmetic rather than by effort.

Our Call on the Missouri Number

For a Missouri general practice collecting between $700,000 and $1.2 million, we'd set the target at 58% total overhead with the six categories held individually: staff 24 to 26, occupancy 6 to 7, clinical supplies 5 to 6, lab 7 to 9, marketing 2 to 3, and everything else inside 6.

The staff band runs at the top of the national range on purpose. Missouri's wage premium is real and it is not going to reverse in a labor market with 6% projected national growth in dentist employment and a hygiene market tighter than that. Trying to hold Missouri staff costs at 22% is how practices lose their best assistants to the group down the road and then pay a recruiter to replace them.

Buy the wage premium. Pay for it out of lab, supplies, and use, where the median operator is leaving three to five points on the table. That is the trade, and owners who refuse to make it end up with 62% overhead and a turnover problem instead of 58% overhead and a team.

What Would Change Our Mind

Two things we're watching into 2027. First, whether the ADA's expense-outrunning-revenue trend holds or breaks: if national expenses keep climbing 3% against flat revenue for another cycle, a 58% target stops being demanding and starts being fictional, and the honest advice shifts from cost control to fee repricing and payer mix. Second, whether the Missouri wage premium spreads down the org chart. The dentist number is documented. If assistant and hygiene wages in this state move the same 16% above national norms, the 24 to 26% staff band is wrong and we'll say so. We are also watching whether practices listing for sale keep clustering at five operatories, because a shift toward larger physical plants would change the occupancy math for everyone buying.

Do This Before Your Next P&L Close

Pull twelve months of expenses and split them into the six categories, not four, not three. Calculate each one as a percentage of collections, not production, and write the percentile band next to each. Then for every category outside its band, ask one question: is the denominator frozen? If your fee schedules have not moved in three years, you are looking at erosion and no amount of supply-ordering discipline will fix it.

If you want the fast version of that exercise, put your collections and your six expense categories into our overhead benchmark tool and see where you land against the percentile bands rather than against an average that includes practices you would never want to own. It takes about six minutes and it will tell you which of the six lines is actually costing you money. Run your own numbers.
