Inside the Data: Why Production Is Flat and Profit Is Shrinking
National survey data shows flat production and rising overhead. Where the margin goes, line by line, and what to do about it this week.
An earlier version of this issue was titled for 500+ calculator runs and described fourteen operator submissions and usage patterns. Our records do not support those counts, so we removed them along with every statement that relied on them. The analysis rests on the published sources cited throughout.
Comparing the five years before 2020 to the five years after, dentist revenue slipped 1.2% while practice costs climbed 3%, and net income per dentist fell 13.2%, from $230,353 to roughly $200,000, according to Dental Economics' reading of ADA Health Policy Institute data. A one percent revenue dip took thirteen percent of the profit, and dentists worked more hours to get the smaller number.
Here's the part most owners won't like: that gap is not a cost-control failure, and you will not close it with an expense audit. The squeeze is a yield problem. An hour of your chair time stopped keeping pace with the price of everything the practice buys, and the overhead percentage you've been managing to is a lagging summary of that fact, not a lever on it. Our view: if you spend Q4 renegotiating supply contracts and trimming payroll a point, you'll recover maybe a sixth of what you lost and still be flat next year.
A 1.2% Revenue Dip Ate 13% of the Profit
Start with why the arithmetic is so brutal. Profit is a thin residual sitting on top of a large, mostly fixed cost base. When the top line is flat and the base inflates, the residual absorbs the entire difference. ADA News, reporting Health Policy Institute figures, lays out the same pattern: revenue down 1.2%, costs up 3%, weekly hours worked up from about 35 to 36 or more, and general practitioner net income landing near $208,000. Different cuts of the data land on slightly different income numbers, but every cut points the same direction.
For the current baseline, the ADA's 2025 Survey of Dental Practice puts average net income for general dentists at $215,320 and average gross billings per general dentist at $965,660. That's the scoreboard. Roughly a million dollars of billings per doctor, and a bit over two hundred thousand dollars of it reaching the owner, after working a longer week than dentists worked a decade ago.
Now the question nobody wants to answer out loud: if production per dentist is flat in nominal dollars, it has fallen hard in real dollars. Staff wages, lab fees, rent, and software did not hold still for five years. Flat is not flat. Flat is a decline you can't see on the P&L because the P&L is denominated in a currency that moved.
