Dental Lab Fees and Their Effect on Procedure Margin

Figures are industry benchmarks for directional guidance, not accounting advice. Validate against your own records.
Laboratory fees are one of the larger variable costs in a general practice, commonly cited at about 6 to 8 percent of collections, with figures above 10 percent treated as high. What makes lab fees worth a closer look is not the size of the total but the shape of it: the cost does not spread evenly across the schedule, it lands hard on a small number of codes.
Lab cost is lumpy, not average
A crown, a bridge, or a denture carries a real laboratory bill. A recall exam, a cleaning, or many simple restorative procedures carry none. Averaged across everything, lab fees look like a modest single-digit percentage. Seen procedure by procedure, they are concentrated, and the procedures that carry them are not always the ones with the most room in the fee.
Fold lab into loaded cost, per code
To know the margin on a restorative procedure, attach its actual lab bill to that specific code rather than a practice-wide average, then add the chair time, materials, and a share of overhead. Only then does the margin reflect what the procedure really costs. A crown and a filling billed at very different fees can end up closer in margin than they look once the lab bill is on the crown.
Why the average misleads
Spreading a single lab percentage across every procedure overstates the margin on lab-heavy work and understates it everywhere else. That is the opposite of what you want, because the lab-heavy procedures are exactly the ones where a thin margin matters most. The average is a category check. The per-code figure is a decision.
Levers once you can see it
With lab cost visible per procedure, the usual levers apply: tighten case and remake management, review vendor selection, or revisit the fee or the time on the procedures where the lab bill leaves little behind. DentistOpFlow attaches these costs automatically from your own invoices, and the same reasoning works by hand: put the real lab cost on the real procedure before you judge its margin.
