What is a good profit margin for a dental practice?
A healthy general dental practice keeps 35 to 45 percent of collections for the owner (pre-tax profit plus owner pay). That is a Sorso estimate: it is what remains after the 55 to 65 percent overhead range ZenOne cites from Overjet's 2025 data, and Overjet's national median overhead of about 62 percent leaves about 38 percent. Pay the owner a market salary for the dentistry and the normalized EBITDA margin is lower, and it rises with practice size.

Definition
Dental practice profit margin is the percentage of collections retained as owner income after operating expenses; normalized EBITDA margin removes owner above-market compensation to show comparable enterprise profitability.
The detail
Dental profit margins are commonly reported two ways and the difference matters. Owner margin is collections minus operating expenses with the owner's pay left in, and because the usual overhead benchmarks exclude owner dentist compensation, it is simply 100 percent minus overhead. ZenOne cites Overjet's 2025 data for total overhead of 55 to 65 percent of collections and a national median of about 62 percent, which puts owner margin at 35 to 45 percent, and about 38 percent at the median (Sorso arithmetic). ZenOne also reports that Blue & Co., a dental CPA firm, found a 39 percent margin before debt service for its top-performing group in 2025, and warns that margin and overhead are not always exact opposites because definitions differ. Normalized EBITDA then takes out a market salary for the owner's clinical work. As a worked example, a practice collecting $1 million at the 62 percent median overhead keeps $380,000; paying the owner the BLS May 2025 median wage for dentists, $176,110, leaves about $204,000, a normalized margin of about 20 percent. At $1.5 million of collections the same arithmetic gives about 26 percent, which is why normalized margins rise with size. No public source we could open publishes margins for orthodontics, pediatric dentistry or oral surgery, so we do not quote them. ZenOne's category ranges are staff 25 to 30 percent of collections, lab fees 6 to 8 percent, clinical supplies 4 to 6 percent, facility 6 to 10 percent and marketing 4 to 7 percent. Practices outside these bands usually have a specific, fixable issue, and finding which one is what a dental practice accountant who reports lab, supply and hygiene ratios every month is for. For hygiene, the usual consultant benchmark is 30 to 33 percent of total production.
| Measure | Figure | Source |
|---|---|---|
| Total overhead | 55% to 65% of collections | ZenOne, citing Overjet (2025) |
| National median overhead | About 62% | ZenOne, citing Overjet (2025) |
| Owner margin (profit plus owner pay) | 35% to 45%; about 38% at the median | Sorso estimate: 100% minus overhead |
| Top-performing group | 39% margin before debt service | Blue & Co. (2025), via ZenOne |
| Normalized EBITDA margin, $1M collections | About 20% | Sorso estimate: 38% of collections minus a $176,110 BLS median dentist wage |
| Normalized EBITDA margin, $1.5M collections | About 26% | Sorso estimate: same method |
| Hygiene share of total production | 30% to 33% | DentistryIQ (2018) |
Overhead here excludes owner dentist pay, so owner margin is its complement. ZenOne cautions that margin and overhead are not always exact opposites because income definitions, doctor pay and debt treatment differ. ZenOne's category ranges: staff 25 to 30 percent, lab fees 6 to 8 percent, clinical supplies 4 to 6 percent, facility 6 to 10 percent, marketing 4 to 7 percent of collections.
Total dental overhead typically runs 55 to 65 percent of collections, usually before owner dentist pay; Overjet put the 2025 national median at about 62 percent.

What this means for clinic owners
From Sorso
Profit margin tells you whether your practice is healthy. Hygiene production tells you whether it will stay healthy. Track both monthly. The two together explain almost everything that goes right or wrong in a dental practice.

What is the average EBITDA multiple for dental practices?
FOCUS Investment Banking publishes a ladder by adjusted EBITDA with the buyer type named on each rung: under $1M at 5–7×, $1M to $3M at 7–9×, $3M to $5M at 9–11×, and $5M+ at 10–12× in select cases. McLerran & Associates puts platform-grade groups above $5M in adjusted EBITDA at 10x to 12x or more and leaves its lower tiers unnumbered. Neither firm publishes an absolute multiple for orthodontics, oral surgery or pediatric dentistry; McLerran says only that specialty practices run roughly 1 to 3 additional turns of EBITDA above general dentistry at the same size tier. Scale, not clinical quality, is what moves you up the ladder.
What are EBITDA add-backs in practice valuation?
EBITDA add-backs are non-recurring or owner-related expenses added back to reported EBITDA to show normalized earnings, the figure a buyer applies its multiple to. In an owner-operated practice they usually cover above-market owner pay, personal expenses run through the business, one-time costs and pro forma adjustments, and each one needs documents to survive a buyer's diligence.
What is a good overhead ratio for medical practices?
A good overhead ratio depends on the specialty: 55 to 65 percent of collections in general dentistry, with a national median near 62 percent (ZenOne, citing Overjet's 2025 data), 72.9 percent of net revenue in medical dermatology and 75.1 percent in cosmetic (FTI Consulting), and 80.8 percent in outpatient physical therapy (U.S. Physical Therapy's FY2025 10-K). An 80.8 percent ratio is normal in physical therapy and would be far too high in dentistry, which is why a single cross-specialty target is worse than none.
What is the average revenue per provider?
There is no single average: revenue per provider depends on specialty, and the one broad survey that reports it, MGMA's, is a paid product. The published figures you can check are narrower. FTI Consulting's 2019 benchmarks put median revenue per FTE physician at $1.3 million in medical dermatology and $1.8 million in cosmetic dermatology, and in a Sorso calculation from CMS's 2024 provider-level data the median ophthalmologist received $167,145 in Medicare payments and the median orthopedic surgeon $96,684, from Medicare alone.
How much does a dental practice owner make?
A general dentist who owns a practice earned $228,980 on average in 2025 and $199,140 at the median, according to the ADA Health Policy Institute's Survey of Dental Practice. Specialist owners averaged $372,460 (median $259,550). Employed general dentists averaged $164,510, so on these figures owning a practice added about $64,000 a year on average and about $34,000 at the median.
