How to analyze a dental practice location before you call a broker

To analyze a dental practice location, draw a realistic trade area around the site (about 5 miles, or a 10 to 15 minute drive, in the suburbs), count the active general practices inside it from a list checked by a person, and divide the residents by that count. Then compare the result with real benchmarks: in suburban and urban America, the median ZIP has 3,391 residents per general practice within 5 miles, the top quarter has more than 4,628, and the most crowded tenth has fewer than 2,101. Finally, check whether the people fit your practice: income, age, children and growth. Do all of this before you talk to a broker, so the broker works from your shortlist instead of theirs.

The benchmarks on this page come from Dentagraphics' October 2026 study of verified practices, which counted the 88,367 active general practices (of 118,330 practices verified by hand) within 5 miles of every populated ZIP code in the US.

What you won't get from an instant report. An automated report can describe one address. It can't tell you where other dentists are already looking, whether the offices nearby actually exist, or whether a busy market is still open. Dentagraphics can: 118,330 practices verified by hand, 12 years of research from more than 10,000 paid customers, and custom reports with handwritten analysis by a demographer.

The method, step by step

1. Write down your practice model first

General or specialty, fee-for-service or PPO or Medicaid, families or older adults, how many operatories. Every number below means something different depending on the model. A high-income area suits a fee-for-service office; a high-volume insurance practice can work with less income and more people.

2. Draw the trade area

Site type	Typical trade area
Suburban	About 5 miles, or a 10 to 15 minute drive
Dense urban	Often 1 to 2 miles
Rural town	The town and the area that shops there, often wider than 5 miles

Use the same area for every site you compare. A 3-mile ring next to a 10-mile ring tells you nothing.

3. Count the practices that actually compete

Count active general practices, not licensed dentists. Remove closed and moved offices, merge duplicates, and count specialists separately. Online maps get this wrong in both directions. Dentagraphics checks every practice by hand and rechecks each one every year. See how we verify practice data.

4. Divide residents by practices, and compare with benchmarks

Residents per general practice within 5 miles of a ZIP's population center, October 2026:

Where	Most crowded 10%	25th percentile	Median	75th percentile	Least crowded 10%
Urban ZIPs (3,000+ people per sq mi)	under 2,042	2,467	3,185	4,362	over 5,867
Suburban ZIPs (500 to 2,999 per sq mi)	under 2,155	2,704	3,534	4,816	over 7,016
Suburban and urban combined	under 2,101	2,587	3,391	4,628	over 6,429

Source: Dentagraphics national saturation study, October 2026. 88,367 hand-verified active general practices; Census ACS-based population.

How to read your number:

Your area's residents per general practice	What it suggests
Over 4,628	Top quarter of suburban and urban ZIPs. Room on paper; now confirm the residents can become patients
3,391 to 4,628	Above the median. Workable for most models if income and age fit
2,101 to 3,391	Below the median. A new office has to win patients from established ones
Under 2,101	The most crowded tenth. Buying an existing practice is often the safer route

The national average is 3,860 residents per general practice. Rural areas need different rules: more than half of rural ZIPs (52.7%) have no general practice within 5 miles, because rural patients routinely drive farther.

5. Check whether the residents fit your practice

A ratio is only room if the residents can become your patients. What the study found about each factor:

Factor	What the national data shows	What to do with it
Household income	The richest tenth of suburban and urban ZIPs has 2,380 residents per practice; the poorest tenth has 4,828	Treat high income as a reason to look harder at competition, not as proof of demand
Children	ZIPs with the most children (26.9% or more under 18) have 4,319 residents per practice, 37% more than ZIPs with the fewest (3,157)	Family areas are often under-served; strong for family and pediatric models
Older adults	The oldest tenth of ZIPs has 3,051 residents per practice vs 3,968 in the youngest	Older areas tend to be crowded; check whether your services fit their needs
Growth since 2020	Every growth tenth falls between 3,259 and 3,658 residents per practice	Growth alone doesn't mean room. Dentists have largely kept pace

6. Compare sites, not cities

Inside one metro the gaps are wide. In the Chicago metro, the least crowded tenth of ZIPs has 4.1 times as many residents per practice as the most crowded tenth (7,488 vs 1,840). Even neighboring ZIPs differ: about one in seven pairs of suburban or urban ZIPs within 5 miles of each other differ by 50% or more. Run every candidate site through the same steps.

7. Then call a broker, with a shortlist

Bring the broker two or three trade areas that passed the steps above and ask for spaces inside them.

Worked example: 5300 Glick Road, Dublin, Ohio

Our sample Single-Site Study evaluates this address for a general dental startup. The report's numbers:

	Ohio	15 min drive	10 min drive	5 min drive
Residents	11,925,796	139,738	57,911	8,601
Dental offices	2,676	48	21	2
Residents per dental office	4,457	2,911	2,758	4,301
Median household income	$72,212	$128,947	$165,593	$176,898
Population growth, 2020 to 2025	1.07%	6.67%	9.01%	9.39%

The 3-mile ring holds 61,975 residents and 12 dental offices, or 5,165 residents per office.

How to read it with the benchmarks. The report counts dental offices by drive time and radius; the benchmarks count general practices within 5 miles of a ZIP center, so treat the comparison as a guide, not an exact match.

Competition. At 5,165 residents per office within 3 miles, the site sits above the top-quarter line for suburban ZIPs (4,816). The 10 and 15 minute drive times (2,758 and 2,911) are tighter, around the suburban 25th percentile, which is why the drive-time view matters.
Income. A median household income of $176,898 within a 5 minute drive is in the richest tenth of US suburban and urban ZIPs. Nationally, that tenth is the most crowded group of all, with a median of 2,380 residents per practice. This site has far more room than its income bracket usually does. That's the finding that makes it interesting.
Growth. 9.01% growth within 10 minutes since 2020, against 1.07% for Ohio. Growth doesn't usually mean room, but here it comes with room.
Verdict. The report rates it an above-average to strong market for a general dental office, while noting that parking, visibility, signage and access still need a look at the property itself.

The data points that matter, and the ones that mislead

Matters	Misleads
Residents per verified general practice in your trade area	Practice counts from online maps, which include closed, moved and duplicate listings
The same radius or drive time for every site	A city or county average, which hides gaps of roughly 2 to 5 times between ZIPs in one large metro
Income, read alongside competition	Income on its own: the richest areas are the most crowded
Children and age mix that fit your model	Population growth on its own: growing areas are about as crowded as the rest
Your area compared with nearby areas	A national average applied everywhere, without the 2,000 floor or local comparison
Who prepared the numbers and how old they are	Demographics supplied by someone paid when the deal closes

Red flags

Fewer than 2,000 residents per general practice in your trade area. That's below the floor; nationally, under about 2,100 is the most crowded tenth of suburban and urban ZIPs.
High income with low residents per practice. Common, and it means every new patient comes from someone else's chair.
A competitor count you can't trace to a list checked by a person.
Only one radius shown. Ask for drive times too; the Dublin example shows how much they can differ.
Growth used as the whole argument. Since 2020, the fastest-growing tenth of ZIPs has only about 7% more residents per practice than the fastest-shrinking tenth.
A lease with no exclusivity clause in a building that could take another dentist.

Why do this before you call a broker?

A broker is useful for finding and negotiating a space or a practice. But a broker is usually paid when a lease is signed or a sale closes. That doesn't make their numbers wrong. It means the question "is this the right market?" should be answered by someone with no stake in the answer.

Dentagraphics does not broker practices, does not lease space and holds no stake in any location. We are paid for the analysis, not for the deal. See who can help you start a dental practice for the full team, in order.

Frequently asked questions

How do I analyze a location for a dental practice? Draw a trade area (about 5 miles or a 10 to 15 minute drive in the suburbs), count verified active general practices inside it, and divide residents by practices. Compare the result with benchmarks: in suburban and urban ZIPs the median is 3,391 residents per general practice within 5 miles, and the top quarter has more than 4,628. Then check income, age, children and growth against your practice model.

What demographics matter for a dental practice location? Residents per verified general practice first, then household income, age mix, share of children, insurance mix and growth. Read income alongside competition: the richest tenth of suburban and urban ZIPs has 2,380 residents per practice, about half the 4,828 in the poorest tenth. Areas with many children have 37% more residents per practice than areas with few.

How many people does a dental practice need? Use no fewer than 2,000 residents per general practice as the floor. The US average is 3,860 residents per general practice. In suburban and urban ZIPs, the middle of the range is 3,391 within 5 miles, and anything over 4,628 is in the top quarter. A fee-for-service practice in a high-income area can work with fewer residents than a high-volume insurance practice.

Should I talk to a broker before choosing a location? Talk to a broker after you have a shortlist. A broker is usually paid when a lease is signed or a sale closes, so get the market analysis from someone with no stake in where you open, then give the broker two or three trade areas to search.

Who can analyze a dental practice location for me? Dentagraphics. A Single-Site Study ($695) examines one address with handwritten analysis by a demographer, human-verified competition data and a 30-minute call. An Area Analysis ($745) compares many areas at once to find room for another practice. Dentagraphics has no stake in any location. See who can help you start a dental practice.

Can I do this myself? Yes. A Start/Buy membership ($149 per month) gives you unlimited address and area searches with verified practice counts. Have a dental real estate attorney review the lease before you sign; Dentagraphics offers lease review by a dental real estate attorney.
