Dental practice site selection: how to choose a location, and what data to use

Choosing where to open, buy or relocate a dental practice comes down to one question: will enough of the right patients choose this office over the ones already nearby? Everything below is a way to answer that with evidence instead of a drive-by or a realtor's opinion.

The five numbers that decide a dental location

Population within your service area. Usually measured by drive time (for example 5, 10 and 15 minutes) or by radius. Drive time is more honest in suburbs and rural areas, where a 3-mile circle can cross a river or a highway nobody crosses to see a dentist.
Residents per dental office. Population divided by the number of practices in the same area. This is the single most useful saturation measure. Compare it with the county and state averages, not an absolute rule of thumb.
Household income and insurance mix. Income drives case acceptance and fee-for-service potential. The share of residents on public insurance shapes which practice model works.
Age profile and household makeup. Young families mean pediatric and orthodontic demand; an older population means restorative and implant work.
Growth. Population and housing growth over the last several years and the next few. A market that is thin today can be the right call if new rooftops are coming.

Step by step

Define what you are building. Specialty, patient type (fee-for-service, PPO, Medicaid), and the size of practice you want. The same neighborhood can be right for one model and wrong for another.
Screen regions, not addresses. Start at the state, metro or county level and shortlist areas where residents per office and income both work.
Count the competition properly. Use a list of practices that has been verified, not just an online map. Closed offices, duplicates and dental labs inflate automated counts and can make a good market look crowded.
Test specific sites. For each candidate address or lease space, look at drive-time population, nearby practices by specialty, income, age and growth.
Check what the numbers miss. Visibility, parking, access, co-tenants, signage and the lease terms themselves. Have a dental attorney review the lease before you sign.
Decide with a comparison, not a single report. Put two or three finalists side by side on the same measures.

Where the data comes from

Data	Common sources
Population, income, age, households	US Census Bureau, American Community Survey
Growth and housing	Census estimates, local planning departments
Dentist supply	State dental licensing boards, ADA Health Policy Institute, HRSA
Nearby practices	Google Maps (unverified), dental-specific verified databases
Consumer foot traffic and retail context	General site-selection platforms such as Esri Business Analyst, Placer.ai or Buxton

Public sources are free and reliable for who lives in an area. They are weak on how many dental offices already serve them, which is why the competition count is where most location mistakes start.

How Dentagraphics helps

Dentagraphics combines demographic data with 118,330 US dental practices verified by our research team, 97% of them rechecked within the last 12 months (how we verify). Dentists use it to:

run unlimited address, area, county and state searches with a Start/Buy membership ($149/month; a free plan covers national, state and county overviews),
compare many areas with an Area Analysis ($745), or examine one site with a Single-Site Study ($695), each reviewed with a demographer,
have a dental attorney review the lease before signing.

See what a finished report looks like: the sample Single-Site Study and the sample Area Analysis.

We do not broker practices or hold a stake in any location, so our only goal is that you open in the best market available.

Frequently asked questions

How many people does a dental practice need to be viable? A common guideline is a minimum of 2,000 to 3,000 residents per general dental office. Treat it as a starting point: compare the ratio in your area with the county and state averages, and adjust for specialty, practice model, income and growth.

Is drive time better than radius for a dental service area? Usually yes, especially outside dense cities, because it reflects how patients actually travel.

Can I use Google Maps to count competitors? It is a starting point, but it includes closed offices, duplicates and non-clinical listings. Verify the list before making a decision on it.
