Starting a dental practice in San Antonio, TX: demographics, competition and where to look

If you're deciding where to open a dental practice in San Antonio, the numbers point away from the most popular ZIPs. San Antonio ZIPs 78258, 78259, 78260 (Timberwood Park) and 78253 draw the most research from dentists on Dentagraphics and already have about 2,300 to 2,700 residents per general practice within 5 miles, fewer than the metro's typical 4,146. ZIP 78261 is the one popular area that is still relatively open, with 5,268 residents per general practice and a median household income of $122,845. ZIPs 78252 and 78245 pair more than 11,000 residents per general practice with incomes above $72,000, and few dentists are researching them.

This page puts the verified numbers for the San Antonio-New Braunfels metro area and each of its eight counties in one place, then walks through how to narrow from a county to a specific site. The San Antonio-New Braunfels area, as Dentagraphics defines it, covers Atascosa, Bandera, Bexar, Comal, Guadalupe, Kendall, Medina and Wilson counties.

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.

Across the whole metro there are 3,877 residents per general dental practice, close to the US average of 3,853 (slightly above it). Specialty practices are thinner: 10,172 residents per specialty practice, against a US average of 6,482. A metro average hides a lot, so the county numbers below matter more.

Source: Dentagraphics county pages, verified practice counts; Census ACS. US average: 3,853 residents per general practice. County figures, including residents and growth, come from each county's own page and may cover a different period than the metro figures (they do not add up exactly to the metro total), so compare counties with each other rather than with the metro.

What the numbers show

Residents per general practice is the simplest saturation measure: the lower the number, the more offices are competing for each resident.

  • More practices per resident than the US average: Kendall (3,094), Comal (3,669). By this measure these counties are the more saturated part of the metro.
  • Fewer practices per resident than the US average: Medina (7,025), Wilson (7,006), Atascosa (5,921), Guadalupe (5,064), Bandera (4,633), Bexar (3,995). By this measure these counties are less saturated.
  • Small counts move fast: Atascosa (9), Bandera (5), Kendall (17), Medina (8), Wilson (8) have fewer than 20 general practices, so a single new office changes the ratio noticeably. Check the current list before relying on it.
  • Growth: Comal County shows the highest growth figure in the metro (27.2%). Growth can make a thin market today a reasonable one later, or fill a quiet one with new offices.

A county is still a big place. Two addresses in the same county can look completely different once you draw a drive-time area around each one, which is the next step.

Where dentists are looking, and where there's still room

County averages hide the real story. To get closer, we looked at the San Antonio area town by town, and ZIP code by ZIP code inside the city of San Antonio. For each area we drew a 5-mile circle around it and counted the residents and the general practices our research team has verified inside it. Then we compared that with how much research dentists have done on that area on Dentagraphics over the past 12 months.

Across the metro, the typical 5-mile area has 4,146 residents per general practice. Higher means more residents for each office.

Popular and already crowded

These areas draw the most research from dentists, and they already have more offices per resident than the metro typically does.

AreaCountyResidents per general practice (5 mi)Median household incomeDentist research activity

San Antonio, ZIP 78259Bexar2,443$92,801High

San Antonio, ZIP 78253Bexar2,744$102,604High
San Antonio, ZIP 78247Bexar3,076$83,161High

Incomes in these ZIPs are well above the metro median, which is exactly why so many offices have opened there. A new practice here has to win patients away from established ones.

Popular and still open

One area draws as much research as the crowded group but still has room: San Antonio, ZIP 78261 (Bexar County), with 5,268 residents per general practice and a median household income of $122,845. Expect it to fill in. When many dentists are researching the same open market, the window can close quickly.

Room to grow, little attention

These areas have far more residents per office than the metro typically does, and comparatively few dentists are researching them.

San Antonio, ZIP 78237Bexar5,978$34,543Low

Seven of these nine areas have median household incomes under $55,000. They are lower-income, underserved areas, and they tend to suit Medicaid or community-focused practice models better than fee-for-service. ZIPs 78252 and 78245 are the exceptions, with incomes above $72,000 and more than 11,000 residents per general practice.

A high number of residents per office is a reason to look closer, not proof of an opportunity. A few offices just outside the 5-mile line can change the picture, and income, age and your practice model decide whether a market fits.

What this shows

  • Research and crowding overlap. The five areas dentists research most, San Antonio ZIPs 78258, 78259, 78260 (Timberwood Park), 78253 and 78247, all have fewer residents per general practice than the metro's typical 4,146, as low as 2,316.
  • One busy area is still open. ZIP 78261 draws high research activity and still has 5,268 residents per general practice, with a median household income of $122,845.
  • Most of the quiet room is lower-income. The low-attention areas with the most residents per office mostly have incomes under $55,000, which points to Medicaid or community-focused models. ZIPs 78252 and 78245 are the higher-income exceptions.

How we measured this: residents and household income come from Census ACS data by ZIP code. General practice counts come from Dentagraphics' verified practice database. Each 5-mile area combines the ZIP codes whose centers fall within 5 miles of the town or ZIP code. Research activity reflects how many different dentists researched addresses in each area on Dentagraphics in the past 12 months, with each dentist counted once, grouped into High, Medium and Low. We don't publish raw counts. These figures use a different method from the county table above, so compare areas with each other rather than with the county numbers.

How to narrow from a county to a site

  1. Define your practice model. General or specialty, fee-for-service, PPO or Medicaid, and the size of office you want. The same county can suit one model and not another.
  2. Compare counties. Use the tables above to shortlist counties where residents per practice, income and growth fit your model.
  3. Check drive-time areas around candidate sites. For each lease space or address, look at the population, income, age and nearby practices within a 5, 10 and 15 minute drive, not just a radius.
  4. Verify the competition by hand. Online maps include closed offices, duplicates and listings that are not clinical practices. Look at each nearby practice yourself, or use a list that a person has already checked.
  5. Weigh rent against visibility. A cheaper space off the main road can cost you in new patients. Visibility, signage, parking and access are worth paying for up to a point.
  6. Have a dental attorney review the lease. Term, renewal options, exclusivity, build-out allowance and personal guarantees are where startup costs hide.

Why not rely only on the landlord's or broker's demographics

Landlords and commercial real estate brokers often hand over a demographic summary with a listing. It is a fine starting point, but remember who prepared it: a landlord earns rent once you sign, and a broker is usually paid when the deal closes. Their numbers describe the property they want to lease or sell.

Government business counts have a similar limit. They are useful for a broad picture, but they count establishments by industry code, do not separate general from specialty practices, and do not give you the list of offices you would actually compete with.

Dentagraphics does not broker practices and holds no stake in any location. Our competition counts come from 118,330 US dental practices verified by hand by our research team. Whatever source you use, ask where its competitor count came from and whether a person checked it.

Who you'll need to open a practice in San Antonio

A startup practice takes a small team. These are the roles to line up, and what to ask each one.

  • A dental-focused commercial real estate broker, ideally one who represents you as the tenant. A tenant's broker negotiates the lease for you rather than for the landlord. Ask how many dental leases they have done, who pays their commission, and whether they also represent landlords in the area.
  • A lender with dental practice financing. A lender that works with dental startups understands build-out, equipment and the months before collections catch up. Ask what they need from you to approve a startup loan, how long any interest-only period lasts, and whether the loan covers build-out, equipment and working capital.
  • A dental CPA. An accountant who works mainly with dentists can build your startup budget and set up your books, payroll and taxes. Ask how many startups they have worked with and what overhead they expect in your first year.
  • A dental office architect or designer, and a contractor. Dental offices need plumbing, electrical, vacuum and air lines that a general office does not. Ask for recent dental projects you can visit, and whether they will look at a space and estimate the build-out before you sign the lease.
  • A dental attorney for the lease and your business entity. Ask them to review the lease term, renewal options, exclusivity, build-out allowance and personal guarantee, and to recommend the entity type that fits your state and plans.
  • Independent market analysis before you choose a location. The broker and lender are paid when a deal happens. Dentagraphics holds no stake in any location, so a demographer can compare your candidate sites and tell you plainly whether the market fits your practice. Ask any source of market data where its competitor count came from and whether a person checked it.
