How to start a dental practice: every step, in order

Starting a dental practice takes ten steps: decide whether to build or buy, define your practice model, line up your advisors and financing, choose the market and then the site, write the business plan, sign the lease, design and build out the office, handle licensing, compliance and insurance credentialing, hire and train your team, and market the opening. A from-scratch startup usually takes about 9 to 18 months from first planning to first patient. The step most startups get wrong is location, because it is chosen early, it is hard to undo, and it decides how fast the schedule fills.

This guide covers every step in the order it happens, with the numbers that matter at each one and where to find them. If you are still deciding whether to start or buy, read start a dental practice from scratch or buy one first. If you are buying, see how to buy a dental practice, step by step.

The steps at a glance

#	Step	Typical time	What decides it
1	Decide: start or buy	2 to 8 weeks	Your finances, timeline and the markets you would live in
2	Define your practice model	2 to 4 weeks	Specialty, payer mix, size, target patients
3	Line up advisors and financing	1 to 3 months	Lender pre-approval, dental CPA, dental attorney
4	Choose the market, then the site	1 to 4 months	Residents per verified practice, income, age, growth, access
5	Write the business plan	2 to 6 weeks	Realistic patient ramp for that specific site
6	Negotiate and sign the lease	1 to 3 months	Term, exclusivity, build-out allowance, assignment
7	Design, permits and build-out	3 to 6 months	Local permitting, plumbing, electrical, suction and air
8	Licensing, compliance and credentialing	3 to 4 months, in parallel	State rules, each insurer's timeline
9	Hire and train your team	1 to 2 months, in parallel	Local labor market for assistants and hygienists
10	Market the opening	2 to 3 months, in parallel	Who lives near the site and what they need

These are planning ranges, not guarantees. Steps 8 to 10 overlap the build-out, which is why the total is shorter than the sum. See how long it takes to open a dental practice for the full timeline.

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 context: what the national numbers say

There are about 205,000 professionally active dentists in the US, 60.0 per 100,000 people (ADA Health Policy Institute, 2025).
Practice ownership is falling, but mostly early in careers. About 73% of dentists owned their practice in 2021, down from 84.7% in 2005, and the ADA Health Policy Institute's 2025 analysis found younger dentists still become owners, just later in their careers.
Demand for dentists is still growing. The Bureau of Labor Statistics projects dentist employment to grow 6% from 2025 to 2035, with about 4,800 openings a year. The median dentist earned $176,110 in May 2025.
The US has about 3,860 residents per active general dental practice, based on Dentagraphics' 88,367 hand-verified general practices. That ranges from 2,870 in California to 5,753 in Delaware by state, and far more widely between neighborhoods.

The last point is the one that matters most for a startup. The difference between a crowded site and an open one a few miles away is often larger than the difference between states.

Step 1: Decide whether to start or buy

Before anything else, decide which path you are on, because it changes every later step.

Buying gets you patients, staff and cash flow from the first month, but you inherit the location, equipment and culture, and you pay for goodwill.
Starting from scratch lets you choose the site, design and team, but you carry rent, payroll and loan payments while the schedule fills.

The market usually decides. In a crowded area, buying an existing patient base is often safer than competing for new patients. In a growing area with room for another office, a well-placed startup can do very well. Many dentists keep both options open for a few months and compare a startup budget against real practices for sale in the same area.

Step 2: Define your practice model

Write down, on one page:

Type: general, pediatric, orthodontic or another specialty. Specialists need a different market test, often based on referring general dentists. See how location analysis differs for specialists.
Payer mix: fee-for-service, PPO, Medicaid or a mix. A fee-for-service model and a Medicaid model need very different neighborhoods.
Size: operatories at opening and at full build-out. Many solo startups plan four to six operatories and equip only some at first.
Patients: families, older adults, a language community, a commuter corridor.

Every later step tests against this page. It is also the first thing a lender and a landlord will ask about.

Step 3: Line up advisors and financing

Bring in a small team early, before you look at spaces:

A lender that finances dental startups. Get pre-qualified so you know your budget. Many dental startups use conventional practice loans; the SBA 7(a) program is another option, with a maximum loan of $5 million and terms up to 25 years when real estate is involved.
A dental CPA for the entity, the budget and the cash-flow projection.
A dental attorney for the lease, the entity and employment agreements.
A tenant-side real estate broker who represents you, not the landlord.
A dental office designer and contractor once you have a site.

For who to hire and when, see who can help you start a dental practice.

What it costs. Published estimates for a solo general startup vary widely, commonly from the mid six figures to more than $1 million, depending on size, construction, equipment and how much working capital is included. Treat any national figure as a rough guide and get local bids. Working capital matters as much as the build-out: the budget has to carry you until collections cover overhead.

Step 4: Choose the market, then the site (the step most startups get wrong)

Location is where startups lose the most money and time, for three reasons. It is chosen early, before the business plan is real. It is locked in by a lease that often runs 10 years. And the most obvious choices are usually the most crowded.

Dentagraphics' 2026 national study of 118,330 hand-verified practices found:

The richest areas are the most crowded. In suburban and urban ZIP codes, the top tenth by household income has a median of 2,380 residents per general practice within 5 miles. The bottom tenth has 4,828.
Family areas have more room. ZIPs with the most children have 37% more residents per practice than ZIPs with the fewest.
Growth barely changes the picture. The fastest-growing tenth of ZIPs has only about 7% more room than the fastest-shrinking tenth. Dentists follow growth quickly.
Nearby sites can be very different. Among pairs of ZIPs whose centers are within 5 miles of each other, about one in seven differ by 50% or more in residents per practice.

Work from wide to narrow:

State and metro. Shortlist where you can be licensed and want to live, then compare. Metro averages range from 2,442 residents per general practice in the San Francisco Bay Area and 2,479 in Los Angeles to 4,065 in Atlanta and 4,458 in St. Louis. See residents per general practice by state and the 25 largest metros ranked.
County and town. Look for areas with more residents per practice than their neighbors, and income, age and payer mix that fit your model.
Site. Compare the area within about 5 miles, or a 10 to 15 minute drive in suburbs, around each candidate space.

At the site level, check:

Check	What good looks like	Where to get it
Residents per general practice within 5 miles	Above nearby areas; the median suburban or urban ZIP is 3,391, the top quarter is above 4,628	A verified practice count, not an online map
Household income and age	Fits your fee and payer model	Census Bureau American Community Survey
Children under 18	High share if you see families or children	American Community Survey
Growth	Steady, with new rooftops nearby	Census estimates, local planning department
Competition trend	Few new practices opened recently	Year-over-year practice counts
Access and visibility	Parking, signage, traffic, anchors	Site visit at different times of day
Space	Can take dental plumbing, electrical, suction and air	Your designer and contractor

Why a verified count matters. Online maps and directories include closed offices, duplicates and dentists who moved, so a raw count can make an open area look crowded, or the reverse. See how to tell if an area has too many dentists and location mistakes that cost startups the most.

Step 5: Write the business plan

Write the plan after you have a target site, not before, because the patient ramp depends on the site. Include:

Startup budget: build-out, equipment, technology, furniture, supplies, deposits, professional fees and working capital.
Monthly cash-flow projection for at least three years, with a conservative, expected and optimistic case for new patients per month.
The market case: residents per practice, income, age and growth around the site, and who your patients will be.
Your fee schedule and payer plan, including which insurance networks you will join.

Lenders often ask for the market analysis as part of the plan, so do Step 4 properly and the plan writes itself faster.

Step 6: Negotiate and sign the lease

A dental lease is long and expensive to exit. Before you sign, have a dental attorney review:

Term and renewal options, so you can stay long enough to pay off the build-out.
Exclusivity, so the landlord cannot lease to another dentist in the same center.
Tenant improvement allowance and rent-free period for the build-out.
Assignment, so you can sell the practice with the lease later.
Personal guarantee and its limits.
Use and infrastructure: confirm the space can support dental plumbing, electrical, suction and compressed air.

Dentagraphics members can have a dental real estate attorney review the lease before they commit.

Step 7: Design, permits and build-out

Work with a designer and contractor who have built dental offices. Plumbing to each operatory, electrical capacity, suction, compressed air, sterilization flow and x-ray requirements drive both cost and schedule. Permit timing depends on your city or county. Order equipment early enough to arrive when construction ends; some items have long lead times.

Step 8: Licensing, compliance and insurance credentialing

Run these in parallel with the build-out:

State dental license in the state where you will practice, and any facility permit or registration your state requires.
Business entity, EIN and state tax registration. The IRS issues an Employer Identification Number free online.
NPI numbers. Each dentist needs an individual (Type 1) National Provider Identifier, and the practice usually needs an organizational (Type 2) NPI. Both are free from NPPES.
DEA registration if you will prescribe controlled substances ($888 for three years), plus any state controlled substance registration.
X-ray equipment registration with your state's radiation control program.
OSHA and infection control: the OSHA Bloodborne Pathogens Standard and the CDC's infection prevention guidance for dental settings.
HIPAA privacy and security policies.
Malpractice, property, liability and workers' compensation insurance.
Insurance credentialing. Timelines vary by payer and state, and Medicaid enrollment can take months (ADA News, 2026). Many startups plan on roughly three to four months per network and start as soon as they have an address and NPI.

Step 9: Hire and train your team

A typical solo startup opens with a front-desk lead, one or two dental assistants and a hygienist, sometimes part time. Hire four to eight weeks before opening so you can train on your software, your sterilization flow and your scheduling rules. The local labor market for assistants and hygienists is part of the site decision: check wages and availability before you sign the lease.

Step 10: Market the opening

Start two to three months before opening day:

Google Business Profile, website and online listings as soon as you have an address.
Signage on the building as early as the landlord allows.
Direct mail and local outreach to households near the site. The demographics you studied in Step 4 tell you who to reach and what to say.
Insurance network directories, once credentialing is complete.

Frequently asked questions

What is the first step to starting a dental practice? Decide whether you are starting or buying and write down your practice model: specialty, payer mix, size and target patients. Then line up a lender and a dental CPA so you know your budget before you look at spaces.

How long does it take to start a dental practice? About 9 to 18 months from first planning to first patient for a from-scratch startup. Site selection and build-out take the longest; credentialing, hiring and marketing run alongside them.

How much does it cost to start a dental practice? Estimates vary widely, commonly from the mid six figures to more than $1 million for a solo general practice, depending on size, construction, equipment and working capital. Get local bids from a dental contractor and equipment supplier.

What is the biggest mistake when starting a dental practice? Choosing a site before checking the market. The richest neighborhoods are usually the most crowded with dentists, and two sites a few miles apart can face very different competition.

How many people does a dental practice need to be viable? There is no single number, but compare residents per verified general practice around the site with nearby areas and the US average of about 3,860. In suburban and urban ZIPs the median is 3,391 within 5 miles; above 4,628 is the top quarter for room.

Can I start a dental practice right out of dental school? Some dentists do, but most work as associates first. ADA Health Policy Institute data shows ownership among younger dentists has fallen, and that many become owners later in their careers.

Do I need a business plan to open a dental office? Yes. Lenders require one, and it forces you to test the patient ramp against the actual site. Include a conservative case.
