How to open a dental practice: the step-by-step guide

Most dentists who open a practice get the tasks right and the order wrong. They tour a suite, fall for it, sign a letter of intent, and then ask what the project costs. By then the space has set the budget, instead of the budget setting the space. This guide walks through every stage in the order that keeps you in control, with what each one produces and what not to sign yet.

Should you start a practice or buy one?

A startup (also called a de novo practice) gives you total control: location, size, design, systems, brand and team. You also start with zero patients, so the first months run on borrowed working capital while you build a schedule. An acquisition buys existing collections from the first Monday, but you inherit someone else's charts, staff, fee schedule, equipment and lease. The lender's view differs too. A startup loan is underwritten on projections. An acquisition loan is underwritten on the seller's real cash flow.

Ownership is still the norm, but it's arriving later. The ADA Health Policy Institute reports that 72.5% of U.S. dentists were private-practice owners in 2023, down from 84.7% in 2005, and that younger dentists still become owners, just later in their careers [12]. If good practices are for sale in your target area and the numbers survive diligence, buying can beat building. If the market has room and you want a practice the existing inventory can't give you, a startup wins. A third path, buying a practice and then relocating it into a right-sized space, combines both. I compare them side by side in startup vs. acquisition.

Are you financially ready to own a practice?

Before a lender looks at your project, it looks at you. Dental lenders typically look at four things, and each one is easier to fix a year out than a month out.

• Credit. Payment history (35%) and amounts owed (30%) make up about 65% of a FICO Score [5]. Late payments and maxed-out cards cost more than almost anything else you can control.
• Liquidity. Cash and investments you can show. It covers the gap between what the loan funds and what the project needs, and it shows a lender you can absorb a surprise.
• Production history. Your associate production, documented. On a startup this is the strongest evidence that your projections are realistic.
• Debt, including student loans. Lenders look at total obligations and your personal living costs, not just the new practice loan. Student loan payments count.

Published minimums vary by lender, and most don't publish them at all. Ask each lender for its thresholds in writing. Lenders also weigh what the practice can carry. Many dental lenders look for a debt-service coverage ratio (DSCR) of at least 1.25, as a guideline rather than a strict minimum [3][4]. That means cash flow available for debt of at least $1.25 for every $1.00 of loan payments. An ADA News expert column notes that opening a practice often takes $500,000 at minimum [1], so readiness is a real question, not a formality. The full list is in what dental lenders actually want to see.

How much does it cost to open a dental practice?

The Alithos estimator assumes a 4-operatory startup in leased space at standard finish costs about $746K–$824K all-in, including $85,000 of working capital. It counts construction at $170 per square foot, equipment at $42,000 per operatory, a $60,000 imaging package (sensors and a pano), cabinetry at 10% and soft costs at 12% of construction, and IT and furniture at $45,000 plus $3,000 per operatory. These are planning assumptions, not survey data and not a quote. For outside context, a 2026 dental lawyer's guide puts a typical build-out budget at $300,000 to $600,000 or more, before working capital and soft costs [2].

Payments assume the point estimate is fully financed over 15 years at 8.25%, the estimator's loan assumption, not a rate offer. The full table, including premium finish and ground-up builds, is on the Alithos cost benchmark [20]. Every line item is broken down in the dental practice startup costs guide, and you can run your own scenario in the estimator.

Three choices move the number more than anything else. Finish level and imaging come first: the same 5-operatory leased suite at premium finish with a CBCT plans at $1,174K–$1,298K in the model, against $887K–$980K at standard. Building from the ground up comes next: a 5-operatory ground-up build at standard finish plans at $1,379K–$1,525K, and that is before land. Size is the third. Every operatory you add brings its own square footage, equipment and cabinetry with it. That's why the space requirement comes from your production plan and not from the suite a broker happens to show you.

What are the steps to open a dental practice?

There are 13 stages, grouped into four phases. Each one produces something specific, involves specific people, and has a commitment you should not make yet. The rule behind the order is simple: in stages 1–3 nothing is signed and nobody selling you anything is in the room. Want a one-page version to print? Use the dental practice startup checklist.

Phase 1: Decide

1. Define your vision

   Decide what kind of dentistry you want to do, for which patients, and at what size. That covers procedures, payer mix, number of doctors and hygienists, and the hours you want to work. Every downstream number traces back to this.

   Output: a written practice profile. Who: you, plus anyone whose life the practice changes. Don't sign yet: anything. No showroom visits.

2. Check your personal financial readiness

   Pull your credit reports, list every debt, document your production history and add up your liquid assets. Fix problems now. I recommend starting this 6–12 months before anything else.

   Output: a personal balance sheet and a clean credit file. Who: you and, ideally, a dental CPA. Don't sign yet: new car loans or other new debt.

3. Build a verified budget plan

   Turn the vision into numbers: how much space you need, a line-item equipment and imaging budget, construction and soft costs, working capital, and whether the projected cash flow covers the debt. Compare leasing, building and buying a condo before you tour anything.

   Output: one defensible project number and the debt it supports. Who: you and an independent budget planner. Don't sign yet: an LOI, a lease or a dealer design agreement.

4. Assemble your advisory team

   Hire a dental CPA and a dental attorney, and open conversations with two or more dental lenders. Do this after the budget, so you interview them with numbers in hand.

   Output: a CPA, an attorney and a lender shortlist. Who: you. Don't sign yet: exclusive agreements with anyone paid by the size of the project.

Phase 2: Secure

5. Study demographics and set a site strategy

   Decide where the patients are, who already serves them and what the area supports, before touring a single suite. Define a target area and must-haves: visibility, parking, access and zoning.

   Output: a target trade area and a site checklist. Who: you, public data, and a tenant-rep broker if you use one. Don't sign yet: a broker agreement you haven't read.

6. Get financing pre-approval

   Take a lender-ready package (budget, projections, personal financials, production history) to at least two dental lenders and ask for term sheets. Compare rate, term, fees, prepayment terms and working-capital structure.

   Output: two or more term sheets. Who: you, your CPA and the lenders. Don't sign yet: a loan commitment before you've compared terms.

7. Select a site and negotiate the LOI

   Tour sites that fit the space requirement and the budget. Negotiate the letter of intent against your verified number, not against your excitement. Keep a second option alive.

   Output: a negotiated LOI on a site that fits the plan. Who: you, your broker and your attorney. Don't sign yet: an LOI on a suite you haven't priced against the budget.

8. Negotiate the lease or purchase

   Work through the tenant improvement allowance, rent escalations, exclusivity, assignment, renewal options and restoration clauses. If you're buying, cover title, inspections and zoning. Your attorney reviews before you sign, always.

   Output: a signed lease or purchase agreement that matches the budget. Who: you, your attorney and your broker. Don't sign yet: personal liability terms your attorney hasn't reviewed.

Phase 3: Build

9. Complete design and engineering

   An architect turns the space requirement into a floor plan, then engineering drawings for plumbing, electrical, HVAC, vacuum and compressed air. Measure every draft against the budget.

   Output: permit-ready drawings. Who: architect, engineers, your equipment choices. Don't sign yet: a dealer design that assumes a full equipment order.

10. Get competitive equipment quotes

    Write one equipment and imaging list from the budget, then get two or three dealer quotes against that same list. List price is a starting point, not the price.

    Output: a priced equipment package that fits the budget. Who: you, dealers and an independent reviewer. Don't sign yet: a single dealer's quote with nothing to compare it to.

11. Build out the space

    Get contractor pricing on the drawings, have your attorney review the construction contract, and price every change order against the plan before you approve it.

    Output: a finished, inspected suite. Who: general contractor, architect, your attorney, the city. Don't sign yet: change orders you haven't priced.

Phase 4: Open

12. Set up systems and hire your team

    Choose practice management software, set a fee schedule, start insurance credentialing, hire and train staff, and launch marketing. I recommend starting 4–6 months before opening, not four weeks.

    Output: a credentialed, staffed, scheduled practice. Who: you, an office manager, vendors and payers. Don't sign yet: long software or marketing contracts you haven't compared.

13. Open and stabilize

    Open the doors, then manage working capital against the ramp plan and track production and collections against the budget's targets from day one.

    Output: a monthly report of actuals against plan. Who: you, your CPA and your team. Don't sign yet: an expansion before the first one stabilizes.

How long does it take to open a dental practice?

There is no reliable national average, and I won't invent one. The timeline depends on your market, your space, your permits and how fast you decide. What I can give you is the lead time I recommend for each phase, counted back from the day you want to open.

The most expensive sentence in dental real estate is "our lease is up in 60 days." Leverage belongs to whoever isn't out of time. Start earlier than feels necessary.

Who do you need on your team, and how is each paid?

A startup brings a lot of helpful people to the table. Ask each one the same question: how are you paid? It doesn't make anyone dishonest. It tells you whose interests their advice is built around.

Notice that the people paid by the size of the project are also the ones offering free help. That's the gap an independent budget fills: everyone else gets the same verified numbers to work from. If you're weighing a full-service startup program, a dealer program and independent help, see dental office planning options compared.

How do you choose a location for a dental practice?

Choose the area first and the building second. A beautiful suite in the wrong trade area is a long, expensive lesson. Work through five questions, in this order:

• Demographics. Population, growth, household income, age mix and insurance coverage in the area you'd draw from.
• Competition. How many dental offices already serve that area, and what kind: general, specialty or group-affiliated.
• Visibility. Can patients see you and find you? Signage rights matter here, and both the landlord and the city usually approve signs.
• Parking and access. Enough spaces for a full schedule, easy entry, and accessible routes.
• Zoning. Confirm with the city that a dental office is an allowed use at that address before you negotiate.

Two free public sources give you a first read on supply. The ADA Health Policy Institute publishes dentist workforce data. Nationally there were 205,088 professionally active dentists in 2025, about 60 per 100,000 people [11], and you can compare your target area against that. The U.S. Census Bureau's County Business Patterns counts establishments by industry and county [13]. Offices of dentists are NAICS code 621210. Neither source replaces driving the area at 8 a.m. and 5 p.m., but both keep the decision honest.

What licenses and registrations do you need before opening?

Paperwork has lead times, and some of it (credentialing in particular) controls when you can bill. Start early. The core list for most U.S. startups:

• State dental license in the state where you'll practice, plus any practice or entity registration your state dental board requires.
• Business entity formed with your state, set up with your attorney and CPA.
• Employer Identification Number (EIN) from the IRS. You never pay a fee for an EIN, and you can apply online directly with the IRS [14].
• National Provider Identifier (NPI) through CMS's NPPES. Covered health care providers must use NPIs in HIPAA standard transactions [15]. Dentists commonly hold an individual (Type 1) NPI and the practice an organization (Type 2) NPI.
• DEA registration for the new location. Federal rules require a separate registration for each principal place of business or professional practice where controlled substances are handled [16][17]. Check whether your state also requires its own controlled-substance registration.
• X-ray equipment registration with your state's radiation control program, which may also require shielding plans or inspections.
• Local business license from your city or county.
• Building permit and certificate of occupancy for the build-out. In most places you can't see patients in the space until it passes final inspection and the city signs off on occupancy.
• Payer credentialing, often started through CAQH ProView [18], with each insurance plan you'll accept.

How do you finance a new dental practice?

Most startups are financed with a dental-focused practice loan or an SBA 7(a) loan, or both. Dental lenders generally view dentists as lower-risk borrowers, and some advertise high leverage. Bank of America Practice Solutions, for example, advertises up to 100% project financing for new office startups, subject to credit approval [10]. The SBA 7(a) program goes up to $5 million, with terms generally up to 10 years for equipment and working capital and up to 25 years for real estate [6][7]. Under SBA SOP 50 10 8, startups need an equity injection of at least 10% of total project cost on SBA loans [8].

What goes in a lender-ready package? Expect to provide a project budget with line items, a monthly cash-flow projection through the ramp, your personal financial statement and tax returns, your production history as an associate, a CV, and the proposed site and lease terms if you have them. A lender can only price the risk it can see. A package built on a verified budget answers the questions before they're asked, and that makes the term sheets easier to compare.

Rates move. The bank prime rate was 7.00% in the Federal Reserve's October 30, 2026 H.15 release [9]. The SBA caps the variable rate on a 7(a) loan over $350,000 at prime plus 3.0% [6], which puts that ceiling at about 10.0%. That's a ceiling, not a typical rate. Get at least two term sheets and compare them line by line. The details are in the dental practice financing guide, and you can test your own numbers with the DSCR calculator.

How do you find and lease space for a dental office?

Size the space from your production plan, then find a suite that fits it. Don't let the suite set your size. The Alithos estimator assumes 500 square feet per operatory for 3–5 operatories, 450 for 6–7, and 425 for 8 or more. Work out your own figure with the operatory square footage calculator, and read how much space you actually need.

Expect competition for good medical space. JLL reports medical office occupancy hit a record 92.7% in Q4 2025, with national average rents in the mid-$20s per square foot per year and new developments leasing at over $40 [19]. That's a national average. Your market will differ. The lease terms that matter most are the tenant improvement allowance, escalations, exclusivity, assignment and restoration. Lease or own, the full picture is in the dental office real estate guide.

How do you plan equipment and the build-out?

Price the equipment list before the floor plan locks, so the equipment fits the budget and the plan fits the equipment. Equipment for a standard build is often $100,000 to $200,000 [2]. The Alithos estimator assumes $42,000 per operatory at standard spec and $58,000 at premium, plus $60,000 for sensors and a pano or $130,000 with a CBCT. Vendor-published prices for a new CBCT alone run roughly $40,000 to $150,000 [21]. The dental equipment cost guide breaks down each line.

For construction, a 2026 dental lawyer's guide gives $150 to $350 per square foot for a leasehold build-out, and often $400 or more for ground-up [2]. The Alithos model's $170–$220 lease rates sit inside that range. Its $340–$420 ground-up rates are on the conservative side, and your market may run higher. Read every contractor quote for what it excludes. See the dental office build-out cost guide for the full breakdown.

What happens in the first months after opening?

A startup opens with a full overhead bill and a partial schedule. The gap between them is working capital, and running out of it is one of the most avoidable problems a startup can have. The Alithos estimator's default is $85,000. Your real number depends on your marketing runway, your payer mix, how quickly new patients arrive and your personal living costs. Insurance collections also lag production by weeks, so cash arrives later than the work.

Track three numbers every month against the plan: production, collections and overhead. For a sense of where a mature practice lands, one dental lender writing in ADA News puts overhead in a well-run general practice at 58% to 68% of collections [3]. The ADA Health Policy Institute reports average 2025 gross billings of $965,660 per private-practice general dentist [12]. Those are steady-state figures, not what a new practice sees in month three. The ramp math is in how much working capital a startup needs.

Hold a short monthly review with your CPA or office manager. Compare actual new patients, production, collections and overhead with the ramp plan, and decide early what to change: marketing spend, hygiene hours, staffing or fees. Small gaps caught in month two are cheap to fix. The same gaps found in month nine use up the working capital that was meant to carry you.

What are the most common dental startup mistakes?

• Doing the steps in the wrong order. Signing before the budget means the budget serves the lease, not the other way around.
• Letting the suite set the size. A space that's too big adds rent, build-out and equipment you didn't need. Size from production first.
• Signing an LOI before the budget exists. The LOI frames the lease. Negotiate it against a verified number.
• Buying equipment at list price. One quote with nothing to compare it to isn't a price. Get two or three quotes against one list.
• Accepting a "free" design that assumes a full order. Design paid for by the equipment margin tends to fit the equipment order.
• Thin working capital. The build-out gets every dollar and the ramp gets what's left.
• Only one term sheet. Without a second lender's offer you can't tell whether the first one is good.
• Unpriced change orders. Small approvals during construction add up. Price each one against the plan first.

More of these are in the hidden costs of opening a dental office.
