Starting a Dental Practice from Scratch: The Complete Financial Guide

A de novo dental practice costs $450K–$800K to launch, will lose money for 12–24 months, and — if the location works — can generate more income over a 20-year career than buying an established practice ever would. This guide covers what you actually need to know before you sign anything: startup costs, SBA financing, entity setup, year-1 tax strategy, and the production milestones that tell you whether you're on track.

When de novo makes financial sense

The case for de novo usually comes down to three factors: you can't find a practice worth buying at a reasonable price, you want to build something specific (a specialty, a particular patient experience, a location no existing practice controls), or the math on buying simply doesn't pencil in your target market.

Where de novo has a structural advantage: you can design the practice around your production style, pick the exact location demographics you want, and avoid paying a multiple for goodwill you'll have to rebuild anyway if the selling dentist leaves. The tradeoff is financial pain upfront — negative cash flow for the first 12–24 months while you build a patient base, with no existing revenue stream to service your debt.

Where it fails: location choices based on convenience rather than demographics, underestimating the working-capital gap, and launching without enough personal financial runway to survive the ramp period. The practices that struggle most aren't typically in the wrong market — they're undercapitalized.

Startup cost breakdown

Plan for $450K–$800K total to open a de novo general dentistry practice, depending on your market, build-out scope, and equipment choices. Here is where the money goes:

How de novo practices are financed

SBA 7(a): the standard vehicle

Most de novo dental builds are financed with an SBA 7(a) loan, which can fund up to $5M and doesn't require the same historical cash flow documentation that conventional commercial loans do — essential for a business with no revenue history.³

Key SBA 7(a) mechanics for de novo practices in 2026:

• Down payment: Typically 10% equity injection required. On a $600K project, that's $60K from you.
• All-in rate: Approximately 9–11% for a 10-year term in 2026 (prime + 2.75% for loans over $350K).
• Collateral: Equipment and buildout are collateral; lenders will also typically require a personal guarantee.
• DSCR: Unlike an established-practice acquisition where historical cash flow satisfies this, a de novo lender underwrites on projected revenue. Your dental-specific lender will have a production ramp model; understand their assumptions.
• Working capital component: Some SBA lenders structure a separate working-capital portion of the loan (drawn down monthly during the ramp) rather than requiring you to cover losses from personal cash.

Equipment financing: separate from build-out

Many practices finance dental equipment separately through equipment lenders (Stearns Bank, Live Oak, Provide), keeping the SBA loan focused on the build-out and working capital. Equipment loans are typically 5–7 year terms at fixed rates. The advantage: equipment serves as its own collateral, often with faster approval than SBA, and you can deploy 100% bonus depreciation (via OBBBA 2025, made permanent) in year 1 regardless of how the equipment is financed.⁴

Entity structure: set this up before you sign the lease

The most common and costly timing mistake de novo dentists make: signing the lease in their personal name or under a placeholder LLC, then trying to restructure after the fact. Set up your entity before you execute any binding agreements.

The typical structure for a dentist starting a practice:

• Operating entity: Professional Limited Liability Company (PLLC) or Professional Corporation (PC), depending on your state's dental practice act requirements. This entity owns the practice, employs staff, and receives collections.
• S-corp election: File Form 2553 to elect S-corp tax status for the PLLC or PC within 75 days of formation (or by March 15 of the current year for existing entities). This is the mechanism that lets you split income between W-2 salary (subject to payroll taxes) and distributions (not subject to self-employment tax). At $200K+ net, this saves $10,000–$25,000/year in payroll taxes. See the S-corp tax savings calculator.
• Real estate holding LLC (optional): If you're purchasing the condo or building, hold it in a separate LLC that leases to the operating entity. This isolates the real estate liability and creates a deductible rent expense inside the practice. See dental office buy vs. lease.

Year 1 tax strategy: maximize deductions during the ramp

Year 1 is paradoxically your best tax year for deductions and one of your worst for income. That mismatch creates a planning opportunity.

Section 179 and bonus depreciation

In 2026, you can deduct up to $2,560,000 of qualified business property under IRC §179 in the year it's placed in service, provided the asset is used more than 50% for business purposes.⁴ The OBBBA (July 2025) also restored 100% first-year bonus depreciation permanently for qualified property placed in service after January 19, 2025 — including dental equipment, operatory buildout components, and technology purchases.

On a $300,000 equipment investment, 100% bonus depreciation generates a $300,000 deduction in year 1. At a 37% marginal rate, that's $111,000 of tax savings — but only if you have enough income to absorb it. In a ramp year when you might have $80,000 of net income and $300,000 of equipment deductions, the excess becomes a net operating loss (NOL) that carries forward to future years at full value (no 80% limitation for dental practice NOLs under current law).

Coordinate with your CPA on whether to elect Section 179 or take bonus depreciation: Section 179 requires taxable income (you can't create an NOL with §179 alone); bonus depreciation can. In a genuine ramp year, bonus depreciation may be more valuable because it carries forward without restriction.

Retirement plan: open it before December 31

Even in a ramp year with limited income, establish your solo 401(k) before December 31. The plan must exist by year-end for contributions to count for that tax year (unlike a SEP-IRA, which can be opened until your tax filing deadline). In 2026, you can shelter up to $72,000 in a solo 401(k) — $24,500 employee deferral plus employer profit-sharing contributions up to 25% of your W-2 compensation (if S-corp) or 20% of net SE income (if sole prop).¹

In a year where you're managing cash flow carefully, don't over-contribute — but do establish the plan. A solo 401(k) with a Roth option also lets you make Roth contributions in lower-income ramp years, creating tax-free retirement income for the higher-income years ahead.

Note: Once you hire a full-time W-2 employee (typically a dental hygienist or full-time assistant), you lose solo 401(k) eligibility and must convert to a group 401(k) plan. See group 401(k) for dental practices with employees.

Staffing: when can you afford to hire?

Staff is usually your largest expense — 25–30% of collections in a stable practice — and the most consequential decision you'll make in year 1. The de novo-specific challenge: you're hiring before you know exactly how much you'll produce.

The minimum viable team to open: front desk plus dental assistant. Many de novo dentists launch with exactly two employees and add the hygienist in month 4–6 when they have enough recall patients to fill a partial hygiene schedule (3 days/week before full-time).

Production ramp benchmarks

Understanding what a typical de novo ramp looks like helps you distinguish "this is normal" from "this practice has a location problem." These are median outcomes — your results will vary by market, demographics, and marketing investment:

If you're at month 18 and still not covering overhead, investigate: is it a patient acquisition problem (marketing, location visibility), a payer mix problem (too many fee-for-service in a price-sensitive market), a scheduling problem (not enough operatories scheduled, hygiene not at capacity), or a collection rate problem (production is there but not being collected)?

Insurance before you open the doors

Do not see a single patient without these in place:

• Dental malpractice (occurrence form preferred): Claims-made policies are cheaper but require tail coverage when you eventually change carriers or retire. Occurrence form costs more annually but covers you for any incident that occurs while the policy is active, regardless of when the claim is filed. Typical limits: $1M/$3M. See dental malpractice insurance guide.
• Business owner's policy (BOP): Covers property damage to your buildout and equipment, general liability, and business interruption. Your landlord will require general liability as a lease condition.
• Own-occupation disability insurance: This is the most important personal insurance you'll buy. Own-occupation means the policy pays if you can't perform your specific dental specialty — even if you could technically work as something else. For a dentist, this isn't theoretical: hands, vision, and fine motor function are occupational hazards. Buy it young when rates are lowest; a 30-year-old dentist pays roughly 1.5–2.5% of benefit annually, which roughly doubles by 45. See disability insurance for dentists.
• Business overhead expense (BOE) insurance: Pays fixed practice overhead (rent, staff salaries, loan payments) during a disability that prevents you from working. Personal disability replaces your income; BOE replaces the practice's fixed costs so you don't have to choose between your mortgage and your staff's wages. See BOE insurance guide.
• Key person life insurance: If you have a business loan, the lender may require it. Even if they don't, consider it: if you die in year 2 of a de novo build with $600K in SBA debt, the policy proceeds give the practice time to wind down or transfer without immediate default.

Financial milestones to track

These are the indicators that tell you your de novo practice is financially healthy versus undercapitalized or stalled:

The financial planning gaps most de novo dentists miss

Three categories show up repeatedly in practices that get into financial trouble in years 2–3:

No personal salary plan. Many de novo dentists take minimal or no salary in year 1 to conserve cash — which is sometimes necessary — but fail to model when they'll start paying themselves and how. Without a planned transition from "zero distributions" to "market-rate W-2 plus distributions," owners end up in year 3 still underpaying themselves, funding the practice's growth at the cost of their personal financial plan. Model this before you open.

No retirement plan established. The ramp years are when tax deductions matter most (you're often in a high marginal bracket once the practice matures) and the early years are when compounding matters most for retirement. Missing the solo 401(k) setup in year 1 and 2 is a real cost — not just deferred tax savings but deferred compounding on assets that should have been invested decades before retirement.

No exit plan from the start. This sounds abstract for a new practice owner, but the financial decisions you make in years 1–5 shape what the practice is worth in years 15–20. How you structure goodwill (personal vs. enterprise), whether you build associate dependence into the revenue base, and whether the practice can operate without you — these are the drivers of sale price and exit options. The dentists who sell for 8× EBITDA started thinking about this 10 years before they sold. See dental practice exit planning guide.
