Short answer: opening a dental practice from scratch — a “de novo” — commonly costs somewhere in the mid-to-high six figures once you add build-out, equipment, and working capital. Buildout and location drive most of it. Starting from scratch gives you full control but a slower ramp; buying an existing practice costs more up front but comes with immediate cash flow.
What does it cost to open a dental office?
Most de novo startups land in the mid-to-high six figures once everything is counted — and it can run higher in expensive markets or with extensive build-outs. The figure isn’t one check; it’s a stack of costs spread across construction, equipment, technology, and the cash you need to survive the early, slow months.
| Component | What it covers |
|---|---|
| Leasehold improvements / build-out | Construction, plumbing, cabinetry — often the largest cost |
| Equipment & technology | Chairs, imaging, sterilization, software, computers |
| Working capital | Payroll, rent, and supplies until collections ramp |
| Initial supplies & inventory | Instruments, consumables, PPE |
| Soft costs | Legal, permits, design, marketing, credentialing |
What drives the cost up or down?
- Number of operatories — more chairs, more build-out and equipment.
- Location and rent — high-cost markets raise nearly every line item.
- Condition of the space — a raw shell costs more than a former dental suite.
- Technology choices — CBCT, CAD/CAM, and mills add capability and cost.
- How much you finance vs. pay in cash.
Startup vs. buying an existing practice
A startup usually costs less up front than buying an established practice, but you build the patient base from zero — expect a slower ramp and a longer path to profitability. Buying costs more and includes goodwill, but you inherit patients, staff, and cash flow on day one. Neither is universally better; it depends on your risk tolerance, capital, and market. Our buying a practice guide covers the acquisition path.
How do dentists finance a startup?
Most use practice-acquisition or startup loans, often with little money down for well-qualified dentists, sometimes via SBA financing. Lenders look at your credit, production history, and business plan. We walk through the lending landscape in financing a practice purchase — much of it applies to startups too.

Starting from scratch is usually cheaper up front, but you build patients from zero and ramp slowly. Buying an established practice costs more (it includes goodwill) but delivers immediate cash flow, patients, and staff. The right choice depends on your capital and risk tolerance.
Many well-qualified dentists finance most or all of a startup through practice-lending programs, sometimes with little money down. Lenders weigh your credit, production history, and business plan. You still need working capital budgeted into the loan to cover the slow early months.
