How do you know if a dental practice is a good buy? A buyer's market due diligence checklist

A dental practice is a good buy when four things are true: it produces reliable cash flow after paying a fair salary for the dentist's own clinical work, its patients will stay after the sale, the price leaves room to pay the loan in a bad year, and the market around it can keep supplying new patients. Most buyers check the first three carefully and the fourth barely at all. The market is the one thing you cannot fix after closing, so check it before you make an offer, not during due diligence.

This page is a checklist for the whole decision, with the most detail on the market check. For the full buying process, see how to buy a dental practice, step by step.

The six tests of a good practice

Test	The question	Who checks it
1. Cash flow	After normalizing expenses and paying a market salary for the dentist's work, is there enough left to cover the loan with room to spare?	Dental CPA
2. Patients	Are there enough active patients, with healthy hygiene recall, who are tied to the practice and not only to the seller?	You and your CPA
3. Team and operations	Will key staff stay, and can the practice run without the seller full time?	You
4. Facility and equipment	Will the office need major spending in the first two years?	You, with an equipment technician
5. Lease and legal	Is the lease long enough, assignable to you, and free of surprises? Any liabilities?	Dental attorney
6. Market	Can the area around the practice keep supplying new patients, and is competition rising?	You, with independent market data

Test 6 first: the market check before the offer

Do this before you sign a letter of intent. It takes days, not weeks, and it tells you whether the other five tests are worth paying for.

1. Competition around the practice. Count active general practices within about 5 miles (or a 10 to 15 minute drive in suburbs), from a list checked by a person. Divide the population by that count.

Residents per general practice within 5 miles	How to read it
Under 2,101	Most crowded tenth of suburban and urban US ZIP codes
2,587	25th percentile
3,391	Median suburban or urban ZIP
4,628	75th percentile; above this is the top quarter for room
6,429 or more	Least crowded tenth

Source: Dentagraphics national study of 88,367 hand-verified general practices, October 2026. The US average is about 3,860 residents per general practice. A crowded market isn't a deal breaker for an established practice with loyal patients, but it limits growth and should limit the price you pay for "upside".

2. The competition trend. Ask how many practices opened within 5 miles in the last two or three years, and whether any group or chain offices have arrived. A practice whose collections are flat in a market that is adding offices is losing share.

3. Income, age and children. Compare the area to the practice's patient base and fee model, using Census Bureau American Community Survey data. Dentagraphics' 2026 study found the richest areas are the most crowded (2,380 residents per practice in the top income tenth vs 4,828 in the bottom), and areas with the most children have 37% more room than areas with the fewest.

4. Insurance and payer mix. Does the area's income and employment support the practice's current mix? A fee-for-service practice in an area that is shifting toward PPO or Medicaid will feel pressure.

5. Growth. Steady growth helps a new owner, but growth alone doesn't mean room: the fastest-growing tenth of ZIPs has only about 7% more residents per practice than the fastest-shrinking tenth.

6. Where the patients actually live. Map active patients by ZIP. If most come from outside the 5-mile area, your market test should cover where they live.

7. The space and access. Parking, visibility, signage and any planned road or retail changes nearby.

Tests 1 to 5: the practice itself

1. Cash flow, not collections

Get three years of tax returns, profit and loss statements, and production and collections reports, and reconcile them.
Normalize the seller's personal expenses and pay a market salary for the dentist's clinical work. What remains is what you are buying.
Stress test: can you cover the loan if collections drop 10% to 15% in the first year as some patients leave?
On price: brokers commonly quote general practices at roughly 60% to 80% of annual collections. Treat that as a rough rule of thumb, not a valuation. Two practices with the same collections can have very different profits.

2. Patients

Active patients, and how "active" is defined (seen in 12 months, 18 months, 24 months).
New patients per month for the last two or three years.
Hygiene recall and reappointment rate.
Payer mix and fee schedules.
How much production depends on the seller personally, such as procedures you don't do.

See how to evaluate a dental practice's patient base.

3. Team and operations

Staff tenure, pay compared with local wages, and any benefits you will have to match.
Whether the seller will stay through a transition, and for how long.
Scheduling, hygiene capacity and room to grow without adding space.

4. Facility and equipment

Age and condition of chairs, imaging, sterilization, compressor, vacuum and computers.
Software and data you will inherit.
Building condition and any deferred repairs.

5. Lease and legal

Remaining term and renewal options, so you can pay off the loan before the lease ends.
Assignment to you, rent increases and any relocation clauses.
Restrictive covenant on the seller.
Licensing, regulatory and any pending legal issues.

Signs a practice is a good buy

Cash flow covers a market salary and the loan, with room left in a down year.
New patients have been steady or rising for two or more years.
Residents per practice around it are at or above nearby areas, and few new offices have opened recently.
The area's income, age and payer mix match the practice's model.
Key staff plan to stay and the seller will help with the transition.
The lease runs long enough to pay off the loan and can be assigned to you.

Signs to slow down

Collections are flat while the market around it is adding offices.
Much of production depends on the seller's personal relationships or procedures you don't do.
The lease ends soon or can't be assigned.
Equipment or the building needs major work you didn't price in.
The asking price assumes growth the market can't support.

Who checks what

Your dental CPA checks the numbers, your dental attorney checks the lease and contract, and a lender will run its own review. The market check is usually the one nobody owns: the listing and the valuation describe the practice, not the area around it. Get the market read from a source with no stake in the deal.

Dentagraphics is that kind of source. Our data covers 118,330 US dental practices verified by hand. A Start/Buy membership ($149 per month) includes unlimited address searches and the Practice Marketplace, and a demographer can write a Single-Site Study ($695) on the practice you are considering. We do not broker practices and hold no stake in any deal. See a sample Single-Site Study.

Frequently asked questions

How do I know if a dental practice is a good buy? Check six things: cash flow after a fair salary for the dentist, a loyal active patient base, a stable team, the facility's condition, the lease, and the market around the practice. The market is the one you can't fix after closing, so check it before you make an offer.

What should a dental practice sell for? Brokers commonly quote general practices at roughly 60% to 80% of annual collections, but that is only a rule of thumb. The real value depends on cash flow, patients, the lease and the market. Have a dental CPA review the numbers.

How do I check the market around a dental practice for sale? Count active general practices within about 5 miles from a verified list, divide the population by that count, and compare it with nearby areas and the US average of about 3,860. Then check income, age, payer mix, growth and how many new offices have opened recently.

Is it a bad idea to buy a practice in a crowded area? Not necessarily. An established practice can do well in a crowded market, but growth is harder, so the price should reflect today's cash flow, not hoped-for growth.

What are the biggest red flags when buying a dental practice? Falling new patients, production tied to the seller personally, a short or unassignable lease, equipment that needs replacing, and a market where new offices keep opening.

Should I get an independent market analysis before buying a dental practice? Yes. The listing and the valuation describe the practice; an independent market read tells you whether the area can support it under you, from a source with no stake in the deal.
