How to Evaluate a Dental Practice Before You Buy

A dental practice can look healthy on paper and still become a poor acquisition the day the seller leaves. The reason is simple. Buyers do not purchase historical production. They purchase the chance to preserve future cash flow after patients, staff, schedules, insurance contracts, clinical habits, and goodwill pass to a new owner. That changes the central question.

The issue is not what percentage of collections the practice is worth. The issue is how much dependable cash flow will remain after normal operating expenses, debt service, reinvestment, and fair compensation for the buyer’s clinical work. That is the number that matters.

The first mistake is anchoring on collections. Two practices may each collect $1 million, yet one may produce $350,000 of transferable owner benefit while the other produces only $150,000. A revenue percentage may help as a rough market check, but it cannot determine value by itself.

The second mistake is paying the seller for the buyer’s future work. Brokers and sellers often point to procedures that could be added, hours that could be expanded, unused operatories, stronger marketing, better case acceptance, or new PPO participation. Those opportunities may be real, but they belong mostly to the buyer because the buyer must supply the capital, labor, leadership, and risk required to create them.

A plan is not a list of verbs. “Add implants,” “join insurance,” and “market harder” are not strategies until they include demand, reimbursement, staffing, cost, timing, capacity, and a downside case.

The third mistake is assuming a cheap practice is a safe practice. A $150,000 acquisition with weak patient demand, old systems, idle operatories, and limited cash flow may be more dangerous than an $800,000 practice with stable earnings and a full schedule. Low debt does not erase lost associate income, working capital needs, equipment replacement, or slow growth.

The best initial review begins with three years of tax returns, profit and loss statements, production, adjustments, collections, staffing costs, hygiene activity, payer mix, procedure mix, lease expense, equipment, and demographics. These reports are not due diligence. They are triage. Their purpose is to decide whether the opportunity deserves deeper investigation.

Production is not revenue. Gross production reflects the office’s stated fees. Adjusted production subtracts contractual write offs and other adjustments. Collections are the money received. Tax returns, profit and loss statements, bank deposits, and practice management reports should tell the same basic story after timing differences are explained.

Profit also requires interpretation. Seller tax returns may include personal expenses, family payroll, retirement contributions, related party rent, depreciation, interest, and one time costs. Those expenses may need normalization.

Normalization must work both ways. Buyers often search aggressively for expenses they can add back, yet ignore costs the next owner will inherit. Market wages, equipment replacement, software, cybersecurity, compliance, staffing shortages, deferred maintenance, and management time may all reduce the apparent cash flow. An add back is valid only when the expense will truly disappear.

The buyer must also separate return on ownership from compensation for clinical labor. If a practice leaves $250,000 after operating expenses, that does not mean the owner is earning a passive $250,000 return. Much of that amount may simply compensate the dentist for preparing crowns, performing exams, managing emergencies, and leading the team. The economic benefit of ownership is what remains after assigning fair value to the buyer’s clinical and management work.

Patient counts deserve the same skepticism. “Active patient” can mean anyone seen in the past 12, 18, 24, or 36 months, or simply anyone whose chart was never inactivated. A buyer should calculate unique patients seen during several defined periods, then compare those counts with completed prophylaxis, periodontal maintenance, scaling and root planing, comprehensive exams, limited exams, and future appointments.

The hygiene department is more than a production category. It is the practice’s recurring patient infrastructure. It reveals retention, reappointment discipline, periodontal philosophy, doctor exam opportunities, and future restorative demand. Whether radiographs are credited internally to the dentist or hygienist matters far less than using one consistent definition and understanding the total economics of each patient.

The production by procedure report may be the fastest window into the clinical personality of the practice. It shows whether revenue depends on crowns, fillings, hygiene, emergency care, specialty procedures, or a narrow set of high value cases. It also helps the buyer compare the seller’s clinical profile with the buyer’s own abilities.

That comparison is critical. A seller producing $1.2 million in three days through complex restorative dentistry may not be replaceable by a buyer whose experience is primarily bread and butter dentistry. Historical production only transfers when the buyer can reproduce the diagnosis, speed, treatment presentation, delegation, scheduling, and clinical execution behind it.

Referral leakage can be an opportunity, but only some of it is recoverable. A report showing endodontic, surgical, or implant referrals does not mean every patient will remain in house. Some already trust a specialist. Some cases require equipment, training, sedation, staffing, or call coverage. Others are appropriately referred. The useful number is not how many procedures left the office. It is how many eligible cases the buyer can realistically diagnose, present, accept, complete, and profitably deliver.

Demographics provide context, not destiny. A favorable population to dentist ratio may be misleading if the service area is poorly defined, nearby dentists work part time, patients commute, or local practices differ greatly in capacity. Population growth matters, but growth does not guarantee that new residents will choose the practice, accept its fees, or carry favorable insurance.

The better questions involve actual patient origin, drive times, household income, employer base, insurance coverage, housing development, traffic patterns, cultural fit, competition, and daytime population.

Location also includes the street and the internet. Visibility, parking, signage, reviews, website traffic, phone numbers, domain ownership, online scheduling, and the Google Business Profile may all influence new patient flow. These assets should be identified clearly in the purchase agreement because digital goodwill does not transfer automatically.

The lease can determine whether the rest of the goodwill survives. A practice tied to a location has little long term value without secure occupancy. The buyer should review assignment rights, renewal options, rent increases, personal guarantees, relocation clauses, maintenance obligations, signage, exclusivity, and landlord consent. The existing lease should be treated as reality unless a new agreement is signed.

Staff continuity is equally important. A practice may depend heavily on one office manager, one hygienist, one associate, or one front desk employee who understands every payer, patient, and problem. A strong historical profit can unravel quickly if that person leaves after closing.

The buyer should also examine treatment liabilities. Incomplete cases, prepaid dentistry, memberships, warranties, remakes, aligner cases, open implant treatment, patient credits, refunds, and insurance recoupments can become the new owner’s burden even though the seller collected the original revenue.

Working capital is another common blind spot. Payroll, rent, supplies, lab bills, software, insurance, marketing, loan payments, and personal living expenses continue before every new dollar of production becomes cash. Financing the purchase price without financing the transition is incomplete planning.

A small practice can still be an excellent acquisition. It may provide equipment, staff, patients, location, reputation, and immediate revenue for less than the cost of a startup. But the buyer must treat it as a hybrid between an acquisition and a startup. Growth assumptions should be tested through new patient demand, unscheduled treatment, phone conversion, referral patterns, capacity, and local development.

A large practice can also be riskier than it appears. Revenue may depend on procedures the buyer cannot perform, treatment planning the buyer will not continue, a seller with unusually strong personal relationships, or overhead the buyer cannot control.

The practical test is straightforward. Verify collections across tax returns, accounting reports, practice software, and deposits. Review monthly trends when annual totals hide decline. Define the patient base by actual visits and procedures. Compare the seller’s production with the buyer’s clinical ability. Inspect the lease, staffing, payer contracts, equipment, accounts receivable, and incomplete treatment. Then model what happens if collections fall, staff leave, or growth takes twice as long as expected.

A good acquisition should not require every optimistic assumption to come true. When the seller walks out the door, what exactly are you certain will remain?
