Verify active patients, payer mix, equipment, and financials before you sign — a step-by-step framework for associate dentists and dental group acquirers.
Acquiring a dental practice involves far more than reviewing tax returns. The real value — and risk — lives in the active patient base, hygiene recall rates, payer mix quality, and the degree to which the selling dentist is personally responsible for production. This checklist covers the five critical due diligence categories every buyer must work through before closing, whether you're an associate dentist using SBA financing or a DSO executing a tuck-in acquisition. Use it alongside a dental-specific CPA, attorney, and practice broker to surface deal-killers early and negotiate from a position of knowledge.
Verify the true size, loyalty, and retention health of the active patient population — the foundation of practice value.
Pull active patient count report from practice management software for the trailing 18 months.
Active patient count (800–1,200 minimum) directly drives recurring hygiene and restorative revenue.
Red flag: Seller quotes 2,000 patients but software shows fewer than 900 seen in 18 months.
Calculate hygiene recall compliance rate — percentage of active patients completing scheduled recare visits.
Recall rates above 75% indicate a healthy, sticky patient base and predictable future revenue.
Red flag: Recall compliance below 55% signals patient attrition and weak front-office systems.
Review new patient flow trends month-over-month for the trailing 24 months.
Consistent new patient volume sustains growth and offsets natural attrition from the existing base.
Red flag: New patient count declining more than 15% year-over-year without clear explanation.
Assess patient demographic concentration — age distribution and geographic proximity to the practice.
Heavily aged or geographically dispersed patient bases carry higher post-acquisition attrition risk.
Red flag: More than 40% of active patients are over age 70 with no younger demographic pipeline.
Reconcile reported collections to actual cash received and normalize owner compensation to confirm true EBITDA.
Reconcile production vs. collections reports from practice software against bank deposits and tax returns.
Gaps between production and collections reveal write-offs, billing inefficiencies, or unreported adjustments.
Red flag: Collections consistently below 90% of production without documented insurance adjustment explanations.
Review accounts receivable aging report — segment balances by 0–30, 31–60, 61–90, and 90+ days.
Aged AR over 90 days is often uncollectable and inflates perceived practice revenue.
Red flag: More than 20% of total AR aged beyond 90 days with no active collection process.
Normalize owner compensation by adding back personal expenses, above-market salary, and one-time costs.
True EBITDA margin of 15–30% is only visible after removing owner-specific financial distortions.
Red flag: Owner compensation normalization swings EBITDA by more than 30%, signaling unreliable financials.
Confirm three years of tax returns match practice management software production and collections totals.
Discrepancies between reported income and software totals suggest cash transactions or bookkeeping issues.
Red flag: Unexplained variances greater than 5% between software collections and tax-reported gross revenue.
Evaluate revenue quality by analyzing insurance contracts, reimbursement rates, and credentialing transferability.
Request a full payer mix breakdown showing percentage of revenue by fee-for-service, PPO, HMO, and Medicaid.
Fee-for-service and strong PPO mix supports higher EBITDA margins and stronger valuation multiples.
Red flag: Medicaid or HMO revenue exceeding 40% of total collections significantly compresses practice value.
Obtain copies of all active insurance contracts and verify current reimbursement rates for top 10 procedures.
Reimbursement rates vary widely by network and directly impact post-acquisition profitability.
Red flag: PPO reimbursement rates more than 25% below UCR fees on high-volume procedures like crowns and composites.
Confirm insurance credentialing is current for all providers and assess transferability to the new owner.
Lapsed or non-transferable credentialing causes revenue gaps of 30–90 days post-closing.
Red flag: Any provider credentialing expired or under audit by a major payer at the time of closing.
Identify any pending insurance contract renegotiations or termination notices from payers.
A pending PPO termination can eliminate a significant revenue stream immediately post-acquisition.
Red flag: Seller unable to produce executed, current copies of contracts for top three payers by revenue.
Assess the physical condition of the practice to quantify deferred capital expenditures and operational readiness.
Conduct a room-by-room equipment inventory including age, brand, service history, and current functionality.
Aging chairs, compressors, and sterilization units require near-term replacement averaging $30K–$80K per operatory.
Red flag: Dental chairs, delivery units, or compressors more than 15 years old with no recent service records.
Verify digital X-ray and imaging capabilities — confirm presence of digital sensors, panoramic, and CBCT if applicable.
Analog X-ray systems require $50K–$150K in digital conversion costs, reducing effective purchase price.
Red flag: Practice still using film-based X-ray with no digital imaging investment in the last five years.
Review the office lease terms — confirm remaining term, renewal options, and landlord consent to assignment.
A lease with fewer than five years remaining and no renewal option creates immediate relocation risk.
Red flag: Lease expires within 24 months of closing with no signed renewal option or landlord cooperation.
Assess practice management software — confirm system, version, data migration feasibility, and support status.
Migrating patient records from unsupported software creates operational disruption and potential data loss.
Red flag: Practice running on end-of-life software with no support contract and no recent data backup documentation.
Evaluate clinical and operational team stability and quantify dependency on the selling dentist's personal production.
Determine what percentage of total collections is personally produced by the selling dentist.
Seller producing more than 80% of collections creates severe key-person risk and revenue loss post-acquisition.
Red flag: Selling dentist accounts for 90%+ of production with no associate dentist or planned transition support.
Review employment agreements, compensation structures, and tenure for all hygienists and clinical assistants.
Hygienists drive 25–35% of practice revenue; losing two or more post-close materially impairs collections.
Red flag: Key hygienists with no employment agreements verbally expressing intention to leave post-transition.
Confirm the seller's post-closing transition commitment — duration, clinical hours, and compensation terms.
A 12–24 month transition employment agreement protects patient retention and smooths operational handoff.
Red flag: Seller unwilling to commit to more than 90 days post-close with no associate already in place.
Verify non-compete agreements exist and are enforceable for the seller and any departing associate dentists.
An unenforceable non-compete allows the seller to open a competing practice within the same patient catchment area.
Red flag: Seller's non-compete covers less than a two-mile radius or fewer than two years in a dense suburban market.

Vetted targets with diligence packages — skip the cold search.
Request a direct export from the practice management software — Dentrix, Eaglesoft, or Carestream — filtered to patients with at least one completed visit in the trailing 18 months. Cross-reference this against hygiene appointment history and recall compliance reports. Do not accept a manually compiled spreadsheet from the seller as your primary source. A count above 1,000 active patients with recall compliance over 70% is a strong foundation; below 800 with declining new patient flow is a material risk that should affect your offer price and structure.
Healthy general dentistry practices typically operate at EBITDA margins of 15–30% after normalizing owner compensation to a market-rate clinical salary of $150K–$250K. Practices with heavy fee-for-service or strong PPO mix in suburban markets often achieve the upper range. Medicaid-heavy or high-overhead metropolitan practices frequently fall below 15%, compressing both value and SBA loan eligibility. Always normalize financials with a dental-specific CPA before accepting a broker's stated EBITDA figure.
Lower middle market dental practices ($500K–$3M in collections) typically trade at 3.5x–6.5x EBITDA. Fee-for-service practices with 1,000+ active patients, strong recall programs, and multiple producers command the upper range. Medicaid-dependent, single-provider practices with aging equipment and declining patient counts trade at the lower end or struggle to attract qualified buyers. DSOs and private equity-backed groups are currently paying premium multiples for clean, fee-for-service practices, which is setting market expectations even for private buyer transactions.
Yes — dental practice acquisitions are among the most SBA-eligible transactions in healthcare services due to predictable cash flows and tangible asset backing. SBA 7(a) lenders focused on dental deals will closely scrutinize three years of tax returns reconciled against practice management software reports, trailing twelve-month collections, debt service coverage ratio (minimum 1.25x), active patient count, and the seller's transition commitment. Lenders are increasingly cautious about Medicaid-heavy practices and single-producer models. Engaging a lender with a dedicated healthcare or dental lending division significantly streamlines approval.
