Acquiring a dental practice is the most common path to ownership for dentists who want an established patient base and immediate cash flow rather than a de novo startup. Done well, a dental practice acquisition is one of the most reliable investments in professional practice, a growing asset with strong cash flows and a patient base that transfers well with the right transition management. Done poorly, it becomes an overpriced purchase of a book of business that does not transfer.
This guide covers how dental practices are valued, what due diligence should cover, how to structure the deal, and the most common mistakes first-time buyers make.
How Dental Practices Are Valued
Dental practices are typically valued using one or more of three methods:
- Percentage of gross collections: The most common rule of thumb is 60% to 80% of the trailing 12-month collections. A practice collecting $1,200,000 might list at $720,000 to $960,000. This method is simple but ignores profitability, because two practices with the same collections can have dramatically different overhead structures and actual earnings.
- Multiple of adjusted EBITDA: More financially rigorous. Adjusted EBITDA (collections minus all operating expenses, with doctor compensation added back) multiplied by a factor of 2.5x to 4.5x depending on practice quality. This accounts for overhead efficiency and produces a more defensible valuation for high- or low-overhead practices.
- Asset-based valuation: Accounts for the value of tangible assets, such as equipment and leasehold improvements, separately from goodwill. Most relevant for practices with significant recent capital investment or for practices where goodwill is low (high patient attrition, weak collections).
In most private practice sales, the dominant value driver is goodwill: the patient base, recall system, and established referral relationships. Tangible asset value is secondary. This is why patient retention post-transition is the critical variable. If the patient base does not transfer, the buyer has paid for goodwill that was never received.
What Drives Practice Value Up or Down
Value drivers (positive)
- High active patient count with strong recall compliance
- Collections rate above 97%
- Strong payer mix (high fee-for-service or PPO percentage, limited Medicaid)
- Modern equipment and technology (digital X-ray, CAD/CAM, CBCT)
- Experienced, stable staff who intend to stay post-sale
- Long-term lease in place with renewal options
- Low dentist-patient dependency (patients comfortable seeing multiple providers)
Value detractors (negative)
- Outdated equipment requiring near-term capital replacement
- High dentist-patient dependency (patients loyal specifically to the selling doctor)
- Short remaining lease with uncertain renewal
- Declining active patient count over the past 3 years
- Collections rate below 95%
- Heavy Medicaid payer mix
- Pending insurance contract issues or credentialing complications
Due Diligence: What to Examine Before Closing
A dental practice acquisition due diligence process should cover:
Financial due diligence
- 3 years of practice tax returns (verifying reported collections against bank deposits)
- Trailing 12-month collections and production by month (verify no seasonal anomalies or recent decline)
- Accounts receivable aging report (what sits 90+ days old and why)
- Overhead breakdown by category vs. benchmark
- Doctor compensation structure and add-backs claimed in the adjusted EBITDA calculation
Operational due diligence
- Active patient count (patients with an appointment in the last 18 months)
- New patient count per month over the past 12 months (look for declining trend)
- Unscheduled treatment backlog
- Hygiene reappointment rate
- Staff tenure, compensation, and intent to remain post-sale
- Lease terms: remaining term, renewal options, assignment clause
Clinical due diligence
- Equipment condition and age (commission an equipment inspection)
- Chart audit of 20 to 30 randomly selected patient records for documentation quality and treatment planning patterns
- Infection control compliance review
- OSHA and regulatory compliance status
Deal Structure: Asset Sale vs. Stock Sale
Most dental practice acquisitions are structured as asset sales, where the buyer purchases the assets of the practice (equipment, patient records, goodwill, supplies) rather than the corporate entity itself. Asset sales are preferable for buyers because they limit liability exposure to prior activities of the seller and allow the buyer to step up the tax basis of acquired assets.
Key elements of the purchase agreement to review carefully with a dental-specific attorney:
- Non-compete agreement: The seller should agree not to practice within a defined radius for 3 to 5 years. Define the radius carefully relative to the actual patient draw area of the practice.
- Transition assistance period: The number of days and the patient introduction protocol for the seller to introduce the buyer to existing patients. 30 to 90 days is typical, and more is almost always better.
- Accounts receivable allocation: Who retains the right to collect pre-sale AR and for how long.
- Earnout provisions: Some deals include an earnout tied to patient retention, where the purchase price adjusts if the active patient count drops below a threshold in the first 12 months. This protects the buyer but complicates the deal structure.

Frequently Asked Questions
What is the average selling price of a dental practice?
Most general dentistry practices sell in the range of $400,000 to $900,000, with significant variation based on location, collections, payer mix, and facility quality. Practices in high-cost-of-living markets or specialty practices (orthodontics, oral surgery) can sell for $1,000,000 to $3,000,000 or more. The relevant metric is not the absolute price but the multiple of collections or adjusted EBITDA relative to practice quality.
How long does it take to buy a dental practice?
From letter of intent to close typically takes 60 to 90 days: 30 to 45 days for due diligence and financing approval, then 15 to 30 days for legal documentation. If the landlord of the seller must consent to lease assignment, that process can add 2 to 4 weeks. Plan for 90 days minimum from LOI to operational control.
Can the price of a dental practice be negotiated?
Yes. Listed prices are starting points. The most defensible negotiating leverage comes from due diligence findings: equipment requiring near-term replacement, declining new patient trends, AR aging issues, or short remaining lease terms all justify purchase price adjustments. A practice appraiser on the buyer side provides a defensible counter-valuation when the asking price does not align with what the financials support.
