From SBA-financed asset purchases to DSO equity rollovers, understand every deal structure used in dental practice transactions — and how to negotiate the one that protects your interests.
Dental practice acquisitions follow a relatively consistent playbook, but the right deal structure depends heavily on whether you're an associate dentist buying your first office, a regional group pursuing a tuck-in acquisition, or a retiring practitioner evaluating a DSO affiliation. Most transactions in the $500K–$3M collections range are structured as asset purchases — meaning the buyer acquires the patient records, equipment, goodwill, and lease rights rather than the corporate entity itself. This protects buyers from inheriting undisclosed liabilities and simplifies insurance credentialing. Financing is almost always layered: SBA 7(a) loans cover the bulk of the purchase price, seller carry notes bridge valuation gaps, and transition employment agreements keep the selling dentist producing during the handoff period. DSO transactions introduce additional complexity through partial equity rollovers and management services agreements. Understanding these structures — and their trade-offs — is essential before you sign a letter of intent.

The most common structure for individual buyer acquisitions. The buyer obtains an SBA 7(a) loan (up to $5M) to fund 80–90% of the purchase price, with the selling dentist carrying a subordinated seller note for the remaining 10–20%. The transaction is structured as an asset purchase, transferring patient records, equipment, leasehold improvements, and goodwill. A transition employment agreement requiring the seller to work 12–24 months post-close is standard and often required by SBA lenders to protect the active patient base.
Pros
Cons
Best for: Associate dentists purchasing their first practice in the $500K–$2M collections range where the seller is willing to remain clinically active during the transition period.
DSO Affiliation with Partial Equity Rollover
A dental service organization acquires a controlling interest (60–80%) in the practice while the selling dentist rolls 20–40% of their equity into the DSO's parent entity or a newly formed management company. The DSO assumes back-office operations, billing, HR, and supply chain, while the seller continues clinical production under a clinical services agreement. Earnouts tied to production or collections targets over 2–4 years are common. This structure is designed to maximize total consideration by combining upfront cash with a second liquidity event when the DSO platform recapitalizes or sells.
Pros
Cons
Best for: Established practitioners with $1.5M–$3M+ in collections, strong fee-for-service or PPO payer mix, and multiple providers who want maximum liquidity while retaining clinical income and a second bite at the apple.
All-Cash Asset Purchase (No Seller Financing)
The buyer — typically a DSO, dental group, or well-capitalized individual — pays the full purchase price at closing with no seller note or earnout. In exchange, the seller typically accepts a modestly reduced purchase price (5–10% below market) to reflect the clean, simple transaction. The selling dentist may still be required to execute a short transition agreement of 3–6 months, but longer post-close employment obligations are less common. This structure is most prevalent in DSO platform acquisitions where the buyer has existing credit facilities and can move quickly.
Pros
Cons
Best for: Sellers prioritizing speed and certainty over maximum price, or DSO buyers acquiring practices as tuck-ins into existing markets where the patient base will be absorbed rather than maintained as a standalone entity.

The most common structure is an SBA 7(a)-financed asset purchase with a seller carry note. The buyer secures an SBA loan covering 80–90% of the purchase price, contributes 10% as a down payment, and the selling dentist carries a subordinated note for the remaining 10–20%. This is paired with a 12–24 month transition employment agreement requiring the seller to remain clinically active to protect the active patient base during the handoff. SBA lenders are highly familiar with dental practice acquisitions and typically require 3 years of practice tax returns, production and collections reports from the practice management software, and verification of active patient count.
In a DSO affiliation, the selling dentist receives upfront cash for 60–80% of the practice's value and rolls the remaining 20–40% into equity in the DSO's parent company or a management holdco. The theory is that this rolled equity will be worth significantly more when the DSO platform eventually recapitalizes or sells — the so-called 'second bite of the apple.' Whether this makes sense depends entirely on the DSO's financial health, growth trajectory, and the liquidity timeline. Before accepting a rollover, insist on audited financials for the DSO platform, clarity on the preferred return structure, and realistic comparable DSO exit multiples. For fee-for-service practices with strong EBITDA, DSO valuations often outperform what individual buyers can finance through SBA channels.
A transition employment agreement (TEA) is a post-closing contract requiring the selling dentist to continue working in the practice for a defined period — typically 6 months to 2 years — to introduce patients to the new owner, maintain production levels, and facilitate operational handoff. SBA lenders almost universally require a TEA of at least 12 months when goodwill represents a significant portion of the purchase price, which it does in virtually every dental practice transaction. The TEA should specify the number of clinical days per week, compensation structure (typically a percentage of personal production, ranging from 28–35%), and the dentist's obligations around new patient introductions and staff communication. Vague TEA language is one of the most common sources of post-close disputes in dental acquisitions.
Dental practices in the lower middle market are valued primarily on a multiple of EBITDA (earnings before interest, taxes, depreciation, and amortization), with owner compensation added back to normalize earnings. For general dentistry practices in the $500K–$3M collections range, expect EBITDA multiples of 3.5x–6.5x depending on payer mix, active patient count, number of providers, and equipment condition. Fee-for-service and PPO-heavy practices with 1,000+ active patients and strong hygiene recall programs command the high end (5.5x–6.5x), while Medicaid-heavy or sole-producer practices with aging equipment transact at 3.5x–4.5x. DSO buyers consistently pay at or above the top of this range for practices that fit their geographic footprint, which is why fee-for-service practices with multiple producers often attract DSO interest before going to market.
Three risks are consistently underestimated. First, key-person dependency — if the selling dentist generates 90%+ of collections and leaves after 12 months, the buyer inherits a dramatically different business than they underwrote. Protect yourself with longer TEAs, patient retention warranties, and purchase price adjustments tied to active patient count. Second, insurance credentialing gaps — there is typically a 60–120 day lag between close and the buyer completing credentialing with all PPO networks, during which the practice cannot bill under the buyer's provider number. Budget for this revenue disruption and negotiate bridge billing arrangements with the seller. Third, deferred capital expenditure — aging digital X-ray systems, worn operatory chairs, and outdated sterilization equipment represent real post-close costs that should be reflected in a reduced purchase price or seller credit at closing.
No. Dental practice ownership by non-dentist individuals or corporations is prohibited or heavily restricted in the majority of U.S. states under the corporate practice of dentistry (CPOD) doctrine. States like California, Texas, and New York have strict CPOD laws. DSOs navigate this through management services agreements (MSAs) — the dentist legally owns the clinical entity (the PC or PLLC), while the DSO owns the management company that provides administrative, HR, and operational services in exchange for a management fee. Buyers — particularly those evaluating DSO affiliation — must confirm that the proposed ownership structure complies with their specific state's dental board regulations and that the management services agreement has been reviewed by a healthcare attorney licensed in that state. Regulatory non-compliance can result in loss of licensure and unwinding of the transaction.
