Dental practices are among the most bankable small business acquisitions in the U.S. Strong recurring hygiene revenue, predictable cash flows, and tangible patient base metrics make lenders comfortable. Most deals combine SBA financing with seller carry, though DSO-affiliated buyers increasingly use equity rollover structures. Understanding your options before approaching a seller puts you in a stronger negotiating position.

Financing Options for Dental Practice Acquisitions

SBA 7(a) Loan

$500K–$3MPrime + 2.75%–3.75% (currently ~10–11.5% variable)

The most common financing tool for associate dentists buying their first practice. SBA 7(a) loans cover up to 90% of the purchase price including goodwill, equipment, and working capital, with repayment terms up to 10 years.

Pros

Low down payment (10–15%) preserves cash for working capital and early practice investments like equipment upgrades
Lenders experienced in dental acquisitions understand goodwill-heavy valuations and active patient count metrics
Can be paired with seller carry for full or near-full deal financing with minimal buyer equity out-of-pocket

Cons

×Personal guarantee required — your personal assets are at risk if the practice underperforms post-acquisition
×Variable interest rates tied to Prime can increase debt service costs if rates rise during the loan term
×Underwriting scrutiny on Medicaid-heavy payer mix or sole-producer practices may result in loan denial or reduced proceeds

Seller Financing (Seller Carry)

$75K–$500K (subordinate note, 10–20% of deal)5–8% fixed, negotiated between buyer and seller

The selling dentist holds a promissory note for 10–20% of the purchase price, typically subordinate to the SBA loan. Often structured as a 3–5 year term paired with a 1–2 year post-close employment agreement to support patient and staff retention.

Pros

Signals seller confidence in practice performance and smooths SBA lender approval by closing the financing gap
Flexible repayment terms can be deferred or tied to production milestones during the transition period
Keeps the selling dentist financially invested in a smooth handoff, reducing key-person departure risk

Cons

×SBA rules restrict seller note terms — it must typically be on full standby for the first 24 months of the SBA loan
×Seller may resist carry if they need full liquidity at close, requiring price concessions or alternative gap financing
×Disputes over earnout triggers or production shortfalls can strain the post-close relationship with the transitioning dentist

DSO Affiliation with Equity Rollover

Partial liquidity event — typically $500K–$2M cash at close plus retained equity stakeN/A — equity transaction; ROI depends on DSO's eventual exit valuation

Dental Service Organizations acquire majority ownership (60–80%) of a practice while the selling dentist rolls 20–40% equity into the DSO entity. A management services agreement handles billing, HR, and ops while the dentist continues producing.

Pros

Provides immediate liquidity while retaining upside through equity rollover in a growing DSO platform
Eliminates administrative burden — DSO handles insurance credentialing, HR, and billing post-close
Attractive for multi-location owners or high-producing solo practices seeking a platform exit at premium multiples

Cons

×Seller gives up operational independence — DSO controls hiring, payer mix strategy, and capital allocation decisions
×Rollover equity value depends entirely on DSO's future performance and private equity exit timeline, which is uncertain
×Medicaid-heavy or single-provider practices rarely qualify for DSO affiliation at favorable multiples

Sample Capital Stack

$1,400,000 (general dentistry practice, $1.8M collections, 22% EBITDA margin, 1,100 active patients)

Purchase Price

~$13,200/month combined debt service (SBA at 10.75% over 10 years + seller note at 6% over 5 years)

Monthly Service

~1.35x DSCR based on $215K normalized EBITDA — comfortably above the 1.25x SBA lender minimum threshold

DSCR

SBA 7(a) Loan: $1,190,000 (85%) | Seller Carry Note: $140,000 (10%) | Buyer Cash Equity: $70,000 (5%)

Lender Tips for Dental Practice Acquisitions

1Work with SBA-preferred lenders who have a dedicated healthcare or dental vertical — they understand goodwill-heavy valuations and won't underwrite a dental practice like a widget manufacturer.
2Pull an active patient count report (seen within 18 months) and hygiene recall compliance rate before approaching lenders — these metrics are the first thing dental-focused underwriters request.
3Normalize owner compensation in your financial model before submitting to lenders. Dentist-owners often run personal expenses through the practice; addbacks must be documented with tax returns and P&Ls.
4If the selling dentist represents 90%+ of production, expect lender scrutiny on key-person risk. A 12–24 month post-close employment agreement in the purchase contract materially improves loan approval odds.

Frequently Asked Questions

Can I buy a dental practice with no money down?

Rarely in true zero-down structures, but combining a 10% seller carry note on standby with an SBA 7(a) loan can reduce your out-of-pocket equity to 5–10%, or roughly $50K–$150K on a $1–2M practice.

How do SBA lenders evaluate a dental practice with heavy Medicaid exposure?

Medicaid-heavy payer mixes (30%+ of collections) raise reimbursement sustainability concerns. Lenders may require higher equity injection, reduced loan proceeds, or may decline the deal entirely depending on the payer concentration.

What DSCR do lenders require for dental practice SBA loans?

Most SBA lenders require a minimum 1.25x debt service coverage ratio using normalized EBITDA. Dental practices with 20%+ EBITDA margins and 1,000+ active patients typically meet this threshold comfortably.

Should I pursue a DSO deal or an SBA loan as an associate dentist buyer?

DSO deals favor sellers seeking partial liquidity and reduced admin burden. As a first-time buyer seeking full ownership and control, SBA 7(a) with seller carry is typically faster, more straightforward, and preserves your operational independence.
