Dental practice listings look clean on paper. Profitable. Established. Recession-resistant patient base. Then you see the asking multiple and assume it works like buying any other small business.

It does not.

And the first place most buyers go wrong is trusting the SDE number the broker hands them. That number is almost always inflated. We typically discount broker-presented SDE by 15% to 50% before running any real analysis, because once you strip out the aggressive add-backs and normalize for what the business actually produces in cash flow, the economics look different. Sometimes a little different. Sometimes the whole deal falls apart.

Dental practices trade on their own terms, with their own risk factors, and if you walk in using generic acquisition math you will either overpay or pass on something that actually works. Here is how the numbers move on dental deals.

What “SDE Multiple” Means in a Dental Deal

Seller’s discretionary earnings is the economic output of the business after adding back the owner’s salary, personal expenses, depreciation, amortization, and one-time costs. In theory, it represents what the business puts in your pocket as the owner-operator.

In practice, that number needs serious scrutiny before you build anything on it.

The SDE multiple is how the market prices that earnings stream. A practice showing $400K in SDE listed at 3.5x is priced at $1.4M. The multiple reflects risk, growth potential, patient attrition expectations, and how easily you can replace the selling dentist.

For dental specifically, the seller’s personal production percentage matters more than almost anything else. If the departing dentist generates 80% of collections, that is a fundamentally different risk profile than a multi-provider group where any single person represents 25% of revenue. The multiple has to account for that gap, and most listing prices do not.

One more thing worth understanding early: the distinction between collections and production matters more in dental than in most industries. Write-offs on insurance-negotiated rates can be substantial. When a broker quotes you gross production numbers, you need to know how much of that actually turns into collected revenue. Build your SDE off collections, not production.

Where Dental SDE Multiples Actually Land

Dental practices typically trade between 2.5x and 4.5x SDE. Most competitive deals land in the 3x to 4x range.

The spread is wide because dental is not a monolith. Here is how it breaks down:

Solo practices, dentist-dependent: 2.5x to 3.2x. The selling doctor is the practice. Patient loyalty is personal. Collection risk after the transition is real. The lower multiple compensates for all of that.

Established practices with meaningful hygiene revenue: 3x to 3.8x. Hygiene is predictable, recurring revenue that does not walk out the door when the dentist does. Lenders like it. Buyers pay more for it. And they should.

Multi-provider or group practices: 3.5x to 4.5x. Reduced key-person risk. Often have systems and staff infrastructure already in place. More institutional in character. Buyers compete harder for these, which pushes pricing toward the top of the range.

Specialty practices (ortho, oral surgery, perio): 3.8x to 5x or higher. Specialty revenue is durable, high-margin, and referral-driven. Different buyer pool entirely. These often draw DSO interest, which pushes multiples up beyond what an individual buyer can justify on cash flow alone.

These ranges reflect what actually clears the market on completed transactions. Brokers sometimes push listings above this band, particularly on seller-advised deals where emotions run high. Know the ceiling before you make an offer.

How SBA Underwriting Sees Dental Multiples

An SBA 7(a) loan will finance up to 90% of a dental acquisition, but the lender does not care what the broker says the practice is worth. They care about one thing: can you service the debt from actual cash flow.

The number most lenders will reference is 1.25x DSCR. That is their minimum threshold, not a target, and from our perspective it is inadequate. A deal at 1.25x has almost no margin for any revenue dip, any unexpected expense, any transition friction at all. We have watched buyers get into trouble at that level.

We target 2x DSCR as a starting point. Our floor is 1.5x, and even that assumes we have modeled in realistic synergies. Below 1.5x, the deal needs to be restructured or renegotiated before it goes to the lender.

Here is the math on a straightforward deal. Say you are looking at a solo practice doing $1.8M in collections and $520K in SDE (after you have done your own reconstruction, not the broker’s number), listed at 3.5x or $1.82M. With 10% down ($182K), you are borrowing roughly $1.64M. At a 10-year SBA term and current rates in the 10% to 11% range, annual debt service runs approximately $265K to $280K.

$520K divided by $270K in debt service gets you to roughly 1.9x DSCR. That clears underwriting and gives you real breathing room.

Now take the same practice listed at 4.2x, or $2.18M. Same 10% down ($218K), borrowing $1.96M. Debt service climbs to around $320K. DSCR drops to 1.6x. Still passes, but your margin is thinner and you are one bad quarter away from stress.

Push it to 5x and your DSCR falls below 1.25x on most scenarios. The deal does not get done with SBA without a larger down payment or a meaningful seller note.

This is why the multiple ceiling on SBA-financed dental deals is not arbitrary. The math enforces it.

So that covers the financing mechanics. But there is a structural tool most buyers underuse.

The Seller Note and How It Shapes What You Can Pay

A seller note is one of the most useful tools in a dental deal.

In a standard SBA acquisition, we structure the seller note on full standby for 10 years at 0% interest. Zero payments. Zero interest. For the entire SBA loan term. The note counts as equity from the lender’s perspective, which means it reduces your required cash at close. We get this structure on over 90% of our transactions. It is not a special favor. It is how these deals should work.

For dental specifically, seller notes serve a second function: they keep the selling dentist aligned through the transition. A dentist carrying paper has every reason to introduce you to patients properly, help you retain staff, and make sure the handoff is clean. That alignment is worth real money in a dental practice where patient relationships are everything.

A reasonable seller note on a dental deal runs 5% to 15% of purchase price. More than that and the lender may read it as a signal the seller has concerns about value. Less than that and you lose the alignment benefit (and the equity credit).

When you are negotiating the dental practice SDE multiple, the note is a legitimate lever. A seller willing to carry a 10% note on full standby often justifies paying 0.2x to 0.4x more on the multiple compared to an all-cash deal.

Working Capital: The Line Item Most Dental Buyers Forget

You closed the deal. Congratulations. Now you need cash to actually run the practice.

Working capital covers payroll for your hygienists and front desk staff, supplies, lab fees, insurance billing float (which in dental can stretch 30 to 60 days on some claims), and any marketing spend you need to retain patients through the transition. It is not optional.

We advise buyers to budget 2 to 6 months of operating expenses as working capital, either funded through the SBA loan structure, a separate line of credit, or personal reserves. The exact number depends on the practice’s expense base and how much insurance revenue you are collecting versus fee-for-service.

If your entire deal model accounts for the acquisition price, the down payment, and the SBA debt service, but ignores the cash you need on day one to keep the lights on, you have a gap that will cause real problems within the first 90 days.

What Kills Dental Deals at Underwriting

Lenders decline dental acquisitions for predictable reasons. Knowing them before you spend six weeks in diligence on a deal that was never going to close is worth your time.

Revenue concentration in the selling doctor. If one dentist drives more than 60% to 70% of collections, most lenders want a meaningful transition period built into the deal. Some require the seller to stay on as an associate for 12 to 24 months. If the seller refuses, the lender gets nervous. Justifiably.

High patient attrition from prior ownership changes. A practice that changed hands two years ago and has already shed 20% of its active patient base tells a story. Pull the patient ledger trend before you get attached to any number.

Lease term mismatch. SBA requires the lease term to match or exceed the loan term. A 3-year remaining lease with no renewal options on a 10-year loan is a problem. Get the lease assignment or extension negotiated before you submit to the lender. Not after. After is too late.

Add-backs that do not survive scrutiny. The seller’s CPA may have added back personal expenses or one-time items that inflate SDE well beyond what the business actually generates. Underwriters strip questionable add-backs without asking permission. If the deal only works at the listed multiple because of $80K in add-backs that a lender rejects, you built on sand.

Work with your own CPA to reconstruct the financials independently. Do not trust anyone else’s SDE number. That applies to the broker, the seller, and especially to any seller-prepared “recast” P&L.

How to Evaluate a Dental Practice SDE Multiple Before You Offer

Price is one data point. Here is the framework we use to determine whether a dental practice SDE multiple makes sense for a given deal.

Step 1: Reconstruct the SDE yourself. Get three years of tax returns and three years of P&Ls. Add back owner compensation, owner benefits, non-recurring expenses, and depreciation. Reconcile against collections, not gross receipts. And discount what the broker gave you by 15% to 50% as your starting assumption. If your independent reconstruction lands close to the broker’s number, great. But start skeptical.

Step 2: Run the debt service model at 10% down. Calculate annual debt service at current SBA rates on a 10-year term. Include working capital needs in your total funding requirement. Divide reconstructed SDE by total annual debt obligations. If you are not clearing 1.5x DSCR, the price does not work without renegotiation or a larger injection.

Step 3: Identify the key-person risk. What percentage of collections does the selling dentist personally produce. What is the transition plan. How long has the associate staff been in place. These factors determine how much of that SDE you will actually retain post-close.

Step 4: Benchmark the multiple against collections. Most well-run dental practices also trade at 60% to 85% of annual gross collections as a secondary valuation check. If the SDE multiple implies a collections multiple above that band, press on it. Hard.

Step 5: Price the intangibles honestly. Location, practice age, equipment condition, patient management system, specialty mix. A 30-year practice with fully depreciated equipment in a growing suburb is not the same deal as a 5-year-old startup in a saturated urban market, even if both show identical SDE. They do not deserve the same dental practice SDE multiple.

Frequently Asked Questions

What is a fair SDE multiple for a dental practice?

Most dental practice acquisitions clear between 3x and 4x SDE for general dentistry. Hygiene-heavy practices with lower key-person risk trade toward the higher end. Solo practices where the departing dentist drives most production trade lower, typically 2.5x to 3.2x. Specialty practices often command 4x to 5x or higher depending on the buyer pool and whether DSOs are competing. But remember, the multiple only means something if the underlying SDE number is real.

Can you use an SBA loan to buy a dental practice?

Yes. Dental practices qualify for SBA 7(a) financing, and it is one of the most common ways buyers fund these acquisitions. The loan covers up to 90% of the purchase price, with a minimum 10% equity injection from the buyer. The key underwriting test is debt service coverage. The deal structure, including any seller note and working capital allocation, factors into how the lender calculates it. SBA loan maximums are $5M, which covers the majority of general dentistry deals.

Why do lenders care about the selling dentist’s production percentage?

Lenders underwrite your ability to repay from the business’s future cash flow. If the departing dentist generates 80% of collections, there is material risk those collections do not fully transfer to you or a new provider. High seller-dependence increases the probability of revenue decline post-close, which is exactly the scenario lenders try to avoid. It often results in requirements for a transition period, an adjusted deal structure, or both.

How does a seller note affect the dental practice multiple I can pay?

A seller note counted as equity by the lender reduces the SBA loan amount, which lowers your debt service burden. That improved DSCR gives you room to pay a slightly higher multiple while still clearing underwriting. The full standby structure (zero interest, zero payments during the SBA term) is particularly favorable and is what we structure on the vast majority of deals. A well-structured note often allows buyers to justify 0.25x to 0.5x more on the multiple than they could otherwise support.

What add-backs are acceptable when calculating dental practice SDE?

Standard acceptable add-backs include owner compensation (salary plus distributions), personal health insurance paid through the practice, vehicle and phone expenses that are personal in nature, depreciation and amortization, and genuinely one-time expenses like a major equipment repair or legal settlement. Lenders reject recurring discretionary expenses without clear owner ties, above-market wages paid to family members lacking justification, and any add-back requiring optimistic future assumptions. When in doubt, leave it out of your model.

Thinking About Buying a Dental Practice?

Dental acquisitions are one of the more reliable paths to owning a profitable business with SBA financing. The recurring revenue model, defensible cash flows, and established patient relationships make the asset class attractive. But the valuation mechanics are specific enough that generic acquisition math leads buyers astray, sometimes badly.

Regalis Capital advises buyers through the full acquisition process. That means identifying which dental practices are actually priced to clear SBA underwriting, structuring the seller note and working capital, and managing the lender relationship through to close.
