How to Value a Dental Practice: Collections, EBITDA, and What DSOs Actually Pay

A general dental practice is typically worth 55–75% of its annual collections, or (the more precise lens buyers actually transact on) a multiple of its earnings: commonly 1.5–2.5× SDE for an owner-operated practice sold doctor-to-doctor, and 4–7× adjusted EBITDA when the buyer is a DSO or private-equity-backed group. Which lens applies, and where in the range you land, depends on your hygiene mix, active patient base, payer mix, and how much of the production walks out the door when you do.

Here's how each method works, why DSOs pay more, and how to run the numbers on a real practice.

The Percentage-of-Collections Rule (and Its Limits)

The oldest shorthand in dental transitions prices a practice as a share of trailing-twelve-month collections. It persists because it's simple and because decades of doctor-to-doctor sales cluster in a fairly stable band:

The limitation is obvious: collections measure volume, not profit. Two practices collecting $900K can produce wildly different owner earnings depending on staffing, rent, and payer mix. That's why collections percentages work only as a cross-check, while serious buyers, and every lender underwriting the deal, price on earnings.

The Earnings Lens: SDE for Doctors, EBITDA for DSOs

Doctor-to-doctor sales price on Seller's Discretionary Earnings (profit plus the owner-dentist's compensation and perks) because the buying dentist replaces the seller in the chair. Owner-operated practices commonly trade at 1.5–2.5× SDE.

DSO and group acquisitions price on adjusted EBITDA after replacement dentistry cost. They must pay an associate (typically ~25–32% of their production) to produce what you produced, so that cost comes out of earnings before the multiple is applied. On that adjusted base, commonly cited bands run:

This is also why DSO offers look dramatically higher than doctor-buyer offers, but often aren't apples-to-apples: a portion is frequently paid in equity rollover, earnouts, or tied to post-close employment. Discount the headline accordingly.

What Moves a Dental Practice's Multiple

• Hygiene share of production. Hygiene revenue (commonly ~25–35% of a healthy GP practice) recurs without the doctor and transfers cleanly. Buyers pay up for it.
• Active patients and new-patient flow. A growing base of active patients (seen in the last 18–24 months) is the practice's real asset; stagnant recall lists get discounted.
• Payer mix. Heavy PPO write-offs compress margins; strong fee-for-service or well-negotiated PPO mixes support the top of the range.
• Owner clinical dependence. If the seller produces 90% of dentistry and leaves, earnings leave too: the same owner-dependence discount every buyer applies, sharpened by patient loyalty risk.
• Facility and equipment. Modern operatories, digital radiography/CBCT, and an assignable lease (or purchasable real estate) de-risk the transition; a five-op ceiling in a landlocked suite caps growth and the multiple with it.
• Clean add-backs. Continuing-education trips, family payroll, and personal expenses must be documented to count.

A Worked Example

A solo GP practice collecting $900,000:

• Doctor-buyer lens: $295K SDE × 1.8–2.2× ≈ $530K–$650K, about 59–72% of collections, right inside the historical band.
• DSO lens: $113K EBITDA × 4–5× ≈ $450K–$565K cash value, before any equity rollover sweetener.

For a practice this size, a well-run doctor-to-doctor sale competes with or beats a DSO offer. The DSO math starts winning decisively as EBITDA scales past ~$300K+, where multiples expand instead of the earnings base.

Frequently Asked Questions

What is a dental practice worth as a percentage of collections?

Most general practices transact between 55% and 75% of trailing-twelve-month collections, with weaker or highly owner-dependent practices below that band and strong specialty practices sometimes above it. Treat it as a cross-check on an earnings-based valuation, not a substitute.

Why do DSOs pay higher multiples than individual dentists?

Scale and financing: groups aggregate practices, centralize administration, and are valued by their own investors at higher multiples than any single practice, so they can pay 4–7× EBITDA and still create value. But DSO offers usually price post-associate-replacement EBITDA and often include equity or earnout components, so compare the cash-at-close, not the headline.

Does the real estate change the valuation?

The practice and the building are valued separately. Owning the real estate gives you a second asset to sell or lease back; if you rent, buyers need an assignable lease with enough term. A shaky lease discounts an otherwise strong practice.

How far in advance should I prepare a practice for sale?

Ideally 2–3 years: enough time to grow hygiene, document add-backs, associate-proof some production, and let improved earnings show up in the trailing financials that buyers actually price.

Key Takeaways

• Dental practices price on earnings first (commonly 1.5–2.5× SDE doctor-to-doctor, 4–7× adjusted EBITDA for DSO buyers), with 55–75% of collections as the sanity band.
• DSO offers deduct associate replacement cost before the multiple and often pay partly in equity or earnouts; compare cash-at-close, not headlines.
• Hygiene mix, active patients, payer mix, and owner dependence are the biggest multiple movers.
• The percentage-of-collections rule is a cross-check; lenders and sophisticated buyers underwrite earnings.

Whether you're a dentist planning an exit or a buyer weighing a practice against a DSO's term sheet, run the numbers both ways before anyone anchors you. ValueAlpha's healthcare-services valuation normalizes earnings and applies both lenses: run your valuation and know your range before the negotiation starts.
