A practical guide for orthodontists who want to understand what their practice is worth, and what to do with that number.
Every orthodontist eventually asks the same question, whether they’re five years from retirement or five years into ownership: what is my orthodontic practice actually worth?
The instinct is to treat that question as something you only need answered when you’re ready to sell. That’s a mistake. Valuation isn’t a transaction event. It’s a diagnostic tool. Understanding what drives your practice’s value and what erodes it tells you where to focus your time long before a buyer ever enters the picture. It also protects you from a specific kind of regret: making decisions about your practice’s future using a number you never actually verified.
This guide breaks down the process of orthodontic practice valuation: how to calculate orthodontic practice value, what factors move that number up or down, and why the figure on a valuation report rarely matches what you walk away with.
The Three Primary Valuation Methods
Whether you call it a valuation or an orthodontic practice appraisal, the process typically follows one of a few approaches, depending on practice size, structure, and the type of buyer involved.
EBITDA multiple.
This is the standard approach for most mid-sized to larger practices, particularly in transactions involving DSOs, OSOs, or other institutional buyers. EBITDA (earnings before interest, taxes, depreciation, and amortization) represents the practice’s normalized cash flow: what it actually generates once accounting adjustments and owner-specific expenses are stripped out. A buyer applies an orthodontic practice EBITDA multiple to that figure to arrive at an enterprise value.
The specific multiple applied varies significantly based on practice size, growth trajectory, geographic market, doctor transition plans, and overall deal structure. Multiples also shift with broader market conditions and buyer appetite, which means any number you’ve heard quoted, from a colleague, a conference, or an unsolicited offer, may not reflect what your practice would actually command today. This is a conversation to have with an advisor who tracks current market activity, not a figure to anchor on from memory.
Seller Discretionary Earnings (SDE).
This method shows up most often in smaller, single-doctor practice transactions, particularly with individual buyers rather than institutional ones. SDE starts from a similar place as EBITDA but adds back the owner’s compensation and certain discretionary or personal expenses run through the practice, producing a figure that reflects the total financial benefit available to a single owner-operator. A multiple is then applied to that number, typically a smaller multiple than what’s used for EBITDA, since SDE already accounts for owner pay in a way EBITDA does not. Because SDE assumes a single working owner, it tends to fit less well once a practice has multiple doctors or a more complex management structure.
Percentage of collections.
Smaller practices, particularly single-doctor offices without significant scale, are sometimes valued as a percentage of trailing annual collections instead. This method is simpler to calculate but less precise, since it doesn’t account for profitability, only revenue. Two practices with identical collections can have very different values if one runs efficiently and the other carries excess overhead.
None of these methods is inherently better. The right one depends on your practice’s size, your profitability relative to revenue, and who’s likely to be on the other side of the table.
What Actually Drives Your Practice’s Value
The valuation methodology is just the formula. The inputs are where the real work happens, and where doctors have the most influence over their own numbers.
Profitability and margin.
This is the largest lever. A practice generating strong EBITDA relative to collections signals operational discipline, and buyers pay for that. Overhead creep, inefficient scheduling, and underutilized chair time all suppress this number quietly, often without the owner noticing year over year.
Growth trajectory.
A practice with three years of flat or declining case starts is valued differently than one with consistent growth. Buyers are pricing in the future, not just the past.
Doctor dependency.
If the practice’s success is entirely tied to one doctor’s chair time and personal relationships with patients, that’s a risk to a buyer, not an asset. Practices with associate doctors, cross-trained staff, and systems that don’t rely on any single person tend to command stronger valuations.
Patient demographics and case mix.
New patient volume, case complexity, and payer mix (insurance versus self-pay, for example) all factor into how predictable future revenue looks.
Facility and lease terms.
A modern, well-located practice with a favorable lease is worth more than an identical practice operating out of a dated space with an unfavorable one, even if current production is similar.
Team stability.
Staff turnover is a red flag in any valuation conversation. A stable, trained team signals that the practice will continue running smoothly through a transition. High turnover suggests the opposite.
Systems and documentation.
Clean financials, documented processes, and organized patient records make due diligence faster and reduce perceived risk. Disorganized books don’t just slow down a sale. They actively suppress the number a buyer is willing to offer, because uncertainty gets priced in as risk.
Most of these factors are within your control years before you ever plan to transition. That’s the real value of understanding valuation early: it turns an abstract future number into a set of concrete, present-day decisions.
The Gap Between Your Valuation and Your Actual Payout
This is the part that catches many practice owners off guard. The number on a valuation report is not the number that lands in your account.
Several structural elements typically stand between the two:
Deal structure.
Cash at close, earnouts tied to future performance, seller financing, and equity rollovers can all make up portions of a total deal value. A headline number that sounds strong can include a substantial share that’s contingent, delayed, or paid in equity rather than cash.
Transaction costs.
Legal fees, accounting fees, and broker or advisor commissions all come out of the proceeds.
Tax treatment.
How a deal is structured, asset sale versus stock sale, for example, has significant tax consequences that can substantially change your net outcome. This is not a place to guess; it requires a tax advisor who understands practice transitions specifically.
Working capital adjustments and holdbacks.
Buyers often adjust final proceeds based on accounts receivable, outstanding liabilities, or a holdback reserved against post-close claims.
Non-compete and transition requirements.
These aren’t dollar figures on the surface, but they affect the real value of the deal to you personally: how long you’re required to stay, what you’re restricted from doing afterward, and whether the terms match what you actually want your next chapter to look like.
The takeaway isn’t that valuation numbers are meaningless. It’s that a valuation is a starting point for a negotiation, not a guarantee of what you’ll actually receive. Any serious transition conversation needs to move past the headline number into deal structure specifics.
How Valuation Works Differently in a Partnership Model
Traditional sale valuation assumes a clean, one-time transfer: your equity for their cash, full stop. A partnership model changes that calculation because it isn’t structured as a single, terminal exchange.
At Corus Orthodontists, the practice’s EBITDA still forms the basis for calculating value, but the transaction exchanges that value for a combination of cash and equity in the broader network, rather than converting it entirely into a lump sum. Doctor-Partners retain a meaningful ongoing stake, and the value of that stake is tied to the performance of the network they’re now part of, not just the practice they built individually.
This changes what “valuation” actually means in practice. Instead of asking only “what is my practice worth today?,” a Doctor-Partner is also asking “what is the network I’m joining worth, and where is it headed?”
Corus was founded by orthodontists in 2019 specifically to keep the majority of ownership in doctors’ hands, and today spans 65+ Doctor-Partners across more than 75 locations in 12 U.S. states and 5 Canadian provinces, collectively treating more than 60,000 patients a year. That scale matters to the valuation conversation in a way a standalone practice sale doesn’t need to account for: the value you’re receiving is partly a claim on the future performance of a much larger, growing organization.
It also means the operational factors that drive value (profitability, growth trajectory, systems, team stability) matter just as much after the transaction as before it, since your equity’s value continues to move with the practice and the network going forward. Selling out ends that relationship. Buying in extends it.
Questions to Ask Before Any Valuation Conversation
Before you request a formal valuation or engage with a potential buyer, a few questions will help you interpret whatever number comes back:
Who performed this valuation, and what’s their frame of reference?
A valuation from a party with an interest in the outcome (a buyer, for instance) should be treated differently than one from an independent advisor.
Is this a cash number or a total deal number?
Revisit the deal structure question above before treating any figure as what you’d actually receive at close.
What’s driving my multiple relative to others in my market?
Understanding your specific inputs (profitability, growth, doctor dependency, and so on) tells you whether your number reflects strong fundamentals or a favorable moment in the market that may not last.
What happens to this value if I do nothing for the next two years?
Some valuation drivers erode with inaction: aging systems, flat growth, rising doctor dependency. Others compound in your favor. Knowing which category you’re in tells you whether to act now or keep building.
Am I valuing an exit or an entry?
A traditional sale valuation and a partnership valuation answer different questions. Knowing which one you actually want changes what “a good number” even means.
Do I have the full picture, or just the headline?
Ask specifically about deal structure, tax treatment, and contingencies before treating any number as final.
Your Number Is a Starting Point, Not a Verdict
A valuation tells you where your practice stands today. It doesn’t tell you what you should do with that information, and it definitely doesn’t account for what you actually want your next chapter to look like.
For some doctors, a strong valuation is the green light for a clean exit, and that’s a perfectly reasonable outcome. For others, the same number is more useful as a diagnostic: a signal of where the practice is strong, where it’s vulnerable, and what would happen to that value if it were part of something larger instead of standing alone.
Either way, the number is only as useful as the context around it. Get that context before you make a decision you can’t undo.
