Dental Practice Exit Planning: The 5-10 Year Runway

The single decision that most determines your retirement outcome is not which investments you hold or when you claim Social Security — it's how much your dental practice sells for and how well you're positioned to deploy those proceeds. The problem: most dentists don't start planning their exit until 12–24 months before they want to close a deal. By then, the biggest value-building levers are already locked in.

This guide is for the dentist who is 5–10 years out from a planned exit. That time horizon is where real leverage lives. The decisions you make now — about your practice structure, your associate strategy, your personal wealth outside the practice, and your tax posture — compound directly into the number at the closing table.

Why 5-10 years matters

A dental practice is valued primarily on its adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization). Buyers — whether individual dentists, regional groups, or DSOs — are paying a multiple of what the business earns as a standalone entity. Typical multiples in 2026:¹

The leverage point: a single-location general practice typically transacts at 3–6×. But if you increase your adjusted EBITDA by $100,000 over the next five years — through overhead reduction, associate revenue, or both — that $100,000 of incremental earnings becomes $400,000–$600,000 of incremental deal value. No investment strategy offers that return on capital deployed.

Conversely, a dentist who runs discretionary personal expenses through the practice, doesn't maintain clean books, and lets overhead creep above 70% will see those $100,000 gains erased in due diligence. Buyers normalize EBITDA, and every undocumented add-back is a potential purchase price adjustment.

The five practice value drivers

Every buyer — from a fellow dentist using an SBA loan to a DSO's M&A team — is evaluating your practice on some version of these five dimensions:

1. EBITDA and EBITDA margin

Raw collections matter less than what falls to the bottom line. Two practices both collecting $1.5M annually can have dramatically different values if one runs at 55% overhead and the other at 70%. The 55% overhead practice might generate $675,000 in adjusted EBITDA; the 70% overhead practice generates $450,000. At a 5× multiple, that's a $1.125M difference in deal value — on the same revenue.

Benchmark overhead by category: staff 25–30%, lab 7–10%, supplies 5–7%, facility 5–9%, marketing 1–3%. If you're materially above any benchmark, identify the driver and address it. Staff costs are the most common culprit — often a compensation structure that was set 10 years ago and has never been benchmarked to production.

2. Revenue trend

A flat or declining collections trend raises a red flag that buyers price into their offer. A consistent 4–6% annual growth rate signals a healthy, sustainable practice that doesn't require heroic production from a single provider. If your collections have been stagnant, identify whether the constraint is new patient flow, capacity, or case mix — and address it before you're in a sale process.

3. Owner dependence

This is the most underappreciated valuation factor, and it is discussed in detail below. A practice where 100% of production is driven by the owner carries more risk to the buyer than one where two associates together produce 40–50% of collections. Owner dependence is also what determines whether a DSO will offer you an extended walk-out obligation — and whether that walk-out is on your terms or theirs.

4. Lease and physical plant

Buyers pay attention to how much practice life is left in your facility. A practice on a month-to-month holdover, in a space with a major buildout deferred, or in a building slated for redevelopment is harder to finance and easier to low-ball. Ideally, you enter a sale process with 5–10 years of lease term remaining (including options), or you own your real estate outright — itself a significant asset that can be monetized separately or retained as a long-term income stream via a self-rental to the buyer.

5. Documentation and systems

A practice that produces clean, normalized financial statements going back three years, tracks hygiene recall rates and case acceptance, and operates on documented clinical and administrative systems sells faster and at better multiples than one that requires extensive buyer due diligence to reconstruct the numbers. Start the documentation habit now.

Owner dependence: the hidden valuation discount

The most common question buyers ask about a solo practice is: "What happens if this dentist gets sick, moves, or retires?" If the answer is "the practice stops functioning," you have an owner-dependence problem that buyers will price into their offer — usually as a reduced multiple or a longer required walk-out period.

Reducing owner dependence is a 3–5 year project. It happens in layers:

• Hire hygienists who can run an independent recall system. If your hygiene department is fully scheduled and producing independently of your chair time, you've separated practice value from your personal production.
• Add an associate, even part-time. An associate producing $400,000 per year eliminates roughly $400,000 of direct owner-dependence from your practice revenue — and may create the platform for a DSO or group buyer to pay a higher multiple. Associates are expensive to recruit and retain, but the valuation math is significant.
• Build patient relationships with the team, not just with you. Recall rates, hygiene completion rates, and case acceptance by non-owner providers are data points that buyers can verify and that support the argument that your patient base isn't purely personal goodwill dependent on you staying.

Building wealth outside the practice

Most dentists who sell a practice discover, in the 12 months before the transaction, that the practice represents 70–85% of their net worth. That concentration is fine during accumulation — the practice is a high-return asset — but it creates a dangerous dependency at exit: your entire financial life hinges on one transaction at one point in time.

The antidote is intentional diversification, started early. Practical strategies:

Max out tax-sheltered accounts every year

The 2026 combined contribution limit for a solo 401(k) with a cash balance plan is $72,000–$265,000+ per year depending on your age and income level — far beyond what most dentists actually contribute. Each dollar sheltered now reduces the fraction of retirement wealth that depends on the practice sale. A dentist who contributes $100,000/year to tax-deferred accounts for 10 years has $1M+ in portable, practice-independent wealth before the exit. Combine a solo 401(k) (2026 limit: $72,000; catch-up at 50+: $8,000; super catch-up 60–63: $11,250) with a cash balance plan for maximum shelter.²

Invest taxable brokerage assets systematically

Every dollar in a taxable brokerage account that grows over 10 years at long-term capital gains rates (0%/15%/20%) is a dollar that didn't ride on the practice's sale price. Dollar-cost averaging into a broadly diversified portfolio creates a liquidity floor — money that isn't locked up in practice equity and is immediately available regardless of what the practice sale brings.

Consider real estate as a parallel asset

Dentists who own their office space enter retirement with a distinct income-producing asset they can lease to the buyer rather than sell. The buyer pays market rent; you collect monthly income (treated as ordinary income but offsetable with depreciation). At some point, you sell the real estate separately — potentially via a 1031 exchange into other commercial property — at long-term capital gains rates. Owning the real estate also gives you negotiating leverage: a buyer who needs to occupy the space can't walk without you. See our dental office real estate guide for SBA 504 financing specifics.

Internal succession vs. external sale: the decision framework

As you get closer to exit, one of the most important strategic decisions is whether to sell internally (to an associate you've trained) or externally (to a third party or DSO). Neither path is universally better — it depends on what you want from the exit.

Year-by-year action timeline

This isn't a rigid schedule — practices vary too much for that. But it's a useful lens for prioritizing effort across the exit runway.

10 years out

• Get a preliminary practice valuation. Understand what drives your multiple and where you sit today relative to the range.
• Review your lease. Do you have enough term remaining (or options) to support a future sale? Negotiate an extension if needed.
• Benchmark overhead by category. Identify the biggest deviations from dental-specific benchmarks.
• Maximize tax-sheltered contributions every year from here forward. Start a solo 401(k) or group 401(k) if you haven't.

7 years out

• Decide whether to pursue an internal succession (associate buy-in) or external sale. If internal, begin the associate search and structure.
• Begin reducing personal expenses run through the practice. Every personal-expense add-back in future due diligence is a credibility risk with buyers.
• Start a cash balance plan if your income supports it ($300K+ net). The compounded shelter over 7 years at contribution rates of $100,000–$200,000/year creates a major retirement asset independent of the practice sale.

5 years out

• Associate, if pursued, should be in place and producing. Monitor production share versus your own.
• Begin building systems documentation. Operational manuals, staff training protocols, recall systems. Buyers pay a premium for a practice that doesn't depend on the owner's tribal knowledge.
• Review your entity structure with a CPA. Is your entity type (S-corp, PLLC, PC) optimal for a sale? The entity conversion window, if needed, is here — not 6 months before you sign a letter of intent.
• Model the tax impact of different sale structures. Run a preliminary scenario: asset sale to individual vs. DSO deal with rollover equity. Know what each scenario nets after federal and state taxes before you receive any offers.

3 years out

• Stop large equipment purchases unless operationally essential. § 179 and bonus depreciation are attractive deductions during ownership but create ordinary income (§ 1245 recapture) at sale. Equipment purchased in year 3 and expensed at 100% creates an ordinary income problem at the closing table.
• Begin Roth conversion planning. In the 2–3 years before the sale, your income may be high but not as high as the sale year itself. Converting traditional retirement balances to Roth at 22%–24% rates is preferable to converting in the sale year at 32%–37%.
• Normalize your financial statements. Three years of clean, auditable P&L statements — with add-backs clearly documented — is the minimum serious buyers expect. Gaps in documentation create due diligence delays and purchase price adjustment risk.

18-24 months out

• Get a formal practice appraisal. This is different from a broker's ballpark estimate — a written, defensible valuation from a credentialed appraiser (AVBCE, ASA) gives you a reference point in negotiations and documentation for your personal goodwill argument if applicable.
• Engage a dental practice attorney and a CPA with transaction experience before you receive any LOI. The worst time to find these advisors is after a DSO sends you a 50-page letter of intent.
• Decide on your post-sale life plan. How much do you need? How long do you want to work? Do you want a walk-out arrangement or a clean break? This informs whether a DSO deal (higher proceeds, longer walk-out) or individual sale (lower proceeds, faster exit) is the right fit.

12 months out

• Finalize sale path. If pursuing an external sale, decide between broker-represented and direct approach to buyers. If DSO, know which platforms are active in your geography and practice size.
• Understand the purchase price allocation negotiation in advance. Non-compete vs. goodwill allocation is worth real money in after-tax proceeds. Have your CPA model the scenario before you sit across from a buyer's attorney.
• Coordinate estimated tax payments with your CPA. A practice sale generating $1M+ in capital gain creates a large estimated tax obligation in the quarter of sale. Underpayment is avoidable with advance planning.

Tax planning in the exit runway

The single largest financial lever in the exit runway isn't practice value — it's after-tax proceeds. Two dentists selling the same practice for the same price can have dramatically different outcomes depending on their pre-sale tax position.

Qualified Opportunity Zone investments

If your practice sale generates a large capital gain, investing the recognized gain into a Qualified Opportunity Zone fund within 180 days of sale defers the original gain until 2026 (current deadline) and potentially eliminates appreciation in the QOZ investment after a 10-year hold. QOZ funds carry illiquidity risk and management fee drag — but for a practice owner with a large gain and a multi-decade horizon for the reinvested capital, they merit evaluation.³

Charitable strategies in the sale year

Donor-advised funds allow you to contribute appreciated assets — or cash from sale proceeds — in the high-income sale year, take a full deduction now, and distribute to charities over multiple years. If you're charitably inclined, this is substantially better than giving in a lower-income year. Qualified Charitable Distributions (QCD) from IRAs let you give up to $111,000 in 2026 directly from your IRA tax-free once you're 70½, satisfying RMD obligations without recognizing income.²

State tax planning

Capital gains tax treatment varies widely by state. California taxes long-term capital gains as ordinary income at up to 13.3%. Texas, Florida, and several other states have no state income tax. If you live in a high-tax state and have flexibility in your timeline, the state tax differential alone can justify deferring a sale by one or two years — or accelerating one. A dentist selling a practice for $2M in California vs. Texas might have a $200,000+ difference in after-tax proceeds on the same deal.
