How to Value an Orthodontic Practice in 2026

Orthodontic practices have a valuation dynamic that's unlike any other dental or medical specialty, and it comes down to one thing: the contract backlog. When a patient signs up for braces or Invisalign, they're committing to $5,000-7,000 in treatment fees paid over 18-24 months. A busy orthodontist with 600 active cases has $3-4M in committed future revenue sitting in their treatment pipeline. That backlog is an asset that doesn't exist in general dentistry or most other healthcare specialties.

Understanding how to value that backlog — and how it interacts with the broader practice economics — is what separates informed sellers from those who leave significant money on the table.

The Two Buyer Markets

Like general dental practices, orthodontic practices sell into two distinct markets with different valuation methodologies.

Private buyers— another orthodontist or a small group practice — value the practice on a percentage of collections. The standard range is 60-80% of trailing twelve-month collections for the practice goodwill, plus the net value of active contracts (remaining fees to collect minus remaining lab/supply costs). A solo ortho practice collecting $1.5M annually would sell for $900K-$1.2M in a private transaction.

DSO and PE-backed platforms value on EBITDA, and this is where orthodontic practices can command exceptional multiples. Platform acquisitions run 8-12x EBITDA. Bolt-on acquisitions for existing ortho-focused or multi-specialty DSOs trade at 6-8x EBITDA. A practice with $2M in collections and $600K EBITDA could sell for $3.6-7.2M to a DSO vs. $1.2-1.6M to a private buyer.

The DSO interest in orthodontics has intensified as platforms like Aspen Dental, Heartland Dental, and ortho-specific groups like Smile Doctors (backed by Linden Capital) and OrthoSynetics expand aggressively. These platforms recognize that orthodontics has higher margins than general dentistry (45-55% EBITDA margins vs. 25-35% for general) and more predictable revenue because of the contract model.

Valuing the Active Case Backlog

The active case backlog requires its own valuation analysis, separate from the ongoing practice value. Here's how it works.

Take each active case and calculate the remaining contract value (total case fee minus payments already collected). Then subtract the remaining cost to complete treatment (lab fees, supplies, appointment time). The net present value of those remaining payments, discounted for collection risk and time value, is the backlog value.

In practice, the math looks like this: 500 active cases with an average remaining balance of $3,200 each = $1.6M in gross remaining revenue. Subtract estimated completion costs of 15-20% ($240K-320K) and apply a 5-10% collection risk discount. Net backlog value: $1.15-1.28M. This gets added on top of the practice goodwill value.

The catch is that many buyers — especially DSOs — roll the backlog value into their EBITDA multiple rather than paying for it separately. This creates confusion during negotiations. If a DSO offers 8x EBITDA and their EBITDA calculation already includes the annualized backlog revenue contribution, the backlog isn't "free money on top" — it's already priced in. Make sure you understand how the buyer is treating the backlog in their valuation model before comparing offers.

Key Metrics That Drive Ortho Practice Value

New patient starts per month.This is the single most important operational metric in orthodontics. A healthy solo practice starts 20-35 new cases per month. Below 15, the practice is declining. Above 40, it's either a multi-doctor practice or a volume-driven model with concerning case acceptance rates. Buyers model new starts directly into their revenue forecast — a practice averaging 25 starts/month at a $5,500 average case fee is generating $137K in new contract value monthly.

Average case fee. This varies significantly by market and treatment mix. Traditional braces: $5,000-7,000. Invisalign: $4,000-6,000. Surgical orthodontics: $7,000-10,000. Practices with average case fees above $5,500 signal strong case acceptance and a willingness to present comprehensive treatment rather than discounting.

Production per chair per day. Efficient orthodontic practices generate $2,500-4,000 per chair per day. This metric captures both scheduling efficiency and case mix. Practices below $2,000/chair/day have utilization problems that buyers will need to solve post-acquisition.

Invisalign vs. traditional mix.The treatment mix matters because it signals different things to different buyers. A practice that's 60%+ Invisalign is attractive to DSOs because Invisalign cases require less chair time per visit, enabling higher patient throughput. However, traditional braces cases have higher per-case profitability ($2,500-3,500 margin vs. $1,800-2,800 for Invisalign after lab fees). The "right" mix depends on the buyer's operational model.

Conversion rate. What percentage of new patient consultations convert to started cases? Industry average is 65-75%. Practices above 80% have strong case presentation skills (or are in underserved markets). Below 60% suggests pricing, presentation, or competition issues. A 10-percentage-point improvement in conversion rate at 30 consults/month at $5,500/case adds $198K in annual new contract value.

The DTC Aligner Impact

SmileDirectClub's 2023 bankruptcy was widely seen as validation that direct-to-consumer aligners couldn't replace orthodontic care. And that's largely true — complex cases still require in-office treatment, and consumer trust shifted back to provider-supervised orthodontics. Invisalign remains the dominant clear aligner brand with roughly 80% market share.

But the DTC disruption did permanently change the market in two ways that affect practice valuation. First, it commoditized simple alignment cases — the $3,000-4,000 mild crowding case now faces price competition from Byte, Candid, and other survivors charging $2,000-2,500. Second, it raised consumer awareness of clear aligners, increasing overall demand but pushing more patients to ask about the cheapest option.

Practices that have adapted by focusing on complex cases (extraction cases, surgical orthodontics, TMJ-related treatment, and comprehensive adolescent orthodontics) are insulated from DTC pressure and command premium valuations. Practices heavily dependent on simple adult alignment cases face margin compression that buyers will price into their offer.

Multi-Location Economics

Orthodontists frequently operate 2-4 satellite offices, rotating between locations on different days. This creates a unique valuation consideration: multi-location practices command higher EBITDA multiples (7-10x vs. 5-7x for single-location) because they're harder to replicate and offer built-in geographic coverage that DSOs value.

However, the satellite model also means that production per location may look thin. A three-location practice collecting $2.5M total might only collect $800K at each location — which looks small on a per-location basis. Buyers evaluate the combined entity, but they'll stress-test whether each location is profitable standalone and whether the lease terms at each site support the practice's long-term viability.

The de novo vs. acquisition decision for growth is also relevant to valuation. DSO platforms generally prefer acquiring existing multi-location practices (instant scale, proven locations) over building new offices from scratch (12-18 month ramp to profitability, $300K-500K buildout cost per location). This preference translates to higher acquisition multiples for established multi-site groups.

The Bottom Line

Orthodontic practice valuation centers on the contract-based revenue model that makes this specialty unique. Active case backlogs represent committed future revenue worth $1-2M+ for a busy practice. Private sales trade at 60-80% of collections plus backlog value. DSO and PE platform sales trade at 6-12x EBITDA, with the highest multiples reserved for multi-location practices with strong new patient starts, balanced treatment mix, and provider depth beyond the selling orthodontist. The key to maximizing your exit: build the backlog, prove the new-patient pipeline, and demonstrate that the practice doesn't walk out the door when you do. DSOs are buying a system that produces orthodontic revenue, not a specific orthodontist's clinical skills.
