If you run growth or marketing at a multi-location dental group, you already know the conversation that’s happening right now: chair capacity keeps going up, the funnel doesn’t. The number that should be obvious — what a new patient actually costs in 2026 — is still the one most teams quote from memory or from a vendor pitch deck.
So here’s the math from primary sources, with the channels broken out and the scale-specific cliffs that show up at 100, 500, and 1,000 locations called out separately. No “$185 went to $312” trajectory invented for a slide. Actual numbers, with the citations live so anyone on your team can pull them.
The single most useful number: $290–$420 nominal, $240–$340 effective
Patient Prism’s 2026 benchmark report puts the median multi-location dental group patient acquisition cost between $290 and $420 nominal — meaning per inquiry generated — and $240 to $340 effective once you adjust for the 63–72% conversion rate they observe across well-run group practices.
Two things matter about that range.
First, it’s wider than a CPL-only number suggests. The reason is that conversion-rate variance between groups is bigger than channel-cost variance. A DSO doing 72% inquiry-to-booked-appointment conversion gets the same effective CAC at a $420 nominal as a DSO at 63% gets at $340 nominal. Improving the front desk is doing more than switching channels in many cases.
Second, the cross-specialty average — pediatric, ortho, GP combined — is $370–$375. If your number is materially higher, the question to ask is whether your specialty mix is dragging the math (cosmetic and implant-led DSOs run higher), or whether your channel mix has aggregated too heavily into the expensive end.
Channel mix — where the math actually decomposes
Dentplicity’s 2026 channel benchmarks give us the cleanest comparison currently published. The full table:
| Channel | Cost per acquisition |
|---|---|
| Google PPC | $150–$350 |
| SEO / organic | $50–$150 |
| Referrals | $25–$75 |
| Direct mail | $300–$600 |
A few patterns worth flagging. The PPC range is wide because of bidding compression. In top-25 MSAs with three to five DSOs bidding the same “[city] dentist” terms, the high end of $350 is now the floor in some markets. Wisdom-teeth removal and Invisalign queries in metros like Los Angeles, Miami, and Dallas now clear $50+ CPC. If your DSO operates in those metros and PPC is your largest channel, the $290 nominal floor isn’t realistic — you’re probably running at $380+ before the funnel does any work.
SEO at $50–$150 is a 3-6 month lagging investment. It’s the lowest-CAC channel, but it doesn’t backfill a Treatment Coordinator who started Monday. That gap — capacity coming online faster than organic compounds — is where most growth-marketing CMOs end up paying for some other source.
Referrals at $25–$75 are the holy grail, and the cap is biological — your existing patient base can only refer at a fixed rate. Heartland’s 2024 numbers help illustrate this: with 2,800+ doctors and an industry-typical 25–30% of new patients coming through referral, the absolute referral throughput at network scale is large, but it doesn’t grow linearly with new-location openings.
Direct mail at $300–$600 is the outlier most teams under-attribute. It rarely closes the loop because most DSOs don’t run mailable-only landing pages. If you’re running mail at scale and your CAC math doesn’t include it, your number is artificially low.
The scale cliff that hits at 100, 500, and 1,000 locations
This is the part that’s not in any one published source — it shows up only when you compare DSO press releases to channel-cost trajectories. At three different scale points, the math breaks differently.
At ~100 locations: the local-PPC floor
Below 100 locations, you can typically run lean PPC in your operating markets and live within the $290–$370 nominal range. The bidding competition is local and your spend doesn’t move the market price.
At ~500 locations: the brand-channel inflection
Once you’re at 500+ locations across multiple states, your existing patient base is large enough that brand search becomes a real channel. Smile Doctors at 550+ locations across 36 states (4 added in March 2025 via the myOrthos acquisition, +70 locations net) crosses this line. Branded queries start at $50–$80 CAC versus $200+ for non-branded. The cliff is that your channel mix shifts toward brand defense — keeping competitors from buying your name — which is cheap when it works and expensive when it doesn’t.
At 1,000+ locations: paid acquisition becomes 25–35% of the mix, not 50%+
Heartland Dental at 1,800+ supported practices, 2,800+ doctors, and 105 new practices added in 2024 (89 de novo + 16 relocations across 39 states + DC) is in a category where direct paid acquisition is no longer the dominant channel — the patient base + referral throughput + brand-search defense covers most of the funnel. But each de novo opening sits in a market with zero existing patient base. De novo locations typically take 6–18 months to reach mature production, and the patient-acquisition load during that window is the part of the math that most DSO CFOs underestimate at acquisition-planning time.
PDS Health at $3.1B revenue, 77 new practices added in 2025, and 1,000+ practices crossed in 2024 hits a similar pattern. Aspen Dental at ~1,100 offices and 21 new in 2025, with 5.2M patient visits, runs a higher paid-channel share than Heartland because Aspen’s brand-as-acquisition-channel works at scale due to consumer TV.
The takeaway: at every scale point, the question is not “what is my CAC” but “what is the right channel-mix shape for my current scale, and what gap does it leave.”
The consolidation rate behind these numbers
For context on why this matters now versus three years ago: Dykema’s 2025 M&A sector spotlight puts DSO-affiliated practices at 25% of all U.S. dental practices, with 120+ add-ons in 2024 — the highest of any healthcare services category — across 120+ U.S. DSOs.
What that means operationally: every existing DSO is competing for acquisition targets with more buyers than ever, and every acquired location lands into a more competitive paid-acquisition market than it would have three years ago. The math gets harder, not easier, as the category consolidates.
Where exclusive-lead sources fit
This is the question we get asked most. The short version is that exclusive-lead sources (a single inquiry routed to a single buyer, never shared) sit in a different math bucket than the channels above.
A shared-lead aggregator delivers an inquiry that may have been routed to 3–7 other practices. The conversion-rate impact is well-documented in the Henry Schein case-acceptance research — speed to first contact drives conversion, and shared leads structurally lose that race for whoever isn’t the fastest.
An exclusive-lead source delivers an inquiry to one practice with no race. The CAC is typically higher per inquiry than aggregator pricing, but the effective CAC after conversion adjustment is often lower because the conversion rate isn’t fighting for first-contact position.
For multi-location groups at 100+ locations with central marketing infrastructure, exclusive-lead programs are usually the channel that sits between the paid-search floor and the referral throughput ceiling — filling the gap that opens when chair capacity outruns brand pull. The decision isn’t whether to use them; it’s how much of the channel mix to allocate, and which markets.
What to do with this
If you’re inside a DSO marketing team right now, three useful pulls from the data:
1. Compare your effective CAC (CAC ÷ conversion rate) to the $240–$340 Patient Prism range — not your nominal CPL. Most teams quote the nominal and the variance there is largely a conversion-rate gap they’re not fixing.
2. Know which side of the scale cliffs you’re on. At 100 locations the channel mix that worked at 30 doesn’t compound. At 500 you should be defending brand and not relying on it. At 1,000+ the de novo math is the part your CFO will catch eventually.
3. If your channel mix is more than 50% paid (PPC + paid social + direct mail) and you’re growing through acquisition, the inflection point — where adding more spend to existing channels stops compounding — is closer than the spreadsheet suggests. The earlier you find a complementary exclusive-lead channel, the cheaper the gap costs to close.
I write about this stuff because we sit at the intersection — PeakIntent runs exclusive-lead programs for multi-location dental groups, and the questions we get from CMOs almost always come down to the channel-mix question above.
