D-01 — PATIENT ACQUISITION COST · DENTAL GROUPS & DSOs

Cost per new patient is climbing — dental groups

Rising cost per new patient — and no industry number to compare it to

DIFFERENTIAL — LIKELY CAUSES, MOST LIKELY FIRST

1. 01

   The comparison itself is the error — there is no benchmark to be high against

   The owner is managing to a number that has no chain of custody, so "rising" and "high" are being judged against nothing.

   ADA HPI's Table 13 reports practice expenses for owner general practitioners as a single aggregate — average $556,450, median $509,720, first quartile $322,820, third quartile $747,130, n = 367 — and never breaks out advertising, marketing or patient-acquisition spend as a line item. The US Census 2022 Economic Census publishes operating expenses for NAICS 621210 in aggregate only; purchased-advertising-services detail is not published for the sector. Every "spend 4–7% of revenue" or "2–5% of collections" figure found traces to a vendor blog with no stated sample, and is usually prescriptive rather than observed.

   ADA Health Policy Institute, 2026 Survey of Dental Practice, Table 13; US Census Bureau, 2022 Economic Census, EC2200SIZEREVEST (NAICS 621210)

   NOT THIS IF — The figure being compared against is the practice's own instrumented history — its own spend over its own counted new patients. That number is real. It is simply not comparable to anyone else's.

2. 02

   The denominator is wrong — "new patients" is not being counted the way the industry counts it

   Spend is divided by calls, form fills or first-time appointments rather than by new patients per location per month, so the ratio moves with the tracking configuration rather than with the market.

   The two largest practice-management datasets disagree by about 15% on this exact unit for the same period — Henry Schein One reports an industry average of 39 new patients per location per month, Planet DDS reports 46 new patients per practice per month (up from 43 in 2024, n ≈ 5,200 Denticon practices disclosed). Same metric name, two populations, two denominators. If the industry's own publishers land 15% apart, an internal number computed against an undefined denominator carries no information at all.

   Henry Schein One, 2026 Catalyst Index; Planet DDS, 2026 Dental Industry Outlook

   NOT THIS IF — Marketing spend and practice-management-system new patients already reconcile, by location, by month, and the series can be re-run for any prior month without reconstruction.

3. 03

   Conversion fell, not media price — access is the constraint

   The same spend produces the same inbound demand, but a smaller share of it becomes a booked, shown new patient, so the whole cost lands on fewer patients.

   Appointment lead time averages 23 days against roughly 7 days for top performers (Henry Schein One). ADA HPI independently confirms the direction from a Tier A instrument: the average wait for an initial appointment for a new patient at a general practice went from 6.7 days in 2018 and 7.9 days in 2019 to 16.0 days in 2025. It roughly doubled.

   Henry Schein One, 2026 Catalyst Index; ADA Health Policy Institute, 2026 Survey of Dental Practice, Table 22 (series 1990–2025)

   NOT THIS IF — First available new-patient appointment is inside about a week at every location and the phone is answered live during business hours.

4. 04

   Retention loss is forcing the practice to re-buy the same panel

   Patients leaving the active base at a faster rate means acquisition spend is replacing rather than adding, so cost per net new patient rises while cost per gross new patient looks unchanged.

   Industry patient retention fell to 64% from 72% year over year. Segmented: solo practices average 70%, 8+ location groups average 58%. Hygiene reappointment within 12 months is 63%, meaning roughly four in ten hygiene patients leave without a next appointment booked.

   Henry Schein One, 2026 Catalyst Index (press release and retention blog); Planet DDS, 2026 Deep Dive for hygiene reappointment

   NOT THIS IF — The 18-month active-patient base is growing at roughly the same rate new patients arrive — then acquisition is genuinely additive.

5. 05

   Payer mix — the patients cost the same and are worth less

   Cost per new patient is being read against a falling collected value per patient, so the ratio deteriorates without the cost side moving at all.

   For owner general practitioners, 50.0% of gross billings come from private insurance carriers (DHMO/DPPO), 40.2% from direct patient payment, 7.3% from government programs and 2.5% other. Dental Economics / Levin Group reports that only 10% of practices are fully fee-for-service, average insurance coverage per practice is 57%, and 50.5% of respondents had one or more plans lower reimbursement in 2025.

   ADA Health Policy Institute, 2026 Survey of Dental Practice, Table 11; Dental Economics / Levin Group 19th Annual Practice Survey (2025 data)

   NOT THIS IF — Fee schedules and plan participation are unchanged year over year and collections per new patient in the first 12 months are flat or rising.

HOW TO TELL THEM APART

How to tell these apart in your own numbers

Each of these is a measurement you can run yourself, without us.

WHAT RESOLVES EACH

What resolves this, and how you will know it resolved

The comparison itself is the error — there is no benchmark to be high against	Rx 04 · marketing attribution →	The deliverable is an instrumented internal baseline with a written definition, not a benchmark. ADMEN will not supply an industry cost per new patient for general dentistry, because none exists with a chain of custody — that position is stated publicly on /sources/ and /benchmarks/ and it does not change inside a sales conversation.
The denominator is wrong — "new patients" is not being counted the way the industry counts it	Rx 04 · marketing attribution →	New patients per location per month, from the practice management system, reconciled to spend by location by month. Until the two series share a denominator, every cost-per-new-patient number produced is an artifact of the tracking.
Conversion fell, not media price — access is the constraint	Rx 03 · patient conversion →	Call-center instrumentation, online booking and routing, same-day capacity matching. Raising the budget is the wrong lever here and makes the ratio worse. Henry Schein One's own words: "Top-performing groups don't necessarily spend more on marketing. They make it easier for demand to convert."
Retention loss is forcing the practice to re-buy the same panel	Rx 03 · patient conversion →	Recall and reappointment measured at the chair. A practice replacing 8 points of retention every year is running acquisition to stand still, and the cheapest correction — book the next visit before the patient leaves — costs nothing.
Payer mix — the patients cost the same and are worth less	Rx 04 · marketing attribution →	Reporting can isolate the effect and size it. It cannot fix it. This is a contracting and fee-schedule problem, and the answer is renegotiation or plan exit — which is not marketing work and we would say so before quoting anything.

HOW THIS DIFFERS BY SCALE

How this differs by scale

Single site	Spend is small enough that one noisy month swings the ratio, so measure trailing 12 months and never month over month. Keep the wallet in proportion: a solo owner general practitioner's entire practice expense base excluding shareholder salary has a median of $509,720 (ADA HPI Table 13), and marketing is a small slice of that — the room to overspend is smaller than a vendor proposal usually assumes.
Group	The denominator failure is close to universal at 2–25 locations: spend contracted centrally, patients counted locally, and no reconciliation between them. Fix that before touching the media plan. Report per location — a group average conceals a site at 12 new patients a month sitting next to one at 70.
Platform	In the board pack the term becomes CAC; on the operating floor underneath, it is still cost per new patient, and group-scale dental operators have to get both vocabularies correct on the same page. Reconcile it to collections rather than production before it is presented — Henry Schein One shows 8+ location groups collecting 72% on average against 97% for the top 10%, so production-based unit economics overstate the platform by a wide margin.

OTHER PRESENTATIONS — DSO & GENERAL DENTISTRY

• Plateaued growth — production flat while the marketing invoice holds or climbs
• Thin pipeline — the phone rings and the chair stays empty
• Multi-site variance — one brand, one playbook, and a fourfold spread between locations
• Preparing for exit — making growth read as a system rather than as a good year
