Dental reactivation ROI methodology — how we calculate your $77k loss number
Every number in our ROI calculator, sourced and defended. If you're going to show your spouse or your CPA, use this.
The formula
Annual revenue loss from lapsed patients = Active patients × Lapse rate × Per-visit production × Visits per lapsed patient year. Every variable has a defensible source below. Plug in your own numbers and the math is the same.
Variable 1 — Active patients
This is your PMS's 'active patient' count: patients seen in the last 18 months. Every modern US PMS has this metric. Typical US practice distributions: solo 500–2,500, group 2,500–10,000, DSO 10,000–500,000+. If you don't know yours, run your PMS's standard patient-base report.
Variable 2 — Lapse rate (9% default)
The industry benchmark for lapse rate — defined as active patients who go inactive (> 18 months no visit) in a given year — is 8–12%. Source: ADA Health Policy Institute (annual dental practice survey), Levin Group benchmarking, and public case studies from RevenueWell, Weave, and Solutionreach, all of whom reference numbers in this range. We default to 9% as the midpoint. Your actual number varies: higher in high-churn geographies (urban multi-practice areas), lower in stable rural practices with multi-generational patient families.
Variable 3 — Per-visit production ($285 default)
The blended US average per-visit production across hygiene + restorative + diagnostic is ~$285 (ADA 2023 Survey of Dental Practice). Your number varies by specialty mix, geography, and insurance/fee-for-service mix. Pediatric practices tend lower; perio and prosthodontics higher; urban fee-for-service practices higher than rural PPO-heavy practices. Plug in your own from your PMS's production-per-visit report.
Variable 4 — Visits per lapsed patient (1.5× default)
A reactivated patient who returns typically completes one cleaning plus one restorative procedure inside 12 months. Some complete only the hygiene visit; some complete 2–3 follow-up treatments. 1.5× is a conservative midpoint. For specialty practices: ortho reactivations often span multiple visits (retainer checks, finishing adjustments); endo reactivations often end after the crown seat. Adjust per your specialty.
The math at three practice sizes
| Practice | Active | Lapsed/yr | Lost revenue/yr |
|---|---|---|---|
| Solo / small | 1,000 | 90 | $38,475 |
| Solo / avg | 2,000 | 180 | $76,950 |
| Group / avg | 5,000 | 450 | $192,375 |
| Large group | 10,000 | 900 | $384,750 |
| DSO | 50,000 | 4,500 | $1,923,750 |
This is the raw loss. Reactivation tools recover a portion of this, not all of it.
What a reactivation tool actually recovers
At the self-run end (1–3% reactivation of lapsed), the recovered fraction of the loss is ~10%–30%. At the dedicated-tool end (8–15% reactivation), the recovered fraction is ~45%–80%. So for the 2,000-patient practice, recovered revenue is $8,000 (self-run worst case) to $60,000 (dedicated-tool best case). A realistic midpoint on a dedicated tool is ~$30k/yr. Tool cost at Practice Pro ($697/mo × 12 = $8,364/yr). Net: ~$20k–$25k/yr.
How we'll update this over time
As our own client base grows, we'll publish our observed reactivation rates by segment, channel, practice size, and specialty in a quarterly transparency report (starting Q4 2026). Until then, the industry benchmarks above are the best public data. Trust hub →
