Ask an orthodontic practice owner what their new-patient conversion rate is, and most will say somewhere between 80% and 90%. Ask Gaidge Analytics — which aggregates data from thousands of orthodontic practices — and the answer is closer to 64–68%. Planet DDS's 2025 data puts it at 64.4%.
That gap between what owners believe and what the benchmarks show is one of the most consistent findings in orthodontic practice management research. It persists because most practices don't track conversion rigorously — they track consults scheduled and starts, but not the full funnel from initial inquiry to booked consultation.
How conversion is actually measured
True new-patient conversion in orthodontics has three stages, and most practices only measure the last one:
Stage 1: Inquiry to scheduled consultation. A prospective patient calls or contacts the practice. Do they get a scheduled consultation, or do they fall off? This is where a significant portion of inquiries are lost — missed calls, voicemail callbacks that don't connect, or a consultation scheduled too far out for the patient to stay engaged.
Stage 2: Scheduled consultation to attended consultation. How many booked consultations actually show up? No-show rates in orthodontic consultations run 15–25% at practices without strong reminder systems.
Stage 3: Consultation to treatment start. The presentation conversion — how many patients who attend a consultation decide to start treatment.
The 64–68% benchmark from Gaidge Analytics captures the full funnel — inquiry to start. Most practices tracking only stages 2 and 3 see numbers that look much better, which is why the self-reported estimates run 15–20 points higher than the actual benchmark.
Where the gap comes from: Stage 1
The most recoverable part of the conversion gap sits at Stage 1. Prospective orthodontic patients — often parents calling on behalf of a child, or adults researching Invisalign in the evening — are comparison-shopping. Research suggests up to 5 practices may be contacted before a patient chooses one. The practice that answers the call and books the consultation wins the inquiry. The practice that sends it to voicemail often loses it.
Evening and weekend calls are disproportionately high for orthodontic practices because parents and adult patients call when they have time — which is rarely during the practice's peak clinical hours. A practice that only answers calls 8 AM–5 PM Monday through Friday is structurally missing the highest-intent window for new-patient inquiries.
What one additional start per month is worth
Average orthodontic case value in the U.S. is approximately $5,500 (Gaidge Analytics, 2022). At 12 additional starts per year — one per month — that's $66,000 in incremental revenue, gross, before direct costs.
This is the math that makes after-hours call coverage worthwhile for orthodontic practices specifically. If a practice is missing 3–4 consultation calls per month because they come in after 5 PM, recovering 2 of those is a $11,000/month revenue improvement — and the AI receptionist that converts those calls costs a fraction of that.
How to benchmark your own practice
Track these four numbers for 90 days: total new-patient inquiries (calls + forms + texts), consultations scheduled, consultations attended, and treatment starts. Divide starts by total inquiries for your true conversion rate. Most practices running this exercise for the first time find a number 10–20 points lower than they expected.
If your Stage 1 funnel (inquiry to scheduled consultation) is the weak point — which it is for most practices — the fix is ensuring every inquiry gets an immediate response and a frictionless path to a booked appointment. That means answering every call, including the ones that come in when your team is with patients or when the office is closed.
The practices outperforming the 64–68% Gaidge benchmark are almost universally better at Stage 1: they answer more inquiry calls, they respond faster, and they book the consultation before the patient calls the next practice on their list.
