Missed call cost for a dental clinic equals new-patient calls per week, times the share missed, times the share who would book, times your show rate, times the first-year value of a new patient. Enter your own numbers below. The defaults are placeholders, not averages.

Revenue at risk per month
Per year: CAD
- Missed new-patient calls per month
- Lost exam bookings per month
- Lost new patients per month
Revenue at risk per month = calls per week × % missed × 4.33 weeks × % who would book × show rate × first-year value
20.0 calls/week × 25% missed × 4.33 weeks = 21.7 missed calls/month. × 50% would book = 10.8 exams. × 85% show = 9.2 new patients. × $1,500 first-year value = $13,813/month. × 12 = $165,750/year.
Counts are rounded for display. The math uses unrounded values.

How do you calculate missed call cost for a dental clinic?
The calculator runs five steps of plain arithmetic on your inputs:
- Missed calls per month = new-patient calls per week × % missed × 4.33 (52 weeks ÷ 12 months).
- Lost exam bookings = missed calls × % who would have booked.
- Lost new patients = lost bookings × your show rate.
- Revenue at risk per month = lost new patients × first-year value of a new patient.
- Revenue at risk per year = the monthly figure × 12.
| Input | Where to find it | Common mistake |
|---|---|---|
| New-patient calls per week | Phone system or VoIP call log, new numbers only | Counting recall and confirmation calls |
| % missed | Unanswered plus voicemail, divided by all new-patient calls | Leaving out hang-ups before voicemail |
| % who would book | Your booking rate on answered new-patient calls | Not lowering it for callers who ring again |
| Show rate | Scheduling report: new-patient exams attended over booked | Using the rate for all appointment types |
| First-year value | New-patient production report, last 12 months | Using lifetime value, which inflates the result |
Checked November 2026. The example numbers on this page (20 calls a week, 25% missed, 50% booking, 85% show rate, $1,500 first-year value) are placeholders to show how the tool works. They are not averages for Canadian clinics.
What counts as a missed call in a dental office?
A missed call is any new-patient inquiry that no person answered live. Dental offices lose them in predictable spots, so check these windows in your call log first:
- Checkout and chairside: the front desk is booking a patient out while the phone rings.
- Lunch hour and the morning rush: everyone is either away or already on a call.
- Before opening and after close: people search for a dentist in the evening, then call.
- Weekends: a toothache on Saturday goes to voicemail.
Count voicemails as missed. Some callers will still book after you return the call, so reflect that by lowering the "would have booked" percentage instead of leaving voicemails out.
What is a new dental patient worth in the first year?
Your own reports answer this better than any benchmark. Pull production for patients whose first visit fell in the last 12 months, then divide by the number of those patients. That figure already includes the exam, x-rays, hygiene visits and any treatment they accepted.
Use first-year value, not lifetime value. A lifetime figure makes the leak look bigger but is much harder to defend, and it hides how many patients leave after one visit. If you cannot split the data, enter a lower number than you think and see whether the fix still pays.
If the result looks too high, lower the booking rate first. If it looks too low, check whether your log counts hang-ups that never reach voicemail. Those are missed inquiries too.
What should a dental clinic fix first?
Run the calculator twice: once with after-hours calls only, once with busy-hour misses only. The larger result tells you where to start.
1. Cover the busy hours and after hours
An answering service or an AI receptionist can pick up when the front desk cannot, collect the caller's name and number, and book a new-patient exam into your schedule. Compare options in our guide to a dental office AI receptionist in Canada and the page on a dental answering service in Canada.
2. Send a missed-call text
When a call still slips through, a short text within a minute or two tells the caller you saw it and offers a booking link. Keep it to logistics. Never discuss symptoms or treatment by text. Start from our missed-call text back templates, and have your lawyer check the wording against CASL.
3. Protect the patients you already have
Recall is the other half of the schedule. A clinic that answers every new-patient call but lets overdue patients drift still has a leak. See our guide to dental recall software and systems, or the AI employees for dental clinics overview.
Dental missed call cost calculator: FAQ
How much do missed calls cost a dental clinic?
It depends on your own numbers. Multiply missed new-patient calls by the share who would have booked, your show rate and what a new patient is worth in the first year. With this page's example inputs the result is about $13,813 a month, but those inputs are placeholders, not averages.
Which calls count as missed in a dental office?
Count any new-patient inquiry call that no person answered live, including calls sent to voicemail and hang-ups during checkout, lunch or the morning rush. Leave out existing patients confirming visits, labs and vendors.
What is a new dental patient worth in the first year?
Use your own practice management reports. Add up the production from patients whose first visit fell in the last 12 months and divide by the number of those patients. Include the exam, x-rays, hygiene and the treatment they accepted.
Should I count dental emergency calls separately?
Yes, if you can. Emergency callers and routine new-patient callers may book at different rates and be worth different amounts, so run the calculator once for each group and compare.
Can an AI receptionist or text back fix missed dental calls?
It can answer after hours, book new-patient exams and send a missed-call text. It should not discuss diagnoses or give clinical advice, your dentist stays responsible for clinical decisions, and your clinic stays responsible for patient privacy. General information, not legal advice.
