Worksheet · Updated 4 November 2026
What a missed call costs a dental practice, and the two-minute way to find your own number
A missed new-patient call costs a practice the first visit it would have booked, plus every visit after it. Put your own numbers in: missed calls a week, the share that were new patients, and what a new patient is worth to you in year one. For most practices the answer is one or two missed patients a week paying for a full-time front desk, several times over.
By the InRevHQ team, Bergen County, NJ. This is a worksheet, not a survey: we show the method and you supply the figures. No patient data is involved.
When practice phones go unanswered
Front desks are busiest at exactly the moments the phone rings most: 8 to 9 in the morning, the lunch hour, and the last hour of the day when the schedule for tomorrow is being confirmed. Add after 6 PM, weekends and the hygienist's lunch break, and a practice that is "always staffed" has a lot of hours where a ringing phone goes to voicemail.
A patient with a chipped tooth on a Friday evening does not leave a voicemail and wait until Monday. They call the next practice on the map. That is the cost we are trying to put a number on.
The worksheet
1. Missed calls per week. Pull the missed-call list from your phone system for the last full week. Count only calls that rang out or went to voicemail during hours you consider "open", then count the after-hours ones separately. Write both down.
2. Share that were new patients. Existing patients call back; new patients mostly don't. If you don't know, use one in three for daytime calls and one in two for after-hours calls, when people are more likely to be searching for anyone who will answer.
3. Value of a new patient in year one. Use your own average: first exam and cleaning, plus the treatment that typically follows in the first twelve months. Be conservative. Many practices land somewhere between the cost of a crown and a small implant case; use whatever your software says.
4. Multiply. Missed calls × new-patient share × year-one value × 52 weeks = what unanswered calls cost you a year.
A worked example (made-up numbers, so swap in yours)
| Line | Example | Your practice |
|---|---|---|
| Missed calls per week, during hours | 6 | |
| Missed calls per week, after hours | 4 | |
| New-patient share (⅓ daytime, ½ after hours) | 2 + 2 = 4 new patients a week | |
| Year-one value per new patient | $1,200 | |
| Lost per week | $4,800 | |
| Lost per year | about $250,000 |
Even if the example is three times too generous, a practice missing ten calls a week is leaving a front-desk salary on the table every year. And none of it shows up in a report, because the missed call was never a patient.
What "every call answered" sounds like for a practice
This is roughly what Maggie, our AI receptionist, says when a new patient calls a dental office after hours. The practice name is made up.
Maggie: Thanks for calling Bergen Family Dental, this is Maggie. How can I help you today?
Caller: Hi, I think I chipped a tooth. Are you open?
Maggie: Sorry to hear that. The office is closed right now, but I can get you in first thing. Is the tooth painful, or is it mostly the chip?
Caller: Mostly the chip. It's a little sharp.
Maggie: Got it. The first opening tomorrow is 8:10 AM with Dr. Patel. Can I have your first and last name to hold it?
Caller: Sure, it's Dana Reyes.
Maggie: Thank you, Dana. You're booked for 8:10 tomorrow. I'll text you the address and a link to the new-patient form. If the pain gets worse tonight, call this number back and I'll put you through to the on-call line.
What Maggie doesn't do matters as much: she doesn't quote fees, doesn't discuss insurance coverage beyond what the practice has told her, and never takes clinical detail. She books the time. For covered practices, the account runs on HIPAA-compliant infrastructure with a signed Business Associate Agreement.
Three ways to stop the leak, cheapest first
- Fix the after-hours greeting. Replace "leave a message" with "text us at this number and we'll reply within the hour", and actually reply. Free, and it catches some of the patients who would otherwise hang up.
- Put an answering service on overflow. Someone answers, takes a message, and the front desk calls back in the morning. Billed per minute at most services, and the call-back is still a step where patients drop out. We looked at what practices complain about.
- Put an AI receptionist on the line. Answers on the first ring, 24/7, books straight into the schedule, texts the confirmation, and writes every call down for the front desk to read in the morning. Our Grow plan is built for practices: $799 a month plus a $999 one-time setup. See how it works for practices.
Common questions
How many calls does a dental office miss?
It varies by practice and nobody's phone report tells the whole story, because voicemail hang-ups often aren't logged. The quickest honest answer is to pull your own missed-call list for one week and count. Most practices are surprised by the after-hours number.
What is a new dental patient worth?
Use your own practice-management software: average production per new patient in the first twelve months. It depends on your mix of hygiene, restorative and cosmetic work, so a worksheet with your figure beats any industry average.
Is an AI receptionist HIPAA compliant?
Ours runs on HIPAA-compliant infrastructure for covered practices, with a signed Business Associate Agreement, encrypted call recordings and access controls. Maggie books appointments and never takes clinical detail. We confirm the compliance scope in writing on the Strategy Call before anything is signed.
Will patients know it's an AI?
Yes. Maggie says so if asked, and a patient who wants a person can ask to be put through. Urgent calls ring the on-call line directly.
