Every dental practice misses calls. The phone rings while the receptionist is checking in a patient, taking a payment or already on another line, and the caller hangs up. Most practices never measure how often that happens, so they never see what it costs.
This guide shows you how to put a dollar figure on missed calls at your own practice, using your own numbers rather than someone else's averages, and what you can do about it.
Key takeaways
- A missed call isn't free. Some callers ring back, but a share of new-patient callers simply call the next practice on Google.
- You can estimate the cost with four numbers: missed calls per week, the share that were new patients, your booking rate, and the value of a new patient.
- Most missed calls cluster at predictable times: opening, lunch, and late afternoon. That makes them fixable.
- The fix doesn't have to be another hire. Call overflow, after-hours cover and an AI receptionist can all pick up calls your team can't.
Why missed calls matter more in dentistry
Dental patients often ring when they have a problem, such as a toothache, a chipped tooth or a lost filling. Those callers want an appointment now, and if nobody answers they keep going down the search results. New patients are also usually shopping around. If your practice doesn't pick up, the practice down the road might.
Existing patients are more forgiving. They'll often leave a voicemail or call back. But even then, a missed call creates extra work: someone has to listen to voicemail, call back, play phone tag and eventually book the appointment that could have been booked on the first call.
Step 1: Find out how many calls you actually miss
Before you calculate anything, get real numbers. Most phone systems and VoIP providers can report:
- Total inbound calls per day and per hour
- Answered vs unanswered calls
- Abandoned calls, where the caller hung up while waiting or ringing
- Calls that went to voicemail, and how many voicemails were left
Pull at least two to four weeks of data so one unusual week doesn't skew the picture. Look at the pattern by hour, not just the total. If you can't get reports from your phone system, ask the front desk to keep a simple tally for a week. It won't be perfect, but it's better than guessing.
Step 2: Work out the value of a new patient
Use your practice management software to estimate what an average new patient is worth to the practice over a sensible period, such as the first 12 months. Include the first exam and clean, any restorative work that typically follows, and the recall visits they usually book.
Be conservative. If you're unsure, use your average first-year revenue per new patient rather than lifetime value. The goal is a number you'd be comfortable defending to your accountant.
Step 3: Run the calculation
Here's a simple formula you can put in a spreadsheet:
Monthly cost of missed calls = missed calls per month × share that are new patients × share who would have booked × share who don't call back × value of a new patient
A worked example, using made-up figures that you should replace with your own:
- Missed calls per month: 120
- Share from new patients: 30%
- Share who would have booked if answered: 60%
- Share who never call back: 50%
- First-year value of a new patient: $800
That works out to 120 × 0.3 × 0.6 × 0.5 × $800 = $8,640 a month in new-patient revenue at risk, before you count existing patients who don't rebook or the staff time spent on callbacks.
Your figures will differ. The point is to replace guesswork with a number you can track and improve.
Step 4: Count the hidden costs too
Lost bookings are only part of the cost. Missed calls also lead to:
- Callback time. Every voicemail needs listening to and returning, often more than once.
- Front desk pressure. Staff who feel the phone ringing while they're with a patient are rushed and stressed, and patients at the desk notice.
- Gaps in the book. A patient who wanted to fill tomorrow's cancellation but couldn't get through leaves that chair empty.
- Reputation. Callers who can't get through sometimes say so in reviews.
When are calls being missed?
In most practices, missed calls cluster around a few predictable windows:
- Opening time, when overnight voicemails, emergencies and the first patients all arrive at once
- Lunch, when the desk is short-staffed or closed
- Late afternoon, when patients ring after school or work
- After hours and weekends, when nobody is there at all

How to reduce missed calls
1. Fix the basics first
Make sure your phone system rolls over to a second line or handset when the first is busy, that voicemail tells callers when they'll hear back, and that someone owns voicemail first thing each morning.
2. Protect phone time at peak hours
If you can, roster one person to focus on the phones during your busiest windows instead of combining phones with check-in and payments.
3. Add overflow cover
Overflow cover answers the calls your team can't. That can be a human answering service or an AI receptionist that picks up when the desk doesn't, handles routine bookings and passes everything else to your team.
4. Make booking possible without a call
Online booking and a website chat that can take booking requests reduce the number of routine calls in the first place. See our comparison of online booking options.
Where an AI receptionist fits
An AI receptionist answers every call, including overlapping calls and calls after hours. It can check availability, book routine appointments into your calendar, answer common questions about hours, location and parking, and hand off anything clinical or urgent to your team according to rules you set.
It isn't a replacement for a good front desk. It catches the calls your team can't take, so they can focus on the patients in front of them. If you want the full picture, read how AI receptionists work, what they cost and where they stop.
Frequently asked questions
What's a normal missed-call rate for a dental practice?
There isn't a reliable public benchmark for Australian dental practices, and rates vary widely with staffing and call volume. The useful benchmark is your own practice over time. Measure it now, make a change, and measure again.
Do callers leave voicemails?
Some do, but many new-patient callers don't, especially if they're ringing several practices. Don't assume a missed call will show up as a voicemail.
Should I call back every missed number?
Yes, if you can do it quickly. A prompt callback recovers some bookings. But callbacks cost staff time, and patients who have already booked elsewhere won't come back, so answering the first time is always better.
Is it worth paying for after-hours cover?
Run the calculation above using only your after-hours missed calls. If the monthly figure is higher than the cost of cover, it probably is.
