Missed calls and what they cost a dental practice
Dental practice missed calls are inbound calls nobody answered: they rang out, hit voicemail or were abandoned in a queue. Each one is an enquiry you may have paid to generate and then lost at the first step. You don't need an industry average to know what they cost you. Your own call log and appointment book can tell you, and this page shows how.
It covers counting missed calls properly, valuing them with your own figures, and reducing them. It is one stage of the wider picture of why enquiries don't book.
Counting missed calls
Your phone system almost certainly reports inbound, answered and unanswered calls. The raw count overstates the problem in some ways and understates it in others, so clean it before you use it.
| Adjustment | Why |
|---|---|
| Count unique callers, not calls | One patient ringing three times is one missed enquiry, not three |
| Remove callers who got through later the same day | They were delayed, not lost |
| Split opening hours from out of hours | Different causes, different fixes |
| Separate existing patients from new | Match numbers against the practice management system (PMS); existing patients usually ring back |
| Include voicemails not returned | A voicemail with no callback is still a missed enquiry |
Call tracking, which records each call's source, time and duration, adds one more useful field: which marketing produced the call. Google Ads, for example, counts calls from ads and calls to tracked numbers on your website as conversions when they last at least a minimum length you set1, so a missed call from a paid ad is spend with nothing to show for it. How to set tracking up without disturbing your listings is covered in call tracking for practices.
Check what the phone system may not show. Calls that dropped while waiting in a menu or queue, calls to a second line or a mobile, and calls to an old number still printed somewhere can all be missing from the headline report. Ask your phone provider which of these it counts before you trust the total.
Then map the missed calls by hour and day. Peak hours, the periods when most calls arrive, rarely match the periods when reception is free.
Putting a value on them
The value of missed calls is an estimate of what was at risk, built only from your own figures. The method multiplies four numbers:
| Input | Where it comes from |
|---|---|
| Missed new-patient calls not recovered in a month | Your cleaned call log |
| Booking rate for answered new-patient calls | Answered calls that became a booked consultation, from the practice system |
| Start rate from booking to treatment | Booked consultations that became treatment |
| Average contribution per treatment start | Revenue minus variable costs such as lab fees, by treatment line |
Illustrative figures, not benchmarks: the example below uses invented round numbers.
| Illustrative figures, not benchmarks | Value |
|---|---|
| Missed new-patient calls not recovered | 20 |
| Booking rate for answered new-patient calls | 40% |
| Start rate from booking | 50% |
| Average contribution per start | £400 |
| Value at risk per month | 20 × 0.4 × 0.5 × £400 = £1,600 |
Two cautions. Missed callers are not identical to answered ones; some would never have booked, and some tried again elsewhere. And the result is value at risk, not money lost for certain. Use it to decide whether fixing call handling is worth more than the next increase in ad spend. Your own numbers will say which.
Split the calculation by treatment line if you can. A missed implant enquiry and a missed hygiene enquiry are not worth the same.
Reducing them
Missed calls usually come from a mismatch between when calls arrive and when someone is free to answer. The fixes are operational, and they belong to the practice.
| Fix | Owner | What it does |
|---|---|---|
| Rota reception to the heatmap, not to habit | Practice manager | Staff are free when calls peak |
| Move non-urgent tasks, such as payments and admin calls, out of peak hours | Practice manager | Frees the phone at the busiest time |
| Call back every missed new number within an agreed time | Reception | Turns a missed call into a delayed one |
| Overflow calls to a second phone or colleague | Practice manager | Fewer calls ring out |
| Voicemail that gives the callback time and the online booking link | Reception | The patient knows what happens next |
| Online booking for consultations | Practice, with marketing | Patients who hate waiting can book themselves |
| Report missed calls monthly, by source | Marketing | The problem stays visible |
The callback is the most important line. A missed call returned quickly is often just a slightly slower enquiry. Response time for calls, forms and messages is the subject of speed to lead.
Marketing can track, count and report missed calls, and send fewer wasted ones by targeting better. Answering the phone and calling back are the practice's job. If you would like your missed calls counted and valued from your own log, email me at Fayez@imfayez.com. The first look costs nothing: I check the numbers and call routes your site, ads and profile show from the outside, and reply with what I find. Working from your call log is part of an engagement, set out in how I work.
