Start with the figures you have been quoted #
Two numbers dominate the marketing in this space. One says that 35 per cent of calls to dental practices go unanswered. The other says that up to 42 per cent of your business could be lost through missed calls.
We went looking for the studies behind both on 19 September 2026 and found supplier pages with no named sample, no described method and no date. They are not findings, they are claims, and repeating them would make this page worse rather than more persuasive.
The nearest thing to a usable UK figure is not about clinics at all. Moneypenny published a small business call report on 27 January 2020, based on 300 micro businesses plus call data from 10,000 businesses.

A four person practice is a micro business by any definition, so the finding is suggestive. It is still not a finding about clinics, and the second half of it is the more interesting half: most people who fail to reach you leave no trace at all, so your own sense of the problem is built from the minority who did.
Why the clinic version of this is harder than the trade version #
A plumber misses a call because they are under a sink. A clinic misses a call because the only person who could answer it is in front of a patient, and the cost of interrupting that is not just rudeness. So the phone is answered between patients, in the gaps, by somebody who is also taking payments, greeting arrivals and finding a file.
The consequence is documented, if only anecdotally. A dental practice manager told Dentistry.co.uk on 20 September 2021 that the courtesy calls her practice used to make before appointments had stopped because things were so busy, and that cancellations had gone up.
That is the real bill: reception capacity is a single pot, and inbound noise drains the pot that outbound work was supposed to come from. The same mechanism is why the waiting list never gets worked.
Sorting the calls honestly #
| What the call is | What it needs | Can it be taken off reception? |
|---|---|---|
| Opening hours, address, parking, what to bring | A published fact | Yes |
| Confirming or cancelling an appointment | Identity, then a diary change | Partly, and the identity step is the whole risk |
| Asking to be called back | An accurate message and a route | Yes |
| Asking about a bill or a claim | Account detail, sometimes a decision | Partly. Routing yes, answering usually not |
| Describing a symptom | Clinical judgement about urgency | No |
| In pain, distressed, or with a sick animal in the car | A person, immediately | No, and this is not a close call |
The top of that table is a genuine slice of the volume. It is also the easiest slice, which is exactly why it is worth removing: it is the slice currently standing between the hard calls and a human being.
Where these systems actually go wrong #
Diagnosis, not prescription, so here is the failure list rather than a build:
- They take a message and nobody is accountable for what happens to it next.
- They confirm identity badly, and discuss an appointment with the wrong person.
- They are too confident, answering a clinical question they should have handed over.
- They give no obvious way to reach a person, so the caller hangs up and rings a competitor.
- They are never listened back to, so nobody learns what people actually ring about.
- They handle the daytime overflow and leave the evening, which was the real gap.
The fifth one is the quiet waste. A month of call reasons, grouped, is the single most useful piece of management information a clinic reception can produce, and almost nobody produces it. It usually shows that a large share of the volume is three questions the website could have answered.
The data protection line #
A call about an appointment confirms that the caller is your patient, which is information about their health and therefore special category data under UK GDPR. That makes the identity check on an inbound call a data protection control rather than a courtesy.
It also makes a recorded or transcribed call a store of special category data that somebody has to be responsible for. Your practice stays the controller whichever supplier answers the phone. The patient data page points at the ICO's guidance rather than interpreting it here.
What to look at first #
Your phone system already knows the answer to the only question that matters. Mobile networks and VoIP providers produce call records showing unanswered inbound calls with a timestamp, and a month of that data tells you your own missed call rate, by hour and by day.
Then spend a week writing down what people rang about. Those two exercises cost nothing and beat every published percentage in this sector, including the honest one. The missed calls tool turns your own count into hours and money without asking you for anything.
