A patient who doesn't turn up isn't just a lost appointment: it's a chair, a nurse and a dentist paid for and not billing. And in a dental clinic it hurts more than elsewhere, because appointments are long and the calendar is booked weeks ahead — that hole was going to be filled by somebody who has now been told there's nothing until the following month.
The number nobody at the clinic has to hand
Before changing anything, get the figure. Count last month's missed appointments and multiply by what an average appointment bills. That number is what you're allowed to spend on fixing it — and it's usually far more than people expect.
What doesn't work: the reminder that only informs
«We remind you of your appointment on Thursday at 10:00» is a message that asks nothing. The patient reads it, feels informed, and if they can't come they still don't tell you — because nothing invited them to. The reminder that works asks for an answer: confirm, change or cancel. A cancellation the day before is a slot you can fill; a no-show at ten in the morning is not.
What does work, in order of impact
- A reminder that asks for a reply, 24 to 48 hours before, on WhatsApp and not by email. Confirmations get marked in the calendar, so the team knows what to expect from the day.
- Handling the reply in the same conversation: if they want to move it, move it there and then. Sending them to call the clinic loses half of them.
- A waiting list that fills what frees up — and in a clinic, whoever was waiting in pain goes first.
- A record of who misses: the same rule for everybody, applied from the second time, is fairer and easier to explain than deciding case by case.
The part that's usually forgotten: the first visit
The highest-risk appointment is the first one, from somebody who has never been to your clinic. They have no relationship with you, they found you on Google and they've probably written to three clinics. That appointment needs the confirmation the earliest, and it's the one where a reply worth reading matters most.
How to know it's working
Measure two things every month: what percentage of appointments were confirmed, and what percentage were missed. If confirmations go up and no-shows don't come down, the problem isn't the reminder — it's what happens after the patient replies. That's usually where it breaks.
