When a practice starts thinking about an AI assistant, the same two questions always come up. And they're exactly the right ones: is it going to double-book my diary, and what happens when the patient needs to speak to a person?
They aren't fussiness: they're the two failures that ruin an assistant. The first sits two patients in the same chair; the second leaves somebody in pain talking to a machine that doesn't understand them, which is the fastest way to lose a patient. Let's take both, with what you should demand of anybody — us included — and the specific test you can run in a demo.
Failure 1 · The diary that double-books
The root of it is that a treatment isn't ONE duration. A root canal doesn't take the same on a molar as on an incisor, and a first visit with radiographs doesn't fill what a check-up does. If the assistant books with a single number per treatment, half the appointments run short and the other half waste the chair.
The expensive case is the quiet one: it doesn't look like a double booking, it looks like a diary that doesn't stretch and a dentist who runs late every day. The noisy one arrives afterwards, when two patients meet in the waiting room for the same slot.
What to demand of anybody: that the same treatment can have different durations and that the assistant ASKS which one before booking, instead of getting it right by luck; that the first visit carries its own margin; that each dentist has their own diary and their own treatments; and — the one nobody asks for — that somebody raises a flag if an appointment comes out shorter than that treatment needs. Getting it right isn't enough: it has to show the day it gets it wrong.
The demo test, and it takes two minutes: ask it to book a long treatment and show you exactly what it blocks in the diary, and with which dentist.
What you do have to set up
The real timings of your treatments, and which dentist does each one. Half an hour of work, once, and it's what separates a diary that stretches from one that double-books.
If a provider doesn't ask you for them when you sign up, that isn't them being easier to install: it's them booking blind. An assistant that doesn't know how long a root canal takes in your practice can't offer a time that's true.
Failure 2 · The conversation nobody picks up
The bot's bad name has a shape: the loop. The patient asks something the assistant doesn't know, the assistant answers something else, the patient rephrases it, and on until they give up. In a practice that's more serious than anywhere else, because whoever keeps trying is usually whoever is in pain.
What to demand of anybody: that when it doesn't know, it STEPS ASIDE — no insisting, no repeating the menu, no improvising; that the alert reaches somebody's phone with the name, the number and the reason exactly as the patient described it; that when a person steps in, the assistant GOES QUIET in that conversation; and that it doesn't come back on its own until the turn is handed back.
And one red line specific to the trade: an assistant doesn't assess symptoms or offer an opinion on how serious something is. It classifies, it prioritises and it alerts. Anything resembling clinical advice over the phone is a problem waiting to happen.
The demo test: ask it something it can't resolve and watch two things — whether the alert reaches a phone, and whether it goes quiet when a person replies.
And the third failure, that almost nobody asks about
What happens when it breaks. Because all software breaks; the difference is whether you find out.
An assistant that falls over quietly is worse than no assistant: you think you're covering the phone and you aren't. The call comes in, nobody takes it, and you discover it a week later through a patient who complains. Demand a log where you can see every call and every conversation with what actually happened, and alerts when something breaks.
We have it because we needed it ourselves first: the only way to fix quickly what breaks is to find out the same day.
In short
If you take one thing away, make it this: don't ask what an assistant can do. Ask what it does when it DOESN'T know, and what it blocks in your diary. Those two answers settle almost everything else.
And both can be checked in a five-minute demo, without taking anybody's word for it.
