Dental Recall System: Kill the Six-Month Postcard

A dental recall system is the quietest revenue engine in your practice. It's also the one most offices set up once and never check again. If yours is a reminder every six months and a shrug, it's leaking.

Here's the contrarian part. The Canadian Dental Association doesn't back a one-size-fits-all six-month rule. It says recall timing should come from a risk assessment of each patient, set by the dentist with the patient.

So your software's default interval isn't a clinical decision. Below is how to build a recall system for a Canadian practice: intervals, reminders across channels, waitlist backfill, what to measure and the privacy basics. It's the setup we'd build for any office in Ottawa.

Set Intervals by Risk, Not by Habit

The CDA lists what should drive recall timing: cavity risk, gum health, cancer screening, growth and development, and the patient's medical status. That's a clinical call. Your system's job is to store it and act on it.

In practice, each patient carries their own interval in your software. The CDA says higher-risk patients should come in more often and lower-risk patients less often. The dentist sets it, the system enforces it.

Here's my bet: the interval isn't your biggest leak. It's the patient who walks out without the next visit booked. Pre-book at checkout every time, so your reminders protect a date instead of chasing one.

The Dental Recall System Reminder Sequence

One reminder is not a system. People miss texts, ignore email and let calls go to voicemail. You need a sequence that switches channels and stops the moment they book.

A simple version looks like this:

1. At checkout: Book the next recall visit before they leave.
2. When they're due and not booked: Send a text with a booking link or a "reply YES" option.
3. A few days later: Send an email with the same link, for patients who live in their inbox.
4. Still nothing: A phone call from your team, or from an AI receptionist for your dental office that can book on the spot.
5. Once booked: Confirmation and reminders before the visit. Our guide to AI appointment reminders covers that part.

Now the CASL piece. Under section 6(6) of CASL, a message that only confirms or completes a deal the patient already agreed to doesn't need consent. A "you're due, book now" message is likely closer to a sales message, and implied consent from a past purchase generally runs two years under section 10.

So patients you haven't seen in over two years need express consent before you text them. Put your office name and an easy opt-out on every message, and see our CASL text templates for the format. This isn't legal advice, so run your wording past your lawyer.

Waitlist Backfill: Fill Cancellations Fast

Cancellations will happen. The question is whether the chair sits empty. A waitlist turns a cancelled hygiene slot into a booked one, if you move fast.

Here's the setup:

• Ask patients with future bookings if they want an earlier spot. Save their yes and their preferred times.
• When a slot opens, text everyone on the list who fits the time. First to reply gets it.
• Tell everyone else it's filled and that they're still on the list.
• The patient who moved up just freed their old slot, so offer that one too.

This is tedious for a person and easy for software. It's the same logic behind AI rescheduling: the faster the offer goes out, the better your odds of filling the chair.

What to Measure, and the Privacy Basics

Most offices count reminders sent. That number tells you nothing. Measure what shows the system is working:

• Overdue patients: active patients past their recall date with nothing booked.
• Pre-book rate: the share of recall visits that end with the next one booked.
• Booking rate by channel: which of text, email or phone actually gets people booked.
• Cancellation fill rate: how many freed-up slots the waitlist fills, and how fast.

Now privacy. In Ontario, PHIPA treats regulated health professionals, dentists included, as health information custodians, and the IPC's handbook for small health care organizations says you stay accountable even when a vendor runs the software. Outside the provinces with their own laws, PIPEDA's ten fair information principles, like limiting use and safeguards, set the baseline across Canada.

The practical rule: keep reminders boring. Your office name, a date and a link. Leave treatment details out of texts and email, since you can't control who sees a patient's phone.
