Every dental practice has a long list of patients who used to come in and quietly stopped. They didn't complain or ask for their records. Life got busy, a recall reminder was missed, and 18 months later they're no longer on anyone's radar. Those patients already know your practice, and many of them are overdue for care.
Reactivation is the process of bringing them back. This guide covers how to find lapsed patients, what to say, which channels to use and how to keep it respectful.
Key takeaways
- Lapsed patients are often your easiest source of "new" bookings, because they already know you.
- Segment them by how long they've been away and what they had planned.
- Acknowledge the gap without guilt. Make coming back feel easy and welcome.
- Use a short sequence across SMS, email and phone, then stop.
- Respect opt-outs and keep the content within privacy and Spam Act rules.
Why patients lapse
Understanding why patients stop coming helps you write the right message. Common reasons include:
- They missed a recall reminder and never rebooked
- Cost worries, or uncertainty about their health fund cover
- Dental anxiety, sometimes made worse the longer they stay away
- Moving house or changing jobs
- A treatment plan that felt overwhelming
- A poor experience they never mentioned
Most of these are about inertia, not dissatisfaction. A friendly, easy invitation solves many of them.
Step 1: Find your lapsed patients
Run a report in your practice management software for patients who:
- Have no future appointment booked, and
- Haven't been seen in the last 18 months (adjust this to suit your practice)
Then remove anyone who has:
- Asked not to be contacted
- Transferred their records to another practice
- Died (check this carefully; contacting the family of a deceased patient is very distressing)
Step 2: Segment the list
Different groups need different messages:
- 18–24 months: a straightforward "you're overdue" message usually works.
- 2–3 years: acknowledge it's been a while and make coming back feel easy.
- 3+ years: treat them almost like new patients, with a welcoming first-visit message.
- Unfinished treatment: a careful, personal message from the practice about following up, ideally reviewed by the dentist.
- Children and teens: message the parent or guardian, and mention the Child Dental Benefits Schedule if they may be eligible.
Step 3: Write messages that work
Good reactivation messages:
- Come from the practice by name
- Use the patient's first name
- Acknowledge the gap without blame
- Give one clear action
- Are short
Example SMS for an 18–24 month group:
"Hi Sam, it's Harbourside Dental. It's been a while since your last check-up, and we'd love to see you again. Book online here: [link], or reply YES and we'll call you."
Example for a 3+ year group:
"Hi Sam, it's been a few years since we've seen you at Harbourside Dental. If you'd like a fresh start, we'll take it at your pace. Reply YES and we'll find a time that suits."
Avoid guilt ("You haven't been in for three years!") and scare tactics about dental health.
Step 4: Use a short multi-channel sequence
A sensible sequence over four to six weeks:
- SMS with a booking link or reply option
- Email a week later, with a little more about the practice, any new team members and how to book
- Phone call a couple of weeks later for patients who haven't responded, if they've agreed to calls
- Stop. Mark non-responders and try again in six to twelve months
Stop the sequence as soon as a patient books or asks you to stop.
Step 5: Make it easy to say yes
The reactivation message is only half the job. The other half is making it easy to book:
- Phone lines answered quickly, including at lunch and after hours
- Online booking that shows real availability
- Reply-to-book that results in a fast callback or confirmation
- Clear information about costs and health funds for patients worried about price
Keep it compliant
Reactivation messages sit closer to marketing than routine reminders, so check two things:
- Spam Act: commercial messages need consent, must identify the sender and need a working unsubscribe. See our Spam Act guide for dental SMS.
- Privacy: use patient information only in ways patients would reasonably expect, and keep records of opt-outs. If automated systems help decide who is contacted, see the December 2026 privacy change on automated decisions.
Where automation helps
Reactivation is a classic job that never gets done when the front desk is busy. Automation can segment the list, send personalised messages on schedule, make outbound calls, book patients who say yes and stop when they respond. IntelliDent's recall agent sends personalised SMS and email outreach to bring overdue patients back.
Frequently asked questions
How far back should we go?
Many practices start with patients last seen 18 months to 3 years ago. Older records may have outdated contact details and are more likely to bounce.
Should we offer a discount to bring patients back?
That's a business decision, but be careful. Offers make the message commercial under the Spam Act, and Ahpra's advertising rules restrict how practices advertise prices and offers.
What if a patient replies angrily?
Apologise, thank them for telling you, offer to remove them from messages and pass any complaint to the practice manager.
