The average dental practice retains only 57% of patients over an 18-month period. That means 43% of patients who visited you in the last year and a half haven't come back. These aren't strangers — they're people who already know your practice, have been through your door, and have a treatment history with you.
Reactivating a lapsed patient costs a fraction of acquiring a new one. Studies consistently show that acquiring a new patient costs 5-25x more than retaining an existing one. Yet most practices spend their entire marketing budget on new patient acquisition and nothing on reactivation.
When I ran my practice, our lapsed patient list was enormous and untouched. Nobody was systematically reaching out. When we finally did, the response rate surprised us — many patients simply needed a prompt.
Why Do Patients Lapse?
Life got busy. The most common reason. They didn't actively leave your practice — they just forgot to rebook.
No recall system prompted them. If your practice doesn't systematically contact patients who are overdue, you're relying on the patient to remember. Most won't.
A bad experience. Sometimes it's a long wait, a billing surprise, or a personality clash with a team member. These patients can be recovered if approached correctly.
They moved. Some lapsed patients are genuinely gone. Don't waste resources on these — focus on the recoverable ones.
What Does a Reactivation Campaign Look Like?
Segment your list by time lapsed:
Message sequence (per segment):
Message 1 (WhatsApp or SMS): Friendly, personal, no hard sell. "Hi [name], it's been a while since your last visit at [practice name]. We'd love to see you — here's a link to book a check-up at a time that works for you."
Message 2 (1 week later, if no response): Add a reason to act. "Just a reminder — regular check-ups help catch small issues before they become big (and expensive) ones."
Message 3 (2 weeks later, if no response): Final prompt. "We don't want to keep bothering you, but we genuinely care about your dental health. If you'd like to stay with us, book anytime here: [link]. If not, no hard feelings at all."
Expected response rates: 15-25% for 6-12 month lapsed patients, 8-15% for 12-24 month, 3-8% for 24+ month.
The Revenue Impact
If you have 500 lapsed patients (6-24 months overdue) and recover 15% through a reactivation campaign, that's 75 returning patients. At an average treatment value of £300-£500 for a returning check-up and hygiene appointment, that's £22,500-£37,500 from a campaign that costs essentially nothing beyond the messaging platform fee.
And these patients don't just come back once. They re-enter your recall cycle, generating recurring revenue for years.
