Lapsed dental patients: how to bring them back properly

Lapsed dental patients are people on your records who have stopped attending: they missed their recall, never rebooked, and have not been seen for well beyond the interval their dentist set. They are a natural group to approach, because they already know where you are and you already hold their history. But it has to be done carefully, because a message to someone you have not seen for three years can count as marketing in law. This guide covers how to define and segment your lapsed list, the ICO and PECR rules, what to say, and how to make coming back easy.

What is a lapsed dental patient?

There is no official definition, so each practice sets its own. A sensible one starts from the recall interval. NICE guideline CG19 recommends intervals between check-ups of 3 to 24 months for adults and 3 to 12 months for under-18s, set for each patient based on risk. So:

• Overdue: past their recall date, but by less than one full interval. Usually just busy, and your normal recall follow-up should handle them.
• Lapsed: past their recall date by more than one full interval, or not seen for more than 24 months whatever their interval, since NICE treats 24 months as the longest routine interval for adults.
• Unfinished treatment: a treatment plan accepted or discussed but never completed. These deserve their own list and a clinical conversation, not a marketing message.

What does it mean to recall a patient?

Recalling a patient means inviting them back for their next routine check-up when the interval set by their dentist falls due. Reactivation is what happens when recall has not worked. Recall is routine and scheduled. Reactivation is a deliberate effort to reach people who have dropped out of the routine, which is why it needs its own list, its own messages and its own owner.

Can an NHS dentist remove you from their list?

NHS dentistry in England does not work like a GP list. The NHS tells patients that filling out a form to register at a first visit "does not mean you'll always be able to get NHS dental care at the same dental practice in the future". In other words, there is no permanent list to be removed from, and a patient who has not attended for years cannot assume an NHS appointment will be available.

For a mixed or NHS practice this shapes the message. Do not imply that lapsed patients have a guaranteed NHS place waiting. Say plainly what you can offer now: NHS appointments if you have capacity, private appointments if you do not, or a waiting list. Patients who arrive expecting one thing and are offered another rarely stay.

Build and clean the lapsed list first

Before sending anything, pull the list from your practice management software and clean it. Sending messages to people who have died, moved abroad or asked not to be contacted causes distress and complaints.

Also note how each patient's contact details were collected and what they agreed to. That decides what you are allowed to send, which is the next section.

The rules: is a reactivation message marketing?

Often, yes. The ICO says messages that confirm or remind people about appointments are service messages and not marketing. But a message that "actively promotes or encourages people to make use of a particular service, special offer, or upgrade" is likely to be direct marketing, and the ICO says phrasing, tone and context decide which side a message falls on.

A neutral note to a patient who is a few months overdue sits close to a recall reminder. A campaign to people not seen for three years, especially one with an offer, is much closer to marketing. If in doubt, treat reactivation as marketing and follow the marketing rules:

• Texts and emails need either consent or the soft opt-in. The ICO says the soft opt-in only applies where you collected the details while selling or negotiating to sell, you are marketing similar services, and you gave the person a simple way to opt out when you collected their details and in every message since. If you are not sure those conditions were met for a patient, ask for consent instead.
• Every marketing message must include an easy way to opt out, such as replying STOP or an unsubscribe link, and you must act on it.
• Marketing phone calls must not go to numbers registered with the Telephone Preference Service unless the person has specifically consented to your calls, and the ICO says this applies even if they are an existing customer.

The stakes went up in 2025. The ICO says the Data (Use and Access) Act 2025 brings PECR enforcement into line with UK GDPR, so penalties are now the same in most cases.

What to say to lapsed patients

The best reactivation messages are short, warm and practical. They do not guilt the patient, and they do not make clinical claims about what might be happening in their mouth.

• Say who you are and that it has been a while.
• Make it easy: a direct booking link or phone number, and your opening hours.
• Answer the likely worry: cost, NHS availability, or nerves about coming back after a long gap.
• Give the opt-out.

A text along these lines works for patients who have agreed to hear from you:

PRACTICE: Hi NAME, it has been a while since we last saw you. If you would like to book a check-up, call 01234 567890 or book here: LINK. Reply STOP to opt out.

An email can carry more: what a return visit involves, your current prices, NHS availability, and a line for nervous patients saying they can ask for a longer first appointment. Keep clinical detail out, because the ICO says appointment details and reminders can count as health data when they reveal something about a person's health.

Avoid offers that pressure people, such as "book this week or lose your place". Patients who come back because they were rushed are less likely to stay.

A simple reactivation sequence

1. First message by the channel the patient agreed to, usually text or email.
2. Second message two to three weeks later if there is no response, by a different channel where allowed.
3. A letter for patients with no valid mobile or email, or who have not responded to either.
4. A phone call for priority segments, such as unfinished treatment, only within the TPS rules above.
5. Stop. Patients who do not respond to the sequence should be marked and left alone until their details are next checked. Repeated chasing does more harm than good.

Make coming back easy

A lapsed patient who decides to return will usually look you up first, often on Google. Check that what they find matches your message: current opening hours on your Google profile, a website that says whether you are taking NHS or private patients, visible prices and a booking route that works on a phone. If your message says "book online" and your booking page has nothing for six weeks, the effort is wasted.

Some patients stay away because they are anxious, or worried about what a long gap will mean. Train the front desk to treat the returning patient's first call as a welcome, not an interrogation about why they have been away.

How to measure reactivation

Track each segment separately, because they behave differently. For each send, record how many messages were delivered, how many patients booked, how many attended, and how many then booked their next recall. The last figure matters most: a patient who returns once and lapses again has not really been reactivated. Compare your results with your own previous campaigns rather than with figures quoted elsewhere, because patient lists, locations and NHS or private mixes vary too much for outside benchmarks to mean much.

Preventing the next lapsed list

Reactivation fixes the past. A recall system with clear intervals, timely reminders and a weekly check of the overdue list prevents patients from lapsing in the first place. And because some patients will always move away, the practice also needs a steady flow of new ones.
