    How to Bring Back Overdue Dental Recall Patients

    General information, not legal advice. This guide explains a process in plain language so you know what to ask. Amplified Marketing is not a law firm, reading this guide does not create a lawyer-client relationship, and nothing here guarantees that any campaign complies with the law. Health privacy, texting and dental advertising rules change often. They differ by state and province, and they depend on what a message says and what each patient agreed to. Consult a licensed lawyer who knows health privacy and texting law, and check your dental regulator's rules, before you message patients. Rules are current as of the date above.

    Bringing back overdue recall patients: the short answer

    Pull every patient who is past their recall date with nothing booked, sort them by how long they've been overdue, send each group a plain message from your office, and have someone answer every reply the same day and book it.

    The patients most overdue are the hardest to bring back, so start with the most recent ones.

    Why overdue patients slip

    Most overdue patients didn't leave. They just didn't book. The recall card got lost, they changed jobs, or nobody followed up after the first reminder.

    How often someone should come back is a call for the dentist, not a marketing rule. In the UK, NICE guidance says the interval should be set for each patient, from 3 months up to 24 months for adults and up to 12 months for patients under 18 (NICE). Use the interval your dentist set for each patient when you decide who is overdue.

    Step 1: Pull the list

    Run a report in your practice management software for patients who:

    • Are past their recall date
    • Have no future appointment booked
    • Are still active patients (not moved away, not transferred, not deceased)

    Keep the last visit date, the recall due date, phone, email and whether they agreed to texts or emails.

    Step 2: Sort by months overdue

    Different groups need different messages. For example:

    • Overdue up to 18 months. They still think of you as their dentist. A simple "you're due" message usually fits.
    • 18 to 36 months. Something got in the way. Ask, and make booking easy.
    • More than 3 years. Many have moved or found another dentist. Expect fewer replies, and check contact info first. One marketing agency's published write-up reported that 15% to 25% of contact records are outdated for patients inactive longer than two years.

    Step 3: Check consent and privacy before you send

    Patient contact details and visit dates are health information, so more rules apply than for a plumber's customer list. Here's the general picture. Your lawyer should confirm how it applies to your practice.

    US: health privacy (HIPAA)

    • Reminders are usually part of treatment. HHS says appointment reminders are part of a patient's treatment and can be sent without the patient's written authorization (HHS). HIPAA's definition of marketing also leaves out communications made for a patient's treatment and communications about the provider's own health services (45 CFR 164.501; HHS). A message that only tells a patient they're due for care at your office generally fits these exceptions.
    • When it becomes marketing. If another company pays you to send the message, for example to promote its product, those exceptions generally no longer apply, and you need each patient's written authorization first (45 CFR 164.501; 45 CFR 164.508(a)(3)).
    • Outside companies need a written agreement. If an outside company sends messages or answers replies for you, it is usually your "business associate." You need a signed business associate agreement before it gets patient information (45 CFR 164.502(e) and 164.504(e); HHS).
    • Keep messages short on details. HHS suggests limiting what you put in messages others might see, like a voicemail (HHS). "You're due for a visit" shares less than naming a treatment.
    • State laws. Many states have their own health privacy laws on top of HIPAA.

    US: texting rules (TCPA)

    • Marketing texts sent with an autodialer generally need prior express written consent (47 CFR 64.1200(a)(2)). The same rule makes an exception for health care messages sent by or for a HIPAA-covered provider, which don't need written consent.
    • The FCC also lets health care providers send certain texts to cell phones without prior consent, but only if every condition is met (47 CFR 64.1200(a)(9)(iv)). The text goes only to the number the patient gave you, costs the patient nothing and doesn't count against their plan, names your practice and how to reach you, and is limited to purposes like appointment reminders and wellness checkups. It has no marketing, billing or payment content, is 160 characters or less, and offers a reply STOP opt-out that you honor right away. You can send no more than one per day and three per week to each patient.
    • Add an offer and you likely lose the health care path. Whether a "you're overdue" text to someone who hasn't visited in years counts as a health care message isn't settled, so ask your lawyer.
    • Opt-out, quiet hours and state rules still apply. See our US texting laws guide.

    Canada: health privacy

    • Ontario. Dentists are health information custodians under the Personal Health Information Protection Act (PHIPA s.3). Using patient information to market anything, or for market research, needs the patient's express consent (PHIPA s.33). If an outside company works with your patient information for you, it acts as your agent, you stay responsible for the information, and the company may use it only as you permit (PHIPA s.17). Companies that provide electronic services to you have their own duties (PHIPA s.10(4); O. Reg. 329/04, s.6). Put the arrangement in writing.
    • Other provinces. Each province has its own rules. For example, Alberta's Health Information Act covers dentists (OIPC Alberta). In British Columbia, the Personal Information Protection Act generally covers private practices (BC PIPA). Quebec has its own privacy laws, updated by Law 25, and a separate health information law may apply to some providers (Quebec). In some provinces, the federal PIPEDA applies (Office of the Privacy Commissioner). Check which law covers your practice.

    Canada: texting and email (CASL)

    • CASL has no health care exemption. A text or email counts as a commercial electronic message if one of its purposes is to encourage someone to buy something, like a paid visit (CRTC). A recall message asking a patient to book will often count, and one with an offer will. Plan as if your recall texts and emails need consent.
    • A reminder about an appointment the patient already booked can be exempt from the consent rule, but only if it does nothing else. It still needs your identification and an unsubscribe option (CASL s.6(6)(b)). An overdue patient with nothing booked usually doesn't fit that exemption.
    • Implied consent from a purchase lasts 2 years (CASL s.10(10)). Count from the patient's last paid visit, not their recall date. For a patient whose last paid visit was more than 2 years ago, you'll generally need express consent on file before you text or email them. That may include many patients in the longer-overdue groups in Step 2.
    • Phone calls follow separate telemarketing rules. See our CASL guide.

    Your dental regulator

    Dental regulators have advertising rules, and they vary. For example, Ontario's dental regulator says not to use incentive programs like giveaways or free products or services, not to use testimonials, and not to share fees with a third party based on the business an advertising campaign brings in (RCDSO). Ontario's rules also make it professional misconduct to contact potential patients in person or by phone to solicit them, or to have anyone do it for you (O. Reg. 853/93, s.2, para 47). In the US, rules vary by state. For example, Florida requires a specific statement in any ad for a free or discounted exam or service (Fla. Stat. 456.062). Check your regulator's rules before you put any offer in a message.

    Ask your lawyer which of your messages count as care reminders and which count as marketing, before you send.

    Step 4: Send plain messages that sound like your office

    Keep it short, use the patient's first name, say who you are, and give a way to stop messages. For example:

    Hi Maria, it's [Practice Name]. Our records show you're due for a checkup. Want us to find a time? Reply STOP to opt out.

    For patients overdue a long time:

    Hi James, it's [Practice Name]. It's been a while since your last visit and we wanted to check in. If you'd like to come back in, reply here and we'll find a time. Reply STOP to opt out.

    Keep offers out of recall messages unless your lawyer and your regulator's rules say they're fine. In Canada, a commercial text also needs your contact information, which can be a link to a page with your mailing address and a phone number, email or website (Electronic Commerce Protection Regulations (CRTC), ss.2 and 3). If you rely on the US health care texting exception, keep each text to 160 characters or less, like the first example.

    Use more than one channel if you have consent for it, and keep phone calls to your own patients of record. One marketing agency's published write-up reported that a single postcard or single email usually gets 1% to 3%, while a sequence across text, email, phone and mail typically books 8% to 15% of contacted patients within 60 days. Results vary by practice and list.

    Step 5: Answer every reply the same day and book it

    This is where most recall campaigns leak. The patient replies "yes" while your front desk is checking someone in, and nobody gets back to them until next week.

    Give replies to one person whose job is to answer and book. That's why we put a dedicated SDR on every reply. If an outside team answers replies for you, it will see patient information, so put the written agreement from Step 3 in place first.

    For reference, one marketing agency's published case write-up reported that a UK practice texted 800 lapsed contacts, and 61 booked. Results vary by practice and list.

    Step 6: Track kept appointments, not sends

    Track four numbers for each group: messages sent, replies, booked and kept. Then, if your regulator's rules allow it, ask patients who come back for a review. Some regulators, like Ontario's, don't allow testimonials in advertising, so don't repost reviews in your ads or on your site. When you reply to a review, never confirm that the person is a patient or share any details of their care.

    What makes the difference

    Most agencies automate the follow-up, or hand it back to your front desk. A text goes out and a link gets sent, but often nobody answers when the patient writes back. We put a dedicated SDR on every reply, so a patient who answers gets a response the same day and a time that works.

    How this fits into your growth plan

    Bringing back overdue patients is one piece of a bigger plan. Dental practices have their own advertising and fee rules, so we confirm the scope and how we're paid in writing, and your lawyer should review it before anything starts.

    Before any reactivation campaign, we go through your list and consent records with you and confirm the scope in writing. We are not your lawyers, and your lawyer should sign off on the plan.

    FAQ

    How do I find overdue recall patients with nothing booked?

    Run a report in your practice management software for active patients who are past their recall date and have no future appointment. Keep the last visit date, recall due date, contact info and consent.

    How often should patients come back for a checkup?

    Your dentist sets it for each patient. In the UK, NICE guidance puts it between 3 and 24 months for adults and up to 12 months for patients under 18 (NICE).

    What should a recall reactivation text say?

    Keep it short: the patient's first name, your practice name, that they're due, an easy way to book, and a way to opt out.

    Do I need consent to text overdue patients?

    Often, yes, in some form. It depends on where you practice, what the message says and what the patient agreed to. In the US, HIPAA generally treats a reminder about care at your own office as treatment, but texting rules still apply, and an offer can change the answer (HHS; 47 CFR 64.1200). In Canada, a recall text asking a patient to book will often be a commercial message under CASL, so you need implied consent, such as a paid visit in the last 2 years, or express consent (CASL s.10(10)). Read our US and Canada guides and check with your lawyer.

    How many overdue patients come back?

    There's no neutral benchmark. One marketing agency's published case write-up reported that a UK practice texted 800 lapsed contacts and 61 booked. Results depend on how overdue they are, your contact info and how fast replies get answered.
