Two-thirds of American adults saw a dentist last year. The CDC's early release of 2025 National Health Interview Survey data puts the share of adults with a dental exam or cleaning in the past year at 66.7%, and its 2022 brief on adults 65 and older found 63.7% had a visit: 69.6% with dental coverage, 56.4% without. The other third includes patients in your own software whose last cleaning was eighteen months ago, who liked you fine, and never booked the next one. They are the cheapest appointments you will ever fill, because they already chose you once.
Why the recall list matters more this year
A hygiene hour is scarcer than it was. In the ADA Health Policy Institute's April 2026 analysis, only 60% of dentists said they had enough hygienists on staff, and among those recruiting, 91% called it very or extremely challenging. Becker's Dental Review, reporting the Institute's third-quarter 2026 survey, said about a third of dentists were recruiting hygienists and 21.2% of the positions had been open for more than six months. An empty slot in a column that hard to staff costs more than it used to.
Who is overdue: three piles from your own software
Your practice-management software already keeps the list. In Open Dental, for example, every active patient sits on the Recall List under a recall type (Prophy, Perio or Child Prophy), the due date is calculated from the last completed recall procedure plus the interval, and the manual suggests a prophy interval of "6 months plus 1 day so that six month recalls are not accidentally scheduled too early." Dentrix, Eaglesoft and the rest have an equivalent report; find yours, then sort it into three piles:
- Due: past the due date by up to three months. Nobody is avoiding you; nobody asked.
- Overdue: three to 24 months past due. Something got in the way: a lost insurance plan, a bad experience nobody heard about, or a reminder sequence that ran out.
- Inactive: the ADA's definition is a patient of record who "has not received any dental service(s) by the dentist in the past twenty-four (24) months." The ADA says to have "a functional and documented process for moving patients from active to inactive status on a regular basis," with the records kept for as long as state law requires.
Six months is a habit, not a rule: a 2020 Cochrane review of two trials with 1,736 participants found "little to no difference between six-monthly and risk-based check-ups in tooth decay, gum disease and quality of life after four years" in adults, so the interval in the chart is the dentist's call and the script should respect it rather than announce "it's been six months." A periodontal maintenance patient on a three-month interval is overdue sooner and matters more; put the Perio list on top.
How many times, in what order
The trial evidence is about appointment reminders rather than recall, but it points the same way. A Cochrane review of eight trials found attendance of 67.8% with no reminder, 78.6% with a text and 80.3% with a phone call; a 2016 BMJ Open review of 26 studies found multiple notifications raised attendance by 25%, against 6% for one; and a 2011 study at a university pediatric dental clinic found a voice message produced a no-show rate of 8.2% against 17.7% for a text. So: text first, send more than one, and put a human voice in the sequence. No study we found sets the right number of recall attempts, so test this starting point against your own report:
- At the due date: a text with a booking link.
- Two to three weeks later: a second text with two specific open times.
- About six weeks past due: a phone call; if nobody answers, a voicemail that says nothing is wrong and gives the number and the link.
- From three months past due: one message a quarter, alternating text and call, until the patient books, asks you to stop, or reaches 24 months.
- At 24 months: one last call or letter, then inactive status under your written procedure.
Set the sequence in the software, not in someone's memory. Open Dental's recall setup has fields for the days between reminders and a "Max # of Reminders" before a patient drops off the list; your system has the same dials. A patient who never comes off the list gets the same text for three years, which is how a practice collects opt-outs instead of appointments.
Three rules every recall message follows
Consent. The FCC's 2015 ruling treats the number a patient gives a healthcare provider as prior express consent, and exempts care messages from further consent when they are free, carry the provider's name and number, contain no advertising or billing, run to no more than one a day and three a week, and honor a STOP reply. "You're due for a visit" is a care message. "$50 off whitening when you rebook" is marketing, for which the wireless carriers' code expects written agreement; keep offers out. Our text-template guide covers the carrier registration that decides whether the message arrives.
Content. HHS says a reminder should carry the practice name and number and "other information necessary to confirm an appointment," and that providers should limit what goes in an unencrypted message. "Your next visit" is fine; "your periodontal maintenance" tells anyone who sees the phone what the patient has.
Stopping. Since April 2025 the FCC requires senders to honor an opt-out made by any reasonable method, including replies such as "stop," "cancel" or "unsubscribe," within ten business days at most, with one confirmation text and nothing after it. Note it in the chart; the automated sequence ends.
The scripts
Each text is under 160 characters with the practice name first and a number a person answers. Each call opens with the hygienist's or dentist's name, never with the word "overdue."
Text 1, at the due date
"[Practice]: it's time for your next cleaning and check-up with [hygienist]. Book here: [link], or call [number]. Reply STOP to opt out."
Text 2, two to three weeks later
"[Practice]: we have Tue 8:10am or Thu 4:30pm open for your cleaning. Reply 1 or 2 to take one, or call [number]. Reply STOP to opt out."
The phone call, about six weeks past due
"Hi [name], it's [your name] at [practice]. [Hygienist] asked me to check in: your next cleaning was due in [month] and I'd like to get you back on her schedule. I have Tuesday at 8:10 or Thursday at 4:30; would either work?"
If the answer is a reason, the reason is the call:
"I lost my insurance." "That happens to a lot of our patients. A cleaning and exam is $[fee], and our membership plan is $[amount] a month for both visits a year. Shall I book the cleaning and have the details ready when you come in?"
"I've been going somewhere else." "Understood, and thank you for telling me. Would you like us to send your records and x-rays over? I'll make a note so we stop reminding you."
The first answer leans on a membership plan if you have one and on our insurance scripts if you don't. The second ends the sequence and keeps the goodwill.
The reactivation call, a year or more past due
"Hi [name], it's [your name] at [practice]. It's been a while since we saw you, and Dr. [name] asked me to reach out before we update our records. If you'd like to come back, I can book a cleaning and exam this week; and if anything about your last visit put you off, I'd rather hear it than guess."
The last clause does more than any offer: a patient who left over a wait, a bill or an unreturned call will tell you, and the reply is the one you would give under a review, delivered privately.
The half of recall you cannot script
Every recall text produces calls, and they arrive when the text is read: at 12:30, at 6:40 pm, on Saturday morning. If the call reaches voicemail, the text has moved the patient from "forgot" to "tried and gave up," which is worse. Pull the call log for the day after each recall batch and count the calls that rang out; our lunch-gap guide shows how. Whatever answers then, a service or an AI receptionist, should know the hygiene slot lengths, quote the cleaning fee and membership plan from the lists you approve, book, and tell the desk. ClinicEcho does that and sends a transcript within a minute, for $497 a month with a 14-day free trial, under a BAA signed first. Run the after-hours call test on the number in your own recall text at 7 pm.
Five numbers a month
Patients who came due, contacted, booked, arrived, and moved to inactive. Due but not contacted is a software setting; contacted but not booked is a script or phone problem; booked but not arrived belongs to the no-show policy. In the cost per booked patient report, the recall row is usually the cheapest.

Frequently asked questions
How often should a dental practice contact a patient who is overdue for a cleaning?
Start with a text at the due date, a second text two to three weeks later and a phone call at about six weeks, then one message a quarter until the patient books, asks you to stop, or reaches 24 months without a visit. The review evidence says more than one reminder works better than one; it does not say how many is too many, so set a maximum in your software and test it against your own recall report.
Is a recall reminder a marketing text under the TCPA?
A reminder that a patient is due for care, sent to the number the patient gave you, with the practice name and number and no offer in it, fits the FCC's healthcare exemption. The moment it says "$50 off whitening when you rebook" it is marketing, which needs separate written consent. Keep offers out of recall messages and send them, if at all, from a separate list.
When does an overdue patient become an inactive one?
The ADA's definition is a patient of record who has had no dental service from the dentist in the past 24 months. Before that date they are overdue and still yours to call. After it, move them to inactive status under a written procedure, keep the records for as long as your state requires, and stop the reminder sequence unless they get in touch.
Can an AI receptionist run recall calls?
ClinicEcho answers the phone rather than dialling out: when a patient replies to your recall text by calling at 12:30 or 7 pm, it books the hygiene visit into your slots, takes the "I have no insurance now" question with the answers you approve, and sends a transcript within a minute. Your software still sends the reminders. $497 a month, 14-day free trial, BAA signed first. Demo line: (602) 536-0014.
