## The Short Answer

Most practices already know who is overdue. The list sits in the practice management system and nobody has time to work it. An AI front desk with outbound calling and SMS can work that list steadily: text first, call the people who do not answer, offer real times, book the ones who say yes, and pass the awkward cases to your team.

What decides whether it works is the list you hand it, the pace you set, and the rules for what it may say.

## Who Counts as Overdue

There is no standard definition, so pick your own and write it down. A simple cut is by time away: recently overdue (a few months past due), longer overdue (a year or more since the last hygiene visit), and lapsed (gone long enough that you would treat them almost like a new patient). Each tier needs a different message. Someone two months late needs a nudge. Someone gone three years needs a friendlier opener and no mention of how long it has been.

For context, the CDC reports that 66.7 percent of US adults had a dental exam or cleaning in the past year, based on the 2025 National Health Interview Survey early release ([CDC NCHS](https://www.cdc.gov/nchs/fastats/dental.htm)). That leaves about a third who did not. It is a national figure and says nothing about your list, but it explains why every practice has an overdue pile.

## Clean the List Before Anyone Calls It

An overdue list is usually wrong in small ways, and every error becomes a wasted or embarrassing contact. Before outreach starts, remove or flag patients who have moved, transferred or died, anyone already scheduled (including appointments booked in the last few days), duplicate charts, do-not-contact patients, and anyone in a sensitive situation your front desk is handling personally, such as a billing dispute.

The right source for the list is your practice management system, not a spreadsheet someone exported last quarter. What a given integration can work from differs. The [Dentrix page](/integrations/dentrix/) describes Continuing Care and ASAP lists worked by voice, and the [iDentalSoft page](/integrations/identalsoft/) describes outbound recare calls on the list iDentalSoft generates from procedure-code intervals. Check the page for your own system before assuming anything.

## What the Evidence Says About Reaching Out

A randomized field experiment worked with a German dentist and sent patients due for a check-up either no reminder or a reminder postcard. Within one month, 19.3 percent of reminded patients had contacted the practice and scheduled a check-up, against 8.9 percent of the patients who got nothing. A hundred days later, 30.5 percent of reminded patients had actually had a check-up, against 22.4 percent of the control group. Adding information about the benefits of prevention did not improve the response, and repeated reminders worked about as well as the first ([Altmann and Traxler, IZA Discussion Paper 6699, 2012](https://docs.iza.org/dp6699.pdf), later published in the *European Economic Review*, 2014).

It was one practice in Germany, the reminder was a postcard and not a call or a text, and the study says nothing about AI. It does show that a plain reminder moves people who would otherwise drift.

There is also a reason to bother with the work. The CDC notes that gingivitis is reversible, but that left untreated it can progress to periodontitis ([CDC](https://www.cdc.gov/oral-health/about/gum-periodontal-disease.html)). Professional cleanings are part of how the early stage is managed, which is a better reason to call an overdue patient than a gap in your schedule.

## What Happens on the Call

This is the sequence to expect, and the points to check when you test it.

1. It identifies the practice and asks for the patient by name. It does not state anything about their care to a person who has not confirmed who they are.
2. It tells the patient why it is calling: they are due for a hygiene visit.
3. It offers two specific times from your real availability rather than asking "when would suit you?"
4. If the patient says yes, it books the visit, confirms it and sends a text with the details. Where your integration supports writing to the schedule, the appointment appears there.
5. If the patient says "not now", it asks whether to try again in a few weeks and records the answer.
6. If the patient has moved or switched practices, it marks the record for your team rather than arguing the point.
7. If the patient asks about cost or insurance, it takes the details and passes them to your team. It should not promise coverage.
8. If the patient says to stop calling, the request is honored on every channel.
9. If nobody answers, it leaves a short voicemail with the practice name and number and nothing about treatment, then sends a text.

On the voicemail, HHS guidance says providers may leave appointment messages but should limit what they disclose, for instance only the practice's name, number and what is needed to confirm an appointment, or a request to call back ([HHS](https://www.hhs.gov/hipaa/for-professionals/faq/198/may-health-care-providers-leave-messages/index.html)).

Whether patients are told they are speaking to an AI is your choice, and it affects trust. [Should the AI tell callers it is an AI](/blog/should-ai-tell-callers-it-is-ai/) sets out the argument.

## The Text Sequence

A reasonable pattern is a first text, a reminder a few days later, and a call to anyone who has not replied. [AI dental recall, reminders and confirmations](/blog/ai-reminders-confirmations-recall-outreach/) argues for spreading attempts over about two weeks and moving patients who ignore two contacts to a slower track. Every message should give the patient something to act on, such as two times to reply to.

## What Your Practice Needs to Set Up

You make a short list of decisions before the first contact goes out.

1. Define the overdue tiers and the oldest lapse you want to contact.
2. Name the exclusions: the do-not-contact list and the special cases.
3. Decide which appointment types the outreach may book, and with which hygienists or columns.
4. Set the hours of day for calls and texts, in the patient's local time.
5. Approve the wording of the text, the call opener and the voicemail.
6. Agree how consent and opt-outs are recorded, and who can see the record.
7. Say who reads the dashboard each morning and what they do with a "call me" request.

[What to hand over before go-live](/blog/what-to-hand-over-before-go-live/) covers the wider set of rules a new system needs, and several of them apply here.

## Pace the Outreach to Your Open Chairs

If 60 patients say yes but you have 12 open hygiene slots a week, it takes five weeks to seat them, and the patients you push months out will not be pleased. Count your open hygiene slots over the next six to eight weeks and set the daily volume of contacts so that bookings arrive about as fast as you can seat them. Work the tiers in order, starting with the recently overdue.

## A Worked Example With Your Own Inputs

The inputs below are assumptions chosen to show the arithmetic. They are not benchmarks and they are not a result from any practice.

- 400 patients on the overdue list after cleaning
- A hygiene visit worth $150 to the practice
- A share of the list that books, which is the number nobody knows until they measure it

| Share of the list that books | Appointments | Production at $150 |
|---|---|---|
| 5 percent | 20 | $3,000 |
| 10 percent | 40 | $6,000 |
| 15 percent | 60 | $9,000 |

Put your own list size and visit value in, and treat the booking rate as the figure you are going to find out. A hygiene visit can also surface treatment that gets scheduled afterwards. If you track that, count it separately and be honest about how much of it you can attribute to the outreach.

Reactivated patients may attend differently from patients who never lapsed, so watch their attendance as its own group. The confirmation steps in [what no-shows cost a dental practice](/blog/dental-no-show-cost-and-how-ai-confirmations-help/) apply directly.

## Compliance

HIPAA allows appointment reminders as part of treatment. Automated calling and texting fall under separate consent rules. In February 2024 the FCC ruled that AI-generated voices count as "artificial" voices under the Telephone Consumer Protection Act, so calls that use them need the consent that law requires ([FCC](https://docs.fcc.gov/public/attachments/DOC-400393A1.txt)). Have your outbound program reviewed by someone qualified before you scale it. This is not legal advice.

## What Is Included With GetHelpdesk.AI

[GetHelpdesk.AI](/) is a single $399 a month plan that includes inbound and outbound calling, SMS follow-ups, a website chatbot that books, reschedules and cancels in your practice management system, and a dashboard of every call. It covers up to 600 inbound calls a month, 25+ languages, and works with DSOs. Integrations are listed on the [integrations pages](/integrations/), and the [pricing page](/pricing/) has the current terms.

## Key Takeaways

- Define overdue yourself, split the list into tiers, and clean it before any contact goes out.
- A randomized study with a German dentist found that reminders raised check-up scheduling from 8.9 to 19.3 percent within a month. It used postcards at one practice, so treat it as direction, not a forecast.
- On the call, expect real times offered, booking where your integration allows, a clean handoff for cost questions, and opt-outs honored everywhere.
- Pace outreach to your open hygiene chairs, or you will over-promise.
- The worked example is arithmetic on assumed inputs. Your booking rate is the number to measure.
- Get consent and opt-out handling reviewed before you scale.

## Frequently Asked Questions

**How long before patients start booking?**

That depends on your contact pace and how many hygiene slots are open, so plan in weeks. Read the dashboard daily for the first fortnight so you catch problems early.

**Will it call people who have already booked?**

It should not, and you should test that. The list needs to come from live schedule data, and anyone booked recently should be excluded. Ask to see this working before you go live.

**Can it work unscheduled treatment as well as hygiene recall?**

Some lists, such as the ASAP or unscheduled lists in certain systems, can be worked. Check the integration page for your system, and start with hygiene recall because the rules are simpler.

**What should I measure?**

Appointments booked per contact, how many of those patients attend, and the opt-out rate. A rising opt-out rate means you are contacting too much.

## Where to Start

Run one report: active patients who are overdue for hygiene, with the date of their last visit. Split it into tiers, count your open hygiene slots for the next two months, and decide how many contacts a day you can absorb. Then [see how GetHelpdesk.AI works](/) or [talk to us about your recall list](/contact/).
