Dental recall: NICE intervals and a system that works

Dental recall is the system a practice uses to invite patients back for their next check-up, properly called an oral health review, at an interval the dentist sets for each patient. In the UK the reference point is NICE guideline CG19, which says the interval should be based on each patient's risk, from 3 months up to 24 months for adults. This guide covers what dental recall means, what the NICE guidelines on dental recall intervals actually say, why "every six months" is a habit rather than a rule, and how to run a recall system that keeps patients coming back.

What is a dental recall?

A dental recall is the planned return visit for a routine examination. The dentist decides the interval at the end of a check-up or a course of treatment, it is recorded on the patient's file, and the practice contacts the patient when it falls due. "Recall" is also used for the whole process: the interval, the reminders, the follow-ups and the list of patients who are overdue.

It is separate from treatment appointments, hygiene visits booked for specific clinical reasons, and emergency care. Those happen as needed. Recall is the routine that keeps a patient under review between them.

What the NICE guidelines on dental recall say

NICE guideline CG19, Dental checks: intervals between oral health reviews, is short and clear. Its key recommendations:

• The interval "should be determined specifically for each patient and tailored to meet his or her needs", based on an assessment of disease levels and risk.
• The assessment should combine the evidence with the dental team's clinical judgement and be discussed with the patient.
• The shortest interval for routine recall is 3 months.
• The longest interval is 12 months for patients under 18 and 24 months for adults.
• The dentist should record the recommended interval and the patient's agreement or disagreement with it.
• The interval should be reviewed at the next oral health review and adjusted in light of what happened.

For practical reasons NICE suggests a fixed set of intervals:

NICE explains that the 12-month ceiling for children reflects evidence that decay can progress faster in children and adolescents, and that intervals longer than 24 months for adults are undesirable because they could weaken the relationship between dentist and patient. It also says patients should understand that, just as with a six-month recall, there is no guarantee new disease will not develop between visits.

Practices in Scotland and Northern Ireland should check the guidance that applies to their own health service as well.

What is a 6-month recall at the dentist?

A 6-month recall means inviting a patient back for a check-up every six months. It became the default for decades, and many patients still expect it. It is one of the intervals NICE lists, but NICE does not recommend it for everyone. The NHS website tells patients that while they may assume they should have a check-up every six months, the time between check-ups can vary from 3 months to 2 years, and people with good oral health will probably need to attend only once every 12 to 24 months.

The evidence for tailoring intervals comes partly from the INTERVAL trial, run in UK dental practices. NHS England summarises its finding that a variable, risk-based recall interval was not detrimental to patients' oral health, with no difference found between six-month and risk-based intervals.

NHS dental recall in practice

NHS England has encouraged practices to use NICE recall intervals to free capacity. Its published case study describes a practice that moved NHS patients to personalised intervals so that appointments could go to those with the highest need. Its practical tips are worth repeating:

• Make sure every team member knows how recall decisions are made, so they can explain them to patients.
• Patients tend to accept a longer interval when reassured it is safe and that they can ask for an earlier appointment if something changes.
• Stagger recalls to manage numbers and focus on the patients most in need.

The front desk matters as much as the clinician here. A patient told "the dentist says you don't need to come back for 18 months" without an explanation may hear "we don't want to see you". A patient told "your mouth is healthy, so you can safely leave it longer, and call us any time if anything changes" hears good news.

How often should you go to the dentist for a cleaning?

There is no single answer. NICE CG19 covers the interval between oral health reviews, not hygiene appointments. How often a patient sees the hygienist is a clinical decision based on their gum health and risk, so it varies from patient to patient. For your recall system, the practical point is to record hygiene intervals separately from examination intervals, so one does not silently overwrite the other.

How to run a dental recall system that works

1. Set the interval every time. At the end of each oral health review or course of treatment, the clinician sets and records the interval and the patient's agreement, as NICE recommends.
2. Decide your booking model. Either book the next check-up before the patient leaves, or send a reminder when it falls due and let them book. Booking ahead usually suits short intervals. Reminding usually suits intervals of a year or more, when diaries and lives change.
3. Send the first reminder on time. Ideally a few weeks before the due date, so patients can choose a time that suits them.
4. Follow up in steps. A second reminder if there is no response, then a different channel, such as a letter or a call from the front desk.
5. Work the overdue list weekly. One person owns it, with a fixed slot in the diary.
6. Keep the data clean. Wrong numbers, people who have moved away and patients who have died should be marked promptly so they stop receiving messages.
7. Review intervals at each visit. NICE expects the interval to change as the patient's risk changes. Your system should make that easy.

Recall messages and the rules

Recall reminders are part of a patient's ongoing care, but they still need care in how they are written. The ICO treats messages that confirm or remind people about appointments as service messages, which are not direct marketing. It also says that if a message "actively promotes or encourages people to make use of a particular service, special offer, or upgrade", it is likely to be marketing, and that phrasing, tone and context decide which side a message falls on.

So keep recall messages neutral and factual: the practice name, that the check-up is due, and how to book. Leave out offers and promotions, which belong in separate marketing messages sent only to patients who have agreed. And leave out clinical detail, because the ICO says appointment details and reminders can count as health data when they reveal something about a person's health.

What to measure in your recall system

There is no official benchmark for recall performance, so compare your practice with itself over time. Four measures cover most of it:

That last group is where recall turns into reactivation. A patient who has missed one reminder is usually just busy. A patient who has missed a whole cycle needs a different approach, and it is worth treating them as a separate list with its own messages and its own owner.

Recall keeps patients, search finds new ones

A good recall system protects the patient base you have. It does not replace the patients who move away, which is why practices need a steady flow of new patients as well.
