NICE Dental Recall Intervals: 3 to 24 Months Explained for UK Practices

NICE dental recall intervals run from 3 to 24 months for adults and from 3 to 12 months for under-18s. They come from NICE guideline CG19. The dentist sets each patient's interval by their risk of dental disease, rather than giving everyone a fixed six-month check-up. For NHS patients aged 18 and over in England, the chosen interval must also be recorded on every FP17 claim.

Ask most patients how often they should see a dentist and they will say "every six months". That advice is out of date. Some patients need to be seen every three months. Others can safely wait up to two years. This guide explains the rules, where they come from, what the NHS now expects you to record, and how to run personalised recalls without burying reception in admin.

It is written for principals and practice managers, not clinicians. The clinical decision is always the dentist's. This is the operational side: what the guidance says, what the NHS checks, and how to make it work in a busy book.

What is a dental recall interval?

A recall interval is the time between one oral health review, or check-up, and the next. It is the gap the dentist recommends before they want to see a patient again. "Recall" means the practice contacts the patient to invite them back when that time is due.

For years the default was six months for almost everyone. The current approach is different. The interval should fit the patient in front of you. A healthy adult with good oral hygiene does not need the same schedule as a smoker with gum disease.

NICE CG19: the end of the fixed six-month check-up

The main source is NICE, the National Institute for Health and Care Excellence. Its guideline CG19 is now titled "Dental checks: intervals between oral health reviews". It was published on 27 October 2004 and it still sets the rules today.

The headline point is simple. There is no strong evidence that six months suits everyone. So NICE asks the dental team to set the interval from each patient's disease levels and risk. You can read the NICE CG19 recommendations in full.

What recall intervals does NICE recommend?

NICE gives a range, and the dentist picks a point within it for each patient:

• Shortest interval, all patients: 3 months. NICE says a routine recall of less than 3 months "is not normally needed".
• Longest interval, adults aged 18 and over: 24 months.
• Longest interval, under-18s: 12 months, because decay can progress faster in children and young people.

NICE also sets the steps to use. For practical reasons, a patient under 18 should be given an interval of 3, 6, 9 or 12 months. An adult should be given 3, 6, 9, 12, 15, 18, 21 or 24 months. Those fixed steps make recalls far easier to run, because every interval is a multiple of three months.

A 24-month interval is not a default for healthy adults. NICE says intervals can be extended up to 24 months for patients who have "repeatedly demonstrated that they can maintain oral health" and are not at risk. It also says intervals longer than 24 months are undesirable.

How a dentist decides the interval

This patient-by-patient approach is often called risk-based recall. The dentist weighs how likely the patient is to develop disease, and how serious it would be if they did. The higher the risk, the shorter the gap.

Factors that often pull an interval shorter include:

• A history of tooth decay or gum disease.
• Smoking or heavy alcohol use.
• A high-sugar diet.
• Poor oral hygiene or heavy plaque.
• A dry mouth, which some medicines cause.
• Medical conditions that affect the mouth.

NICE also asks for two things that are easy to forget. The dentist should discuss the interval with the patient and record it, along with whether the patient agreed. And the interval should be reviewed at the next check-up, then shortened, kept or lengthened based on how things went. The interval is a living decision, not a label for life.

What the NHS expects you to record

For NHS work in England, the recall interval is not just good practice. It is part of the claim. Since 1 October 2022, the recommended recall period must be recorded on every FP17 claim for a patient aged 18 or over. It goes in the NICE Guidance field and should be between 3 and 24 months. It is optional for under-18s and does not apply to treatment on referral. The NHS Business Services Authority sets this out.

The same 2022 changes added other clinical fields to the FP17. They include the highest BPE sextant score and the number of untreated decayed teeth, both covered in our guide to the FP17 clinical data set. Our guide to NHS dental bands and UDAs covers what else goes on the claim.

Risk-based recall is also part of the 2026 NHS contract changes. NHS England's guidance for the new care pathways says a patient should get an assessment to set "the clinically appropriate interval for a risk-based recall" when their pathway ends. So recall intervals will stay firmly on the NHS agenda.

All of this is why clear records matter. Good patient records let a dentist show why an interval was chosen, what the patient agreed, and when the risk was last reviewed.

Why spreadsheets struggle with personalised recalls

Here is the practical problem. Once every patient can have a different interval, a single "six-month list" no longer works. One patient is due in three months, the next in nine, the next in two years. Tracking that by hand is slow and easy to get wrong. Patients slip through and stop coming back.

That is where dental recall software earns its place. A good system stores each patient's own interval, works out the next due date and prompts the practice automatically. Instead of reception scanning a list, the software shows exactly who to contact this week. Our comparison of practice software and spreadsheets shows where manual lists break down.

DentiPoint does this as part of one practice-management system. Each recall type has a default interval, which you can override for an individual patient, and the system works out when they are due. It then sends the invitation by email, SMS or WhatsApp, depending on the channels your practice uses.

A simple recall workflow that keeps patients coming back

You do not need a complicated process. Most well-run practices follow a version of these steps:

Run hygiene recalls the same way. A dental hygiene recall system should give each patient their own hygiene interval alongside the exam interval, so a patient due for a scale and polish is prompted on their own cycle rather than whenever they next see the dentist.

1. Set the interval at the appointment. The dentist picks it from the NICE steps and records it, with the patient's agreement, before the patient leaves.
2. Store it on the patient record. The interval lives in one place, not in someone's head.
3. Let the system track the due date. When the recall is due, the patient appears on a due list on their own.
4. Send a friendly invitation. Automatic recall reminders invite the patient to book, with a link to book online.
5. Follow up non-responders. A second nudge a couple of weeks later catches people who missed the first.
6. Review at the next visit. The dentist confirms, shortens or lengthens the interval.

Patients who drift well past their due date need a different approach. Our guide to reactivating lapsed dental patients covers the outreach. Once a patient has booked, a well-timed reminder helps reduce no-shows, which protects both your income and the NHS activity you are contracted to deliver.

Frequently asked questions

What is the NICE recall interval for adults?

Between 3 and 24 months, set by the dentist according to the patient's risk. NICE lists the steps as 3, 6, 9, 12, 15, 18, 21 or 24 months for adults. Only patients who have shown over time that they can keep their mouth healthy should move towards the 24-month end.

Do NHS patients still need a check-up every six months?

No. Under NICE CG19 there is no fixed six-month rule. The dentist sets an interval based on risk, which can be as short as 3 months or as long as 24 months for an adult.

What is the longest recall interval allowed?

NICE recommends a maximum of 24 months for adults and 12 months for anyone under 18. These are ceilings, not defaults. The interval is reviewed at each check-up.

Do we have to record the recall interval on the FP17?

Yes, for NHS patients aged 18 or over in England, on claims with an acceptance date on or after 1 October 2022. It goes in the NICE Guidance field and should be between 3 and 24 months. It is optional for under-18s and does not apply to referrals.

What is NICE CG19?

It is the NICE clinical guideline "Dental checks: intervals between oral health reviews", published in October 2004. It recommends risk-based recall intervals instead of a fixed schedule, and it is the main reference UK dentists use.

How does a recall differ from an appointment reminder?

A recall invites a patient to book their next check-up when it becomes due. A reminder is sent before an appointment they have already booked, to help them turn up. Most practices use both, and a good system automates each one.

Risk-based recall is better for patients and expected by the NHS. The hard part is running it at scale, and that is a systems problem more than a clinical one. To see per-patient recalls working on your own book, get started with DentiPoint or compare plans on our pricing page.
