How to reduce failed dental appointments: a UK practice guide

Failed dental appointments, where a patient does not turn up and does not cancel in time, cost a practice the clinical hour and, for NHS work, the UDAs that hour would have earned. Most practices reduce them with four things: booking appointments patients have actually agreed to, reminders that make it easy to cancel or move, a written policy applied the same way every time, and a short list to fill gaps at short notice.

The rules differ for NHS and private patients, and getting them wrong causes complaints. This guide covers both.

What is considered a missed appointment?

A missed appointment, also called a failed to attend (FTA) or did not attend (DNA), is one where the patient does not come and has not cancelled. Most practices also track short-notice cancellations, where the patient cancels too late for the slot to be reused. Your policy should define both, including how much notice counts as enough and how late a patient can arrive before the appointment is treated as missed.

For NHS patients this definition is not optional. The NHS Business Services Authority says a practice must have an agreed fail to attend and short-notice cancellation policy, that all staff must know and follow it, and that it exists so missed and late-cancelled appointments are handled in a consistent, fair and transparent way.

Measure your failed appointment rate

Before changing anything, measure it for a month:

• FTA rate: failed appointments divided by appointments booked.
• Short-notice cancellation rate: late cancellations divided by appointments booked.
• Slots refilled: of the gaps those created, how many you filled.

Then split by appointment type, clinician, day and time, and how far ahead the appointment was booked. The pattern usually points to the fix. Appointments booked many months ahead, recall check-ups and first appointments for new patients are common places to look.

What happens if a patient misses an NHS dental appointment?

An NHS patient in England cannot be charged a fee for missing an appointment. The NHS website tells patients an NHS dentist should not charge a fee for missing NHS dental appointments. It also tells them that if they miss an appointment for ongoing treatment without letting the practice know, they may need to pay again for a new course of treatment.

That second point comes from the contract. Under paragraph 6 of Schedule 3 to the GDS contract regulations, if a course of treatment is not completed within a reasonable time, any further NHS care must be provided as a new course of treatment. Where a patient repeatedly fails to attend for planned care, the NHS Business Services Authority says the practice can claim the course as incomplete treatment, following what its contract with the commissioner says about how many missed appointments are allowed. It also warns that incomplete treatment claims are monitored and unusual patterns are reported to the commissioner.

Whether you can decline to offer further NHS appointments after repeated failures depends on your contract and your commissioner's policy. Check with your ICB before writing a limit into your policy.

Can you charge private patients for a missed appointment?

Yes, if the fee is in terms the patient agreed to in advance and it is fair. Consumer law limits what you can charge. The government's guidance on writing fair contracts says a cancellation fee must not be excessive and should reflect the steps you can take to reduce your losses, that disproportionately high charges for breaching a contract are likely to be unfair, and that a term with a significant effect on the customer must be made prominent rather than buried.

In practice that means:

• the fee is shown clearly when the appointment is booked, not only in small print
• it is proportionate to the time lost, and lower if you are likely to refill the slot
• it is applied consistently, with discretion written into the policy for genuine emergencies
• deposits for long private appointments are explained up front, including when they are refunded

In a mixed practice, be careful that a fee on private appointments is never applied to NHS appointments, and that reception can tell the difference at a glance.

Reminders that reduce failed appointments

Reminders are the single most common fix. A few principles make them work better:

1. Confirm at booking. Send the time, date, clinician and address straight away.
2. Remind twice for long gaps. A recall booked months ahead needs a reminder well before the day and another close to it.
3. Make cancelling easy. A reply option or a link to move the appointment gets you the slot back. A reminder that says "call us during opening hours to cancel" often produces a no-show instead.
4. Ask for confirmation for long or expensive appointments, and follow up by phone if there is no reply.
5. Use the patient's preferred channel. Text for most, email or a call for some.

A reminder that only confirms or reminds about an appointment is a service message, not marketing. The ICO's guidance lists appointment reminders as an example, but warns that a service message which also promotes something counts as direct marketing. Keep offers out of your reminders.

Better booking prevents most no-shows

• Book a time the patient chose. An appointment allocated without asking is easier to forget.
• Avoid booking too far ahead where you can. Some practices send a recall invitation when the patient is due rather than booking a fixed slot months in advance.
• Explain why the next visit matters, especially mid-treatment. A patient who understands the next stage is more likely to come.
• Ask about barriers. Work, childcare, transport and anxiety are common reasons people miss appointments. An earlier or later slot, or a note that the patient is nervous, can solve it.

Fill the gaps you cannot prevent

Some failures will always happen. Keep a short-notice list of patients who want an earlier appointment, by clinician and treatment length, and work it whenever a slot opens. Hygiene appointments and short reviews are often the easiest to refill. Track how many gaps you fill, because a high refill rate means late cancellations cost you little.

Write a fair failed appointment policy

A clear policy protects you and treats patients consistently. It should cover:

1. What counts as a failed appointment and as a short-notice cancellation.
2. How patients are told about the policy, at registration and when booking.
3. What happens after a first and a repeated failure, separately for NHS and private patients.
4. Any private fee, its amount and when it is waived.
5. How you make reasonable adjustments for patients who need them, such as people with disabilities, learning difficulties or anxiety.
6. Who can apply discretion, and how decisions are recorded.

Publish it on your website and in the practice. Patients who know the policy from the start rarely argue with it later.

Check whether it is working

Give any change at least a couple of months before judging it, and compare like with like: the same months, the same appointment types. Keep three numbers on the monthly practice report:

• FTA rate, by appointment type
• short-notice cancellations, and the share of those slots refilled
• clinical hours lost to gaps nobody filled

If the FTA rate falls but unfilled hours do not, the problem has moved from no-shows to late cancellations, and the fix is a faster short-notice list rather than more reminders.

Common questions about missed appointments

Is there an NHS fine for missed dental appointments?

No. There is no fine or fee for NHS dental patients who miss an appointment, and the NHS website tells patients a dentist should not charge one. The consequence is that an unfinished course may need to restart as a new course, with a new charge.

What is it called when you miss an appointment?

Practices usually call it a failed to attend (FTA) or a did not attend (DNA). The NHS Business Services Authority uses "failed to return" when a patient stops coming back to complete a course of treatment.

Why it matters more on an NHS contract

On an NHS contract, a failed appointment is not just lost time. It is UDAs you still need to deliver by the end of March. Under NHS England's Policy book for primary dental services, delivering below 96% of contracted activity at year end means money is recovered. Since April 2026, NHS England's contractual guidance on the dental reforms also lists taking steps to reduce missed appointments among the things commissioners consider before using their discretion to reduce a practice's urgent care requirement. Our study of NHS contract delivery and values shows how many contracts run behind pace.

A practice that cuts failed appointments frees diary time, and that time is worth more when the diary is full of patients who chose you. The guide on getting more dental patients covers how to fill it.
