How Often Should You Visit the Dentist in the UK? NHS and NICE Guidance

In the UK, most adults do not need a dental check-up every six months. Your dentist should set your next visit based on your oral health and risk. NICE guidance says the gap can be as short as 3 months or as long as 2 years for adults, and up to 1 year for under 18s. Ask your dentist why they chose your interval.

That answer surprises many people. The six month rule was a habit, not a rule for everyone. This guide explains how your interval is set, what changes it, what a check-up includes, what it costs on the NHS in England, and when to book sooner.

The short answer: there is no six month rule for everyone

There is no rule in the UK that everyone must see a dentist every six months. NICE, the National Institute for Health and Care Excellence, says the interval between oral health reviews should be set for each patient, based on disease levels and risk.

NICE guidance on dental checks says: “The time to your next check-up could be as short as 3 months or as long as 2 years, or up to 1 year if you are under 18.” It also says: “Generally speaking, the lower your risk of dental problems, the longer the gap will be before your next check-up.”

NHS England also supports personalised recall. It notes that NICE recommends an adjustable recall interval for adults, from a minimum of 3 months to a maximum of 24 months, for patients who have repeatedly shown they can maintain good oral health.

A large UK trial, INTERVAL, tested this. It found that a variable risk based recall interval was not detrimental to oral health, and it found no difference in oral health for patients allocated to a six month or a variable risk based interval, and no difference between 24 month, six month and risk based intervals for the 30 per cent of adults considered suitable to be recalled at 24 months by their dentist.

That does not mean you should wait 2 years without thinking. It means your interval should match your mouth, not the calendar.

How your dentist decides your interval

Your dentist looks at your teeth, gums and mouth at the check-up, and at your history. They then set a date for your next visit and discuss it with you. NICE says the interval may vary over time, as your health and lifestyle change.

Factors your dentist is likely to weigh include:

How many fillings you have had, and how fast new decay appears
Gum health, including bleeding, pocket depth, and gum disease
Plaque and cleaning, including how well you brush and clean between teeth
Smoking, and alcohol use
Diabetes, dry mouth, and medicines that affect saliva
Diet, especially sugar, acids, and frequent snacking
Braces, implants, dentures, crowns, and bridges
Age, and whether your teeth are still changing
Past pain, infections, or urgent treatment

If your dentist gives you a 3 month interval, it is not a punishment. It usually means they want to watch a problem closely, or treat it in stages. If they give you 12 or 24 months, it usually means your mouth is stable and low risk.

Ask one question at the end of every check-up: “What is my interval, and what would change it?” Write the answer down.

How often should you visit the dentist? A risk table

Use this table as a guide, not as a diagnosis. Your dentist sets your interval.

Your situation	Typical interval, estimated	Why
Adult, healthy mouth, no new decay, healthy gums, good cleaning	12 to 24 months	Low risk, stable over time
Adult, some fillings, occasional decay, gums bleed sometimes	6 to 12 months	Moderate risk, needs regular review
Adult, active decay, gum disease, or frequent problems	3 to 6 months	High risk, needs close monitoring and treatment
Adult who smokes, has diabetes, or has dry mouth	3 to 6 months, or as your dentist advises	Higher risk of decay and gum disease
Adult with braces, implants, or dentures	As your dentist advises, often 3 to 6 months at first	Appliances need extra checks
Adult with a new problem, pain, or treatment in progress	As your dentist advises, often within weeks	Treatment, not routine recall
Child or teenager under 18	Up to 12 months at most, often 6 to 12 months	Teeth are still developing, and decay risk is higher

NICE says the shortest interval for all patients should be 3 months for a routine oral health review. A recall of less than 3 months is not normally needed for a routine review. A patient may need to be seen more often for disease management, ongoing treatment, or emergency care, which are outside a routine review.

NICE also says practical recall intervals are 3, 6, 9 or 12 months for under 18s, and 3, 6, 9, 12, 15, 18, 21 or 24 months for adults aged 18 and over.

How often should children visit the dentist?

Children should be seen at least once a year, and usually every 6 to 12 months. NICE says the longest interval for patients younger than 18 should be 12 months.

That matters because decay can move fast in young teeth, and because early checks let a dentist spot problems, give fluoride, and check how teeth are coming through. A child who has had decay, or who is at higher risk, will usually be seen more often than a child with a healthy mouth.

Ask the practice about NHS charges and exemptions for children in your nation, as the rules differ across England, Wales, Scotland and Northern Ireland. Do not assume a charge is the same everywhere in the UK.

What happens at a dental check-up?

A routine check-up usually takes 20 to 30 minutes. It is not just a quick look.

Your dentist will usually:

Ask about your general health, medicines, and any pain or problems
Look at your teeth, gums, tongue, cheeks, and the inside of your mouth
Check for decay, gum disease, and signs of mouth cancer
Check old fillings, crowns, bridges, dentures, and implants
Take X-rays if they are clinically needed, not at every visit
Give advice on brushing, cleaning between teeth, diet, and fluoride
Tell you what treatment, if any, you need, and what it will cost
Set your next check-up date, based on your risk

A scale and polish is not automatic at every check-up. On the NHS in England, it is included in Band 1 only if it is clinically needed.

If you are nervous, tell the practice when you book. Ask what will happen first, and ask for a break if you need one. That is normal, and it helps the dentist plan the visit.

How much does an NHS dental check-up cost in England?

In England, a routine NHS dental check-up usually comes under Band 1. From 1 April 2026, the NHS dental charges in England are Band 1 £27.90, Band 2 £76.60, and Band 3 £332.10. Urgent care is £27.90.

Band 1 covers an examination, diagnosis, X-rays if clinically needed, a scale and polish if clinically needed, and advice on preventing future problems. You pay one charge per course of treatment, set by the highest band of work you need. You do not pay per filling or per visit within that course.

Charges differ in Wales, Scotland and Northern Ireland. Check the NHS guidance for your nation before you book. The next article in this series will cover NHS dental bands in full, with worked examples and who pays nothing.

Private check-up prices vary by practice. Ask for the price before you book, and ask what it includes.

Hygienist visits: are they separate?

Yes, sometimes. A dentist check-up and a hygienist visit are different appointments.

A hygienist focuses on gum health. They clean above and below the gum line, remove plaque and tartar, and teach you how to clean between teeth. Your dentist may refer you to a hygienist if you have gum disease, bleeding gums, or a build-up of plaque.

On the NHS, a scale and polish by a dentist is part of Band 1 only if clinically needed. A separate hygienist appointment may be private, or it may be part of a course of treatment. Ask the practice what is included, and what it will cost, before you book.

If your gums bleed when you brush, do not stop brushing. That is a sign to clean more carefully, and to ask for advice. A future article in this series will cover how to stop bleeding gums in 14 days, with a cause by cause table.

When should you book sooner?

Do not wait for your next recall if you notice a change. Book sooner if you have:

Tooth pain that does not settle, or pain that wakes you at night
Swelling in your face, mouth, or neck, or a fever with tooth pain
A broken tooth, a loose tooth, or a filling or crown that has come off
Bleeding gums that do not improve after 2 weeks of careful cleaning
A mouth ulcer that does not heal within 2 weeks
A change in your bite, or a new gap between teeth
Difficulty opening your mouth, swallowing, or breathing, seek urgent care

For urgent dental pain in England, call NHS 111 if you cannot get an urgent NHS dentist appointment, or if you are not sure what to do. For facial swelling with difficulty breathing or swallowing, or a serious injury, call 999 or go to A and E.

These are general signs, not a diagnosis. Your dentist or GP can assess you in person.
