Free and low-cost NHS dental options when sensitivity needs a professional look.

The cheapest way to get a professional look at sensitive teeth in the UK is an NHS dental examination, which in England is a Band 1 charge of £27.90 as shown on nhs.uk on 10 September 2026, and which costs nothing for large groups of people, including anyone under 18, anyone who is pregnant or has had a baby in the last 12 months, and people who get certain benefits¹². You do not have to be on a practice's list first: the NHS says you can contact any NHS dentist and ask for an appointment, and NHS 111 advises on urgent dental care when you have no dentist or cannot get through to one³⁴. That examination costs £7.91 more than a £19.99 tube of S3 Sensitivity Science™ and a little less than two tubes at its £14.99 subscription price, prices that may change, so check the site; only one of the two can find a crack, a failing filling or decay.

What does an NHS dental examination cost, and what does it include?

In England a routine examination is a Band 1 treatment, and Band 1 was £27.90 on both the NHS charges page and the NHS Business Services Authority (NHSBSA) dental costs page when this page read them on 10 September 2026¹⁶. The NHS lists what Band 1 can include: an examination, assessment and advice; X-rays if clinically needed; fluoride put on the surface of the teeth; simple management of gum disease, such as scaling, if clinically needed; moulds of the teeth; and small adjustments to dentures or braces¹.

Band 2, at £76.60, adds fillings, root canal treatment and extractions, and Band 3, at £332.10, adds crowns, dentures and bridges¹. A course of treatment carries one charge, that of the highest band in it, even when the work takes more than one visit, and the NHSBSA adds that a dentist may collect it in instalments¹⁶. If you need more treatment within two months and it falls in the same band or a lower one, you pay nothing extra¹. Three things are free even for people who pay: having stitches removed, having bleeding from the mouth stopped, and having dentures repaired¹.

One paragraph on the NHS page did not agree with the rest of it on the day. Its note on gum treatment says scaling is usually included in Band 1 at £27.40 and that complex gum treatment may be charged as Band 2 at £75.30, while the band headings on the same page read £27.90 and £76.60¹. The NHSBSA page prints £27.90 and £76.60⁶. This page reports both and leaves it there; if the difference matters to you, ask the practice what it will charge before treatment starts.

You should not be surprised by the bill. The NHS says the dentist should tell you which treatments you may need, why, and what they will cost, and that Band 2 and Band 3 treatment should come with a written treatment plan to sign before it starts⁸. Plans are not usually given for Band 1 or urgent treatment, though you can ask for one⁹. The same NHS page lists what should not happen: a deposit taken before your mouth and teeth have been assessed, a private fee for an appointment to see whether you will be accepted for NHS care, or a fee for missing an NHS appointment⁸. Missing an appointment in the middle of a course without telling the surgery can mean paying again for a new course, so ring if you cannot make it⁸.

Nor is a check-up a fixed six-monthly bill. NICE's guideline on the gap between dental reviews sets it for each person, from three months to 24 months for adults, based on the state of their teeth and gums and their risk, and it lists the financial cost to the patient of the review and any treatment among the things the dental team should discuss¹⁰. The NHS check-up page repeats the range and says people with good oral health will probably need to attend only every 12 to 24 months¹¹.

Who pays nothing, or less?

In England, NHS dental treatment is free if, when it starts, you are under 18, or under 19 and in full-time education; pregnant or have had a baby in the last 12 months; have had a stillbirth in the past 12 months; being treated by a hospital dentist in an NHS hospital; or receiving War Pension Scheme or Armed Forces Compensation Scheme payments and the treatment is for your accepted disability²¹². Benefits count too, when you or your partner receive them. The NHS page lists income-related Employment and Support Allowance, Pension Credit Guarantee Credit, and Universal Credit where income is below a set amount among them, and dependants under 20 on the claim are covered as well². Pension Credit Savings Credit on its own does not qualify, the NHSBSA says¹².

You will be asked for proof. The NHS gives examples: a valid HC2 certificate, your birth certificate, a maternity exemption certificate or a MatB1 form². The NHSBSA also warns that claiming free treatment you are not entitled to can bring a penalty charge of up to £100, so check before you sign the form at the practice¹². Its online eligibility checker is linked from the same page.

If none of that applies and money is short, the NHS Low Income Scheme may pay all or part of the charge. You cannot use it if you, your partner or both of you have more than £16,000 in savings, investments or property, not counting your home, and with more than £6,000 the application goes on paper rather than online⁵. The NHSBSA compares your weekly income with your weekly needs and usually decides within 18 working days: an HC2 certificate gives full help with health costs, including free NHS prescriptions, and an HC3 certificate shows how much you still pay⁵. A certificate usually lasts between six months and five years, depending on circumstances⁵.

Paid already, then found out you qualified? The NHSBSA says a refund can be claimed when you have paid NHS dental charges and then find you were entitled to free or reduced-cost treatment, and the claim has to be made within three months of paying; in England it goes by email, or by post on form HC5(D)⁶. Anyone applying to the Low Income Scheme after paying for treatment can ask for the refund in the same application⁵¹³.

Every route to a dentist's view, and what it costs

There are more doors than most people expect, and they do different jobs. The table gives each one with its cost in England as shown on the day it was read, how to reach it, and what it can and cannot do for teeth that hurt with cold or sweet things. No toothpaste is a row: none of them is a way to see a dentist.

Two of those rows need more words. Since 2013, dental hygienists and dental therapists have been able to carry out their full scope of practice, apart from tooth whitening, without a referral from a dentist, and the General Dental Council expects them to refer patients on to a dentist for treatment only a dentist can provide¹⁵. On the NHS, scaling that a dental professional says is clinically needed can be done by a hygienist or a dental therapist within Band 1, and scaling that is not clinically needed has to be paid for privately¹. No private hygienist price appeared on any page read for this article, so none is given; the page on whether a hygienist can help with sensitive teeth covers what that appointment involves.

Dental hospitals are not a walk-in alternative either. Treatment from a hospital dentist in an NHS hospital is free under the NHS rules, although dentures or bridges may still be charged². King's College Hospital in London, for one, says its acute dental care is for adults with severe dental problems who have been assessed by NHS 111's London Dental Triage, that it takes no routine referrals, and that patients are seen by dental students and junior clinical staff under senior supervision, with fewer patients seen in university holidays¹⁴. In a four-week questionnaire survey of 1,058 patients at the same hospital's dental emergency clinic, published in 2015, 51% had tried to make an appointment with a dentist before they came, and people who went to a dentist irregularly were more likely than regular attenders to say cost had affected their past dental care¹⁷.

Is a toothpaste like S3 a cheaper first step than a check-up?

Only if the check-up was never needed, and a tube cannot tell you whether it was. On the day this page was read, a Band 1 examination in England cost £27.90¹; a tube of S3 cost £19.99, or £14.99 on subscription, and those prices may change, so check the site.

The sum is short. The examination costs £7.91 more than one tube of S3 at the one-off price, and £2.08 less than two tubes on subscription. The page on what sensitivity toothpaste costs per day does the sums for the tubes themselves.

What the difference buys is the part no tube does. At an NHS appointment, the dental professional looks for signs of decay, gum disease and mouth cancer, may use a probe, a small device that blows air and a mirror, asks about symptoms such as pain, and may take X-rays⁸. Those checks are what separate sensitivity from the problems that feel like it: the NHS lists tooth decay, a cracked or damaged tooth and a loose or broken filling among the causes of toothache¹⁶, and a 2019 clinical review for dentists in UK primary care explains that the symptoms people describe as sensitivity have more than one possible cause, which makes a firm diagnosis difficult¹⁸. The guide to what a dentist checks for sensitive teeth walks through the appointment.

The NHS bands also pay for treating sensitivity itself. The urgent charge covers treatment of sensitive teeth affecting the parts of the tooth called the dentine or cementum, and Band 1 includes putting fluoride on the surface of the teeth¹. A dentist can also prescribe a higher-strength fluoride toothpaste: the British National Formulary lists 2,800 ppm and 5,000 ppm fluoride toothpastes, with doses for preventing tooth decay, the 5,000 ppm strength from the age of 16¹⁹. Their listed use is preventing decay rather than easing sensitivity, and whether one suits you is the dentist's call.

Urgent care costs a person more than the band charge. In a cross-sectional study of 714 people attending urgent dental care in North-East England, published in 2023, the average personal cost of attending, counting travel, appointment fees, childcare, medicines and time away from work, was £85.81, and the centralised emergency clinic cost people the most while their own dental practices cost the least²⁰. Those figures come from people already sitting in urgent care, with nobody who booked earlier to set them against, so they show what an urgent visit cost, not what waiting added.

No NHS dentist can prescribe S3, which is sold from its own website. Nothing on this page is a reason to buy a tube instead of booking, and if your pain lingers after the cold has gone, wakes you at night, sits in one tooth or comes with swelling, a toothpaste of any kind is the wrong thing to spend the money on.

What if you cannot find an NHS dentist?

Keep using the NHS routes, because they are built for exactly this. The NHS says you may find it difficult to find a local dentist offering NHS appointments, that you can contact any NHS dentist, that some practices offer both NHS and private appointments, so you should ask for an NHS one, and that you may be asked to join a waiting list³. Filling in a registration form at a first visit does not mean that practice will always be able to give you NHS care in future³. If you cannot find one, contact your local integrated care board (ICB), which manages dental services in your area and may be able to tell you where to get an appointment³.

Access really is uneven. A 2024 neighbourhood-level analysis of NHS dental contracts across England for 2022–23 counted 1.53 units of dental activity per person, the measure those contracts use, in which an examination counts as one unit, and its author concluded that NHS dental provision was generally less than basic care for the population would need⁷. The same analysis found availability and access by car better, not worse, in more deprived neighbourhoods, and access by car poor in rural ones⁷. When one Bristol practice closed in June 2023, its model showed provision falling in the neighbourhoods around it as well as its own⁷. It measured car travel only, left private dentistry out and did not look at waiting times, and this page makes no claim about waiting times either.

If you are in pain, a routine place is not the only way in. The NHS says to ask for an urgent or emergency dental appointment, or get advice from NHS 111, if you have severe tooth or mouth pain that is affecting your sleep or daily activities and is not helped by paracetamol or ibuprofen, pain that painkillers ease but that is not going away, or a broken or loose filling or crown, among other reasons; urgent treatment should be offered within 24 hours or seven days depending on your symptoms⁴. In England that appointment was £27.90 on the day¹. While you wait, a pharmacist can advise on painkillers and on toothache itself⁴. The page on sensitivity with swelling or a bad taste sets out the signs of infection, and the guide to what helps tooth nerve pain tonight covers the hours before an appointment.

The GP surgery is where people turn when the dental door seems shut, and it does not lead to dental treatment: the NHS toothache page tells you not to go to your GP, because a GP cannot give it¹⁶. When a retrospective cohort study went through the records of 288,169 dental consultations with UK family doctors from 2004 to 2013, it found an antibiotic prescribed at 57.1% of them²¹. Records like those show prescriptions, not whether each one was needed. Why people go anyway came out in a 2018 UK interview study of 39 adults: how they read their symptoms, what they believed a GP or a dentist could do, finding the medical system easier to get into than the dental one, earlier experiences of dental care including anxiety, and whether they were willing and able to pay²².

The emergency department is the right door for toothache only when the NHS's warning signs are there: a swollen area around the eye or neck, or swelling in the mouth or neck that is making breathing, swallowing or speaking difficult¹⁶. Get someone to drive you, or call 999¹⁶.

What about Scotland, Wales and Northern Ireland?

The charges on this page are England's. The other three nations set their own, and this page gives a nation's figure only where an NHS or UK government page it could cite showed one on the day it was written, which for these three was none.

Scotland. Dental charges are set separately by the Scottish Government, and the NHSBSA dental costs page sends readers to NHS inform for them, so check there before you book⁶. A refund of Scottish dental charges uses the Scottish HC5 form, which the NHSBSA says you can download or pick up from a GP practice or pharmacy⁶.

Wales. Charges are set separately by the Welsh Government, and the same NHSBSA page points to GOV.WALES for them⁶. NHS 111 Wales says a Dental Access Portal lets you register interest in a place at an NHS dentist, with health boards allocating routine places through it, and that for an urgent dental problem you should contact the Dental Helpline for the area you are in²³. A Welsh refund uses form HC5W(D), which the NHSBSA says you can request by phone⁶.

Northern Ireland. nidirect lists free Health Service dental treatment among the help open to people entitled because of age, a medical condition or a war pension, and to people who, or whose partner, get Pension Credit Guarantee Credit, or Universal Credit with earnings under set limits²⁴. Others on a low income can claim on form HC1 for an HC2 or HC3 certificate lasting 12 months, and all prescriptions dispensed in Northern Ireland are free for everyone²⁴. nidirect's page on dental charges could not be opened when this page was researched, so no Northern Ireland charge appears here; ask the practice what it will cost when you book.

Frequently asked questions

Can an NHS dentist recommend or prescribe S3?

No NHS dentist can prescribe S3: it is a toothpaste sold from its own website, not a prescription product. A dentist who has examined you can advise on a toothpaste for the cause they find, and can prescribe a high-fluoride toothpaste listed in the British National Formulary for preventing decay¹⁹. None of the NHS pages read for this article names or endorses a toothpaste brand.

Do I have to be registered with a dentist to get NHS care?

No. The NHS says you can contact any NHS dentist and ask for an appointment, whether you have symptoms or need a routine check-up, although you may be put on a waiting list³. A practice may ask you to fill in a registration form at your first visit, and the NHS says that form does not mean you will always get NHS care at that practice³.

Is a scale and polish free on the NHS?

Free outright only if you are exempt from charges. For everyone else, scaling that a dental professional says is clinically needed is NHS care that usually comes inside the Band 1 charge with nothing added, and a hygienist or dental therapist can do it; extensive or complex gum treatment may be charged as Band 2, and scaling that is not clinically needed is paid for privately¹.

Can I get my money back if I was entitled to free treatment?

Yes, if you claim within three months of paying. The NHSBSA refunds NHS dental charges to people who paid and then found they were entitled to free or reduced-cost treatment; in England you apply by email or on form HC5(D) by post, and a Low Income Scheme application can include the refund claim⁶⁵.

What toothpaste do UK dentists recommend for sensitive teeth?

It depends on what is causing the sensitivity, and finding that out is what the examination is for. The guide to what UK dentists recommend for sensitive teeth sets out the ingredients UK sources name and why the advice varies, and the Journal's piece on why teeth suddenly become sensitive explains when a change is a reason to book.
