How Much Does Teeth Whitening Cost In The UK?

In the UK, teeth whitening at a dentist is private treatment and each practice sets its own price, so there is no single national figure. Bupa Dental Care, whose practices offer whitening, is one named source that publishes ranges. Its teeth whitening page, read on 4 November 2026, says "prices for at-home whitening typically range between £360 and £620, and in-practice whitening costs range from £615 to £965", and puts an asterisk on those figures: "A consultation will be required to confirm suitability and determine an exact price before treatment." Whitening is not available on the NHS. Below: what those ranges include and leave out, what you are paying a dentist for, the UK rules that separate a dentist's whitening from a product you buy yourself, and the ongoing cost of keeping a result.

Is teeth whitening free on the NHS?

No. The NHS page on teeth whitening says: "Teeth whitening is not available on the NHS. You have to pay for it as a private patient at a dental surgery." Bupa gives the reason: "Teeth whitening is a cosmetic procedure, which means it improves your appearance but isn't medically necessary, so it's not covered by the NHS."

So the price you are quoted is a private fee, set by the practice, and, as Bupa's own footnote below says, prices may differ between practices.

What Bupa's published ranges include, and what the asterisk says

Bupa's figures are the only named price ranges in this guide, and they come with conditions that matter as much as the numbers. The page says the cost "will vary depending on whether you choose at-home or in-practice whitening", and that "How much teeth whitening costs can depend on things like where you live, which practice you go to, and whether you opt to have treatment at your dental practice or at home."

The asterisk on the ranges leads to a footnote further down the page. On price, it says:

• "A consultation will be required to confirm suitability and determine an exact price before treatment."
• "Prices quoted apply to standard whitening treatments only; complex cases or additional procedures may incur extra costs."
• "The stated price ranges exclude any optional add-ons or follow-up treatments."
• "Prices may differ by location and individual practice policies."

Two points follow from that wording. First, the ranges are a starting point, not a quote: the page itself says "an in-person consultation is required to determine the exact cost". Second, anything beyond the standard treatment, including follow-up treatment, sits outside the range. The page also says "Your dentist can explain the full cost, and you might be able to spread your payments out."

A note on what "at-home" means in Bupa's figures. It is not a product from a shop. It is a dentist's kit: "custom-made trays that look like a retainer, and a whitening gel that you place on the inside."

The three routes, and the UK rules that separate them

Whitening in the UK splits into three routes, and the law is what draws the lines between them. For the wider picture of every option side by side, see your teeth whitening options. This section is about how each route is priced and regulated.

1. In-chair whitening at a dental practice

Bupa describes this as your dentist using "a strong bleaching agent and a special light to whiten your teeth in the dental surgery." It says the gel goes on "for 15 minutes at a time", four times, and that the appointment "could take anything up to 2.5 hours". It adds that in-practice whitening "can often be done in a single appointment, so it's faster than whitening your teeth at home, but may also cost more." That matches the order of its two ranges, with in-practice the higher of the two.

2. Take-home trays from a dentist

Here the dentist makes trays to fit your teeth and gives you a gel to use at home. The NHS says a dentist "can prescribe a kit which contains a whitening gel and small trays which are made to closely fit around your teeth, like a mouthguard", and that you then wear the trays "for around 2 to 6 weeks to gradually whiten your teeth." Bupa says it "can take up to 6 weeks". For a worked example of one dentist take-home system, our explainer on how Boutique Whitening works walks through the appointments, trays and gels step by step.

3. Products you buy and use yourself

Strips, home kits, pens and toothpastes sold to the public are cosmetics, priced by whoever sells them, and they sit under a different rule. Bupa puts it plainly: "In the UK, shop-bought whitening kits are legally only allowed to contain 0.1% hydrogen peroxide." The legal text is Annex III, entry 12 of the cosmetic products regulation as it applies in Great Britain. It allows no more than 0.1% hydrogen peroxide, "present or released", in oral products including "tooth whitening or bleaching products". Products above 0.1% and up to 6% are "To be only sold to dental practitioners. For each cycle of use, the first use to be only done by dental practitioners or under their direct supervision if an equivalent level of safety is ensured. Afterwards to be provided to the consumer to complete the cycle of use." They are "Not to be used on a person under 18 years of age."

Because the rule counts hydrogen peroxide "present or released", carbamide peroxide is caught by it too. That legal line is what separates a gel supplied through a dentist from a product sold over the counter.

What you are paying a dentist for

The sources describe several steps before and during a dentist's whitening. Bupa says the exact price is set at a consultation, so ask which of these your quote covers.

• An assessment first. The General Dental Council (GDC), the UK dental regulator, says tooth whitening "should only be undertaken following a proper assessment by a registered dentist and on their prescription." Bupa says "Your dentist will do a thorough examination to make sure your teeth and gums are healthy enough for whitening treatment", and that they will "go through your treatment options, the shade you want and any costs with you."
• Impressions and trays. Bupa says that if you go ahead, "your dentist will take impressions of your teeth to create your custom-made trays."
• A fitting appointment. The NHS says "You'll usually have an appointment to check the trays fit your teeth well, explain how often to wear them, and be shown how to protect your gums during the treatment."
• Protection in the chair. For in-practice whitening, Bupa says the dentist will start "by placing a shield over your gums to protect them."

The GDC also says your dentist can "examine you, assess whether this is the best treatment option for you and outline the costs and risks of the treatment, so that you are properly informed about it." That consultation is the place to ask exactly what your quote covers, and what it does not.

Who is allowed to whiten your teeth

Whitening from anyone outside the registered dental team is not a cheaper alternative: under UK rules it is not a legal one. The GDC says that once a dentist has prescribed whitening, "they will either carry it out themselves, or a registered dental hygienist, dental therapist or clinical dental technician can provide the treatment on the dentist's prescription." It goes on: "No other types of dental professional can safely offer this treatment and anyone who is not on our register will be breaking the law if they do so." You can check someone on the GDC register before you book. The detail behind this, and what you can legally buy, is in the UK whitening rules in full.

Top-ups: the cost after the first course

A whitening result fades with time, so it is worth pricing what comes after the first course. For whitening from a dentist, the NHS says "Teeth whitening is not permanent, but if you follow your dentist's advice the effect may last for around 3 years." Bupa says professional whitening "can last for a few years, especially if you take good care of your teeth", and that "You can also top-up your whiter smile at home using the kit your dentist gave you." After in-practice whitening, it says, "Your dentist may also give you a top-up kit to take home, which you'll need to use for about a week."

Remember the footnote: Bupa's ranges "exclude any optional add-ons or follow-up treatments". So when you compare quotes, it is worth asking whether top-up gel, replacement trays or a review appointment are included, or charged separately. What shortens or lengthens a result is covered in how long teeth whitening lasts.

On the home route, top-ups are part of the plan from the start. Our strips are topped up with 2 to 3 strips a week once the 14-day course is done, and two people whitening together, or anyone planning top-ups, can order the 56 strip bundle saver, which is two boxes in one order.

Where Pure Glow sits if you choose the home route

If you decide the dentist route is not for you, the home route means a product you buy and use yourself, under cosmetics law. Pure Glow makes PAP whitening strips, and the active ingredient is PAP, short for phthalimidoperoxycaproic acid. The ingredients in our box contain no hydrogen or carbamide peroxide.

PAP lifts surface stain and works on the coloured compounds inside the tooth, by a gentler route than peroxide takes. Our explainer on how PAP whitening works goes through the chemistry, and there is a separate page on peroxide-free teeth whitening for anyone whose main reason for avoiding the shop shelf is peroxide.

What our strips are built to give you:

• Zero sensitivity. Clinically tested, with zero sensitivity, and dentist approved.
• Up to 6 shades whiter in 14 days, depending on where you start. One strip a day, worn for a minimum of 30 minutes.
• Enamel safe, with hydroxyapatite that supports the enamel surface, and xylitol in the formula.
• A no-slip grip that keeps the strip where you put it, and clean removal.
• The 14-Day Two-Shade Guarantee: if you're not at least two shades whiter, you may be eligible for a full refund under the guarantee terms.

The live prices are on the cards on this page. How the price of a box of strips is built up, and how to compare it fairly, is in what goes into strip prices.

A cost the price tag does not show

The holiday that started Pure Glow is a cost story too. In Ibiza I used three sets of strips and none of them stuck: roughly £5 straight in the bin by the pool. Peroxide strips gave me bad sensitivity and made my teeth feel brittle. Non-peroxide ones would not stick, slid around, gave patchy results and left gunk behind.

Back home I bought every whitening strip I could get and catalogued every fault. It took ten months of testing, and four formulas rejected, before the one we use now. A box you throw away is money gone, whatever it cost. So whatever route you choose, price the whole course, including what happens if it does not stay on or you cannot finish it.

Is it worth paying a dentist?

That depends on what you want from the result, how quickly, and what you are prepared to pay, and it is a separate question from what whitening costs. We weigh the two routes against each other in is teeth whitening worth it. If you have dental work at the front, gum problems or any concern about your dental health, speak to your dentist before you start, whichever route you take. Our strips are not suitable for children under 12, and the box says not to use them with gum disease, ulcers, exposed gums or recent oral surgery.

Frequently asked questions

How much do dentists charge to whiten teeth in the UK?
Each practice sets its own fee. Bupa Dental Care's teeth whitening page gives "between £360 and £620" for at-home whitening with a dentist's trays and "from £615 to £965" in practice, for standard treatments only, with the exact price set at a consultation. Ask the practice what its quote includes.

Is teeth whitening available on the NHS?
No. The NHS says you have to pay for it as a private patient at a dental surgery. Bupa explains that it is a cosmetic procedure that "isn't medically necessary".

Is in-practice whitening dearer than trays?
On Bupa's ranges, yes. Its own wording is that in-practice whitening is faster, because it "can often be done in a single appointment", "but may also cost more." The ranges on its page follow that order.

Can a beautician whiten my teeth for less?
Not legally. The GDC says only a dentist, or a registered dental hygienist, dental therapist or clinical dental technician working on a dentist's prescription, can provide tooth whitening, and anyone not on its register who does so is breaking the law.

Will I need to pay again later?
Whitening is not permanent, so plan for it. For dentist whitening the NHS says the effect may last for around 3 years if you follow your dentist's advice, and Bupa's ranges exclude follow-up treatments. With our strips, top-ups are 2 to 3 strips a week after the 14-day course.
