How Much Does Teeth Whitening Cost in the UK?
Professional teeth whitening in the UK costs roughly £200 to £1,000. Where you land depends on the route you choose. A dentist-supplied take-home kit usually runs £200 to £400, an in-chair session £400 to £700, and premium light-activated systems can reach £1,000.
At Tooth Club, whitening starts from £165, with the final figure depending on the treatment you and your dentist decide is right for your smile.
That range is wide because the term ‘teeth whitening’ covers several different treatments, and the number on the quote reflects what’s involved in each. Here’s how the options break down, what they cost, and why the prices sit where they do.
Teeth whitening costs by treatment type
Whitening prices in the UK depend on the method you choose. Below are the main options you may have available to you:
Whitening option | Typical UK cost | What it involves | Best suited to |
Shop-bought strips and kits | £10-£100 | Daily use over a week or two | Very light surface staining |
Take-home kit from a dentist | £200-£400 | Custom trays and professional gel, worn at home for around two weeks | Most people wanting gradual, even results |
In-clinic whitening | £400-£700 | High-strength gel applied in the chair, often light-activated, in about an hour | Fast results before an event |
Premium light-activated systems | Up to £1,000 | Advanced in-chair systems such as Enlighten | A guaranteed shade and the fastest, most dramatic change |
Top up once you own trays | £30-£80 | Fresh gel in your existing trays | Maintaining a result over time |
Over-the-counter products sit at the bottom of that scale, and UK law limits how effective they’re allowed to be. Professional treatment costs more because it’s more effective.
What the price includes
With a professional treatment, the fee covers:
- A dental assessment to confirm whitening is suitable
- Custom-made trays moulded to your teeth
- Professional-strength gel
- A shade check before and after, so the change is measured
- Aftercare guidance
Once custom trays are made, future top-ups only cost the price of fresh gel.
What comes before the whitening price is any necessary dental work. If there’s untreated decay or gum inflammation, that’s assessed and treated separately before whitening goes ahead, so the gel is applied to healthy teeth and gums.
At Tooth Club, the initial consultation is free, and treatments over £250 can be spread with 0% finance.
What affects the cost of teeth whitening?
Several factors move the price within those ranges, including:
- Treatment type: In-clinic whitening costs more than a take-home kit because it uses an hour of clinical time, a dentist and a surgery. The trade-off is speed.
- The whitening system: Tooth Club dentists use trusted systems including Philips Zoom, Enlighten and Boutique Whitening. Premium systems use advanced formulas and light activation, and cost more than standard trays.
- Clinic location: Practices in London and other major cities charge more than clinics elsewhere in the UK, reflecting higher running costs.
- Dentist experience: A cosmetic dentist with extensive whitening experience may price accordingly.
Teeth whitening costs by region
Where you live affects the price as much as the treatment does, largely because clinic running costs vary across the country. Professional whitening in London typically ranges from £400 to £1,000, in the Midlands from £300 to £700, and across the North of England from £250 to £600.
Tooth Club has clinics across the UK, so you can access the same trusted whitening systems outside the highest-cost city centres. The most reliable figure comes from a local consultation, where the price reflects your teeth and the treatment you choose.
Why professional whitening costs more than a shop-bought kit
In the UK, teeth whitening is legally classified as dentistry, and it can only be carried out by a dentist or a registered dental professional under the Dentists Act 1984. That classification is enforced by the General Dental Council (GDC), and it shapes what you can and can’t buy.
The active ingredient in most whitening products is hydrogen peroxide, and UK law caps its concentration depending on who’s supplying it. Products sold directly to consumers can contain no more than 0.1% hydrogen peroxide. A GDC-registered dentist can legally use up to 6%, around sixty times stronger.
That is the reason a supermarket kit lifts a shade at best, while a professional treatment shifts several. The shop-bought version is legally required to be weak. Anything above 6% is banned outright for cosmetic use, for everyone.
Whitening is for adults only in the UK; it can’t be carried out on under-18s for cosmetic reasons. Beauty salons and mobile providers offering whitening are acting outside the law if they use anything stronger than the consumer limit, regardless of the training they advertise. And because whitening is cosmetic, it isn’t available on the NHS except in rare clinical cases.
Every one of these is a reason the professional price buys something the cheaper alternatives can’t legally match. If you’ve considered a ‘natural’ shortcut, our guide to whether charcoal whitens teeth explains why those fall short, too.
What results can you expect for the cost?
Whitening works on natural teeth by breaking down stains within the enamel. It does not change the colour of crowns, veneers or tooth-coloured fillings, which stay the shade they were made. If you have visible dental work, the usual approach is to whiten first, reach the shade you want, then match any new restorations to it.
Surface stains from coffee, tea, red wine, smoking and everyday food respond well. Deeper, intrinsic discolouration, from certain medications or from within the tooth, is harder to shift and may need more sessions or a different treatment.
Some people notice temporary sensitivity during whitening; for most, it settles within a day or two, and your dentist can tailor the gel and pace to reduce it.
How long do teeth whitening results last?
With good care, professional whitening typically lasts from several months to a few years before you’d want a top-up. Heavy coffee, tea and red wine drinkers, and anyone who smokes, tend towards the shorter end.
To keep results looking their best: brush and floss regularly, limit staining foods and drinks, avoid smoking, and keep up with routine dental visits. Once you own custom trays, maintaining the result is inexpensive.
