How much does teeth whitening cost in the UK? (2026 price guide)
Professional teeth whitening in the UK typically costs £300–£700, with take-home dentist kits a bit cheaper and in-chair “power” whitening at the top end. The big things that change the price are the method, the clinic and your city — here’s the full breakdown, plus what’s actually safe and legal.
First, the current national picture from clinics on TreatmentCosts:
So, what does teeth whitening cost?
For professional whitening at a dentist, most UK clinics charge £300–£700. Take-home kits with custom trays tend to sit at the lower end; in-chair laser/light whitening (done in a single visit) sits higher. A combined approach — in-chair plus take-home top-ups — costs the most but gives the most dramatic, longer-lasting result.
One thing to know upfront: the cheap “whitening” you see in shops or salons is a different thing entirely (more on that below). For real, safe results you’re paying a dentist.
The main types — and what they cost
- Take-home kits (from a dentist): custom-made trays + professional gel, ~£200–£400. You whiten gradually at home over a couple of weeks.
- In-chair / “power” whitening: done in the dental chair in about an hour, ~£350–£700. Fastest results.
- Combined: in-chair kick-start plus take-home trays, ~£400–£800. Best for stubborn staining.
Prefer to do it gradually at home? Here’s the current price for dentist take-home kits:
What you’re paying for
- A dental check first — whitening only works well (and safely) on healthy teeth and gums.
- Custom-fitted trays (for take-home) or the in-chair procedure.
- Professional-strength gel you can’t legally buy over the counter.
- A dentist supervising the result.
What changes the price
- Method — take-home vs in-chair vs combined.
- How stained your teeth are (more sessions/gel = more cost).
- City and clinic — central London skews higher.
- Brand of whitening system used.

Is cheap whitening safe? (important)
This is where price and safety collide. In the UK, tooth whitening can only legally be carried out by a registered dental professional. Beauty salons or non-dentists offering whitening are breaking the law — and using the wrong strength of product can damage your gums and enamel. Over-the-counter “whitening” kits are limited to a tiny amount of active ingredient, so they do very little.
So if a deal looks too cheap to be true, it usually is. Paying a dentist isn’t just about a brighter smile — it’s about doing it safely. The good news: comparing dentists means you can find a safe, professional price that suits your budget.
How long does it last — is it worth it?
Professional whitening usually lasts 1–3 years, depending on your diet (coffee, tea, red wine and smoking all dull it faster). Many people keep trays for occasional top-ups, which makes the upfront cost go further. Compared with permanent options, whitening is the cheapest way to brighten your smile.
Whitening vs bonding vs veneers
Whitening only changes the colour of your natural teeth. If you also want to fix chips, gaps or shape, you’re looking at:
- Composite bonding — tooth-coloured resin to reshape teeth (mid-range cost).
- Porcelain veneers — thin custom shells for a full smile makeover (the priciest option).
A common, budget-friendly combo is to whiten first, then bond — so the bonding is matched to your brighter shade.
How to avoid overpaying
- Make sure it’s a registered dentist — never a salon.
- Ask what’s included — check-up, trays, gel, top-ups.
- Consider a take-home kit if you want results on a budget.
- Compare a few clinics — whitening prices vary a lot.
- Whiten before any bonding or veneers, so the colour is matched once.
Teeth whitening cost FAQs
How much does professional teeth whitening cost in the UK?
Usually £300–£700 at a dentist — take-home kits are cheaper, in-chair whitening costs more, and a combined approach is the most expensive.
Why is salon or shop whitening so much cheaper?
Because it isn’t the same thing. Only registered dental professionals can legally whiten teeth in the UK, and over-the-counter kits are too weak to do much. Cheap “whitening” can also be unsafe.
How long does teeth whitening last?
Typically 1–3 years, depending on diet and lifestyle. Take-home trays make occasional top-ups easy.
Does whitening work on crowns or veneers?
No — whitening only lightens natural teeth. If you have crowns, veneers or bonding, those won’t change colour.
Is take-home or in-chair whitening better value?
Take-home kits are usually cheaper and very effective over a couple of weeks; in-chair is faster but costs more. Many people combine both.
