The examination
The one fixed extra. UK regulations require a dentist to examine you before supplying peroxide gel above shop strength, so every whitening patient pays for a check-up. Existing patients with a recent examination do not need another.

Teeth whitening cost in London: the £399 fee and what sits around it
Dentist-prescribed home whitening at Wimpole Street costs £399. That fee covers custom trays for both arches, enough gel for a full two-week course, the fitting appointment and the review. What it does not include, and what the law requires, is the dental examination beforehand, charged at £30 for new patients. This page sets out the whole picture: the price list, the small number of things that change it, what is bundled and what is separate, the longer-term cost of keeping teeth light, and how the fee sits against the spread of whitening prices across London, from supermarket strips to lamp treatments on the medical streets of W1.
Typical range
£399 + £30 examination

Variables
What changes the price
Surface stain
Heavy tea, coffee or tobacco staining sits on the enamel rather than in it. A hygiene visit before whitening clears it so the gel works on the tooth itself; skipping it can mean a patchier result.
Starting shade and cause
Yellow teeth respond well to a standard course. Grey or banded teeth may need a longer course, more gel or, honestly, a different treatment. We tell you which at the examination.
Restorations that will not lighten
Fillings, crowns and old bonding on front teeth keep their colour. If they will look darker afterwards they may need replacing, which is a separate fee and a separate decision.
Maintenance habits
The upfront fee is the same for everyone; what varies is how much top-up gel you buy over the years. Coffee drinkers and smokers top up more often.

Paying
Spreading the cost
At £399 most patients pay on the day the trays are fitted. Interest-free instalments over up to twelve months are available for whitening when it forms part of a larger cosmetic plan above the minimum finance value, subject to status.
Finance is subject to status and terms apply. Medical and Dental Limited is a credit broker, not a lender. Terms are confirmed in writing before you sign.
Context
How we compare
Whitening prices in London span an enormous range because the products differ so much. Shop-bought strips and pens at £20 to £50 are limited by law to 0.1% hydrogen peroxide and do little beyond removing surface stain. Beauty-salon lamp treatments at £100 to £300 cannot legally use dentist-strength gel either, and much of their immediate effect is dehydration that reverses in days. Dentist-supervised home whitening in London is commonly £300 to £600, and in-chair lamp treatments at dental practices often £500 to £800 or more, with W1 clinics towards the top.
Our £399 fee sits in the lower half of the dentist-supervised range and is the same at all three Medical & Dental clinics. We do not offer lamp whitening because, in our reading of the evidence, slow home whitening in custom trays produces an equal or better result that is easier to maintain, at a lower fee.
FAQ
Questions about cost
For the whitening, yes: trays, gel, fitting and review. New patients also pay £30 for the examination that the law requires first. If you want a hygiene visit beforehand, that is from £95 and optional.
Because it is a separate clinical service that some patients have already had. Bundling it would mean existing patients paying twice. New patients pay the introductory £30 rather than the usual £95.
It contains up to 0.1% hydrogen peroxide, sixty times weaker than the gel a dentist can prescribe. It costs less because it does less. Most people who try shop kits first end up whitening properly afterwards, having paid twice.
In our view, no. The lamp accelerates the gel slightly but also dehydrates the teeth, which makes them look lighter for a few days before the colour settles back. Custom trays at home give a result that holds, for less money.
A syringe of top-up gel from £30 lasts several maintenance sessions. Most patients spend £30 to £60 a year; heavy coffee drinkers a little more. The trays last years if looked after.
No. We offer one method because we think it is the right one. A hygiene visit alone from £95 removes surface stain and can be enough for some people, and we will say so if that applies to you.
Yes. £399 applies now at South Kensington and St Paul’s and at Wimpole Street from 1 October 2026.
