Professional Tooth Whitening in London, Without the Guesswork
Behrens Dental Practice offers professional teeth whitening in London at our practice in South Kensington, with in-chair whitening and custom-fitted home whitening trays. Every treatment is supervised by a dentist and starts with a check of your oral health.
With so many shop-bought kits and online offers, it can be hard to know what is safe and what will actually work. We look at the shade and condition of your teeth, explain honestly what whitening can achieve for you, and recommend the method that suits your teeth and your diary.

Why Choose Behrens: Whitening Led by Dentists
At our practice, teeth whitening is a dental treatment, planned and supervised by our clinical team from start to finish.
Led by Experienced Dentists
Whitening is carried out under the guidance of Dr. Ole Behrens, principal dentist with a special interest in gum treatment and implant surgery, and Dr. Chiara Burgio, whose work focuses on aesthetic dentistry and smile design. Every patient starts with an assessment of whether whitening is right for them.
Made to Fit, Not One Size Fits All
Our take-home trays are custom-made for your mouth. That keeps the gel even and away from your gums, and helps avoid the gum irritation that is common with shop-bought kits.
A Plan That Fits Your Life
We talk through your goals, your lifestyle and your dental health, then recommend a quick in-chair treatment or a gradual approach at home.
A Focus on Safety
Every treatment follows strict clinical protocols and uses regulated, professional-grade whitening materials.
In-Chair or Home Whitening: Choosing the Right Option for You
We offer two professional whitening methods. Which one suits you depends on how quickly you'd like results and whether you'd rather whiten at the practice or at home.
In-Chair Whitening
For a faster result, in-chair whitening can lift your teeth by several shades in a single visit of about two hours. We apply a concentrated whitening gel and activate it with a special light, using Zoom whitening here at the practice. It suits busy diaries and anyone whitening before a special event.
Professional Home Whitening Kits
For a gradual, controlled result, we make custom trays from a precise digital scan of your teeth. You wear them daily with professional-strength gel and usually reach the shade you want in about two to three weeks.
What Decides the Cost of Whitening?
The cost of professional teeth whitening in London depends mainly on the method: take-home trays you wear with a whitening gel, or a single whitening visit at the practice. After checking your teeth, we'll recommend a method and confirm your cost before any treatment starts.
- Take-home whitening with custom trays: the treatment covers trays made to fit your teeth and the whitening gel you use with them. You whiten gradually at home, usually over two to three weeks.
- In-chair whitening: the treatment is one visit at the practice, of about two hours.
The Science Behind a Brighter Smile
Teeth become discoloured in two ways, and professional whitening is designed to tackle both.
Extrinsic Stains
Stains on the surface of your enamel, caused by coffee, tea, red wine and smoking. These are the easiest to remove.
Intrinsic Stains
Discolouration inside the tooth, often caused by ageing, an injury or certain medications. These need professional-grade whitening agents that work below the surface.
Gentle on Enamel, Tough on Stains
Our treatments use hydrogen peroxide or carbamide peroxide, which break apart the pigments that cause staining and reveal a brighter tooth without damaging it. Not every stain responds in the same way, which is why we assess your teeth before we recommend a method.
What Patients Ask Before Whitening
Is teeth whitening safe?
Yes. Teeth whitening is very safe when it is carried out by a qualified dental professional. Before any whitening, we give you a full oral health check, because underlying problems such as plaque build-up, which can look like dark lines on the teeth, should be treated first. Then we recommend the method that suits you.
Does teeth whitening hurt?
Most patients find teeth whitening comfortable. Some feel temporary sensitivity during or after treatment, and we take precautions to keep it to a minimum. Any sensitivity usually settles within 24 to 48 hours. If your teeth are often sensitive already, mention it at your assessment and we will take it into account when we plan your whitening.
How long do teeth whitening results last?
With good oral hygiene, and by cutting down on the foods and drinks that stain, professional whitening results can last for several years. How long yours last depends partly on your habits. We can also provide top-up gel to use at home with your trays, which helps keep your smile bright between visits.
Does whitening work on crowns or veneers?
No. Whitening gel doesn't change the colour of crowns, bridges, veneers or other artificial restorations. If you're planning cosmetic work, it's best to whiten your natural teeth first, so any new restoration can be matched to your brighter shade. If you already have crowns or veneers, we can talk through your options at your assessment.
Where can I get teeth whitening in South Kensington?
Behrens Dental Practice offers teeth whitening in South Kensington at 21 Thurloe Place, London SW7 2SP, a few minutes' walk from South Kensington station. We're open until 8pm Tuesday to Thursday and on Saturdays, so your whitening assessment and appointments can fit around work. You can book online or call the practice.
Can I get teeth whitening on the NHS?
No. Teeth whitening is not available on the NHS, so it is always arranged as private treatment. As a private practice, we'll explain at your assessment which whitening option suits your teeth, and you'll know the full cost before treatment begins. We offer both in-chair whitening and take-home trays, and we can talk you through each one.
