Teeth whitening kit

A teeth whitening kit from our London dental team includes custom-made trays and a professional-grade whitening gel.

The trays are designed to fit your teeth perfectly, ensuring even application of the whitening gel, which is more effective than over-the-counter options.

Typically, the kit also includes instructions on how often 
and for how long to wear the trays.

This professional at-home teeth whitening option offers clinically proven results and is one of the safest ways to whiten your teeth in London.

Teeth whitening gel

Teeth whitening gel is a bleaching product used to lighten the colour of teeth by breaking down stains on the enamel.

It typically contains active ingredients like hydrogen peroxide or carbamide peroxide, which penetrate the surface of the teeth to whiten them over time.

The gel is applied using custom-made trays provided by your dentist, ensuring an even and effective treatment.

Our professional teeth whitening gels offer faster and more noticeable results than shop-bought products and are fully approved for safe use in the UK, making them ideal for patients looking for predictable teeth whitening results in London.

How does teeth whitening work?

Teeth whitening gel works by using special ingredients, like hydrogen peroxide, to lift stains from your teeth.

When you apply the gel, it releases tiny oxygen molecules that seep into the surface of your teeth.

These molecules break apart the particles that cause discolouration, effectively “bleaching” the stains away.

This process helps your teeth look whiter and brighter by removing the unwanted colour from inside the tooth itself.

Teeth whitening strips

Teeth whitening strips are thin, flexible strips coated with a whitening gel that contains bleaching agents like hydrogen peroxide or carbamide peroxide.

While they offer a convenient way to brighten your smile at home, they may not deliver results as effective as professional teeth whitening treatments performed by a dentist.

Ultimately, the limitations of teeth whitening strips can leave users feeling disappointed, as they often fail to meet expectations and may even result in uneven whitening or sensitivity issues.

Whitening has three major benefits

Boosted Confidence in Your Smile

A bright, white smile is often the first thing people notice. Professional whitening removes stains caused by coffee, tea, wine, and smoking, restoring teeth to their natural, brighter shade. Patients feel more confident in meetings, photos, and everyday social interactions.

A Younger, Healthier Appearance

As we age, enamel naturally darkens and yellows. Whitening visually "rejuvenates" the smile, giving the face a fresher, more polished look — often the first change people notice after treatment.

Safe, Professionally Supervised Results

Unlike at-home kits, in-office whitening at a clinic is tailored to each patient's enamel and gum condition, reducing the risk of sensitivity or damage. The dentist customizes gel concentration and application time to deliver optimal results without compromising tooth health.

Frequently asked questions

How can I whiten my teeth?

You can whiten your teeth through professional treatments or at-home methods. Professional whitening is done by a dentist using stronger whitening agents, while at-home options include whitening toothpaste, strips, or trays. Each method can brighten your smile but varies in strength and results. Professional whitening done by a dentist usually leads to better results as the strength of the whitening legally allowed with non dentist / at home treatments is much lower.

Whitening is included with every Invisalign package, and it’s the first step before composite bonding, so your bonding can be matched to your new, brighter shade.

Where can I get teeth whitening in London?

You can get professional teeth whitening in London at any of our Rüh Dental clinics. We offer safe, effective whitening treatments at our Harrods, Fleet Street and Notting Hill Gate clinics, providing both in-clinic and dentist-supervised at-home options. Whether you’re looking for quick in-chair whitening or a customised whitening kit, our London clinics offer predictable results under expert care.

How does teeth whitening work?

Teeth whitening works by using bleaching agents like hydrogen peroxide or carbamide peroxide to break down stains on your teeth. These chemicals penetrate the enamel to lighten the colour of the tooth, leaving you with a brighter and whiter smile.

How long does teeth whitening last?

Professional teeth whitening can last between 6 months to 2 years, depending on your habits. Certain habits like smoking or consumption of stain-causing foods and drinks (like coffee or red wine), can make results fade faster. Regular maintenance, such as top-ups, helps extend the results for a longer period of time.

How long does teeth whitening take?

Professional whitening treatments usually take about 1-2 hours in the dentist’s chair. For at-home whitening kits, it can take several days or weeks, depending on the strength of the product and how often you use it, you can also stop using it once you are happy with the results.

How can I whiten my teeth naturally?

Natural methods include brushing with baking soda and oil pulling. However, these methods are far less effective than professional treatments and should be used with caution. We always advise consulting a professional at one of our London clinics when considering tooth whitening.
