Our purple teeth-whitening gel is designed to remove everyday discolouration from your teeth. This special stain-removal formula works thanks to its ingredients and violet colour. Because yellow and violet are complementary colours, the violet neutralises yellowish pigments and effectively lifts them from the teeth. At the same time, the serum helps protect against future yellow pigments. With regular use, you can build increasing protection against stains.
DiamondSmile delights over 575.000+ satisfied customers worldwide.
The advanced formula penetrates deep into the enamel to tackle stubborn discolouration and whiten your teeth. Unlike conventional products, our whitening gel offers an effective way to take your smile to the next level.
Apply the gel evenly to your teeth and let it do the work. The fast results will impress you, and you’ll soon enjoy a radiant smile.

What do I need the refill gel for?
You need the refill gel when the teeth-whitening gel in your bleaching kit is empty. It’s always a good idea to purchase a refill set along with the bleaching kit to carry out a longer and more sustainable whitening regimen.
How does the at-home teeth-whitening set work?
Discoloration and stains on the tooth are removed naturally through oxidation on the enamel, and the tooth is lightened.
How can the bleaching effect be improved?
Improve and prolong the bleaching effect with our activated charcoal. Using it before bleaching makes the teeth even brighter, as the activated charcoal can already remove coarse discoloration.
How many applications does the gel provide?
Per gel syringe, 3–4 applications can be carried out. We always recommend buying a refill gel with the teeth-whitening set. This allows for long-term treatment.
How long do teeth stay white after use?
The whitening effect of the bleaching set usually lasts 1 to 2 years. After use, you should continue to take good care of your teeth.
Is the bleaching set safe?
The DiamondSmile bleaching set has been approved, tested and certified in Germany (certificates: CE, FDA, ISO, MSDS). We also recommend visiting your dentist for a professional dental cleaning and to get advice on whether your teeth are suitable for a home bleaching set.
Is teeth whitening at the dentist better?
Dentists usually use the active ingredient hydrogen peroxide or carbamide peroxide. Both can strongly affect tooth enamel and gums and cause pain.
Will the bleaching set even work for me?
The active ingredients in our gel in the bleaching set are designed to act directly on the tooth regardless of the condition of the teeth.
Why do we work without peroxides?
Peroxides are highly acidic and attack your teeth, enamel and gums. This usually leads to hypersensitivity of your teeth and can cause irritation. For this reason, we do not use peroxides in our products.
