In the Diamond Smile BLACK teeth-whitening strips, only medical-grade activated charcoal of the highest quality is used. It is made specifically for teeth whitening and is therefore extra fine. As a result, the fine micro-particles of the activated charcoal reach even the smallest corners between the teeth.
The activated charcoal whitening strips are painless and suitable for both normal and sensitive teeth and gums. You can use the product with confidence to achieve a radiant smile without discomfort.
DiamondSmile is loved by over 575.000 satisfied customers worldwide.
The porous structure of the activated charcoal binds stains, discolouration and bacteria on the tooth surface. This makes the surface of the teeth visibly whiter. The non-slip sealing technology ensures the white strips adhere firmly to the teeth so you can speak or drink with no trouble. They lift off cleanly and easily.
Activated charcoal binds both colourants and odour-causing substances. In this way, stains are removed from the tooth and bad breath is actively tackled. It is particularly effective against stains caused by coffee, tea, tobacco, red wine, soft drinks and antibiotics.
Organic coconut powder: The sponge-like particles reliably remove dyes & stains from tooth enamel.
Coconut oil: The plant fat increases the binding power of activated charcoal.
Bentonite powder: Natural medical product that binds pollutants and bacteria.

Are teeth whitening strips dangerous?
No. The teeth whitening strips are not dangerous, as they are based on natural ingredients and do not attack either the tooth or the gums.
Can I use the teeth whitening strips if I have sensitive teeth?
Yes. Our teeth whitening strips are suitable for all types of teeth. So you can use the strips to whiten your teeth even if you have very sensitive teeth.
How many strips are in the box?
There are a total of 28 teeth whitening strips in a box. Typically, 14 are intended for the lower teeth and 14 for the upper teeth.
How many applications until I see first results?
That always depends on your starting point. As a rule, you’ll see your first successes after 4 applications. By combining with other teeth whitening products such as the teeth whitening kit or activated charcoal, you can enhance and prolong your bleaching effect.
How long does one application with the teeth whitening strips take?
The application time can vary but should be between 10–30 minutes.
Which product goes best with the teeth whitening strips?
The best option is a combination with the teeth whitening kit. After using the strips, you can whiten the teeth again with the lamp to intensify the effect.
What do the teeth whitening strips taste like?
Our teeth whitening strips taste pleasantly of peppermint and leave you with fresh breath.
Why do we work without peroxides?
Peroxides are highly acidic and can attack your teeth, enamel and gums. This usually leads to tooth sensitivity and can cause irritation. For this reason, we do not use peroxides in our products.
