We whiten our teeth with our KONZEPT WEISS gel. It contains only natural ingredients and has no adverse effects on dental health. The exact ingredients are: sodium bicarbonate, sodium chlorite, aloe juice, pomegranate seed extract, chamomile flower extract, glycerin, propylene glycol, deionized water, carbomer, xanthan gum, menthol.

Treatment is available with us for anyone aged 16 and over.

No, for ethical reasons, we do not bleach patients who are pregnant, breastfeeding, or undergoing chemotherapy.

The result lasts up to 12 months. However, this depends greatly on daily dental care and consumption of staining foods and beverages, such as coffee or tea, as well as nicotine. For long-lasting results, we recommend visiting one of our stores for an in-person treatment.

Active whitening ingredients in KONZEPT WEISS gel are activated using a cold-light LED lamp, thereby neutralizing organic pigmentation substances in the tooth enamel. The whitening gel and cold LED light neither damage the oral flora nor irritate the gums. The treatment is completely painless and has no side effects.

No, a dental cleaning is not absolutely necessary before the treatment. A dental cleaning primarily cleans the spaces between your teeth. Bleaching, on the other hand, lightens your teeth from the front, so you can also have a dental cleaning afterward without any concerns. However, it makes no difference to the result.

Yes, teeth whitening is especially worthwhile for smokers, as the before-and-after effect is greatest. Over time, nicotine creates deposits on your teeth, which we can completely remove with our treatment.

Basically, we can only whiten natural teeth. However, since deposits also build up over time on bridges, crowns, fillings, and veneers, these can also be lightened to a certain extent. This must then be individually coordinated.

If you’re unable to make it to your appointment, you can reschedule it online or by phone. Cancellations are free of charge up to 24 hours before the appointment; after that, a €50 cancellation fee will be charged.

Your refresh card is valid for 3 months from your treatment date. After 3 months, the card expires and you must book a new treatment at the full price.

No, neither your gem nor your piercing will interfere with the treatment. During the treatment, the lip piercing can be hidden under the lip and will therefore not be an issue. However, if you are considering removing your gem, it is best to do so before the whitening treatment, as otherwise there will be an unwhitened spot beneath the gem.

It depends on which store you would like to visit. It’s best to check which store is near you. You’ll then find information about the payment options on the respective location page.

Numerous treatments have confirmed that our cosmetic teeth-whitening procedure is completely safe and has no side effects. Nevertheless, we advise against treatment during pregnancy and breastfeeding.

We can lighten your teeth by 2–10 shades. It is not possible to predict the exact shade in advance, as it depends on various factors and is partly determined by genetics. The longer the treatment, the more discoloration is removed from your teeth and the lighter they will become.

You don't need to do anything before the treatment. Since the KONZEPT WEISS gel continues to work afterward, you should avoid smoking, eating, and drinking for 2 hours after the treatment. Still water is permitted.

No! Our concept keeps your teeth white continuously. That’s why you receive a REFRESH card after every treatment. With the REFRESH card, the same treatment costs you only €59 within the next 3 months—and that’s forever!

Initially, you can use the kit once a day for 30 minutes until you achieve the desired result. It is best to use the whitening treatment in the evening and avoid tea, coffee, wine, and smoking during the whitening period. At first, we recommend using our PREMIUM WHITENING TOOTHPASTE before whitening. This removes surface deposits and discoloration, allowing the whitening gel to work ideally on the smooth, clean tooth surface.
