Is teeth whitening at the dentist better?
Both at-home whitening kits and expensive in-office whitening can deliver similar results. The effectiveness of teeth whitening with glycerin mainly depends on two factors: the concentration of glycerin and the time the active ingredient remains in contact with the teeth. DiamondSmile uses the maximum amount of glycerin permitted in Germany in the Teeth Whitening Set to whiten teeth.
Dentists often use the active ingredient hydrogen peroxide or carbamide peroxide. Both can severely attack the enamel and gums and cause pain.
How long do teeth stay white after use?
The whitening effect of the kit usually lasts 1 to 2 years. After the application, you should continue to care for your teeth. It’s also advisable to limit staining foods such as coffee and tea. Smoking should also be avoided to ensure long-lasting results. If the effect fades, you can always get a new whitening gel for your kit from us.
How does the at-home whitening kit work?
To whiten teeth, the active ingredient glycerin reaches the enamel through power LED activation technology. The oxygen molecules of the whitening agent touch the discolored molecules in the tooth, causing them to dissolve and revealing the tooth’s natural white color.
Enhance and prolong the whitening effect with our activated charcoal. When used before whitening, teeth become even brighter because activated charcoal can remove heavier discoloration. In addition, the whitening effect is prolonged with weekly use of activated charcoal.
Is the whitening kit safe?
The DiamondSmile whitening set has been approved, tested, and certified in Germany (certificates: CE, FDA, ISO, MSDS). The concentration of the active ingredient glycerin has been chosen so you can expect a maximum whitening effect without endangering your tooth enamel. For optimal use, we recommend following the instructions in the whitening kit. It is also advisable to visit your dentist for a professional dental cleaning and to advise you whether your teeth are suitable for an at-home whitening kit.
How is the kit applied?
To use the whitening kit in the best possible way, please follow these instructions:
1. Brush your teeth thoroughly with toothpaste.
2. Remove the thin plastic tab located between the batteries.
3. Attach the mouthpiece to the LED light.
4. Spread 1/4 of the gel on the upper part and 1/4 on the lower part of the mouthpiece.
5. Put it in your mouth and turn on the light.
6. Wait 10 to 20 minutes before turning the light off.
7. Rinse your mouth with warm water.
8. Smile!
Are batteries included with the light?
The LED power-on light uses button batteries (CR2450), which are included. For safety reasons, we had to place a thin plastic tab between the battery and the button to break the contact.
Why do we work without peroxides?
Peroxides are very acidic and will attack the teeth, enamel, and gums. This generally makes your teeth become hypersensitive and can cause irritation. For this reason, we do not use peroxides in our products.
How does the teeth whitening set work?
Our teeth whitening kit uses a professional formula and advanced technology to remove stains from teeth. It consists of a special whitening gel and an LED light that helps activate the gel. The combination of gel and light effectively whitens the teeth.
Is the teeth whitening set safe for my teeth?
Yes, the teeth whitening kit is safe for your teeth when used as directed. The special formula is gentle on teeth and enamel while effectively removing stains. However, it’s important to follow the recommended application time and frequency to achieve the best results and protect the health of your teeth.
Can I use the teeth whitening set on sensitive teeth?
Yes, the teeth whitening set is also suitable for sensitive teeth. The formula is designed to provide gentle whitening and minimize discomfort or sensitivity. However, if you suffer from severe sensitivities, we recommend consulting your dentist before use.

The heart of the whitening kit is the Power-LED, delivering maximum whitening performance with 16 LED lights.
