Is teeth whitening better at the dentist?

Home whitening kits as well as the expensive dentist whitening can lead to similar results. The effectiveness of glycerin-based tooth whitening depends primarily on two factors: The concentration of glycerin and the time the active ingredient is in contact with the teeth. DiamondSmile uses the maximum amount of glycerin allowed in Germany in the Teeth Whitening Bleaching Set to whiten the teeth. 

Dentists usually 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 application?

The whitening effect from the whitening kit usually lasts for 1 to 2 years. After the application you should continue to take good care of your teeth. It is also advisable to limit discolouring foods such as coffee and tea. Also, smoking should be avoided to guarantee lasting results. If the effect fades, you can always get new whitening gel for your whitening kit from us.

How does the home teeth whitening kit work?.

To whiten teeth, the active ingredient glycerin is used, which reaches the enamel through the power LED activation technology. The oxygen molecules of the bleaching agent touch the discoloured molecules on the tooth, causing them to dissolve and revealing the natural white colour of the tooth.

Improve and prolong the bleaching effect with our activated charcoal. By using it before bleaching, the teeth become even brighter, as the activated charcoal can already remove coarse discolourations. In addition, the bleaching effect is prolonged by weekly use of activated carbon.

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 was chosen so that you can expect a maximum whitening effect without endangering your tooth enamel. For the best possible application, we recommend that you follow the instructions in the whitening kit. It is also advisable to visit your dentist for a professional teeth clean and advice on whether your teeth are suitable for a home bleaching set.

How do I apply the set?

To best apply the whitening kit, you should follow these instructions: 


1. Carefully brush teeth with toothpaste 

2. Remove the thin plastic disc between the batteries 

3. Attach the mouthpiece to the LED light 

4. Spread 1/4 of the gel on the top and 1/4 on the bottom of the mouthpiece 

5. Put it in your mouth and turn on the light 

6. Wait 10 to 20 minutes before turning off the light 

7. Rinse mouth with warm water 

8. Smile! 

Are batteries included with the light?

The power LED light uses button cells (CR2450), which are supplied directly. For safety reasons, we had to put a thin plastic washer between the battery and the button to break the contact.

Is the whitening kit better than whitening strips?

The results of our customers are usually much better with the whitening set than with conventional whitening strips. One reason for this is the built-in power LED activation technology, which activates the glycerin directly on the tooth. This means that even stubborn colour particles can be split and thus made invisible.
