What is the difference between Whitening System and Teeth Whitening Pen?

Whitening System is more efficient because of the mouth trays that makes the bleaching process more efficient.

The Teeth Whitening Pen is great to carry with you on a trip or to work. It has the same gentle formula as the Whitening System and is perfect for spot treatments.

For maximum effect, we recommend that you treat both with mouth trays and the pen. Whitening System can be performed in the evening and Teeth Whitening Pen in the morning and/or during the day.

The pen's content is sufficient for about 20 treatments.

How does Whitening System work?

Whitening System uses a mouth tray and gel is a form of bleaching known as the oxidation method. The oxidizing agent in the gel releases solitary oxygen atoms, free radicals, which then break down the organic molecules (discolouration).

It usually takes 2-3 days to see the first results, but we recommend you use it for 3-7 consecutive days. The usage depends on the amount of discoloration you wish to remove.

Use ¼ ml to ½ ml of gel on each mould. Place a thin layer of gel in the front portion of the mould, so that the gel covers the outside of your teeth. If you add too much gel into the mould, it might get squeezed out by your teeth and end up on your gums.

Detailed instructions with pictures are available in the packaging, as well as on the product page.

Does Whitening System entail any harmful substances?

No, our teeth whitening is specially developed by dentists to be safe and comfortable, and to give good results. Our method is exactly the same as the one used by dentists, and no studies indicate it is harmful.

Some persons with sensitive gums can experience some irritation. To avoid this, wipe away any excess gel from your gums, alternatively you can rub some Vaseline on your gums before each treatment.

The enamel is completely unaffected by Whitening System. The free radicals only affect organic matter and therefore the enamel remains completely unaffected.

Can I use Whitening System whilst pregnant or breastfeeding?

There is no known reason why it would be harmful, but we recommend that you wait until you are no longer pregnant or breastfeeding before whitening your teeth. You should also avoid whitening your teeth if you have braces, poor gums or tooth decay. Consult your dentist if you are not sure whether you have any of the aforementioned issues.  

Can I whiten my teeth even if I have false teeth made of plastic or porcelain?

Yes, it is possible to whiten your teeth even if you have teeth made of plastic or porcelain. Keep in mind that it is not possible to make false teeth any whiter than they were initially. The discolourations will be removed even on false teeth and they will revert back to their original colour.

You can use Whitening System with tooth jewellery.

I already have mouth trays. Can I buy the Whitening System gel separately?

Yes you can. The refill set is called Whitening System (Refill).

Does Swiss Clinic use the same teeth whitening as dentists?

Yes, we sell exactly the same product as dentists. You can find a similar gel to the one we sell at your dentist, but at a much higher price. We only sell products with a concentration of active ingredients that comply with the Dental Association’s recommendations.

Our Whitening System kit has been specially developed by dentists to be safe, convenient and to provide good results. Our method is exactly the same as that used by dentists and there are no studies indicating that it is harmful. Follow our instructions carefully and we guarantee that you will be satisfied.


When you go to a dentist to have your teeth whitened, the mouth trays are produced by hand in a dental laboratory, which is very time consuming and costly. With Swiss Clinic’s Whitening System you get a specially manufactured mouth tray, which you mould yourself. This way you not only save time, but also the cost of manufacturing the mouth trays. The results are the same, but at a much lower price (40-50% less).
