How can I whiten my teeth safely?

What causes tooth discolouration?


There are many causes, the most frequent include the natural aging process, the consumption of certain foods or beverages (e.g. tea, coffee, coke, red wine, and tobacco), injury, antibiotics, strong fluorides, nerve damage and previous dental treatment. Many foods or beverages contain coloring agents.

How can I keep my teeth white?

We recommend using After Bleaching Mousse after a tooth whitening treatment. This gel can prevent sensitivity and can be used after any whitening treatment.
To protect and maintain your white smile, use the Whitening Toothpaste which fights colour-causing bacteria on the surface of your teeth. For the best results, start using the toothpaste before bleaching in order to lower the risk of sensitivity.

Are tooth whitening products and treatments safe?

To date there is no research which shows that tooth bleaching done under the supervision of a dentist causes damage to the structure of your teeth.

What is the difference between a tooth cleaning procedure and tooth bleaching?

Over time, all teeth will be affected by some degree of discolouration. Some kinds of discolouration can be removed with the help of a professional tooth cleaning procedure, but others require bleaching and this can best be done safely with the help of your dentist.

Will bleaching whiten crowns, fillings, veneers, etc.?

Dental treatments like these are usually made to match surrounding teeth and do not change colour over time, compared with real teeth which will change. Slight differences in colour will not be noticeable.

If dentures are available in the visible range and became whiter than the natural teeth over time, a tooth whitening can give back a unified picture. If the dentures are much darker than the natural white teeth, then it is recommended to replace the restaurations after a Tooth Whitening treatment.

Tip: In order to match fillings, crowns etc to the colour of the teeth, it is advisable to get bleaching treatment done before, especially when the tooth or crown is visible. By doing so you can ensure your dentally enhanced smile is white too!

Which tooth coulour would you like to have?

With bleaching, the best results can be achieved at the dentist. But how can tooth colours be determined?
The VITA company (in Bad Säckingen, Germany) is the world leader in terms of defining teeth colour shading. The majority of doctors trust and use the colour charts made by VITA.
VITA has recently produced a new colour chart – the VITA Bleachedguide 3D-MASTER®. With this you can see immediately how successful your tooth whitening procedure has been. All WHITEsmile® whitening kits come with this colour chart. You can also order it directly from us.
