Teeth whitening – Get white teeth and smile like a star

Professional teeth whitening allows you to whiten your teeth by several shades. What should you look out for when whitening your teeth?

Tooth whitening: bestsmile

Hollywood smile

For many people, a perfect smile means not only having straight teeth, but also white teeth. However, teeth are almost never perfectly white by nature and there are several factors that influence the colour of your teeth. A professional teeth whitening can remove disturbing pigments and thus make teeth significantly whiter.

Why do teeth discolour?

There are 2 types of tooth discolouration:

1: Internal tooth discolouration is caused by the penetration of staining substances. These include medications such as antibiotics. Accidents and dental injuries can cause discolouration due to bleeding or death of the dental pulp. In addition, as we age, the enamel wears away, causing the yellowish dentine to shimmer through the enamel.

2: External tooth discolouration occurs when dental plaque is discoloured by food and stimulants. This happens, for example, when drinking fruit juices, coffee, black tea, red wine or through exposure to tobacco smoke. These discolourations can easily be removed with a professional tooth cleaning.

How are teeth whitened?

There are several different teeth whitening methods, but they all have in common the use of hydrogen peroxide. The bleaching agent (H2O2) penetrates into the tooth where it splits off oxygen radicals (atoms or molecules with at least one unpaired electron). These molecules can change dyes so that they are no longer recognisable and thus whiten the teeth.

The most common teeth whitening methods

Home bleaching

In order for patients to whiten their teeth at home, they need custom-made plastic aligners, which are made with a dental impression or with a 3D scan. Patients can fill the bleaching gel into their individual aligners and place them onto their teeth. Depending on the strength of the bleaching agent, the patient needs to wear the aligners for 1–8 hours. With the home bleaching it is possible to whiten the entire dental arch.

Caution: If attachments are applied during Aligner treatment, it is necessary to wait until these get removed before whitening your teeth.

Power bleaching / In-office bleaching

This type of teeth whitening is performed directly in the dental practice. Power bleaching is more effective in terms of short-term results and intensity, but is only suitable for the 6 visible front teeth. These are covered with a bleaching agent, which should be left on the teeth for 15–45 minutes. The more intensive effect of bleaching agents claimed by various suppliers when used with special lamps or laser light has not yet been scientifically proven. The gums are protected from the strong bleaching agent with a rubber-like coating. Unlike home bleaching, power bleaching can be applied to individual teeth.

Who should generally avoid teeth whitening?

  • Pregnant and breastfeeding women
  • Children
  • People with diseased gums and teeth

A thorough dental check-up is recommended before teeth whitening. We also highly advise to have a professional tooth cleaning before whitening your teeth in order to remove all plaque and debris and to always consult a dentist to avoid damaging your teeth and gums.

Caution: the colour of fillings, crowns, bridges and veneers cannot be changed by whitening. The desired result may not be achieved if fillings, crowns or bridges are in the visible area of the dental arch.
