Professional teeth whitening allows you to whiten your teeth by several shades. What should you look out for when whitening your teeth?
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.
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*.
The term “bleaching” means to make something whiter and/or to remove stains from it. There are several different bleaching 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.
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.
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.
A thorough dental check-up is recommended before bleaching. We also highly advise to have a professional tooth cleaning before bleaching your teeth in order to remove all plaque and debris. Furthermore, before bleaching, always consult a dentist to avoid damage to teeth and gums.
Please note: the colour of fillings, crowns and bridges cannot be changed by bleaching. The desired result may not be achieved if fillings, crowns or bridges are in the visible area of the dental arch.
Patients who opt for the aligner treatment of both jaws get a home bleaching free of charge. This way, your teeth will not only be straight, but also wonderfully white at the end of your treatment. The bleaching does not require any separate dental aligners, as we already use custom-made aligners for our aligner treatment. The perfect solution to get beautiful and white teeth for your wedding.
