Zahn Bleaching

Bleaching is a dental process used to brighten the color of your own natural teeth and smile.

This whitening procedure requires no removal, cutting or etching of your dental enamel. Products like tea, coffee, red wine, tobacco, and the natural aging of your denture turn them darker or stain them over time.

A professional dental whitening is performed with the aid of active oxygen, which decolorizes the distracting color pigments present in the tooth. There are dental aids and products which allow for tooth whitening treatment from the comfort of your own home, however we will concentrate on the dental procedures performed in the clinic for now.

In the upper part of the image, you can see the yellowish tooth color prior to the bleaching procedure; below, you see the patient after the bleaching procedure.


The Tooth Whitening Procedure

First, the gums are covered with a special rubber compound – this is done in order to protect them from the bleaching agent. It’s only possible to brighten one’s own natural teeth (crowns, bridges, or veneers can’t be bleached). This is one of the reasons why teeth whitening is the ideal starting point for a ceramic-technical provision.

After the gums have been covered and the denture has been dried, a solution is prepared by mixing two phases, which are then applied to your teeth. Prior to the whitening, it’s imperative that a dentist perform a check of the individual teeth, fillings and entire dental area; if necessary, faulty fillings must be replaced and/or a professional cleaning (oral hygiene) undertaken.

After the appropriate exposure time, the bleaching solution is removed and the mouth are rinsed with water. At this time, the gum protection is removed as well. A professional tooth whitening may be performed safely every two years.

Your denture is just as individual as you yourself. As you can see in these images, there is no doubt that they will become brighter – how much lighter depends on your teeth’s base color. Depending on the degree of discoloration, a brightening of about 1 – 14 degrees is possible.

The result usually lasts for 1-3 years or longer, depending on your own good dental care as well as regular professional oral hygiene. In cases of heavy consumption of discoloring substances (alcohol, nicotine, red juices, tea, coffee, cola, red wine, mustard, ketchup, etc.) as well as poor oral hygiene, the result will not last as long.


Tooth Bleaching - Risks and Results

To date, there hasn’t been any scientific proof of better whitening results by exposing teeth to a halogen lamp and/or a laser – instead, the teeth just dry out more. Although this seems to lead to “better” results, these results are short-lived because the effect lasts no more than 1-2 days. However, the disadvantage of the lamps is that the teeth could be damaged due to the drying, which is why lamps or lasers should not be used in teeth whitening treatments nowadays.

The effects of the brightening on your health are insignificant; nevertheless, complications may occur in individual cases, possibly requiring additional measures. Every additional measure may in turn lead to health complications, which may even lead to the loss of a tooth in the course of treatment. At this point, we will only discuss the specific complications encountered in bleaching – they are, for instance:

  • Sensitive tooth necks, e.g., in case of a careless or incorrect application of the bleaching substance, eg.peroxide
  • Toothache, e.g., in case of leaky fillings
  • Spotty teeth, e.g., in case of an incomplete covering of the (soon to be) white tooth with the bleaching gel

However, all of these complications can be prevented with careful work. Try the find a dentist search on checkdent to find a good dentist to brighten your smile today!
