Who wants to emulate the celebrities from film and television, should know - most of them had at the beginning of their career anything but perfect white teeth.
Because of course, white teeth are not. But it can help. But what are the different methods?
Everybody is born with a different tooth color, it is genetically predisposed and becomes more and more yellow in the course of life. "In the dental technology twelve different shades are distinguished," says Helmut Kesler, dentist from Berlin. The individual tooth color also changes by the consumption of strongly pigmented foods such as red wine, coffee, black tea, beetroot or blueberries.
"Such deposits are deposited in the enamel surface and are difficult to get back down," says Kesler.
The older the teeth, the more susceptible they are to discoloration, as the surface becomes rougher by brushing over time. Pigments are easier to store.
Whitening Toothpaste is designed to help remove these deposits. Ultimately, however, it reinforces the recoloring effect. "The abrasive components of such toothpaste usually only cause the teeth to become rougher and to store in new pigments," explains Kesler.
In addition, the toothpaste can never make your teeth whiter than they originally were. Annegret Blume, Managing Director of the Cosmetics Commission of the Federal Institute for Risk Assessment (BfR), warns against excessive use: "Those who use excessive amounts of such toothpaste risk attacking their teeth with too much abrasion."
As the most effective natural remedy for brighter teeth, Dirk Kropp recommends regular, thorough brushing of the proDente initiative. "This includes the interdental spaces," he explains. To achieve the, facilitate flossing and special brushes.
"The toothbrush should be changed every three months," says Kropp. "The bristles are then worn and bent, so that a pinpoint, technically clean cleaning is no longer possible."
In addition, professional dental cleaning in the dental office can have a whitening effect. While not all areas of the mouth are often reached while brushing at home, the professionals in practice have not only all the teeth in view, but also other tools and pastes available. "You can, for example, polish out cracks and use the abrasive particles in the paste individually, depending on the degree of discoloration," explains Kesler.
If that's not enough, there are only two options left on the way to Hollywood laughter: whitening or veneers. In teeth whitening, the teeth are bleached by chemical means, usually hydrogen peroxide.
How much of it may be included in the over-the-counter bleaching strips or gels is precisely regulated. "This chemical bleaches the hairdresser's hair," says Annegret Blume from BfR. That shows how aggressive hydrogen peroxide is.
"The European Cosmetics Regulation stipulates that a whitening product may contain a maximum of 0.1 percent hydrogen peroxide," explains Blume. This would exclude a health hazard.
Dirk Kropp from proDente points out, however, that due to the low concentration, the hoped-for lightening effect can be disappointing. Added to this is the handling: "If bleaching strips are used improperly, chemical agents can irritate the mucous membrane, ie the gums."
A bleaching at the dentist excludes these disadvantages, but is correspondingly more expensive. Helmut Kesler estimates the costs depending on the practice up to 1000 euros. For professional teeth whitening usually two sessions of 45 minutes are necessary.
