With thorough removal of the excesses of the bleaching gel, no side effects are currently known. The occurrence of allergic reactions has not been observed.
The application should be every two to four years. The treatment intervals depend on the personal aesthetic feeling, the regular care of the teeth and the intensity with which one consumes stimulants (wine, cigarettes, tea, etc.).
Basically not. However, it is true that we think that people with white teeth are healthier and our subconscious mind suggests that these people are also physically well-groomed. The tooth color of a patient is very individual and depends on the structure and function of the teeth and their environment. This changes the tooth color in the course of life. Tooth discolorations can be indications of diseases of the tooth hard tissue (caries) and the tooth nerve. In addition, there are dental discolorations due to general health disorders, hereditary dispositions, early childhood medication and excessive fluoride intake. All these causes discolour the tooth from within. In addition, there are, of course, tooth discoloration caused by deposits on the tooth surface.
The most commonly used whitening bleaching agent is hydrogen peroxide (H 2 O 2 ). The decomposition products of hydrogen peroxide, such as radicals, hydroxyl or Perhydroxylionen, represent the active bleaching substance. The unstable H 2 O 2 decomposes into water and reactive oxygen, which splits dyes and destroyed.
Teeth whitening materials from drugstores, pharmacies or supermarkets also cause a whitening of teeth. However, over-the-counter products are only low-concentration preparations. Therefore, these whitening agents do not work so much lightening and not so long-lasting.
The white stripes introduced by the company blend-a-med also use H2O2 in a concentration of 5 to 6.5 percent. Even with the help of these adhesive films, a whitening of the teeth can be achieved. However, the strength and durability of this whitening is very limited according to current experience. So far available results do not give rise to possible side effects.
The so-called smoker toothpastes with an above-average content of abrasives primarily combat external tooth staining, ie the deposits on the tooth surface due to food and semi-luxury foods or medicines. The regular use of such smokers toothpastes is not recommended. The abrasive particles contained therein together with an often too high contact pressure of the toothbrush in oral hygiene lead to injuries of the enamel surface. So it is not uncommon that non-carious caused enamel defects caused by regular use of such toothpastes and excessive force in oral hygiene. In particular, after intake of acidic foods and drinks for one hour should completely omit the dental care.
