This question justifiably comes up again and again both in our mailbox and in various discussion groups. Science has also already devoted itself to answering the question.
At this point we summarize the most important statements of the current status and would like to take away your last doubts.
Professional whitening is usually done by the dentist, while teeth whitening is suitable for home use. Both methods use hydrogen peroxide to lighten the skin. The main difference, however, lies in the concentration of the active ingredient. Over-the-counter tooth whitening gels may contain a maximum of 0,1 percent hydrogen peroxide in Germany. Dentists usually use a gel with a concentration of 15 to 35 percent hydrogen peroxide.
In today's research there is a consensus that peroxides per se in no way lead to damage to enamel or dentin. Demineralization, etching or the like can be ruled out if whitening systems are used in accordance with the manufacturer's instructions.
The dosage for home bleaching is so low that there is no risk of damage if used properly. If you tend to have particularly sensitive teeth or if you have injuries in the oral cavity, we recommend a prior examination by the dentist.
To protect your health, you should pay attention to high-quality products. Avoid using whitening systems from abroad - these may not be subject to the strict EU regulations.
