Stiftung Warentest: Whitening toothpastes are given the original tooth shade, but teeth usually do not whiten such products
The Stiftung Warentest tested 21 whitening toothpastes and found that they were "good" to "very good" against stains and deposits on tea, coffee, nicotine or red wine. This way the original color of the teeth is preserved. However, as stated on most packaging, regular use does not make the teeth lighter. Therefore, some critics repeatedly question the basic benefit of such toothpastes. None of the whitening toothpastes tested was harmful to health.
Almost all tested whitening toothpastes promise "bright white teeth", but in reality the products are at most suitable for preserving the existing tooth staining, reports the Stiftung Warentest. Consumers should not expect miracles from special toothpastes for white teeth, according to the Stiftung Warentest judgment. However, stains and discolorations are removed from the whitening toothpastes “well” or “very well”.
Whitening toothpastes remove stains and discoloration The Stiftung Warentest had a total of 21 whitening toothpastes examined in the laboratory and checked their dental effects. The testers focused not only on the alleged effect as a whitening agent, but also on the general removal of stains and impurities, the prevention of caries and the abrasion caused. The laboratory also determined how much fluoride the toothpastes contained in order to be able to make statements about caries protection. The fluoride content is particularly important because the salts prevent tooth decay and compensate for weak spots in tooth enamel, the Stiftung Warentest explained. Overall, all toothpastes worked “well” or “very well” against stains and discoloration, with hardly any differences between the cheap products from Lidl, Aldi or dm compared to the expensive branded products from Zahnweiss or Rembrandt, according to the testers' conclusion.
Fluoride content of toothpastes sometimes only "satisfactory" From a dental perspective, however, Stiftung Warentest's verdict on whitening toothpastes is less clear. Some toothpastes have not been completely convincing, especially with the fluoride content. Although most whitening toothpastes scored "good" in the test, the branded articles "Plus Premium Whitening Toothpaste" from Rembrandt and "Professional Dental Repair & White Remineral Teeth" from Perlweiss only received the grade "satisfactory". The most expensive product in the test - the toothbrush from Rembrandt (11.80 euros per tube) - contained less effective sodium monofluorophosphate instead of sodium fluoride, according to the results of the laboratory test by the Stiftung Warentest. Perlweiss toothpaste (9.95 euros per pack) also contained a relatively small amount of fluoride, whereas all cheaper products were convincing in terms of their fluoride content.
Beware of damaged teeth or exposed tooth necks Harmful to teeth or tooth enamel, as was often assumed, was, according to the results of the Stiftung Warentest, none of the whitening toothpastes tested. However, care should be taken with damaged teeth, sensitive gums and exposed tooth necks. According to Stiftung Warentest, consumers should best choose toothpaste with the least possible abrasion. The organic toothpaste from Vitadent has proven to be particularly suitable for this. Overall, each of the toothpastes tested is suitable for strengthening the health of the teeth, but discoloration and deposits cannot be avoided entirely with them either. Therefore, according to Stiftung Warentest, regular professional tooth cleaning is recommended regardless of daily dental care. The complete result of the examination of the whitening toothpastes is published in the April issue of the magazine "test". (fp)
