An international team of scientists from Swiss and Brazilian universities found no difference between toothpastes that claim to “protect against enamel erosion,” “strengthen enamel,” or “reduce tooth sensitivity” from control pastes.. Moreover, it turned out that all pastes are equally abrasive and none of them can reverse the abrasion of the enamel, according to the Internet publication for girls and women from 14 to 35 years old Pannochka. net With caries, the enamel decomposes under the action of bacterial enzymes, but sometimes mechanical erosion leads to the fact that the dentin is exposed and the tooth becomes sensitive to hot, cold and touch. “One of the causes of dentin opening and sensitivity is the erosion of the enamel that occurs when we brush our teeth.. Therefore, for our study, we chose those toothpastes that promise to fight erosion or sensitivity,” explains Samira Helena Joao-Souza, one of the authors of the study..

Scientists subjected human teeth donated by a dental clinic to five cleaning cycles using nine toothpaste brands popular in Europe and Brazil with “anti-erosion” or “desensitising” properties and one control paste, and measured the loss of enamel substance.. It turned out that all the tested pastes in one way or another contribute to the loss of enamel substance and none protects against erosion and abrasion.. Moreover, the difference between pastes of different brands turned out to be as insignificant as the difference between the "

Toothpaste should be used for its intended purpose - to serve as a weak abrasive agent and help remove food debris from the teeth, as well as disinfect the surface of the teeth and gums. But it cannot be used as a medicine, including as a cure for enamel erosion or tooth sensitivity, the authors of the article note.. According to Joao Sausa, only three rules can protect against enamel loss: timely visits to the dentist, regular dental hygiene and diet.. Relying on the protection of toothpaste, according to scientists, is impossible.

The scientists published the test results in the journal Scientific Reports..
