The increasing prevalence of dental erosion anddental hypersensitivity has led to the emergence of more and more toothpastes on the market that claim to treat these problems. However, none of them seem effective in the fight against this dental disease, according to the results of a study published in the medical journal Scientific Reports.
Researchers from the University of Bern in Switzerland and those from the São Paulo Research Foundation in Brazil tested 8 common toothpastes claiming to be “desensitizing” and a control toothpaste, all available in pharmacies in Europe. They also analyzed how interactions of chemical and physical factors influenced tooth wear.
The scientists used human premolars donated for scientific research, artificial saliva and an automatic brushing machine.
To test the effectiveness of toothpastes, tooth enamel was exposed to acidity for 5 consecutive days. Thanks to a chemical analysis, the researchers measured for each toothpaste, the pH and the levels of tin, calcium, phosphate and fluoride.
Dental erosion cannot be treated with toothpaste alone
The results of the study showed that none of the nine toothpastes analyzed were able to attenuate the loss of enamel surface, a key factor in dental erosion and tooth hypersensitivity.
Patients should consult a dentist, who will provide a diagnosis and advise them on the best strategy to treat each particular case.
“Toothpaste will not completely solve the problem. Tooth erosion is multifactorial. Diet is a risk factor. Food and beverages are increasingly acidic due to industrial processing,” said Samira Helena João-Souza, a doctoral student at the University of São Paulo School of Dentistry (FO-USP) in Brazil and first author. of the item.
