Erosion of tooth enamel is also caused by flavored water and sweeteners

Sweeteners can cause exogenous erosion of dental enamel according to a new study that appeared in the International Journal of Environment and Health.

The study looked in particular at aromatized mineral waters that more and more people are drinking instead of sugary drinks. However, even flavored mineral waters contain sugary solutions and the fact that they give the sensation of bringing less damage can already intrinsically lead to greater consumption.

According to this study, switching to sugar substitutes may not be the solution to the problem of tooth enamel erosion. The study was conducted by Anna Lewandowska and Marzena Joanna Kuras of the Warsaw University of Medicine. The two researchers examined various flavored mineral waters sold in Poland, analyzing the pH, acidity and phosphorus concentration levels.

Using solutions of xylitol, erythritol, stevia and glucose-fructose, the two researchers have understood the effects that sweeteners in these drinks can have in the laboratory on tooth enamel.
Analyzing in particular the phosphorus released by the hydroxyapatite, the two researchers realized that both the aromatized mineral water and the sweeteners tested in the laboratory caused erosion of the tooth enamel and this erosion potential was similar to that of glucose syrup- fructose.

It follows, according to the two researchers, that “the replacement of glucose-fructose syrup with another sweetener has no beneficial effect on exogenous erosion.”
