Progressive, irreversible loss of dental hard tissues due to a process not involving bacteria. It is a common condition in developed societies that affects people of all ages. The prevalence is not well documented since national dental surveys are not commonly conducted and rarely include measures of erosive tooth wear. In addition, it is often difficult to compare the outcomes of different epidemiological studies on dental erosion due to the use of different examination standards, including scoring systems, samples and groups examined. Since there is not currently enough data to draw conclusions about the prevalence of dental erosion, more studies are needed in order to better understand the epidemiology of this destructive condition.
