The line graph below shows the cases of diseases caused by X virus in Australia from 1960 to 1995.

The bar graph illustrates the acid level of mouth after consumption of three different nutrients such as fruit sugar, cane sugar and honey over the period of forty minutes. According to the bar graph, it is obvious that cane sugar is the most acidic nutrient.
The given illustration demonstrates the acid level, which is the inverse of the pH values, different sweet foods can create in our mouth and their possible implication for our dental health. As is given in the line graph, high acid levels are measured by the low pH level in our mouth and the lower the pH level, it is more likely to decay the tooth.
