The graph compares acid level in mouth overtime after people eat sugary foods and the possibility of tooth decay occurrence.
Overall, among the 3 sugary ingredients, cane sugar has the highest risk of tooth decay, while honey is least likely to cause the problem. For PH level, the level 5.5 marks the point where tooth decay occurs.
Looking at the information in detail, the initial PH level is 7 at the moment sweet foods are eaten. The first 5 minutes saw a dramatic increase in acidity caused by the 3 ingredients, with PH level standing at around 3.5 for cane sugar, 4.25 for fruit sugar and 4.75 for honey respectively.
After the intake of honey and fruit sugar, the figures for PH value rise back the safe level at 5.5 after 15 and 20 minutes each, while the same process takes over 30 minutes for cane sugar. In addition, after 25 minutes, the PH statistic for honey recovers to its original level at 7, while it takes 35 minutes for this indicator to return to the initial level after the consumption of fruit sugar. Finally, the PH value for cane sugar consumers recovers after 40 minutes.
