Eating sweet foods produces acid in the mouth which can cause tooth decay
Eating sweet foods produces acid in the mouth, which can cause tooth decay. (High acid levels are measured by low pH values)
Describe the information below and discuss the implications for dental health.
Sample answer 1:
The provided line graph illustrates the acid level in the mouth which is created by consuming sweet foods specifically sugar and honey and possibility of tooth decay because of this acid level. As is presented in the line-graph, the higher the acid level the lower the pH value and a pH level less than is detrimental for the tooth and causes the tooth decay.
The given line graph gives information on amount of acid produced in our mouth by eating sugar and honey made from three different resources namely fruit, sugarcane and honey. Also the graph estimates the time taken by them to reach different acid levels which is related to the tooth decay.(没说好没说坏,用be related to)
 
The given graph shows that the initial pH level of our mouth is 7 which begins to fall
after consuming sweet foods. When we eat sweet item like cane sugar, the pH level drops to in 5 minutes and remain in danger level (below pH level ) for more than 30 minutes. Consuming fruit sugar drops the pH level nearly to 4 and remains in danger level for about 20 minutes. And finally when we eat honey, the pH lev
