TOPIC: 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.

The line graph compares the level of acidity in the mouth within 40 minutes since people consumed sweet foods containing fruit sugar, cane sugar, and honey.

Overall, except for the first 5 minutes, the more time people keep these foods in their mouths, the lower acidity it is. Additionally, the environment that facilitates dental erosion is below the level of pH 5.5.

From the moment people put food in their mouths, the acidities of all the three types are the same, at pH 7. Five minutes later, the pH levels fall precipitously, with cane sugar hitting a trough of 3.5, fruit sugar 4.2, and honey 4.8, at which the largest amount of acid was produced.

For the rest of the period, the acid was gradually neutralized. Consumption of honey creates the least chances for tooth decay, which climbs to the safe pH level at minute 14, coming in second was fruit sugar at minute 20, and finally cane sugar at minute 31. All of them continue to rise and reach the highest pH level of 7 at minutes 25, 35, and 40 respectively.

That is not an IELTS Task 1 essay. In these essays, there are no instructions: "discuss the implications. "

In Task 1 you are to refrain from drawing inferences, determining implications, making interpretations and writing about conclusions.

It is task 2 where you are free to write any kinds of opinions, and a conclusion is mandatory.

Note: pH is "potential of Hydrogen" It is a measure of how basic (alkaline) or acidic the liquid is. The scale is 1-14, with 7 being neutral.

I think you are getting these essays from your science class, right?

Students: Are you brave enough to let our tutors analyse your pronunciation?

There are a lot of issues with your understanding of this plot.

1. It is not measuring food containing these sugars, it is the pure sugar (fructose, sucrose and honey).
2. The sugars are not kept in the mouth; they are immediately swallowed.
3. Ph 7 is neutral - neither acidic not alkaline. This is termed "neutral." The experiment begins with the saliva being at its normal value (7)
4. The lower the Ph value, the higher the acidity, so a value of 3.5 is the highest level of acidity measured in saliva, at 5 minutes after eating sucrose (cane sugar).

You missed the most important observations for this experiment. All of them lead to the conclusion that sucrose is much more detrimental than honey, with fruit sugar in between.

  • The mouth acidity levels were at dangerous levels (promoting tooth decay) for 30 minutes, 14 minutes and 9 minutes after ingesting cane sugar, fruit sugar, and honey, respectively.
  • The maximum acidity levels were 3.5, 4.2 and 4.8.
  • The return to normal neutral levels (Ph 7) occurred at 40, 35 and 25 minutes.

Conclusion: Sucrose is the worst of the sweet substances in promoting tooth decay. Not only are the acid levels the highest, but the duration is the longest of the three.



The line graph compares the effects of consuming three different sweet substances, the level of acidity in the mouth within 40 minutes since people consumed sweet foods containing (ungrammatical) fruit sugar, cane sugar, and honey on the Ph levels of saliva. The levels are measured every five minutes from 0 to 40 minutes after intake.


Overall, except for the first 5 minutes, the more time people keep these foods in their mouths, the lower acidity it is. Additionally, the environment (wrong word) that facilitates dental erosion is active below the level of pH 5.5.

From the moment people put food in their mouths, the acidities of all the three types are the same, at pH 7. Five minutes later, at which when the largest amount of acid was produced, the pH levels fall precipitously, with cane sugar hitting a trough (Not a good word, since this is maximum acidity) maximum acidity of 3.5, fruit sugar 4.2, and honey 4.8.

For the rest of the period, the acid was gradually neutralized. Consumption of honey is the least harmful to dental health, as the acidity levels decrease creates the least chances for tooth decay, which climbs to the safe pH level at minute 14. Coming in second was fruit sugar at minute 20, and finally cane sugar at minute 31. All of them continue to rise and reach the highest neutral point, pH level of 7 at minutes 25, 35, and 40 respectively.
