IELTS Writing Task 1: Line graph Samples Part 1

When the pH level in the mouth is above 5.5, acidity remains in such a level that teeth are unlikely to be in danger from decay. Sweet foods, however, cause pH in the mouth to drop for a time, and the longer the pH levels remain below 5.5, the greater the possibility for decay to occur. The illustration compares the fruit sugar, cane sugar and honeys, which are the most common ingredients of sweet foods, causes the pH level to drop below the danger level after 5 minutes.

Among these 3 sweet items, cane sugar decrease the pH level most quickly and causes to remain the level under the danger level for the longest period (over 30 minutes) and thus produce the greatest risk among the three. After consuming the cane sugar, the pH level drops to level 3.5 and remains there for over half an hour. On the other hand, fruit sugar causes the acidity level of mouth to fall under pH level 4 in 5 minutes and remains under threat level for 20 minutes. Finally the honey appears to be less risky among the three causes the pH level to drop to 4.7 in 5 minutes and proceed to above pH 5.5 level within 15 minutes of consumption.

In conclusion all of the sweet items possess the possibility of causing tooth decay and honey and fruit sugar are likely to cause less decay than the cane sugar does.

1. Please note that the question asks you to "describe the information presented in the graph and also discuss the implications for dental health". So you have to mention which food items creates more acid level for longer time and are comparatively injurious for teeth. You must classify which food items are comparatively safe as well. First compare the three food items in terms of the acid level they create in mouth and how long this acid level remains in danger level. Then suggest which food items among cane sugar, fruit sugar and honey is comparatively safe and which item/ items are not.

2. Notice the following trends from the given line graphs:

    a) Higher the acid level, the lower the pH level.
    b) pH level below 5.5 is dangerous for the tooth as the tooth decay occurs below 5.5 pH level.
    c) Honey is comparatively safer than other two food items as it decreases the pH level of the mouth slowly and the acid level goes to the safe level very quickly. On the other hand after consuming cane sugar the pH level falls under danger level quickly and remains there for the longest time among the three food items.

3. To answer this question first mention the acid / pH level which occurs the tooth decay and the level when it is safe. Now take the three given food items and mention them individually: how longer it takes to reach the pH level of mouth below 5.5 after consuming this food item and then how longer this level remains under 5.5. Finally suggest which food items is comparatively safe and which is not. 

Summary of the Line Graph: 
After consuming different sweet food items, the acid level of our mouth increases. The higher acid level is presented by the lower pH value. When the pH value gets under 5.5, the tooth decay occurs. Among the given three food items i.e. cane sugar, fruit sugar and honey, the third item (honey) is comparatively safer for our dental health. This is because after consuming all the honey the pH level remains under danger level for about 12 minutes compared to the 20 minutes for the fruit sugar and 31 minutes for cane sugar. This also indicates that the cane sugar is more likely to damage our tooth among the provided three sweet food items.

Answer 1: 
The given line graph gives information on the acid level produced in our mouth decay after consuming fruit sugar, cane sugar and honey and compares the possible implication those three sweet food items have on our tooth decay. As is observed from the given presentation, honey causes the least tooth decay while the cane sugar possesses the possibility of decaying our tooth among the mentioned three sweet foods.

The graph shows that different acid level is created in mouth after we consume different sweet food items. High acid level is measured by low pH level and tooth decay is occurred when the pH level goes below the 5.5. After we eat fruit sugar, the pH level of our mouth declines below 5.5 in 5 minutes and remain in danger level until 13 minutes. Similarly Cane sugar causes the pH level to get under pH level 5.5 in 5 minutes but it remains in danger level for more than 30 minutes which shows the fact that can sugar can cause more tooth decay than the fruit sugar. Finally, in 5 minutes the pH level of our mouth reaches to danger level in 5 minutes after we take honey and this level remain in danger zone for about 20 minutes.

The comparison of the three sweet items indicate that the honey is comparatively safer for our dental health as it posses the least possibility of tooth decay while cane sugar possesses the most danger to our dental health as it would possibly create the most tooth decay.

Answer 2: 
The given line graph illustrates the various acid levels in the mouth related to three different sweet foods such as fruit sugar, cane sugar and honey. The first point to note is that acid levels due to these different sweets are at a level at tooth decay is unlikely to occur both at the time of eating and after 15 minutes of eating.

At the moment of eating of three sweets, acid levels are very low and equal at 7 pH. Then after 5 minutes it dropped to a pH of 3.5, 4.5, and 5 by cane and fruit sugar and honey respectively. Acid levels in the mouth gradually decrease and reached to minimum value within half an hour of cane sugar eating. Acid variations in mouth after eating fruit and cane sugar are almost equal for the next 5 minutes and followed by a difference of 1 pH value for the next 20 minutes. However, after 30minutes of eating sugar and cane sugar, pH value raised and reached to 7 and the acid level hit to the lowest level.

To sum up, it is clear from the graph that, the given sweets produces high levels of acids in the mouth soon after eating, but reaches to safe level which tooth decay is not likely to occur within 10-15 minutes.
