Sample Answer 2: 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. ( These 2 model answers can be followed as examples of standard answers. However, please note there are other good ways of writing possible good answer.) Sample Answer 3:
After the consumption of cane sugar, acidity level of mount increased sharply in five minutes and reached 3.5 pH level. From now onwards acidity level of mouth decreases steadily and reached the normal level after thirty-five minutes. However, teeth remained in dangerous level more than 25 minutes.
Another acidic nutrient is fruit sugar. After the consumption, pH level of mouth decreased hurriedly and reached 4.25 in five minutes. After that, level of acidity of month reached normal level in 15 minutes. Therefore, teeth remained in dangerous level for 15 minutes. The last and the least acidic nutrient is honey, after the consumption of honey acidity level of mouth increased dramatically in five minutes and reached 5 pH level and then, plateau for 5 minutes and from now onward decreased moderately. However, teeth remained in an acidic environment for 10 minutes.
To conclude, the more hazardous nutrient for teeth is cane sugar because teeth remained in an acidic environment for more than 25 minutes.

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. 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: Answers Submitted by IELTS candidates: Answer 1: 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. (Approximately 225 words) Answer 2: As per the graph, tooth decay starts when the PH level falls beneath 5.5 on the scale and it is quite clear that PH level falls rapidly after consuming all three commodities but took least time to recover in case of honey and maximum in case of cane sugar. To start with, the PH level is at 7 and begins to decline after consuming each item and the rate at which it falls is maximum in case of cane sugar. It crosses the danger level within a span of 5 minutes and by the end of 5 minute, PH level reaches its lowest point in case of cane sugar i.e. 3.5 and the same for fruit sugar and honey is 4.25 and 4.75 respectively. After 5 minutes has elapsed, the trend line tends to be inverted and from here on the PH level initiate its recovery in case of fruit/cane sugar though it remains at its lowest in case of honey for a further 5 minute period. On reaching 10 minute mark, PH level in case of honey seems to recover at brisk pace taking over the recovery of other items and reaching the safe zone within a span of 15 minutes. Fruit sugar PH level crosses the line before 20 minutes but cane sugar PH level took almost double the time of honey to recover from tooth decay. Honey PH level normalize by the end of 25 minute mark and the same is 32 minutes and 40 minutes in case of fruit sugar and cane sugar respectively. All in all it can be said that Honey is the least acidic food item and the fastest to recover among the three. On the other hand cane sugar is the most acidic and slowest to recover. Answer 3: 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.
