Acid level in mouth from consumption of sugar/honey

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 5.5 is detrimental for the tooth and causes the tooth decay.

The given graph shows that the initial pH level of our mouth is 7 which begin to fall after consuming sweet foods. When we eat sweet item like cane sugar, the pH level drops to 3.5 in 5 minutes and remain in danger level (below pH level 5.5) 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 level falls below 5 and it remains under risk level for about 13 minutes. As the low pH level means higher acidity and causes tooth decay, cane sugar among the mentioned three food items is the most harmful for our tooth.

Sample Answer 2:
The provided line graph shows the acid level of our mouth which is created by the consumption of fruit sugar, cane sugar & honey and compares their effects on our tooth decay.

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 honey, 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 decreases 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.

Tips for answering this Writing Task 1 Question:

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 item creates the highest acid level for a longer time and are comparatively injurious for our 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 our mouth and how long this acid level remains in danger level. Then suggest which food items among cane sugar, fruit sugar and honey are comparatively safer 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 are comparatively safer and which are 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.


Sample Answer 3:
The bar graph illustrates the acid level of mouth after consumption of three different nutrients such as fruit sugar, cane sugar and honey over the period of forty minutes. According to the bar graph, it is obvious that cane sugar is the most acidic nutrient.

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, the pH level of mouth decreased hurriedly and reached 4.25 in five minutes. After that, the level of acidity of month reached a 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.

Sample Answer 4:
The given line graph gives information on the 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 are related to the tooth decay.

The maximum level of acidity produced by sugar content is reached 5 minutes after consuming them reaching up to 3.5 pH for sugarcane, 4 pH for fruit sugar and 5 pH for honey. After this time the acidity level declines for cane and fruit sugar, whereas it is sustained for 10 minutes for honey. Honey takes approximately 15 minutes to reach the pH of 5.5. It is at this pH at which tooth decay is unlikely. Fruit sugar takes 20 minutes and cane sugar takes the maximum time to reach this safety level. After 40 minutes all three sugars reach neutral pH that is 7.

Acidity promotes tooth decay which results in teeth cavities. Proper brushing and mouth washing can eliminate sugar particles and may protect teeth from the hazards of high acid levels.

From the given data it is clear that cane sugar has highest acidity and its acid content above safety level is sustained for the longest period in our mouth. Therefore it should be avoided. Honey is the safest sugary food which causes least chances of tooth decay.

Model Answer 5:
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.The  higher acid level is measured by the lower pH level and tooth decay is likely when the pH level in our mouth goes below 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 remains in the danger zone for about 20 minutes.

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

Sample Answer 6:
The given graph depicts comparison in acid level in mouth after consuming sugar/honey. One axis of the graph contains PH level which measures acidic level and the other axis reflects timeline after consuming, spaced out equally with 5 minutes gap.

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 the least time to recover in case of honey and the maximum is in the 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 minutes, PH level reaches its lowest point in case of cane sugar i.e. 3.5 and the same for fruit sugar and honey, which are 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 the 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 normalise by the end of 25 minute's 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.

 

Model Answer 7:
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 the 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 a safe level which tooth decay is not likely to occur within 10-15 minutes.

Model Answer 8:
The provided line graph illustrates the acid level in the mouth which is caused by the consumption of cane sugar, fruit sugar, and honey. As is shown in the graph, the higher the acid level, the lower the pH level. It is also illustrated that a pH level less than 5.5 is the stage when tooth decay occurs.

It is significant that the initial pH level in our mouth is 7, and it drops the moment we eat sugar. In the first 5 minutes, the graph shows that eating cane sugar results in a major drop in the pH level which reaches 3.5 and then begins to increase very slowly in half an hour. During this phase, tooth decay is most likely to happen. It is almost the same when eating fruit sugar, as the pH level drops to less than 4.5 in 5 minutes, and remains in detrimental level for about 20 minutes. Moreover, the pH level drops to less than 5 when honey is taken, and it possesses the threat of tooth decay for only 10 minutes. So, honey is the least dangerous among the three kinds of food items.

In summary, it appears that cane sugar is the most detrimental one for our dental health while honey is the safest one.

Model Answer 9:
The given illustration demonstrates the acid level, which is the inverse of the pH values, different sweet foods can create in our mouth and their possible implication for our dental health. As is given in the line graph, high acid levels are measured by the low pH level in our mouth and the lower the pH level, it is more likely to decay the tooth.

According to the line graph, fruit sugar, cane sugar and honey cause different acid levels in our mouth and their impacts last for five to 30 minutes. The pH level below 5.5 is detrimental for our tooth. When we consume honey, the pH level of our mouth decreases to below 5.5 within 4 minutes and that takes around 13 minutes to come out from the danger level. In the case of fruit sugar, the pH level goes below 5.5 in 3.5 minutes and remains in danger level for about 20 minutes. Finally when we eat cane sugar, the pH level of our mouth goes in the danger level in 2.5 minutes and remains in danger level for about 32 minutes.

In short, honey is the safest sweet food for our dental health while cane sugar is most detrimental for our tooth as it is likely to cause the maximum decay in our tooth.

Model Answer 10:
The line graph illustrates how the lower pH levels in the mouth, which are produced by eating sweets, causes tooth decay. It is clear that the acid levels are indirectly proportionate to the pH levels and pH level less than 5.5 is favourable to tooth decay.

To launch into the topic, Undoubtedly, the highest acidic levels are due to cane sugar which causes pH 3.5 within 5minutes and these unsafe levels maintain up to half an hour after consumption. Then the second given cause to drop pH level(4) in the mouth is fruit sugar and it takes approximately 20 minutes to levelled off. Moreover, the last but not least important cause given here is honey. Though it resulted in soaring mouth pH level up to 5, it drops down to a healthy level within 10 minutes after consumption.

To summarise, even though, the given sweet foods increase mouth acid levels within the span of 10 minutes, they take exactly 40 minutes to reach pH 7 after eating which is the safest level that does not cause tooth decay.

Model Answer 11:
The line graph gives information about the acidity level of the mouth after ingesting three different sweet items- fruit sugar, cane sugar and honey over forty minutes. The lower the pH level of the mouth, the more acidic it becomes making it highly conducive for tooth decay formation.

A pH level of 5.5 and above indicates a safe zone, which means tooth decay, is unlikely to occur. Consequently, the pH value below 5.5 is considered as the danger zone, which gives higher chance for the dental problem to happen.

The line graphs show that the cane sugar is the most dangerous among the three sweets products mentioned. It becomes highly acidic at the pH level of 3.5 after 5 minutes of consumption and remained acidic for almost half an hour. On the other hand, fruit sugar becomes acidic (4.2 pH level), five minutes after consumption but reached the safe level of acidity after fifteen minutes. In contrast, honey gets the lowest acidity level (almost 5 pH level) after five minutes of ingestion and plateau on this level for another five minutes, then steadily decreases the acidity in the mouth, and thereby crosses the danger zone after 15 minutes of consumption.

In summary, all the three sweet items have a chance to cause the tooth decay. However, among the three, honey is less likely to cause dental problems as it loses its acidity faster compared to fruit and cane sugars.

The provided line graph illustrates how the lower pH throttling in the mouth, which are produced by eating sweets, causes tooth decay. It is clear that the acid levels are indirectly proportionate to the pH throttling and pH level retailing checkbox 5.5 is favourable to tooth decay.

To launch into the topic, undoubtedly, the highest acidic levels are due to the cane sugar which causes pH 3.5 within 5minutes and these unsafe throttling maintain up to half an hour after consumption. Then the second given cause to drop pH level approximately 4 in the mouth is fruit sugar and it takes to 20 minutes to be levelled off. Moreover, the last but not least important cause given here is honey. Though it resulted in soaring mouth pH level up to 5, it drops down to a healthy level within 10 minutes after consumption.

To summarise, cane sugar consumption causes the maximum tooth decay, the honey is comparatively safer to consume as it causes the minimum amount of tooth decay among the given three sweet items.

The supplied line graph depicts the comparative study of three sugar-containing compounds and their effects on teeth with the passage of time. As can be seen from the given illustration, increasing acidity is produced just after eating any sweet item and the increasing acid level in the mouth is measured by the low pH value.

The safe level of the pH to protect the teeth from decay is above 5.5. Overall, the acidic effect of cane sugar on teeth is longer than other two types. In addition to this, all sugary compounds cause tooth decay by reducing the pH level of mouth below 5.5. The striking feature of this graph is the cane sugar's effect on teeth, which results in the pH level's drop suddenly from normal to around 2 in five minutes. In contrast, the pH of mouth reduces around 5 with the use of honey within five minutes. Another prominent feature is an effect of fruit sugar, which decreases the pH from 7 to 4.25 approximately in five minutes. The acidic effect of honey, fruit sugar, and cane sugar neutralise in about 25 minutes, 33 minutes and 40 minutes respectively.

The given data implies that any sweet item can cause tooth decay. However, honey comparatively causes less amount of damages to our dental health than the cane sugar.

The line graph provides information about the acid level produced by three different sweet food items (Fruit sugar, Cane sugar and Honey) in our mouth and the the possible tooth decay they can cause. In terms of acidity, the lower the pH level the greater the acidity. Thus, pH level less than 5.5 can cause tooth decay.

Overall, cane sugar, if consumed by human, can cause tooth decay more than fruit sugar and honey.

The cane sugar, which represents a green line in the graph reaches the lowest pH level, which is presented by the highest acidity level, in 5 minutes of consumption and it takes 30 minutes to reach the pH level in safe zone. On the other hand, fruit sugar, the red line in graph, has pH value around 4 after 5 minutes of consumption and it exposes our teeth for possible decay for about 20 minutes from the consumption. Lastly, blue line represents honey and within 5 minutes of its consumption, the pH value in our mouth reaches to just below 5. However, in less than 15 minutes the pH level reaches to a safe zone when no tooth decay is caused. It is clear in the graph that honey is the safest food sweet food items among the given three for our dental health while cane sugar might cause the highest amount of tooth decay.

The provided line graph illustrates the effects of fruit sugar, cane sugar and honey consumption by human which produce acid in the mouth and put the dental health in danger for about 40 minutes. The high acid level is measured by low pH value and lower the pH value, the more harmful it is for our dental health.

Based on the graph, we can see that the production of acid in mouth highly increases with the consumption of these three sweet food items. Initially, the pH level created in mouth from these three foods starts from 7 and it dramatically decreases to below pH 5.5 within 5 minutes of consumption. As a result, this dropping of pH level is signed to occur tooth decay whenever the level is below 5.5. During the period of 5 to 40 minutes, the level of these three foods rapidly jumps from highly acidity to low acidity (neutral pH). A rapid drop of pH level could be observed for the consumption of cane sugar and it remained in danger level for more than 30 minutes. Consumption of fruit sugar drops the pH level below 5.5 for less than 20 minutes while honey seems to cause the least tooth decay as the pH level of mouth from the consumption of this item remains below 5.5 for the least amount of time- about 13 minutes.

The provided line graph compares the acid level in our mouth as time elapses during 40 minutes after consuming fruit sugar, cane sugar and honey as well as the likelihood of tooth decay after eating them.

Generally speaking, the pH level is seven at the moment we eat sweets before falling dramatically to just between 3.5 and 4.5 after 5 minutes, the acid level at which tooth decay most possible to occur (being under the level of 5.5 is detrimental for our tooth). In the next 35 minute period, the acidity in mouth undergoes considerable increase and back to its formal level at seven at the end of the period.

Turning to the comparison between the acid level resulted from three kinds of sweets, it is clear that cane sugar causes the highest acidity and remains the lowest pH level over the period with a bottom of approximately 3.5 after 5 minutes consumed and keeps being under 5.5 in 30 minutes. Hence, cane sugar causes more tooth decay. Honey and Fruit sugar, on the other hand, record lower acidity than that of cane sugar and get out of the level which is harmful to the tooth after 15 minutes and 20 minutes respectively.

In short, 5 minutes after eating sweets is most likely to cause tooth decay, especially when we eat cane sugar.

The given graph shows the level of acid produced by consumption of different sources of sweets including Cane sugar, Fruits and honey. Overall tendency of all types of sweets are almost the same, increasing acidity at first, by decreasing PH level, during the first 5 minutes and then increasing PH again that means dropping acidity in the mouth.

As observed from the graph, PH level lower than 5.5 results in tooth decay in the mouth and it seems important to have precise look over the behavior of foods including sweet ones. As the graph depicts all three types of sweet foods make the mouth acidic during the first few minutes and keep the mouth acidic even more time as well. As seen in the given illustration, honey makes the lowest acidic condition and touch the lowest PH point at almost 5, while fruit and cane sugar make the PH level drop to the almost 4.2 and 3 respectively.

On the other hand, acidity produced by honey consumption drops faster than other two sources and Ph condition, in this case, rise up to standard condition just before ten minutes after consumption, since fruit and cane sugar keep the mouth acidic more and about 20 & 35 minutes respectively that means more harms to the teeth.

In conclusion consumption of all types of mentioned sweet foods result in harmful condition on teeth. So it seems definitely important to wash the teeth just after the sugar consumption and within 3 minutes. Additionally graph reveals that honey has the least danger on teeth and cane sugar has the most and the longest acidic condition, so the worst effect, on the teeth.

The line graph supplied depicts the correlation between the acidity level caused by sugar/honey release in the mouth by three selected food items (sugar, Honey and Sugar cane), with time. The X-axis represents the time taken for the acid to accumulate (in minutes), and the Y-axis represents the level of acid present in the mouth with increase in time – this is measured using the pH scale. The graph suggests that the lower the pH value, the higher the acidity level. Generally speaking, it can be observed that for all the three food items, an increase in time from 0 minute to 5 minutes will lead to a rapid increase in the acidity level of the sugar or honey released in the mouth. But beyond this time, the reverse becomes the case. The graph also shows that any acidity level above 5.5 pH value will not lead to teeth decay irrespective of the amount of time the food has stayed in the mouth.

The graph suggests that at the point the food is eaten and the sugary substance released in the mouth, the pH value will be at 7. This is true for all the three food items under consideration. However, with time, and comparing the three food substances, honey accumulates the highest amount of acidity, followed by fruit sugar and then the cane sugar. This is represented by the steepness of the individual slopes between this first 5 minutes time frame. The acidity level for honey continues to increase until the five minute turning point when it levels out until about another five minutes and then begins to decrease as the slope rises steeply until the twenty-fifth minute when it plateaus till it terminates at the thirty fifth minute.

For the fruit sugar and cane sugar, the acidity increases until the turning point of 5 minutes then increases sharply until the 40th minute when they terminate. It can be observed that the cane sugar has the higher acid forming potential in the mouth than the fruit sugar since it maintain a relatively lower pH-value throughout the time duration.

The given line graphs illustrates the function of sugar sources namely honey, sugarcane and fruits, and time to acidify and decay our tooth.

Our tooth are normally neutral (pH 7.0) in reaction, and when exposed to sugar, it tends to become acidic. As its pH falls below 5.5 (threshold pH), it begins to decay. This threshold pH is reached within 2.5 minutes, 3.0 minutes and 3.5 minutes when we consume table sugar, fruit sugar and honey respectively.

Normally, after five minutes exposure to sugars, tooth pH tends to rise. In case of cane sugar exposed tooth, the threshold level is crossed only after 32 minutes. But, when we intake honey sugar, this level is earlier about 13 minutes after we intake. Fruit sugar shows intermediate in behavior.

To sum up, sugar- irrespective of its sources- can decay our tooth when exposed even for short duration; and among the different sources, table sugar has the strongest damaging effect and the honey the least.

The bar graph illustrates the acid level of mouth after consumption of three different nutrients such as fruit sugar, cane sugar and honey over the period of forty minutes. According to the bar graph, it is obvious that cane sugar is the most acidic nutrient.

After the consumption of cane sugar, acidity level of mount increased sharply in five minutes and reached 3.5 pH level. From now onward 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.
