      The given line graph provides information about the acid level produced in the mount after eating three different types of the sweet foods including fruit sugar, cane sugar and honey and its effects on the dental health over a period of forty minutes.
      Overall, it is clear that tooth decay is almost impossible to occur when the PH levels in the mouth below 5.5. (PH and acidity values are inversely proportional to each other). Otherwise, if the PH values are above 5.5. All studied sweet food categories cause the tooth damage during the researched specific time. Fruit and cane sugar remain the PH level which is below 5.5 in the longer time than honey resulting from the higher risk of the tooth decay.
      There was a rapid increase in the amount of acid after eating of three represented sweet foods kinds for the first 5 minutes. Among these three sweet items the PH level of Cane sugar drops most quickly, from 7 to 5.5 and to 3.5 for exactly 5 minutes and remain in the danger level (below PH 5.5) for the longest period, at nearly 30 minutes compared with 15 minutes for fruit sugar and 7 minutes for honey, respectively before returning to the safe level (above PH 5.5). The figures of the PH level for fruit sugar and honey after 5 minutes of consuming are 4.5 and 4.7 respectively.
