Eating sweet foods produces acid in the mouth, which can cause tooth decay. (High acid levels are measured by low pH values)

The provided line graph illustrates the acid

level

in the mouth which is created by consuming sweet foods specifically

sugar

and honey and the 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 to the

tooth

and causes

tooth

decay. The given graph shows that the initial

pH

level

of our mouth is 7 which begins to fall after consuming sweet foods. When we eat sweet item like cane

sugar

, the

pH

level

drops to 3.5 after 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 at 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

.

Overall

, As the low

pH

level

means higher acidity and causes

tooth

decay, cane

sugar

among the mentioned three food items is the most harmful to our teeth.
