Importance Of pH In Everyday Life
Do you know why it is advised to clean your mouth after consuming food?
Acids are produced in the mouth due to the degradation of sugar and food particles by certain bacteria. As a result, the pH of mouth is lowered.
pH is the measure of the acidity or alkalinity of a solution. The pH scale varies from 0 to 14. A pH value from 0 to 6.9 represents an acidic solution, whereas a pH value from 7.1 to 14 represents a basic solution. A pH value of 7 represents neutral solutions.
Tooth enamel, which is made of calcium phosphate, is sensitive to pH.It does not dissolve in water (neutral pH), but gets corroded when pH in the mouth is below 5.5.
Hence, tooth decay starts when the pH of mouth is lower than 5.5.
Do You Know:
Toothpastes used by us for cleaning our teeth are generally basic in nature. Hence, it can neutralize excess acid present in the mouth and prevent tooth decay.
Let us study the role of pH in our daily life.
All living organisms are pH sensitive and can survive only in a narrow range of pH.
