Answer 2

Answer:

pH is Potential of Hydrogen.

Explanation:

Tooth decay starts when pH of the mouth is lower than 5.5. Tooth enamel made up of calcium phosphate is the hardest substance in the body. It does not dissolve in water, but is corroded when the pH in the mouth is below 5.5. Bacteria present in mouth produces acid by degradation of sugar and food particles remaining in the mouth after eating. The best way to prevent this is to clean the mouth after eating food. Using tooth paste, which are generally basic, for cleaning the teeth can neutralise the excess acid and prevent tooth decay.
