Answer 1

Tooth enamel corrodes when it reacts with acid. When we eat chocolates or sweets, some part of the chocolate/sweet get stuck to the tooth. The small microorganisms present in our mouth degrade these chocolate/sweet by releasing mild acids (pH below 5.5). Thus tooth enamel undergo damage.

To prevent this we must brush our teeth twice a day, using a toothpaste, as toothpaste contain mild base, which neutralize the effect of the acid in our mouth

Answer 2

$\huge \boxed{ \underline{ \underline{ \bf{Answer}}}}$

Tooth enamel is made up of calcium phosphate which gets corroded when the pH in the mouth becomes lower then 5.5. When we take chocolates and sweets, some particles remain in the mouth after eating. Bacteria present in the mouth produce acid by degradation of sugar and food particles remaining in the mouth after eating. This lowers the pH in the mouth and results in tooth decay which starts when pH become lower than 5.5.

This can be prevented by cleaning the mouth after eating sweet food. We can also use tooth pastes which are alkaline and neutralises the excess acid and hence prevent tooth decay.
