Answer 1

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

Answer:

Sugar present in chocolates and sweets gets broken to acids by bacteria present in the mouth. This lowers the pH in the mouth. Tooth enamel is made up of calcium phosphate, which gets corroded when the pH in the mouth is below 5.5. To prevent tooth enamel from decay, toothpaste is used because it is alkaline and neutralises the acid produced in the mouth and helps to prevent lowering of pH in mouth.
