Answer 1

Explanation:

Tooth Enamel is chemically calcium hydroxy apatite.

It starts corroding if the pH in our mouth is less than 5.5.

When food particles left in our mouth degrade,the food and sugar particles result in formation of acidic medium which results in tooth decay.

Doctors suggest use of toothpaste as toothpastes are basic&used for cleaning and neutralising the excess acid so as to prevent tooth decay.
