Answer 1

Calcium Phosphate.Ca3(PO4)2 They get decayed and in turn decay the tooth.

Answer 2

White tooth enamel is calcium phosphate though a very hard substance, which gets affected when the pH of our mouth falls below 5.5.
It happens because the bacteria present in our mouth break down sugar and food particles into acids which damage our teeth by corroding them. To prevent the tooth decay, after eating one should clean mouth thoroughly with tooth powder or toothpaste, which is basic in nature. It neutralises the excess of acid.
Hope it will help you!!!!!!!
