Hi! this side TopperDhruv.

Toothpaste is basic in nature as it contains milk of magnesia. Ot neutralizes the acid made during the breakdown of stucked food in our teeth by bacteria. As a result the pH level doesn't falls below 5.5.

I hope your is query is resolved.

Answer 2

Answer:

P = Ca3 (PO4)2. Bacteria present in the mouth produce acids by degradation of

sugar and food particles remaining in the mouth after eating. Using toothpastes, which

are generally basic, for cleaning the teeth can neutralize the excess acid and prevent

tooth decay.
