Answer 2

Answer:-

Hope it helps you...☺☺☺

Explanation:-

Toothpastes are usually weakly basic in nature. PH of saliva is 7.4, which is basic too. An acidic environment will cause teeth enamel to corrode, and will ultimately weaken them.

So the two ingredients giving toothpaste a basic nature are:

The sequestering agent tetra sodium pyrophosphate (TSPP)which removes calcium and magnesium from the saliva, so they can't deposit on teeth as insoluble deposits called tartar, (calcified plaque). In this respect it acts as a water-softening agent. It won't remove tartar that already exists. Tooth brushes provide the mechanical force and vehicle to remove the deposits physically, to be rinsed out.

TSPP is slightly alkaline, and has a bitter taste, requiring additional flavorings to mask it. Also, additional detergents must be added to keep it in solution. All of these factors can irritate oral membranes and cause sensitivity, with over dosage as well.
