Question

How does PH change cause tooth decay? How it is prevented ​

Answer 1

Explanation:

Bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth after eating. Tooth decay starts when the pH of the mouth is lower than 5.5. Using toothpastes, which are generally basic, for cleaning the teeth can neutralise the excess acid and prevent tooth decay

Answer 2

Answer:

PH change cause tooth decay :

Tooth decay starts when the mouth's pH is below 5.5. In addition to food particles, masses of bacterial cells bind to the teeth to form dental plaque. Since plaque coats the teeth, saliva can not reach the tooth layer to neutralize the acid.

It can be prevented :

Using toothpastes, which are generally basic, for cleaning the teeth can neutralise the excess acid and prevent tooth decay. The best way to prevent this is to clean the mouth after eating food.
