Question

what happens in tooth decay related to pH?​

Answer 1

$Answer:$

The white enamel coating on our teeth is of insoluble calcium phosphate which is quite hard. It is not affected by water. However, when the pH in the mouth falls below 5.5, the enamel gets corroded. Water will have a direct access to the roots and decay of teeth will occur. In fact, the bacterias present in the mouth breakdown the sugar that we eat in the form of a acids called lactic acid. The formation of these acids causes decrease in pH. It is therefore, advisable to avoid eating sugary foods and also to keep the mouth clean so that sugar and food particles may not be present. The toothpastes contain in some basic ingredients and they help in neutralising the effect of the acids and also in increasing the pH in the mouth.
