Answer 2

Explanation:

We know that our tooth are made up of calcium and our stomach contain HCl , on the other side marbles are calcium carbonate and when we add  dilute HCl to the calcium carbonate it form calcium chloride, water, and carbon dioxide as product , which indicates that tooth get decay by the presence of acid.

CaCO3  +  HCl   →   CaCl  +  CO2 + H2O

When the bits of food present in our teeth for a long time saliva release acid to dissolve the food particles, if this acid stay in our mouth for long it will slowly decay our teeth.
