Solution

The correct option is B False
Tooth Decay
Enamel and dentine decay over time as a result of tooth decay.
It begins when bacteria produce acids as a result of sugars softening or demineralizing the mineral.
The oxidation of sugar and food particles in the mouth after meals bacteria in the mouth create acids.
When the pH of the mouth falls below 5.5, tooth decay occurs.
Therefore, tooth decay is caused by acid, not a base. Hence, the above statement is false.
