Question

how ph change in mouth lead to tooth decay? ​

Answer 1

$\large\fbox\red{Answer}$

Just like the rest of your body, your mouth needs a balanced pH. The pH level of your saliva can drop below 5.5 when you're drinking acidic beverages. When this happens, the acids in your mouth start to demineralize (break down) tooth enamel. If the tooth enamel becomes too thin, the dentin is exposed.

Answer 2

Answer:

Bacteria in the mouth create acids after eating through the oxidation of sugar and food particles in the mouth. 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.
