Question

how does the pH level change due to tooth decay?

Answer 1

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.

Answer 2

Explanation:

One way tooth decay can occur is when the pH level in the mouth begins to fall below 5.5. The neutral pH level is 7.0, so this will drop when acidic foods and drinks are consumed. When the mouth is exposed to long periods of low pH, it allows cavity causing bacteria to grow and develop
