Answer:
PH: Potential of Hydrogen
PH stands for Potential of Hydrogen. It refers to the hydrogen ion concentration in a solution. It is the measure of the acidity or alkalinity of a solution. The PH value ranges from 0 to 14 on a pH scale.
Explanation:
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.
