Question

Decaying of teeth due to change in pH​

Answer 1

Answer:

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. Since plaque coats the teeth, saliva can not reach the tooth layer to neutralize the acid.
