Answer 1

Answer:

The pH scale goes from 1 to 14, with a pH of 1 being the most acidic, and 14 being the most alkaline. A pH of 7 is neutral – the pH of pure water is very close to 7. At a pH of 5.5 the teeth begin to demineralize, putting them at risk for cavities.

Hey mate! The answer is tooth decay can occur when the pH level in the mouth is 5.5 as the neutral level of mouth is 7.0.
