During regular check-ups, dental and medical professionals take measurements to assess your health, like your height, weight, and blood pressure, which can help indicate information about your health. There’s another measurement, however, that can also provide insight: your saliva pH. Here, we’ll look at why your saliva pH is important and how it affects your oral health.
The pH scale measures a substance's acidity or alkalinity. The scale ranges from 0 to 14, with 7 representing neutrality. The lower end of the scale is acidic, and the higher end of the scale is alkaline. What is the pH of saliva? According to an article in the Hindawi journal, the normal pH of saliva is between 6.7 and 7.4, making it relatively neutral. But if this level reaches below this range, meaning if your saliva pH is more acidic, it could reflect an issue or abnormality with your oral health.
