Question

Did you observe any change in pH after eating ? What caused the change ?

Answer 1

Yes, there is a change in the pH of saliva after eating. The normal pH of saliva is 6.2 to 7.6. but if we drink beverages the pH drop below 5.5 which starts to demineralize tooth enamel, if the tooth enamel becomes too thin the dentin is exposed. This can lead to discomfort when consuming hot, cold or sugary drinks. After the wake up in the morning, the pH of the mouth is low because of the presence of the bacteria which break down the carbohydrates you consume, releasing lactic acid, butyric acid, and aspartic acid.
