Frequent Snacking and Oral pH

Did you know that your mouth goes through a change in pH or acidity throughout the day and night? 

Not only does an acidic pH create a friendly environment for bacteria to grow and expand in number, it also softens the outer surface of your tooth called enamel.

When you eat something, the pH in your mouth drops from neutral to an acidic pH. This is normal and natural. The saliva in our mouth contains factors, called bicarbonate, which can bring this pH back to neutral, but it takes up to a few hours. So eating often keeps the mouth an acidic environment without giving it a chance to come back to neutral. Therefore, your Dentist will recommend you to limit the frequency of snacking to help prevent dental diseases like cavities and gum disease.
