Dental Hygienist Inita Čeire advices about pH level into mouth and how the changes in pH level can affect your teeth and oral health.

"You would think if the cause of tooth decay was the acidic condition of the mouth, then the dentist could simply offer a "basic" solution to rinse with a few times a day and cavities would stop. It isn't as simple as this.

pH is the natural oral microflora and its level should be from 5.5 to 7. Then it is a normal oral environment, the pH within this range the balance of the microflora of the mouth. If your mouth has a normal pH environment that  it  help avoid gum disease and holes in the teeth and maintains good oral hygiene."
