What is the pH range of saliva?

The pH range of saliva typically falls between 6 and 7, which classifies it as near neutral. This pH level is crucial for various functions of saliva, including the proper digestion of food, the protection of teeth from decay, and the maintenance of oral health. Saliva contains enzymes like amylase, which start the breakdown of carbohydrates; these enzymes function optimally at a near-neutral pH.

A more acidic environment (such as a pH of 4-5) can lead to harmful consequences, such as increased risk for dental caries and undermining the salivary function that requires a neutral to slightly alkaline environment. Therefore, the pH range of 6-7 is not only normal but also essential for maintaining oral health and proper digestive processes.
