The pH of saliva typically ranges from 6.2 to 7.6, with an average pH of 6.7. This makes saliva slightly acidic to neutral. The pH of saliva can fluctuate depending on factors such as diet, medications, and oral health.
For example, consuming acidic beverages can temporarily lower the pH of saliva, making it more acidic. This can contribute to tooth decay and other oral health problems.
Maintaining a healthy salivary pH is crucial for oral health. Saliva helps to neutralize acids in the mouth, buffer against pH changes, and remineralize tooth enamel.
