What is the pH of saliva?
Saliva normally has a pH range of 6.2 to 7.6. This range is essential for maintaining oral health and supporting digestive processes.
A pH level around 7 is considered neutral, which means the saliva is neither acidic nor alkaline. Values below 7 indicate acidity, which can be influenced by factors such as diet, oral hygiene, and certain health conditions. For example, a diet high in sugar or acidic foods can lower saliva pH, potentially leading to dental issues like tooth erosion or cavities.
Conversely, saliva with a pH above 7 is alkaline, which helps neutralize acids produced by bacteria in the mouth and contributes to balancing the pH in the digestive system. Alkaline saliva can be influenced by factors like a diet high in fruits and vegetables or by certain medications.
Saliva’s pH can fluctuate throughout the day based on factors such as eating, drinking, and even stress. Regularly monitoring saliva pH can provide insights into oral and overall health. If you notice persistent abnormalities in your saliva pH, it’s a good idea to consult with a healthcare provider for further evaluation and advice.
