ph of saliva is

The pH of saliva normally ranges from about 6.2 to 7.6 , which is slightly acidic to neutral. The average pH value is around 6.7 to 7.0 , with a healthy mouth typically maintaining salivary pH near neutrality. Variations can occur depending on diet, hydration, oral health, and bacterial activity in the mouth. A saliva pH below 7 indicates acidity, which can increase the risk of dental decay and other oral diseases, while a pH above 7 indicates alkalinity, though this condition is rarer. Maintaining balanced saliva pH is important for protecting teeth and gums and for oral health overall.
