The saliva pH is around 6.8. It is therefore a slightly acid pH. Saliva lubricates the food bolus and starts the enzymatic extracellular digestion of food. It as well works as a buffer for the mouth pH and it has a significant role of containing IgA antibodies (as well present in tears, colostrum, mother’s milk and in the mucosae of the airways and intestine) which protect the organism against pathogens.
