What Is Saliva?
Saliva is 99% water and organic components (proteins and enzymes) and inorganic components (calcium, fluoride, phosphate, carbonate, sodium, potassium, chloride, and others). Additionally, saliva contains serous transudate, gingival crevice secretion (gingival fluid), nasal and throat secretions, desquamated epithelial cells, leukocytes (blood cells – white blood cells – responsible for the body’s immunity), microorganisms, and food residues.
