What percentage of saliva is water?

Explanation:
Saliva is made mostly of water, about 99% of its composition. That high water content acts as the solvent and medium that keeps the mouth hydrated, helps dissolve tastants, and facilitates swallowing and digestion. The remaining roughly 1% includes organic and inorganic components such as mucins for lubrication and viscosity, electrolytes like bicarbonate and minerals, enzymes in small amounts, and antimicrobial proteins. This small solid portion provides protection, buffering, remineralization potential, and antimicrobial defense, while the vast majority being water keeps everything flowing and functional.
