Your saliva consist of 98% water and 2% of mucus, electrolytes, antibacterial compounds and enzymes. That magical two percent practically protects your mouth from 95% of the things you throw at it. Producing saliva can account for digesting your food and lubricating your tongue, teeth and soft tissues in your mouth. Not only that, but it also pays a vital role to tasting food. Without saliva, that delicious red velvet cake would be nothing but a soft, luxurious, tasteless cake.
