What is the importance of water content of the body?

1.1. It helps create saliva

Water is a main component of saliva. Saliva also includes small amounts of electrolytes, mucus, and enzymes. It’s essential for breaking down solid food and keeping your mouth healthy. Your body generally produces enough saliva with regular fluid intake. However, your saliva production may decrease as a result of age or certain medications or therapies. If your mouth is drier than usual and increasing your water intake isn’t helping, see your doctor.
