Saliva and your mouth chewing are at a warm temperature. The water you drink causes the “hardening” by being cold in comparison. Try the same with hot water.

Temperature? Water is usually colder than your own spit. I think that has something to do with it.

The water you drink is almost always cooler than body temperature. The cold makes it hard, not the wet.
