Dehydration as a cause of a salty taste in the mouth The most probable cause of a salty taste in the mouth is simply dehydration. The more dehydrated a person is, the more concentrated the chemicals are that are in saliva.
On the other hand the salty taste could come from acid reflux. When acid from the stomach washes up into the esophagus and mouth, which commonly happens at night when you lay down, this can cause irritation to the back of the throat, cough, and a bitter or salty taste in the mouth when you wake up.
