Dry mouth or excess saliva can have various causes, ranging in severity from 'minor' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose dry mouth or excess saliva, we could:
|Cigarette Smoke Damage||13%||Unlikely|
|Chemotherapy Side-Effects||0%||Ruled out|
|Drug Side-Effects||0%||Ruled out|
|Iron Deficiency Anemia||0%||Ruled out|
|Tendency Toward Allergic Reactions||0%||Ruled out|
|Alzheimer's Disease||0%||Ruled out|
In general, how plentiful is the saliva in your mouth?
Possible responses:→ My mouth is often very dry
→ My mouth is sometimes a bit dry

Radiation can damage the salivary glands and reduce the amount of saliva produced.
Smoking or chewing tobacco can reduce saliva production.
