Why saliva matters beyond thirst
Saliva helps moisten food, supports swallowing and protects teeth and the mouth. Wanting a drink and having a persistently dry or sticky mouth are not interchangeable descriptions. Drinking and then feeling less dry does not identify the cause, or establish how much saliva is produced.
A feeling is different from a measurement
Assurance Maladie explains that perceived dryness and measured low saliva do not always coincide. “My mouth becomes sticky during long conversations” is a fictional report of a situation, not a saliva test. A dentist or clinician can assess the mouth and decide what measurements, if any, are appropriate.
Bring the actual question to dental or medical care
NIDCR lists medicines and health conditions among possible causes. Explain whether dryness predates quitting, whether it persists, and whether eating, speaking or teeth are affected. Bring medicine questions to a pharmacist or clinician without changing the medicine yourself. A generic water target or a smoking experiment cannot answer those questions.
