5. Tonsillitis or Throat Infections
Inflamed tonsils, throat infections, or even dental abscesses can make swallowing painful or difficult. When swallowing becomes painful, people unconsciously avoid it, which leads to a build-up of saliva in the mouth and increased drooling during sleep.
Common indicators of tonsillitis or infection include:
Sore throat or difficulty swallowing
Swollen tonsils
Fever
Bad breath
If these symptoms persist along with drooling, it’s advisable to see a doctor for appropriate treatment.

6. Medication Side Effects
Some medications, particularly those affecting the nervous system or used in psychiatric care, can lead to increased saliva production or impair your ability to swallow effectively. For example, medications for Alzheimer’s, schizophrenia, or depression may list drooling as a side effect.
Additionally, medications that cause relaxation or drowsiness can reduce muscle control during sleep, making it harder to keep saliva in the mouth.
Common medications associated with drooling include:
Antipsychotics
Muscle relaxants
Sedatives
Certain Alzheimer’s medications
If you’ve recently started a new medication and noticed a change in your nighttime saliva levels, consult your healthcare provider for alternatives or adjustments.
