The Bottom Line
Occasional nighttime drooling is common and often caused by your sleeping position or temporary nasal congestion.
However, persistent or excessive drooling may sometimes signal an underlying condition, particularly if it occurs alongside other symptoms such as snoring, difficulty swallowing, or neurological changes.
If you’re concerned, a healthcare professional can help determine the cause and recommend appropriate treatment.
