Drooling during sleep is common, especially in children and during certain sleep positions. However, if you’re an adult and it happens frequently, suddenly, or in large amounts, it could be your body’s way of signaling an underlying health issue.
While occasional drooling is normal, persistent drooling—especially when accompanied by other symptoms—should not be ignored. Here’s what you need to know.
6 Potential Health Conditions Linked to Frequent Sleep Drooling
6 Potential Health Conditions Linked to Frequent Sleep Drooling1. Oral or Dental Problems
Conditions: Gingivitis, tooth infections, poorly fitting dentures, misaligned teeth.

Signs: Gum redness, tooth pain, bad breath, visible plaque or swelling.
2. Facial Nerve Weakness or Paralysis (e.g., Bell’s Palsy)

Sleep environment productsSigns: Drooping on one side of the face, difficulty closing one eye, asymmetrical smile, slurred speech.
