}} Drooling (or "ptyalism") is caused by saliva flowing outside the mouth. Drooling is generally caused by excess production of saliva, inability to retain saliva within the mouth, or problems with swallowing.
Some people with drooling problems are at increased risk of inhaling saliva, food, or fluids into the lungs. However, this is unlikely to cause harm, unless the body's normal reflex mechanisms (such as gagging and coughing) are also impaired.
Common causes
Isolated drooling in infants and toddlers is normal and is unlikely to be a sign of either disease or complications. It may be associated with teething. Drooling in infants and young children may be exacerbated by upper respiratory infections and nasal allergies.
Drooling associated with fever or trouble swallowing may be a sign of a more serious disease including:
- Retropharyngeal abscess
- Peritonsillar abscess
- Tonsilitis
- Mononucleosis
- Strep throat
- Parkinson's_disease
A sudden onset of drooling may indicate poisoning (especially by pesticides) or reaction to snake or insect venom. Some medications can cause drooling as well. Some neurological problems also cause drooling. Excess Capsaicin can cause drooling as well, an example being the ingestion of particularly high Scoville Unit chili peppers.
Home care
Care for drooling due to teething includes good oral hygiene. Popsicles or other cold objects (e.g., frozen bagels) may be helpful. Care must be taken to avoid choking when a child uses any of these objects.
