Drooling, or slobbering, is the flow of saliva outside the mouth. Drooling can be caused by excess production of saliva, inability to retain saliva within the mouth (incontinence of saliva), or problems with swallowing (dysphagia or odynophagia).
There are some frequent and harmless cases of drooling – for instance, a numbed mouth from either benzocaine, or when going to the dentist's office.
Isolated drooling in healthy infants and toddlers is normal and may be associated with teething. It is unlikely to be a sign of disease or complications. Drooling in infants and young children may be exacerbated by upper respiratory infections and nasal allergies.
Some people with drooling problems are at increased risk of inhaling saliva, food, or fluids into the lungs, especially if drooling is secondary to a neurological problem. However, if the body's normal reflex mechanisms (such as gagging and coughing) are not impaired, this is not life-threatening.
