Salivation or drooling is when saliva unintentionally flows out of the mouth often because of an overproduction of saliva by the salivary glands. It is normal in infants, particularly when during teething, but may also occur in adults with certain neurological conditions, such as cerebral palsy, Parkinson’s disease, or amyotrophic lateral sclerosis.

In many cases, treatment of salivation is not necessary. Possible treatment options include speech and occupational therapy, dental devices, Botox injections, surgery, and medication. Drug classes used to help reduce saliva production include anticholinergics.
