Hypersalivation (also called ptyalism or sialorrhea) is excessive production of saliva. It has also been defined as increased amount of saliva in the mouth, which may also be caused by decreased clearance of saliva.
Conditions that can cause saliva overproduction include:
- Gastroesophageal reflux disease, in such cases specifically called a water brash, and is characterized by a sour fluid or almost tasteless saliva in the mouth
- Excessive starch intake
- Liver disease
- Serotonin syndrome
- Mouth ulcers[medical citation needed]
- Oral infections
Medications that can cause overproduction of saliva include:

Causes of decreased clearance of saliva include:
- Infections such as tonsillitis, retropharyngeal and peritonsillar abscesses, epiglottitis and mumps.
- Problems with the jaw, e.g., fracture or dislocation
- Radiation therapy
- Neurologic disorders such as myasthenia gravis, Parkinson's disease, multiple system atrophy, rabies, bulbar paralysis, bilateral facial nerve palsy, and hypoglossal nerve palsy.
In the palliative care setting; anticholinergics and similar drugs that would normally reduce the production of saliva causing a dry mouth could be considered for symptom management: scopolamine, atropine, propantheline, hyoscine, amitriptyline, glycopyrrolate.
