Anatomy and conditions
Dry mouth
Also called xerostomia
A condition where the mouth does not make enough saliva, raising the risk of cavities.
Dry mouth happens when the salivary glands do not produce enough saliva. Many medicines, some diseases and cancer treatments can cause it. Saliva helps wash away food and neutralize acid, so people with dry mouth are more prone to cavities and discomfort. Dentists may suggest more frequent visits, fluoride and sugar-free gum. Always keep health history and medication lists current, since they often explain this symptom.

He mentioned a new medicine and a dry mouth, so I told the hygienist to review his health history.
