10 Causes of Bad Breath

Cause #3: Xerostomia
Xerostomia or dry mouth can be a symptom of several medical conditions. The production and constant flow of saliva in your mouth are necessary to keep it clean. Saliva can wash away food particles and limit the growth of oral bacteria. However, if your mouth is constantly dry, bacteria can proliferate easily, causing halitosis.
Causes of dry mouth include medications (i.e. antihistamines), cancer therapies, medical conditions (i.e. Sjogren’s syndrome), and tobacco use.
