Bad breath when you wake up

In the morning, when you wake up, you feel that you have bad breath. Well, the breath is bad because all night long, your mouth has been dry. When you sleep, the body has a natural tendency to slow your body's saliva flow. This type of bad breath "occurs" when persons like lawayers or teachers talk very much, and then they do not talk at all for a long period of time.

Saliva naturally washes, dillutes and kills the bacterias in your mouth. When there is no more saliva, you can imagine yourself what happens. The washing and bacteria killing mecanism doesn't work no more.

Xerostomia is also a cause of having a dry mouth. Xerostomia can be a side effect of the medication a person is taking. Antihistamines (allergy and cold medications), antidepressants, blood pressure agents, diuretics, narcotics, or anti-anxiety medications are each known to produce xerostomia.
