Dental Healthcare, How Alcohol Can Cause Bad Breath
Drinks with alcohol will tend to dry out your mouth. Having a dry mouth aids the anaerobic bacteria that causes bad breath. Anaerobic bacteria are killed when exposed to oxygen which is found in your saliva. So a dry mouth will not have as much oxygen that kills bacteria.
Unfortunately alcohol is also found in many mouthwashes. Therefore make sure to use a mouthwash that does not contain alcohol so it does not dry out your mouth
