Alcohol

One common cause of temporary bad breath is the consumption of alcohol. While most of us like to have a glass of some fine red wine in good company or maybe a beer or two while watching sports, this will have its effect on your mouth odor and can cause bad breath.

So why is that?
Alcohol affects your breath in two ways. First of all, most alcoholic beverages themselves cause an odor because of their taste. We’ve all experienced that our breath changes after a couple of pints or maybe some glasses of wine. Most liquors also affect your oral odor.

Another reason is that alcohol dehydrates you. “Alcohol is a diuretic. This means it encourages the body to lose more water than it takes on by halting the production of the body’s anti-diuretic hormone. This means you feel the need to pee excessively, thus speeding up the loss of fluid from the body that leads to dehydration”, as it is said on TheSite.org.

Not only does this mean that it can cause quite a hangover if you don’t drink enough water in-between your drinks. It also causes your mouth to become dry. This again leads to the production of anaerobic bacteria, which are the number one cause of bad breath.
