Waking up with bad breath is a common problem, and many individuals have difficulty determining what to do about it. According to an article in the University Daily Kansan, morning breath is caused by the multiplication of anaerobic bacteria in the mouth.
During sleep, the mouth's saliva production drops off precipitously. Since saliva keeps microorganisms at bay, this overnight dry mouth allows oral microbes to flourish. Sleeping with one's mouth open is a particularly common cause of morning breath, the news source said.
Even the healthiest individuals can suffer from morning breath, according to an article in the Journal of Clinical Periodontology. Because of this fact, it can be important to find a mouth rinse that addresses both the cause of morning halitosis and the smell itself.
Unrestrained bacterial growth leads to the production of volatile sulfur compounds, which are the substances that give bad breath its scent. Effective mouthwashes should attack microorganisms and the byproducts of their digestion.
Using a specialty breath freshening product that neutralizes bacteria and sulfurous odor compounds can keep the mouth smelling clean and put oral microbes in their place.
