AOR’s Breath Biotics™ formula with BLIS™ K12 contains a patented strain of the probiotic Streptococcus salivarius K12, which helps ensure healthy oral microflora, therefore reducing the bacteria that cause both bad breath and sore throat. An estimated one out of every four individuals experience halitosis regularly. There are several issues that may trigger bad breath with poor oral hygiene and the buildup of bacteria being at the top of the list. But bad breath may be the result of a number of other factors as well such as exposure to malodorous foods, an infection, or a deeper, more systemic medical concern.

Breath odor itself relates to volatile compounds with a high sulfur content that are produced by gram-negative bacteria on the tongue or between and around teeth. Halitosis can be transient (from sulfuric foods, tobacco products, or dry mouth) or it can persist. Cleaning the tongue, by brushing or with mouthwashes, may remove some of the offensive compounds (food remnants, dead cells, etc.) that the bacteria feed on. It may also clear away the bacteria themselves or help mask the odor for a period of time. Treatment of the underlying cause, however, is ultimately the best practice. When combating halitosis, the first step should be determining whether the oral microbiota are healthy.*

*Persistent halitosis may indicate a more serious condition and it is best to consult with a health care provider for a course of treatment.
