AOR Breath Biotics is a patented oral probiotic strain of Streptococcus salivarius K12 which helps fight bacteria which cause bad breath or halitosis. It promotes a healthy oral microbiome by increasing the good bacteria in our mouths, which acts as our first line of defence against infection. Comes in a natural mint flavour.
