The short version
A dominant healthy oral bacterium — typically 5-25% of your total oral bacteria — and the basis of the K12 oral probiotic. Produces compounds that inhibit strep throat and a few other respiratory bugs. Higher is generally better.
Do
Maintain regular brushing and flossing without daily antiseptic mouthwashes. S. salivarius dominates a healthy mouth on its own; over-sterilizing depletes it.
Avoid
Daily chlorhexidine or other antiseptic mouthwashes for routine wellness use. They reduce S. salivarius alongside the broader healthy community.
