Corynebacterium is a health-associated bacterial genus that serves as the structural pillar of healthy dental plaque — its filaments are the scaffold around which the rest of the biofilm organizes. It's elevated in cavity-free children and depleted in smokers. Note: Corynebacterium lives mostly in plaque, not saliva, so the salivary number undercounts its true ecological importance.
Maintain regular oral hygiene without over-sterilizing. Brushing twice daily and flossing preserve the plaque environment where Corynebacterium serves its scaffolding role. Avoid daily antiseptic mouthwashes for routine wellness use.
Smoking and daily chlorhexidine/CPC mouthwashes. Both reproducibly deplete Corynebacterium and the broader health-associated supragingival community.
