The structural backbone of healthy dental plaque. C. matruchotii lives mostly on tooth surfaces (not saliva), so saliva tests under-detect it — typical salivary readings are under 1%. Health-associated overall, but it's also the bacterium that drives dental calculus formation. Smoking and antiseptic mouthwash both deplete it.
Maintain regular brushing and flossing, get regular professional cleanings (which manage calculus), and avoid daily antiseptic mouthwash. C. matruchotii is what scaffolds healthy plaque — preserving its niche is the right framing.
