A common oral commensal carried by about two-thirds of healthy adults. On the HACEK list of bacteria that can rarely cause heart valve infections in people with damaged valves, but routine salivary detection in healthy adults is not a clinical concern. No periodontal disease association.
No specific intervention needed. C. hominis is part of the normal healthy oral community in most adults.
Daily antiseptic mouthwashes would deplete it alongside other gram-negative commensals — but this isn't a reason to use them, since lowering C. hominis carries no known health benefit in healthy adults.
