Streptococcus oralis subsp. dentisani is a subspecies of the Streptococcus oralis group, which is part of the normal human oral microbiota. This subspecies has garnered attention for its potential probiotic properties, particularly in promoting oral health. Unlike some other oral bacteria that contribute to dental caries and periodontal diseases, Streptococcus oralis subsp. dentisani is associated with beneficial effects, such as inhibiting the growth of pathogenic bacteria and supporting the maintenance of a healthy oral microbiome.

Research into Streptococcus oralis subsp. dentisani is ongoing, with studies exploring its ability to prevent cavities and other oral infections by competing with harmful bacteria and possibly modulating the host immune response. This makes it a promising candidate for inclusion in oral care products aimed at enhancing dental health naturally.
