Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Streptococcus oralis is a species of commensal bacteria commonly found in the human oral cavity. Its use to support the “Teeth” body system is scientifically justified, though the evidence is moderate. S. oralis is part of the normal oral microbiota and plays a role in maintaining oral health by competing with pathogenic organisms, such as Streptococcus mutans, which is implicated in dental caries (tooth decay). Several in vitro and observational studies suggest that S. oralis may help inhibit the colonization and growth of cariogenic and periodontopathogenic bacteria through the production of bacteriocins and by occupying ecological niches, thus contributing to oral microbial balance.

However, evidence for the direct use of S. oralis as a defined probiotic for dental health is limited compared to other oral probiotic species such as Streptococcus salivarius or Lactobacillus reuteri. There are few clinical trials, and most of the supportive data come from studies analyzing the composition of healthy vs. diseased oral microbiomes. Nonetheless, S. oralis is often present in greater abundance in healthy subjects, hinting at a protective role. In summary, while S. oralis is scientifically recognized as beneficial for oral ecology and potentially for dental health, more clinical intervention studies are needed to solidify its use as a targeted supplement for supporting the teeth body system.
