Streptococcus oralis is a commensal bacterium naturally found in the human oral cavity and is a member of the viridans group streptococci. Recent research has explored the use of certain beneficial oral streptococci, including S. oralis, as potential probiotics to support oral health and prevent or reduce tooth decay (dental caries). The rationale is that these commensals can inhibit the growth of cariogenic bacteria such as Streptococcus mutans through competitive exclusion, production of hydrogen peroxide, and modulation of the oral environment.
Several studies have shown that S. oralis and related species can colonize dental surfaces and may help maintain a balanced oral microbiome. In vitro experiments demonstrate that S. oralis can suppress the growth of S. mutans and reduce acid production, a key driver of tooth demineralization and decay. Some pilot clinical studies and probiotic formulations containing S. oralis (often in combination with other species such as S. uberis and S. rattus) have shown promise in reducing markers of cariogenic bacteria and supporting oral health.
However, large-scale, long-term clinical trials in humans are still limited, and no standard probiotic therapy using S. oralis has yet been established for caries prevention. Thus, while there is a scientific basis and encouraging early evidence, the overall strength of evidence is moderate at this time.
