Green tea consumption significantly prevents tooth decay
the verdict
SUPPORTED
the evidence backs this
confidence 89/100
Multiple in vitro, in vivo, and systematic reviews support the claim that green tea consumption and its active catechins (such as EGCG) help prevent tooth decay by inhibiting the growth, biofilm formation, and acid production of caries-associated bacteria like Streptococcus mutans.
Paper [0] demonstrates that EGCG from green tea inhibits Streptococcus mutans biofilm formation by suppressing gtf genes.
