⚖️ Thin evidence — read the needle loosely. The score shows which way the studies lean, but there are too few independent, high-quality ones to place it firmly. Expect this to move as better evidence arrives.

What the evidence shows

The classic non-dental xylitol claim: regular xylitol (gum/syrup/lozenge) modestly reduces acute otitis media in children, plausibly by inhibiting *Streptococcus pneumoniae* growth/adhesion. Trials are positive but hampered by the high, frequent dosing needed and poor compliance, so reviews rate it a real-but-modest, impractical preventive rather than a robust one. measured_by:: [[otitis media]]

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
