For how we live.
A self-reported cross-sectional study of 599 residents found sharp deterioration across every measured dimension of oral health during the war — a neglected corner of the humanitarian-health picture.
Cochrane found composite resin restorations had almost double the failure rate in children's permanent teeth. The FDA does not recommend removing intact amalgam fillings from anyone.
The American Heart Association said so in 2012. A 2026 synthesis of 19 systematic reviews found most pooled associations negligible in magnitude, and a genetic analysis found no direct causal path.
Oil pulling and miswak have real short-term data on plaque and gum inflammation. Charcoal dentifrices have almost none, and a third of the products reviewed contained bentonite clay.
A 2026 meta-analysis of nine in vitro studies found a small, outlier-sensitive reduction in enamel microhardness. Every study was done on extracted teeth. The better-evidenced problem is sensitivity.
Two Cochrane reviews found low- to very low-certainty evidence that floss slightly reduces gum inflammation. Neither found a single trial measuring interproximal decay, the thing flossing is sold to prevent.
