Ingredient
Hydrated Silica
Scout's take
Standard gentle abrasive that physically scrubs plaque off enamel. Inert at the molecular level, but Lead Safe Mama 2025 testing implicates the silica feedstock as one of two likely routes of the 493 ppb lead, 19 ppb mercury, and 6 ppb arsenic contamination — silica is mined and refined and can carry trace heavy metals depending on the source.
