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 the likely route of the 100 ppb lead and 8 ppb mercury contamination — silica is mined and refined and can carry trace heavy metals depending on the source.
