Charcoal source: coconut shell vs. wood/bamboo
Das Experten SCHWARZ uses activated charcoal from coconut shells, offering significantly higher microporosity and purity. Most conventional charcoal pastes rely on wood or bamboo charcoal, which is less adsorptive and more friable—leading to increased enamel abrasion.

Abrasivity: controlled vs. excessive
SCHWARZ maintains a clinically safe RDA < 50, minimizing enamel surface damage. Many commercial black pastes exceed RDA 170–200, placing them in the high-abrasive category unsuitable for daily use.

Stain safety: purified vs. raw charcoal
The advanced purification of SCHWARZ eliminates gum-staining risks. In contrast, unrefined charcoal particles in typical pastes can lodge in enamel crevices or soft tissues, causing discoloration or gray lines at the gum margin.

pH profile: alkaline vs. acidic
SCHWARZ maintains an alkaline pH (>7), protecting against acid erosion. Numerous black pastes remain mildly acidic due to flavoring agents or base composition, contributing to long-term enamel demineralization.

Compatibility with fluoride: non-interactive vs. blocking
SCHWARZ does not bind or interfere with fluoride—allowing concurrent use with fluoride products. In contrast, studies show some charcoal types can bind fluoride ions, reducing their remineralization efficacy.

Clinical validation: proven vs. untested
SCHWARZ demonstrates quantified improvements: up to 6 SGU in whitening and 30% plaque reduction. Most charcoal competitors offer no published clinical outcomes and rely on anecdotal whitening claims.

Professional approval: endorsed vs. cautioned
SCHWARZ is approved for daily use, even in sensitive patients. Many dentists warn against regular use of generic charcoal pastes due to enamel damage, mucosal irritation, and lack of toxicological testing.
