Hello Epic Whitening Activated Charcoal Fluoride-Free Toothpaste - SLS-Free Natural Formula

Activated charcoal works through adsorption—not absorption. Its porous surface has a slight negative charge that attracts positively-charged molecules like tannins (from coffee, tea, wine) and bacteria. These bind to the charcoal and are removed when you spit. It's a gentle mechanical process, unlike chemical bleaching that penetrates enamel with hydrogen peroxide.

Hello's charcoal formula is designed for daily use with appropriate abrasivity. However, the ADA notes that charcoal toothpaste may be more abrasive than some conventional options. If you have sensitive teeth, weakened enamel, or dental work (veneers, crowns), consult your dentist. For most users, daily use is safe when brushing with proper technique.

No! Despite its dramatic black appearance, Hello Charcoal rinses completely clean. It won't stain your sink, towels, or toothbrush bristles. The activated charcoal is finely milled and suspended in a water-soluble base that washes away easily. Many users are surprised how non-messy the experience is.

Chemical whitening (hydrogen peroxide, carbamide peroxide) works by penetrating enamel to bleach internal tooth structure. While effective, it commonly causes sensitivity and may weaken enamel with repeated use. It can also irritate gums. Charcoal whitening only addresses surface stains and doesn't penetrate enamel, making it gentler for regular use.

Surface stain removal can be noticeable within 1-2 weeks of consistent use. However, charcoal only removes extrinsic (surface) stains—it won't change the natural color of your teeth or address intrinsic discoloration. For maximum results, use twice daily for 2-3 minutes per brushing, and consider reducing consumption of staining beverages.
