The KO-SHU Baking Soda Smooth Toothpaste is a natural, stain-targeting toothpaste formulated to gently lift yellow discoloration caused by tannins (e.g., from tea, coffee, or smoking) without damaging enamel. Its core active—baking soda (sodium bicarbonate)—works through dual action:
  • Protein-degrading power: Breaks down stubborn surface stains bound to dental pellicle
  • Mild abrasive texture: Polishes teeth smoothly with fine, non-scratching particles

Unlike conventional whitening pastes that rely on harsh peroxides or silica, this formula uses only food-safe, naturally derived ingredients:
  • 100% plant-based soap base (no SLS or synthetic detergents)
  • Natural sea salt to help tighten gums and support oral balance
  • Peppermint essential oil for refreshing, long-lasting breath—no artificial fragrance

The paste has a smooth, creamy consistency that foams lightly and rinses cleanly. It leaves teeth feeling polished and refreshed, with visible brightness after consistent use—ideal for daily care or targeted stain removal.

How to Use:
Brush twice daily with a soft-bristled toothbrush. For best results on yellow stains, use consistently for 2–4 weeks. Safe for adults and teens; not recommended for children under 6 due to swallowing risk.

Note: This is a cosmetic toothpaste—not a medical whitening agent. Results vary by stain type and oral hygiene habits. Discontinue if gum sensitivity occurs.

Developed in Japan with a focus on transparency and safety, KO-SHU delivers effective, gentle care you can trust—because what goes in your mouth matters.
