Apply an appropriate amount of toothpaste, approximately 1cm, to your toothbrush and brush thoroughly. Brush especially carefully before bedtime.
After use, close the toothpaste cap tightly and store in a cool place. Do not swallow, and keep out of reach of infants and young children. If a rash or another unusual reaction occurs, discontinue use and consult a doctor.
Rinse the toothbrush with water after use and store in a well-ventilated place. Do not soak it in chlorine-based disinfectants, bleach, or boiling water. Avoid rubbing the crystal or subjecting it to strong impacts. If the crystal comes off, discard the toothbrush immediately to avoid accidental swallowing by children. Take care not to scratch skin or other objects with the crystal surface.
