When exposed to any light source (a fluorescent bathroom light, a plain light bulb, or sunlight), the photosensitive titanium rod inside Soladey-eco converts light into negatively charged electrons (ions). The rod releases these ions, which blend with saliva to attract positive (hydrogen) ions from the acid in the dental plaque. The acid is then neutralised, and plaque is disintegrated - a scientific approach to a cleaner and healthier mouth! Toothpaste is not required as water (saliva) is the active ingredient - oral hygiene now becomes not only natural, but also economical!
IMPORTANT NOTICE: Soleday-eco toothbrushes and replacement heads are not available for sale or shipping to the United States of America.
