Ion5 Technical Info

When exposed to any light source (a fluorescent bathroom light, a plain light bulb, or sunlight), the solar panel charges the patented titanium dioxide semiconductor rod inside Ion5 converting 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 neutralized and plaque is disintegrated. After wetting the bristles and semiconductor with water, brush your teeth lightly and thoroughly in the same way as with an ordinary tooth brush. You may if you wish use a small amount of your preferred toothpaste on the bristles although this is not necessary with Ion5. Make certain there is always an adequate light source – natural or artificial on the solar panel as this is needed for activation.

Ion5 Ionic Toothbrush Soladey Australia

 The human and canine mouths natural defences produce reactive oxygen species to kill microbes and to disintegrate their waste toxins. The Ion5 does the same thing. This toothbrush functions in a unique scientific way by virtue of ‘a photo electro chemical system leading to the efficient mineralisation of the lactic acid in water into carbon dioxide, suggesting this system can be practically applied for the safe removal of lactic acid in the human buccal cavity.’ (1)

Soladey was invented in Japan by Dr. Yoshinori Nakagawa. The name originates from the words ‘Solar’ and ‘Dental’. Dr. Nakagawa knew that negative ions could be generated from titanium when this metal was exposed to light and water. As with other industrial applications such as water purification and air filtration, ionic power is not a recent discovery.


Clinical studies show that titanium exposed to a light source has an excellent bacterical capacity against Streptococcus mutans., a micro-organism found in the mouth that is particularly related to dental caries.

In Japan a clinical report on titanium toothbrushes found that dental plaque removal was significant during the early phase of plaque formation and concluded that the brush was effective in the control of plaque.

Another Japanese study concluded that improvements in gingivitis and oral hygiene can be expected by using a toothbrush equipped with a titanium semiconductor.

A clinical study conducted at a Canadian College of Dentistry indicated that removal of plaque - from buccal surfaces especially – was more apparent using the ionic brush than it was using the control brush without semiconductor.
