Oral care in emergency

When evacuating to a shelter due to disasters, oral care tends to be neglected because water is precious, but tooth decay can cause serious life-threatening diseases. SOLADEY is a toothbrush that can brush your teeth using light in an evacuation life.

It has a photocatalytic(TiO2 titanium oxide) semiconductor, and it reacts with light and water to generate negative electrons(e-), which can remove plaque. That means you can brush your teeth well without using toothpaste and save water. It also has a solar panel that, when exposed to light, automatically generates the electrons needed to remove plaque. Of course it is waterproof. This is a replaceable brush, you can just replace the brush part and share it with your family, which also reduces the amount of garbage.

Recently, Sei Shop, which sells this product, has released a "survival set" that includes replacement brushes for family members and a pouch. It includes one toothbrush grip part and four replacement brushes and the price is 3850 yen (including tax) . It is a good idea to put it in a disaster prevention bag in case of emergency.
