Every time we brush our teeth, we rinse the brush under the tap and leave it until the next time it’s needed. Without sterilizing it, the brush accumulates bacteria, which can cause microbial infections each time it’s used (I know, this sounds like an advert). If this is something that bothers you, Rakuten Japan has produced the W072470, to sterilize your toothbrush automatically using ultraviolet radiation. It only takes 4 minutes, and the lamp turns itself off automatically. The W072470 costs 5,250 yen ($44/£23).
