A UK woman started suspecting her husband of cheating after checking the data on her electric toothbrush companion app and noticing that they were brushing at odd times of the day.

Paul Jones, a British private investigator with over a decade of experience, recently recounted one of his most unusual cases. Catching a cheating partner in the act is rare, but rarer still is catching them cheating with the help of an electric toothbrush. And yet, it can happen! One of Jones’ clients, a married mother-of-two who was trying to improve her children’s brushing habits by monitoring their electronic toothbrush use via a smartphone app, noticed that the brush was being used at strange times of the day when her kids were supposed to be at school and her husband at work. After making sure her kids were indeed at school, she confronted her husband, who claimed to have been away at work all day.
