Private investigator reveals how toothbrush led woman to discover husband's affair

A woman discovered that her husband was cheating on her not through texts or phone logs but with the help of his toothbrush.

Private investigator Paul Jones from ARF Investigators told Mirror how a smart electric toothbrush app, which was originally installed to monitor the couple’s children’s brushing habits, ended up exposing a secret affair.

The app tracked every family member’s brushing sessions, and over time, a strange pattern emerged.

“Quite often we won’t catch our partner in the act so to speak, it often comes in small clues such as spending more time at work, picking up a new hobby or taking more pride in their appearance, but one thing many of us may miss is for every action we take, often data is being tracked,” Jones told Mirror.

As far as this couple is concerned, the clue was in the data provided by the app: brushing activity logged late on Friday mornings when Jones’s client’s husband was supposedly at work.

“The client couldn’t work out why the app was showing that the husband was brushing his teeth later in the morning on a Friday when he should have been in work,” Jones added.

The regularity of the logs, however, helped her understand everything clearly. The woman eventually learnt her husband hadn’t worked on Fridays for three months.

“And in that time he had started an affair with a work colleague and used to have her over the family home on a Friday when the wife and kids were out of the house,” Jones said.

As technology continues to shape daily lives, Paul Jones added, “The data doesn’t lie. It’s timestamped, often location-based, and emotionless. When a device says someone brushed their teeth at 10:48 am when they were supposed to start work at 9 am that’s very hard to explain away.”
