The smartphone app will tell the user when to move to a different part of the mouth and warn if they are brushing too hard

Smart toothbrush brings dentists into the bathroom

A smartphone-connected toothbrush will give personalised advice to help people improve their brushing.

The toothbrush, to be sold under Procter & Gamble's (P&G) Oral-B brand from June, has a Bluetooth 4.0 link to a smartphone app that can be programmed with the help of a dentist. It will advise users to, for example, pay more attention to any areas of the mouth being neglected, P&G said.

The toothbrush will be unveiled at the phone industry's annual Mobile World Congress (MWC) in Barcelona next week.

"The app provides real-time guidance," Michael Cohen-Dumani, global associate director for Oral-B, told Reuters.

"Dentists always tell us 'people do a great job in the week before they come to visit us and in the week after they visit us. But nothing can hide the fact that when we look inside the mouth we can see all the areas they miss'."

Professionals helped develop the app as a tool to manage their patients' behaviour between visits, Cohen-Dumani said. The app displays brushing progress in real-time, telling the user when to move to a different part of the mouth and warning if they are brushing too hard, he said.

"It will guide you in terms of how to brush, and you will be able to fully personalise the brushing routine for you," Cohen-Dumani said.

In tests, the app had extended average brushing times from less than a minute for a manual toothbrush to two minutes and 16 seconds, he said.

The device will be at the top end of the Oral-B electric toothbrush range, with a recommended retail price of £199 in Britain and €219 in Europe.
