Oral-B has released a new “smart toothbrush” that can detect which areas of the mouth are being neglected.
The device, called the “Genius” toothbrush, pairs with a smartphone app which users must stand in front of while cleaning their teeth.
The BBC”s Chris Foxx asked Oral-B brand manager Ale Apostoli whether that might be inconvenient.
