The Philips Sonicare DiamondClean Toothbrush charges via rinsing glass
Oral hygiene has come a long way from the twigs, bird feathers and animal bones our ancestors used to clean their teeth. The first recorded toothbrush in history consisting of a twig with a frayed end called a chew stick dates back to 3,000 BC but toothbrushes have since evolved to include electric toothbrushes that move the brush head more rapidly than our puny wrists can manage. Such devices of course require charging, which usually means a charge station taking up valuable real estate on the bathroom counter alongside a rinsing glass. Now Philips has released a toothbrush that charges when placed in a glass that can still be used to rinse your mouth after brushing.
