According to Targeting Innovation 4.8 billion people have a mobile phone while only 4.2 billion own a toothbrush.
Given the general health benefits of oral hygiene, today’s invention offers a way to combine these two devices.
Each basic mobile phone (with a protuberant aerial) would come supplied with a rounded crocodile clip on the end.
This would be used to secure a natural brush, such as a thistle, burdock or a clump of wool to the end of the antenna.
Engaging the phone’s vibrate mode would create a primitive but effective buzzing, similar to that of electric toothbrushes, and enabling a more effective tooth cleaning regime.
