The Amabrush, which looks like a bristly mouth guard, can dispense toothpaste and vibrates to clean every tooth, according to its creators. Customers can preorder the device now for $90, with worldwide shipping starting in December.

To use the device, customers merely put the toothbrush in their mouth and press a button to start the cleaning process. The system uses bespoke toothpaste capsules which cost $3.40 and last around one month.
