A Revolution in Toothbrush Design

Gizmodo: “Researchers at the Fraunhofer Institute have developed a virtual brushing simulator that promises to revolutionize how toothbrushes are designed and tested … The size, shape, and elasticity of a toothbrush’s bristles can be precisely modified and tested in the simulator, but so can the size, shape, and quantity of the abrasive particles in a toothpaste.”

“Highly controlled experiments can be conducted in the simulator allowing toothbrush designers to almost instantly determine how effective a new bristle design is at removing dirt while still preserving tooth enamel … So in the future when a commercial for a new toothbrush promises it to be effective at battling plaque and gingivitis, hopefully its creators will be able to show the simulated results backing up their claims before you make the upgrade.”
