Scientists have developed the technology to make it easier for older or disabled people to clean their teeth without any manual effort.
The micro-robots are made of iron oxide nanoparticles that create a chemical reaction in the mouth and kill off plaque. They are directed by a magnetic field and are capable of sweeping away plaque from the broad surfaces of the teeth.
Experiments on both real and fake human teeth found that they can eliminate the biofilms that can lead to cavities and gum disease.
Scientists say the micro-robots can be adapted to fit the shape of individual mouths without damaging gums.
Professor Hyun Koo, from the University of Pennsylvania, said: "This technology is as or more effective as brushing and flossing but doesn't require dexterity. We believe it will disrupt and majorly advance oral healthcare."
Wow clever Boffins...... |
