Blizzident 'six-second toothbrush' created by dentists

Blizzident uses the same scans dentists use to fit braces and an extremely precise 3D printer to create a brush tailored for each individual customer. Each brush contains about 400 soft bristles and requires the wearer to grind their teeth in order to clean. via Pocket http://www.bbc.co.uk/news/technology-24362939
