Clean your teeth in six seconds

The brush, which looks like a gum shield covered in bristles, is customised to fit an individual's mouth using scans of their mouth.
By clamping the brush in their mouth and grinding their teeth, it can clean the whole mouth at once and even includes a tongue cleaner.
The technology has been developed by Blizzident, who claim it can clean teeth in just six seconds. They say using their 3D printed brush could save up to 50 hours per year.
However, just one of the brushes costs £250 – although they do say they can last up to a year.
