"3D-Printed Toothbrush Cleans All Your Teeth in 6 Seconds"




Blizzident, a new 3D-printed toothbrush, looks like a mouthguard lined with 600 bristles. You bite down into the 3D replication of your mouth and grind your teeth on the bristles, which cleans all of your teeth simultaneously.
 

 
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 dense clusters of bristles in the brush are angled to align along a person’s gum line and touch the surface of each tooth at a 45 degree angle.

A group of dentists and engineers who are based in Spain, claim their new design could be ideal for those who feel traditional tooth brushes are eating into their day.

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.

Describing how the brush works, “You simply bite and release quickly 10 to 15 times. This creates little vibrating, jiggling and slightly circling movements. Grinding left-right and backward-forwards, while your teeth are closed… additionally cleans the top surfaces of your molars.”

“Opening your mouth causes the gum line-bristles to additionally wipe dirt out.”

“Because you are brushing all your teeth at the same time, you are brushing extremely quickly.

“You brush all the difficult-to-reach and interdental regions without even having to think about it.” The brushes are created using scans and 3D models of the patient’s mouth.

These are then used to create a brush that is then printed out of soft plastic using a 3D printer with the inner surfaces covered in thousands of hair-like bristles.

It also contains slots where floss can be fixed to clean in between teeth, the company claims. However, the company has still to publish any clinical trials to show how its new brush compares to other tooth brushes.
