3D printing has allowed high-tech corporations to create cheap prototypes, NASA to create parts for the International space station on the fly and, now, to the creation of a 3D-printed toothbrush.

While admittedly not as sexy as say a 3D-printed exoskeleton or motor scooter, the new toothbrush from Blizzident is innovative. And, it does remove the drudgery of standing in front of a mirror brushing back and forth for two minutes, as the American Dental Association recommends.

Dense bristles, short brushing

Looking a bit like a set of dentures for the mouth of Spiderman villain Venom, the new toothbrush packs 400 bristles into a mold of a person's mouth. By biting down on the mouthpiece, and grinding on it, the 45-degree angled bristles can provide a spotless set of pearly whites in seconds.

Because there are roughly ten times more bristles than in a typical toothbrush, the Blizzident brush lasts as long as a year, according to the company.

"The bristles are tailored and positioned on every single tooth in a way so they are brushing with the " Modified Bass and Fones" techniques simply by biting and grinding for a few seconds," Blizzident explained. "Modified 'Bass"' and 'Fones' techniques are recommended by dentists and prophylaxis assistants worldwide."

By biting and grinding on the Blizzident's 400 tailored bristles, the toothbrush is able to clean your teeth within six seconds.

Along with the 45-degree angled bristles, there are interdental bristles that get between teeth, performing the job of dental floss. The Blizzident also comes with slits where dental floss can be inserted in just the right position to clean between teeth, the company said.

The handle of the Blizzident serves as a container for a dental floss role.

Scan for a perfect 3D fit

The toothbrush is tailored to a person's mouth through either a dental impression or a scan of your teeth performed by a dentist.

According to Blizzident, any dentist can direct scan or make an impression of your teeth for between $75 and $200. The digital 3D model can then be uploaded to Blizzident's site, where it's used to make the toothbrush through a 3D printer.

The first Blizzident brush costs $299 and annual replacement brushes sell for $159. The company also offers to refurbish a brush by replacing the bristles for $89.
