This 3D-Printed Device Promises To Clean All Your Teeth At Once

Custom-made from a dental scan and designed to fit over the teeth, the Blizzident claims to do the job of a regular toothbrush in only six seconds.

What's the Latest Development?


The newest household device to get an extreme design remake courtesy of 21st-century technology is the toothbrush. For a mere $300, the makers of Blizzident will take a dental scan of your teeth (which you'll have to get from a dentist at additional cost) and use special 3D printers to turn it into an inverse plastic mold that they then line with hundreds of soft bristles. To use it, all you have to do is apply toothpaste to your tongue, move it over your upper teeth, insert the mold into your mouth, and chew on it for approximately six seconds. That's all it takes, they claim, to give you "perfectly clean teeth." One Blizzident lasts a year; replacement costs will set you back $90 (bristles only) or $160 for a new mold.

What's the Big Idea?

Considering that for most of history tooth cleaning has required -- ideally -- close attention, there's something to be said for a device that attempts to take care of all your choppers at once. Writer Sebastian Anthony notes that, assuming some flossing is included, the six-second claim offered by Blizzident adds up to a time savings of "just under 55 hours" per year. Not surprisingly, various dentists and others have expressed skepticism over whether this newfangled toothbrush can live up to its hype.

  • Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
  • These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
  • The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.
