When it comes to things that people don't do as often or as well as they should, tooth-brushing would have to be at the top of the list. While it usually just comes down to laziness, a lot of people claim that they don't brush their teeth properly because they don't have time. Well, with the new Blizzident toothbrush (if it can be called a toothbrush), a full and complete cleaning of the teeth can reportedly be accomplished in just six seconds.
Before they can receive a Blizzident, users first have to go to their dentist and get an impression made of their teeth. Next, a 3D digital model of that impression is uploaded to the Blizzident company's server. The company proceeds to create a 3D-printed plastic negative mold of the teeth, which is lined with approximately 400 toothbrush-style angled bristles. That mold is the actual Blizzident toothbrush, and is sent to the buyer.

To brush their teeth, users just put the Blizzident into their mouth, bite up and down into it, and grind their teeth back and forth. Because it's an exact fit for their teeth, six seconds of chomping and grinding is reportedly long enough for the bristles to get into all the nooks and crannies, including between teeth and along the gum line.
If they wish to, users can also thread dental floss between the individual tooth impressions on the Blizzident, causing that floss to be pushed up between the teeth when they bite down. A role of floss can be held in a dispenser on the front of the brush.
Finally, a tongue scraper/brush bridges the top of the toothbrush. Users just run their tongue back and forth against it.
One Blizzident is said to be good for a year of use, after which users can get a completely new one, or send their old one in for cleaning and re-bristling. A buyer's first brush will cost them US$299, with subsequent replacement units priced at $159, and refurbishments of existing units costing $89. The company also notes that getting the initial impression made by a local dentist should cost between $75 and $200, depending on the technique used.
