By Australian silversmith Polly van der Glas, this teeth jewelry, well...it's kind of like ivory with a touch of plaque—I mean—patina. And the "stones" make a fashionable defensive alternative to brass knuckles.

Look, we know this stuff is horrendous. But really, it's only just as offensive as Kay's latest heart crossed with lips cross with angels pendant. So there. [Van Der Glas via ecoutree via inhabitat]

Basically that little mouse, let's call him Jerry, lost a tooth and grew a a new one in its place with the help of some scientists:

To create the new tooth, the researchers [...] took epithelial cells and mesenchymal cells (about 50,000 each) from a mouse embryo and cultivated them together in a collagen-based medium to create a tiny tooth bud - a mass of tissue that has the potential to develop into a tooth.

This mass of tissues was implanted in the spot where Jerry's old tooth used to be and after fifty days that mouse could nibble on cheese properly again. The new tooth grew to the same height as the surrounding ones, is just as hard, and has all the same blood vessels and nerves.

Researchers are hoping that this bioengineering process will one day make dentures and false teeth obsolete, but I think that anyone watching Shark Week is secretly imagining growing a mouthful of chompers like that. [PinkTentacle]

Although shooting a stream of plasma into your mouth sounds painful, the blowtorch actually works in small pulses, which lets the flame's gasses ionize and cool down a little before they can burn you. So far, dentists have only used this technology to sterilize teeth during root canals, but have a few other ideas on where else to use it—perhaps, in the future, zapping away diseases on your genitals? [R and D via PopSci]

How does it work? It's essentially a mouth guard—you know, like the ones boxers use—that you use while performing oral sex. On a male.

It retails for $28 and contains a pack of strawberry flavored lubrication. Not sure whether or not the lube goes on the inside as well as the outside of the Blowguard, but you can use it how you like. It's a seriously good idea, as any guy who's been accidentally teethed can attest to. Not sure how it feels on the giver. Probably not that much worse than having a penis in the mouth.

Fleshbot (NSFW) will have a review of it soon. [Blowguard (NSFW)]

The professor and his student have shown that "bad" bacteria cannot stick to the surface, which is great, since it's the type of bacteria that cause dental bills. Teeth polished with nanoparticles still may have bacteria on it, but from what I'm reading, can be easily removed. Easier than with brushing, or else this thing isn't really an advance at all.

It's too bad that by the time the technique is productized and deployed to actual dentists, I'll be 50 and have been toothless for 20 years. [Science Daily]

Here’s your opportunity to have Hollywood white, super-healthy teeth, thanks this revolutionary, super-safe, medical-quality laser toothbrush. It has an energy concentration so low that any tissue surface, even eye tissue, is safe! It works with a programmed tooth management system that turns on the laser for a recommended treatment period (55 seconds) with one-touch mode switch. In this case, the laser toothbrush does not need toothpaste but directly radiates laser on teeth. This revolutionary semiconductor medical laser helps decrease sensitivity, toothache pain, inflammation, and even helps eliminate bad breath. No more messy toothpaste accidents, now you can clean your teeth with light! [AA batteries included]

Don't trouble yourself with working out exactly how the laser is powerful enough to burn plaque and germs but leave your gums, teeth and eyes intact, because we can tell you how. It's a freaking laser.

Maybe we're being to hard on the Smart Miracles Laser Toothbrush. Maybe this $69.95 device operates just as advertised, eliminating bad breath and decreasing sensitivity while not necessarily doing a damn thing for actual tooth health—after all, a tongue cleaner can eradicate most morning mouth without cool beams of light. But still, I'm not trusting it to do anything right related to my precious oral hygiene. And I love lasers. [Smart Miracles via bookofjoe]

This method would make it possible to detect damage much faster than X-rays, nipping the problem in the bud before drilling is necessary. The testing is ongoing, but the researchers hope that the lasers could be available commercially within the next five years. Of course, you would have to actually go to the dentist on a regular basis to benefit from the procedure, so my guess is that drilling won't disappear anytime soon. [eurekalert via ZDNet]

This gadgetry doesn't come cheap though, costing as much as a trip to the dentist at $280. It will be available in the UK from next month.[Spuch]

As of right now, the device can only turn a CD player on and off (I mean, give a guy a DVD player at least). But scientists are confident that the controls have far more potential, with the goal of checking email on a mobile device. It reminds me of Back to the Future II. "You get to use your hands? That's like a baby's toy!"

Suddenly it raised its little helmet and beamed a red laser on us. Confused by what was happening we focused on the bright light, only to be relentlessly pelted by plastic glow-in-the-dark discs. And they weren't just gently trickling out either, the Tri-clops launches them out reaching distances as far as 20-feet. And the fun doesn't run out after 5-10 minutes like R/C cars used to when I was a kid, Tri-clops will go run at full speed for over a half hour. All of this crazy laser-guided R/C destruction will cost you $99.99, look for it this month.

Dento-Munch's upper and lower "jaws" consist of two platforms. The lower one is capable of moving six degrees of freedom (unlike the current lab simulators, which are only capable of 2 degrees) and can move and rotate up and down, forwards and backwards, and left and right - just like its human counterpart.

The software that controls the robot's motors and gearboxes responds to loads as muscle and tendon does, and the chewing is slowed when resistance is high (and speeded up when it is low) thanks to feedback loops in the system.

Mr Alemzadeh also thinks that the machine will work for research on ankles, as the movement in the joint that links the foot to the leg is similar to chewing.

The watch comes in either silver or gold, but costs only $140 (16,800 yen). The point? To remind you every day that it's time to go to the dentist. Or eat more candy. – Jason Chen

The ID tags would be used to store personal information about individuals and would enable forensic teams to identify bodies in catastrophic events.

The ID tag being used is an adapted RFID tag, similar to the ones used in animals for tracking purposes. The tag is able to withstand the repetetive biting force, along with resistance to extreme heat and cold, but there are still concerns with the tag being able to withstand the expansion and contraction of tooth due to sporadic heating and cooling. Creepy, no?
