'S.T.A.L.K.E.R. 2' devs are spending a lot of time on teeth
The 'S.T.A.L.K.E.R. 2' developers made a teeth customization tool to play dentist with the horror game's characters.
Get ready to hear about Quip's new floss dispenser on all your podcasts
The podcasts you listen to will never be the same. That's because one of the biggest advertisers in the space, toothbrush subscription startup Quip, finally has a new product. On Tuesday, the company announced a refillable floss dispenser simply called Floss.
Baby tooth stem cells could regrow kids' dental tissue
If you injure a tooth as a kid, there's a real chance you'll grow up with a 'dead' tooth whose roots didn't grow properly due to tissue damage. However, scientists have conducted a successful trial for a method that could regrow kids' dental tissue using stem cells from their baby teeth. The team extracted human deciduous pulp stem cells (hDPSC) from patients' healthy baby teeth, allowed the cells to reproduce in a lab culture, and implanted them in the injured teeth. A year later, enough healthy tissue had regrown that the kids could feel at least some sensations, such as hot or cold.
Battery-free toothbrush is powered with a twist
Battery-powered toothbrushes are convenient if you don't like brushing your teeth the old-fashioned way, but they have a catch: batteries. Typically, you either need to dock your brush (and remember to carry a charger with you on long trips) or toss disposables when they're done. There might be a better way soon, though: Goodwell Co. is crowdfunding Be, which it bills as the first battery-free powered toothbrush. Twist the base twice and a kinetic energy storage mechanism will vibrate the brush head for up to 2 minutes, or just long enough for that dentist-recommended cleaning. You don't have to connect to a charger, and you won't contribute to landfills by chucking out batteries (the bristles are even biodegradable).
Scientists create 'tooth cracker' device to harvest stem cells
That pesky wisdom tooth you're glad you got rid of is apparently a great source of stem cells that could save lives. However, it's not easy getting to the tooth root pulp that contains those cells: drilling into the tooth generates damaging heat that lowers the number of cells that can be harvested. In addition, the water used to rinse the tooth could have corrosive elements and the enamel particulates from the drilling could contaminate the pulp. To solve that issue, a team of researchers from the University of Nevada Las Vegas have developed a device they hilarious call the "Tooth Cracker 5000" to extract 80 percent of the stem cells a pulp contains.
Oral-B's latest smart toothbrush has one fatal flaw
Oral-B, those purveyors of tools to keep your teeth clean, have been making Bluetooth electric toothbrushes for a few years now. But its latest, the Oral-B Genius 8000, is the Cadillac of connected Bluetooth toothbrushes, if you're in to that sort of thing. What's interesting about the Genius is that it uses your smartphone's front-facing camera to analyze your brushing patterns and ensure that you're hitting every zone of your mouth sufficiently before you move on. The company has seen that when people brush, they often accidentally skip over or under-brush parts of their mouth, and this is meant to fix that.
Disney can digitally recreate your teeth
Digital models of humans can be uncannily accurate these days, but there's at least one area where they fall short: teeth. Unless you're willing to scan the inside of someone's mouth, you aren't going to get a very faithful representation of someone's pearly whites. Disney Research and ETH Zurich, however, have a far easier solution. They've just developed a technique to digitally recreate teeth beyond the gum line using little more than source data and everyday imagery. The team used 86 3D scans to create a model for an "average" set of teeth, and wrote an algorithm that adapts that model based on what it sees in the contours of teeth in photos and videos.
Regenerative tooth fillings could put an end to root canals
You really don't want a root canal, and not just because it's potentially painful. Emptying the tooth of the infected tissue at its heart potentially weakens it, since you can't grow that organic material back or put toxic fillings in its place. Researchers may have a solution, though. They've crafted fillings that get the tooth's own stem cells to regenerate and repair tissue. This doesn't mean that your pearly whites would return to normal, but the substance could heal the tooth enough to spare you a root canal or prevent fillings from going south.

The Prophix is a video toothbrush tool that can live stream your choppers and save pictures of them to an app in case you're obsessed with the way your teeth look.
Scrubbing with a toothbrush that knows when you missed a spot
Mobile World Congress is predominantly about smartphones, however look hard enough and you'll find all sorts of other surprises too. Take Oral-B, which chose Barcelona as the place to announce the B-Genius, a new toothbrush that knows exactly where you're scrubbing. A built-in accelerometer clocks the angle, while your phone's front-facing camera tracks its location and your dentures. As you brush, the companion app highlights the places you've cleaned and the spots you might have missed. So of course, we had to try it for ourselves and see if it's worth the hassle.
Sea snail teeth may be the key to super-light race cars
It's increasingly common to find supercars, laptops and other gadgets clad in strong-yet-light carbon fiber, but scientists may have a better (if decidedly stranger) solution: sea snail teeth. The University of Portsmouth has determined that a fibrous mineral structure found in limpet teeth is so strong that it could be used for the shells of race cars and many other devices where a strength-to-weight ratio is important. It's even stronger than spider silk, the previous natural strength champion, and the tooth's structure doesn't become more fragile as it gets larger.
Electric toothbrush mates simplicity with low-cost subscriptions
You could easily argue that many attempts at modernizing the toothbrush are overkill -- motion tracking and smartphone tie-ins are a bit much for cleaning that should only take a couple of minutes if you're doing it right. Quip (no, not that Quip) thinks there's a better solution. Its newly unveiled combination of a toothbrush and subscription service is just smart enough to keep your teeth in pristine shape. The electric brush's only proper trick is a vibrating handle that stops when it's time to scrub another section of your mouth. The real cleverness comes through the low-cost subscription model: you pay $25 to $40 for a starter kit ($5 to $20 for a non-electric brush) and $10 every three months for both new bristles and two tubes of toothpaste. It's decidedly cheaper than Goodwell's recently unveiled subscription model ($69 before the plan kicks in), and you can buy things piecemeal if you're not down with regular payments.
Put your back out again? Doctors now available to order through Zesty
Zesty.co.uk launched this time last year as an online portal for booking last-minute dentist appointments at clinics across London. While it's no doubt been useful for anyone that needs an emergency (and likely extortionately priced) filling, the site has now expanded to help you access other healthcare services at short notice. Whether you're in need of a chiropractor, osteopath, physiotherapist or sexual health professional, you can use Zesty to check for open appointments in your local area. You can even book in to see a GP, but only at private clinics -- for a short-notice slot at your own NHS surgery, we're afraid you'll still have to be on the phone by 7am. In its quest to "make healthcare appointments as easy as ordering a pizza," Zesty plans to go almost UK-wide later this year and release a native app to compliment its mobile-optimised site. Before you get the wrong impression from Zesty's strange tagline and accompanying imagery: your pizza delivery guy is not qualified to give medical advice.
3D printing shows why sharks are so deadly efficient
A shark's fearsome teeth don't end in its mouth, as its skin is also made up of millions of sharp, microscopic "denticles." That roughness helps sharks slip through the water more efficiently by reducing drag, but how exactly? To better understand, Harvard researchers studied a Mako shark's skin, then figured out how to 3D print a simulated version onto a flexible substrate (see below). As expected, the faux sharkskin reduced drag significantly at slower speeds, but surprisingly increased drag in faster currents. After adding a simulated swimming motion, however, efficiency improved dramatically -- showing that denticles only work in concert with a shark's sinuous movement. All that helps them swim seven percent faster and burn six percent less energy than if their skin was smooth. That might not seem like a lot, but let's see you hunt down and kill a seal with your bare teeth. (A decoy seal is pictured above.) [Image credit: Discovery Channel]
Oral-B's app-connected toothbrush now rescuing British teeth for £230
Oral-B's electric toothbrushes spin, vibrate and get into places your standard scrubber can only imagine, but none are more extravagant than the new "Smart Series" launched today. The Bluetooth-endowed brushes -- yes, they're a thing now -- pair with iOS devices (an Android app's due in August) and tell you how terrible your oral hygiene is, with the hope of improving it. Basically, the app allows you to choose different brushing routines, with your iPhone showing a timer (as well as news and weather reports to distract you from the dull task at hand), telling you when to move on to different areas of your chops, and notifying you when you're putting too much pressure on your teeth. Oral-B's actually had toothbrushes with similar functionality for many years, but they've all required additional hardware that's replaced by your phone in this new Smart Series. Kind of like a fitness tracker for brushing, the app will also store session data so you can build up a record of successful scrubs.

Hanako 2 robot acts like a human dental patient, makes us say 'aah' (video)
No, she's not in a state of shock, nor is she hunting for plankton -- she's simply waiting for the dentist to polish her pearly whites, just like any other conscientious robot. Known as the Showa Hanako 2, this humanoid was originally developed last year as a tool for dentists looking to practice new procedures. Now, engineers at Japan's Showa University have updated their dental denizen, adding a motorized head and replacing her PVC skin with a more realistic silicon coating. She also boasts speech recognition capabilities and can execute freakishly natural movements, including blinking, sneezing, coughing and, under more unsavory circumstances, even choking. See her in action for yourself, after the break.
Stronger-than-steel palladium glass paves way for dental implants of the future
A team of researchers at Caltech and the Lawrence Berkeley National Laboratory have created a new type of glass that's stronger than steel, but it might not make it out of your oral surgeon's office. The material is a combination of glass' simplest form, called marginal glass, the metal palladium, and small fractions of phosphorus, silicon, germanium, and silver, making it resistant to massive amounts of pressure and strain. A glass this strong has endless potential in the way of structural application -- think cars, planes, and bridges. Thing is, though, palladium is super expensive, and researchers involved in the project say the best applications are in products like dental implants, which are currently made of soft, stiff noble metals, more likely to cause complications like bone atrophy. Chances are we won't see super strong glass bridges anytime soon, but the new glass dental implants could be in your mouth as early as 2016.
Researchers hope tooth regeneration gel will reduce the need for fillings
We may still not have jetpacks or flying cars, but it looks like the 21st century might be about to get a bit more futuristic. As Discovery News reports, a study published in the ACS Nano journal is offering some fairly convincing evidence that a new type of hormone gel could potentially regenerate teeth and eliminate the need for fillings in at least some cases. According to the French scientists behind it, the gel has already managed to make cavities in mice "disappear" after only a month, and the peptide used in the gel, MSH, has also previously been shown to encourage bone regeneration. Of course, it will be a little while yet before your dentist puts down the drill -- the researchers say there still needs to be "several years" of clinical trials, and note that it likely won't replace fillings altogether (or prevent them).
