Dentists may soon be getting a potent new weapons with which to wage the global fight against cavities. The University of Maryland has developed a novel new nanocomposite material that can be used not only as filling for cavities, but that will also kill any remaining bacteria in the tooth and regenerate the actual structure lost to decay.
Attentive followers of dentistry developments that we are, we've been following the story of the plasma brush for awhile now. And it seems like it's making some serious progress: human clinical trials are supposed to begin in early 2012, and there's also a video (below) of the World's Bravest Dentist shooting a plasma beam into his own mouth.
A new tooth-regenerating paste could reverse bacterial-induced tooth decay, sweeping dental drills into the dustbin of history. Hopefully.
As your hygienist probably told you, tooth decay happens when bacteria in plaque dissolve your enamel, creating cavities. Eventually the cavity gets big enough that your dentist has to take out the decay and drill a hole that can be filled with resin, gold or something else. But a new treatment developed at the University of Leeds in the UK reverses the decay, allowing your teeth to rebuild themselves.
Humans have invented all kinds of high-tech fixes to deal with plaque in the heart, but when it comes to battling tooth decay, a manual scrubbing with a bristle-brush is still our primary line of defense. But Dutch researchers may have just bested the toothbrush by characterizing and deciphering the structure of the enzyme responsible for plaque sticking to teeth. By adding an inhibitor to toothpaste or even to the food we eat, tooth decay and cavities could soon become a rarity.
Space technology is about to make your visit to the dentist a little more comfortable. The same production technology that made the world’s tiniest rocket motor will be used to shrink those unwieldy plastic squares the dentist sticks in your mouth during an X-ray.
Scientists must really dread the dentist -- they're always coming up with new solutions to help people avoid that cursed drill. The latest: a hormone gel that regenerates tooth cells in as little as a month.
The gel, the first of its kind, could eliminate the need to fill cavities or drill into the root canal of an infected tooth, Discovery News reports. It is reported in the journal ACS Nano.
Just the sound of a dentist's drill is enough to send most people into a panic. Add to that the awful inconvenience of walking around for a day with half your face numb, and it's easy to see why getting a cavity filled or a tooth replaced is one of life's most annoying chores. Fortunately, some new research may make the common drill-and-fill a thing of the past.

Video games may be good for your dental health. Not for the jaw-clenching or tooth-grinding action -- discuss these conditions with a professional if they persist in conjunction with gaming -- but because dentists will soon have access to virtual mouths before they get their hands on your chompers.
