Scientists Invent Teeth-Regrowing Device

Say goodbye to dentures.
Scientists from the University of Alberta in Canada have claimed to have created a device capable of regrowing teeth and bones. According to an AFP report, the inventors have already filed patents for the device, which is based on low-intensity pulsed ultrasound or LIPUS technology.
"Right now, we plan to use it to fix fractured or diseased teeth, as well as asymmetric jawbones, but it may also help hockey players or children who had their tooth knocked out," Jie Chen, an engineering professor and nano-circuit design expert, told AFP.
Chen helped create the tiny ultrasound machine that gently massages gums and stimulates tooth growth from the root once inserted into a person's mouth, mounted on braces or a removable plastic crown.
The wireless device, smaller than a pea, must be activated for 20 minutes each day for four months to stimulate growth, he said.
It can also stimulate jawbone growth to fix a person's crooked smile and may eventually allow people to grow taller by stimulating bone growth, Chen said.
However, it's still a wee bit early for sweet-toothed people to be dancing in the streets over this bit of news. Although the device has already been tested on a dozen dental patients in Canada, it's still at the prototype stage. According to the inventors, it might take another two years before their teeth-regrowing gadget hits the market.
