From lab-grown internal organs and stem cell research to test-tube babies and cloning, modern science is working overtime to create or recreate working, sustainable biological matter. Next on the list: teeth. So if you’re outside the Tooth Fairy’s target market or simply have a few gaps in your grin, you could be in luck.

Nanotechnology expert Dr. Jie Chen and his associate Dr. Ying Tsui from the Faculty of Engineering at the University of Alberta have developed a new ultrasound transducer to stimulate the growth of teeth and fix asymmetric jaw bones. The transducer utilizes LIPUS, which stands for “low-intensity pulsed ultrasound.” The miniature, wireless device does exactly what its name suggests: it sends pulses of ultrasound into biological matter, such as gums, muscles or bones to increase healing or stimulate growth of new tissue.
