Dental medicine improves constantly and according to the latest advancement it may be possible to regrow pearly white teeth. Dr Jeremy Mao, the Edward V. Zegarellu Professor of Dental Medicine at Columbia University Medical Center, explains that a three-dimensional scaffold with growth factor has the potential to regenerate and regrow anatomically correct teeth within just nine weeks after the implantation. The procedure was developed in the Tissue Engineering and Regenerative Medicine Laboratory at the university. In the process, the body's own stem cells go toward the scaffold, which consists of completely natural materials. Once the scaffold is colonized with stem cells, the tooth starts growing in the socket, and later merges with the surrounding tissue. In this way teeth do not grow in a Petri dish, and anatomically correct teeth regenerate by using the body's own material. This dental treatment offers a faster recovery time and, unlike implantation, a completely natural regrowth
