Japanese researchers have successfully "grown" a new tooth for a very lucky rodent. Stem cells were used to create a "tooth germ" that harvested in the socket of the missing tooth. After 11 weeks, a fully functioning tooth erupted into the mouth of the mouse, eerily similar to the natural tooth eruption process. According to the study, the resulting tooth displayed essential characteristics of a normal tooth, such as hardness, shape, responsiveness to temperature and stimuli, and the ability to allow for chewing.
Are dentures and dental implants a thing of the past? The researchers have yet to test this procedure on humans, but the mere fact that the possibility of regenerating new teeth is simply fascinating. Even more noteworthy is the fact that this is the first time scientists have created a "fully functioning three-dimensional organ replacement." A significant starting point, the possibility of regenerating functioning organs, based on the model of this tiny regenerated tooth, is astounding!
