It's now possible for scientists to regrow actual teeth thanks to the efforts of a team of scientists. A Harvard-led team of researchers found that using a laser beam could trigger human dental stem cells, causing them to create dentin - the kind of tissue that's found underneath the enamel and makes up the majority of the average tooth.
It's historically been difficult to coax stem cells into this kind of specialized growth, according to Digital Trends. But this new technique has done the trick in a lab environment and with animal models. This laser method, outlined in the Science Translational Medicine journal, could even be used for different organic materials if development continues.
It's probably not time to throw out the Colgate just yet, but for now this is a promising step forward in the area of regenerative stem cell research.
