Harvard-led team of scientists has just published their findings demonstrating a way to regrow teeth using lasers. Say goodbye to fillings and prosthetics, this new technology could theoretically be used as a foundation for other regenerative procedures. 
Published yesterday in the journal Science Translational Medicine, the procedure used to achieve this tooth regrowth sounds like it’s taken straight out of a science fiction novel. The team used a low-power laser beam to trigger human dental stem cells and encourage them to form dentin: the hard, bone-like tissue that lies underneath a tooth’s enamel and makes up the bulk of a tooth’s mass.
