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.

    I’m used to lasers being used to kill stormtroopers and such, but if it can also grow me new teeth than that’s just the icing on top!

    This is incredible but when will dentists outside of Harvard be made aware of this?

    Lasers were originally for destroying or cutting things. Now they are going to be used to create and grow things. Wow…
