No more fillings! Scientists have figured out how to regenerate dentin, the material inside our teeth. All it takes is a quick blast with a low-powered laser, which induces reactive oxygen species, which are chemically active molecules that then activate a growth factor to stimulate dentin growth. The new study is published in Science Translational Medicine and led by a team of Harvard University scientists, shows that a low-power laser can trigger stem cells in your tooth to form dentin. Sure, having a laser pointed into your mouth isn’t that appealing, but it beats a root canal any day.
