No more fillings! Scientists have figured out how to regenerate dentin, the material inside our teeth.
The new study published in Science Translational Medicine shows that a low-power laser can trigger stem cells in your tooth to form dentin.
As Sarah Zhang reports for Gizmodo, currently dentists can only replace damaged dentin with synthetic material, for example, when you get a filling or root canal.
But using this new technique, dentists may soon be able to actually regrow your tooth.
