Dinti recrescuti

a team from Tokyo's Research Institute for Science and Technology has designed a method for regrowing lost teeth

To make these glowing regrown teeth happen, first the team created a "germ," or a seed from which the tooth can grow. This germ was coded with the fluorescent glowing dye to track the tooth development. Then they transplanted the tooth germ into the jawbone of a rat. Finally, they tested the regrown tooth. The team found that the teeth were essentially as strong as natural teeth and were able to grow nerves throughout, making them very similar to naturally developed teeth.
