Drug that can regrow missing human teeth finally enters clinical trials

Earlier this year, scientists revealed that a new tooth-regrowing drug would enter human trials before the end of 2024. They’ve cut it close, but Japanese dentists testing the new tooth-growing drug finally launched the next phase of their clinical trials in October at Kyoto University Hospital.

The drug builds off a little-known secret hiding just beneath the surface of our gums. See, it’s pretty well accepted that humans and most other mammals only have two sets of teeth that they can grow.
