Can you imagine reaching 70 years old with strong teeth like those of a 20-year-old? Without dentures, without implants, and with a natural smile? What once seemed like science fiction... is now closer than ever.

In Japan, scientists at Kyoto University Hospital are already testing a drug on humans that could reactivate the body's natural ability to generate new teeth.

They first achieved this in mice and ferrets: the drug blocked a protein that normally stops dental growth after childhood... and the teeth grew back on their own.

Now, human trials aim to verify if the same can happen in people who have lost dental pieces.

If the tests are successful, this advance could change the lives of millions of people around the world.

No more dentures. No more screws. Just real teeth, once again.
