Humans may regrow lost teeth soon.
🦷 Humans may soon regrow lost teeth!
A team of doctors in Japan has developed a groundbreaking drug that could allow people to naturally grow a brand-new tooth.
Instead of relying on dentures or implants, this treatment activates the body’s own ability to produce another set of teeth. The research is led by Dr. Katsu Takahashi at Kitano Hospital’s Medical Research Institute. His team discovered that by blocking a protein called USAG-1—which normally prevents extra teeth from forming—they could trigger tooth growth. In experiments with mice, the treatment worked successfully. Now, human clinical trials are being prepared, with hopes of making the therapy available by 2030.
Scientists believe humans may still have hidden “third set” tooth buds, just waiting to be switched on. This idea is inspired by animals like sharks and elephants, which naturally replace their teeth throughout life. Combined with advances in dental tissue and bone regeneration, researchers are confident that reversing tooth loss biologically is within reach.
If all goes well, the next decade could make tooth regrowth a real option for millions of people who lose teeth due to age, injury, or disease.

Europe must show leadership against Trump’s ‘ruthlessness,’ Germany's foreign minister says
With U.S. support in doubt, German foreign minister warns that Europe must lead on Ukraine or risk losing its security.
BERLIN — As European leaders prepare to meet in London on Sunday for an emergency summit on Ukraine, German Foreign Minister Annalena Baerbock has called for Europe to show decisive leadership in the wake of the Oval Office clash between U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy.
In a starkly worded speech delivered Saturday in the Foreign Ministry, Baerbock warned of a “new era of ruthlessness” following Trump’s public humiliation of Zelenskyy and the U.S. administration’s shifting stance on Russia's invasion of Ukraine.
“A ruthless time has begun, in which we must defend the rules-based international order and the strength of law more than ever against the power of the strongest,” Baerbock said.
