"Researchers in Japan are testing a groundbreaking drug that could potentially regrow human teeth, offering a natural alternative to dentures and implants. The drug works by targeting a protein called USAG-1, which typically inhibits the formation of new teeth in adults. By blocking this protein, the drug stimulates dormant tooth buds in the jaw to start growing new teeth. Early studies in animals, including mice and ferrets, have shown promising results, with the regrowth of teeth in areas where they were previously missing. The first human trials began in late 2024, with volunteers who are missing teeth.
If successful, this drug could provide a revolutionary solution to tooth loss, allowing people to regrow their own teeth rather than relying on artificial replacements. However, the research is still in its early stages, and it may take several more years before the drug becomes commercially available. If proven effective, it could change the landscape of dental care by offering a more natural, less invasive solution for tooth regeneration.
