In other words, the treatment could — potentially — be used to regrow human teeth. Think of it as a futuristic alternative to invasive implants or dentures, leveraging the body's own abilities instead. The company is now planning to kick off human clinical trials in July 2024 and, depending on the results, eventually bring the drug to market by 2030, the [*Japan Times* reports](). "\[Our\] final goal is to offer advanced and scientifically driven clinical solution for the growth of teeth derived from their own tissues," Toregem's president Honoka Kiso wrote on the [company's website](). The drug works by inhibiting a gene called USAG-1, which is responsible for stopping "tooth buds," which most people have, from ever developing into either baby or permanent teeth. By inhibiting that gene, the idea is Toregem's new drug will stimulate the growth of these buds. Some animal research has been promising. In 2018, the team tested the drug on ferrets, which have similar tooth buds to humans, and found that new teeth grew successfully. In 2025, the company is hoping to kick off trials with children between the ages of 2 and 6 who have anodontia, a genetic disorder that stops them from developing permanent teeth. Beyond these kinds of genetic disorders, Toregem Biopharma is also hoping to help adults who have lost teeth due to cavities as well. "The idea of growing new teeth is every dentist's dream," co-founder and lead researcher Katsu Takahashi, head of the dentistry and oral surgery department at the Medical Research Institute Kitano Hospital in Osaka, [told Japanese newspaper *The Mainichi*]() earlier this year. "I've been working on this since I was a graduate student." "We're hoping to see a time when tooth-regrowth medicine is a third choice alongside dentures and implants," he added. **More on teeth:** *[Research Suggests That Bad Dental Health May Increase Risk of Dementia]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
