Japan: Drug May Allow People to Grow New Teeth
June 13th, 2026Via: Popular Mechanics:
Japanese researchers have moved forward with an experimental drug that promises to regrow human teeth. Human trials began in September 2024.
…
This study focuses on 30 males between the ages of 30 and 64—each missing at least one tooth. The drug will be administered intravenously to prove its effectiveness and safety, and luckily, no side effects have been reported in previous animal studies.
If all goes well, Kitano Hospital will administer the treatment to patients between the ages of 2 to 7 who are missing at least four teeth, with the end goal of having a tooth-regrowing medicine available by the year 2030. While these treatments are currently focused on patients with congenital tooth deficiency, Takahashi hopes the treatment will be available for anyone who’s lost a tooth.
