Japanese scientists successfully test drug that could stimulate the growth of new teeth
Japanese researchers have made a major breakthrough that could transform modern dentistry. Scientists have successfully completed the first phase of clinical trials of a unique drug that may one day enable people to naturally regrow lost teeth.
Initial tests involving volunteers confirmed that the innovative treatment is safe, with no serious side effects reported during the study.
The drug, currently known as TRG-035, was developed by researchers at the Kitano Medical Research Institute in Osaka in collaboration with scientists from Kyoto University. It works by blocking a specific protein that normally suppresses the development of dormant tooth buds in the human body.
By temporarily disabling this biological barrier, the treatment activates the body's natural mechanism for forming new tooth tissue. The technology had previously demonstrated promising results in preclinical studies on laboratory animals.
The first human clinical trial was conducted at Kyoto University Hospital and involved 30 men, each missing at least one permanent molar.
The research team is now preparing for the next phase of clinical trials, which will involve children aged 2 to 7 with congenital anodontia, a rare condition characterized by the absence of teeth from birth.
If all remaining clinical trial phases are completed successfully, the drug could reach the global market by 2030. For millions of people worldwide, it may become a long-awaited, painless alternative to dental implants and prosthetic treatments.
