People may soon be able to regrow lost teeth! | The future
of dentistry. For centuries, losing an adult tooth meant relying on dentures, implants, or bridges. But now, scientists are on the verge of realizing something once considered impossible: the human ability to naturally regrow lost teeth.
Groundbreaking research in Japan is paving the way, and experts predict that a drug that stimulates tooth growth could be available by 2030.
The science behind tooth regeneration:
researchers at Kyoto University Hospital have developed a drug that targets a protein called USAG-1, which inhibits tooth growth. By blocking this protein, the dormant buds from which teeth develop can be reactivated, effectively allowing the body to grow new teeth.
Animal studies with mice and ferrets have shown promising results, in which the test animals were able to successfully regenerate lost teeth. Encouraged by these results, researchers began the first clinical trials on humans in September 2024.
The first study involves 30 men aged between 30 and 64, each missing at least one molar. To date, the drug has shown no serious side effects in animal trials and, if successful, could also be used in children with congenital tooth loss.
