New Drug to Regrow Teeth Enters Human Trials

Japanese researchers developed a drug to regrow teeth, set to begin human trials in September.

The drug blocks the USAG-1 protein, which suppresses tooth growth.

Initial trials will involve adults missing a molar, followed by children with congenital tooth deficiencies and older adults missing teeth due to environmental factors.

Successful trials in ferrets and mice showed no serious side effects.
The drug could be available by 2030.
