In Japan, a tooth regrowth drug will be tested on volunteers

Kyoto University Hospital is preparing for the first-ever human clinical trial of a tooth regrowth drug. The trial will run from September this year until August 2025. The trial subjects are 30 men aged 30 to 64 who are missing at least one molar tooth.

After the first phase of the trial, which will last 11 months, researchers will conduct tests on patients between the ages of 2 and 7 who are missing at least four teeth due to a birth defect (found in 1% of people).

The next step will be tests on patients who are missing one to five teeth due to environmental factors. Only after a thorough analysis of the results of all phases of the trials will a decision be made on whether to allow the drug to enter the market.
