The world’s first human trial of a drug that can regenerate teeth will begin in a few months, less than a year on from news of its success in animals. This paves the way for the medicine to be commercially available as early as 2030.
The trial, which will take place at Kyoto University Hospital from September to August 2025, will treat 30 males aged 30-64 who are missing at least one molar. The intravenous treatment will be tested for its efficacy on human dentition, after it successfully grew new teeth in ferret and mouse models with no significant side effects.
“We want to do something to help those who are suffering from tooth loss or absence,” said lead researcher Katsu Takahashi, head of dentistry and oral surgery at Kitano Hospital. “While there has been no treatment to date providing a permanent cure, we feel that people’s expectations for tooth growth are high.”
Following this 11-month first stage, the researchers will then trial the drug on patients aged 2-7 who are missing at least four teeth due to congenital tooth deficiency, which is estimated to affect 1% of people. The team is recruiting for this Phase IIa trial now.
I had a new tooth start sprouting on the inside of my mouth a while back. The new nerve in it was horribly sensitive, and I thought I had a cracked or damaged tooth before the dentist told me what was going on. I would rather have a nerve-less implant than a new-growing tooth like that again, given the choice.
Edit: It was a random new growth along the outside of my gums in my 20s.
If they can regrow nerves, I think there are some implications that are slightly more exciting than teething…
