World's 1st 'tooth regrowth' medicine moves toward clinical trials in Japan - The Mainichi

TOKYO -- A Japanese research team is making progress on the development of a groundbreaking medication that may allow people to grow new teeth, with clinical trials set to begin in July 2024.

The tooth regrowth medicine is intended for people who lack a full set of adult teeth due to congenital factors. The team is aiming to have it ready for general use in 2030.

Work is now underway to get the drug ready for human use. Once confirmed to have no ill effects on the human body, it will be aimed at treating children aged 2 to 6 who exhibit anodontia. "We hope to pave the way for the medicine's clinical use," Takahashi said.

Although this will be used for congenital defects in children in Japan, I see no reason this couldn't be used in adults as well. Regrowing all your teeth at once might be painful, but it will be worth it for many.
