Sharks are famous for regrowing teeth, but Japanese researchers aren’t suggesting we turn into aquatic predators. Instead, they’re working on a groundbreaking dental solution.
Building on a 2021 study that triggered tooth regrowth in animals by targeting the USAG-1 gene, the team is launching a 2024 clinical trial for humans. If successful, they aim to have this tooth-regeneration treatment available by 2030.
Lead researcher Katsu Takahashi sees this as a dentist’s dream come true. By blocking the USAG-1 gene, mice grew new teeth, offering hope for the 1% of humans with anodontia, a condition preventing a full set of teeth.
Takahashi’s research reveals that humans already possess the potential for a third set of teeth, like a dental backup plan. Get ready to smile wider, as tooth regrowth might become as routine as a checkup by 2030!
