Some sharks get a new set of teeth every few weeks, while crocodiles can go through thousands of chompers in their long lifetimes. Yet the ability to endlessly replace our pearly whites is something that’s eluded us and nearly all other mammals. By the time our 32 ‘adult’ teeth grow in, that’s as good as it gets.
Now, a Japanese team of scientists is set to trial an experimental drug that would allow humans to grow completely new teeth.
A clinical trial scheduled for July 2024 will initially be for participants with tooth agenesis, a genetic condition that results in the absence of teeth, but the scientists have a view to making the treatment available for general use by as soon as 2030.
