Rarely, someone has a condition called hyperdontia where they have more than 32. This happens with around 1-2% of the population. Sometimes, those with hyperdontia barely even notice the difference.

Pigs are the unlikely model for this latest research into regenerating human teeth. Image source: agnormark/Adobe. In a recent study, Yelick and her team successfully grew human-like teeth in pigs.

The pig’s mouth revealed its ordinary sharp, tusk-like canines saddled up beside smaller, slightly more human-looking teeth nubs. In theory, a similar process could play out in humans.

Tufts University researchers took material from human and pig teeth and were able to grow a tooth-like structure. They hope their findings could lead to growing living tooth replacements for people.

The team says that humans have a third set of teeth available as buds, ready to grow as needed. A sliver of what makes sharks so intriguing comes with their ability to regrow teeth.

A recently-published study revealed that scientists grew human-like teeth in a pig's mouth by using a mix of human and pig DNA. Tue, 27 May 2025 00:15:46 GMT (1748304946579) Story Infinite Scroll ...

By studying proteins preserved in teeth, researchers determined the sex of four Paranthropus robustus individuals that lived ...
