Why can’t we tap into the sharks DNA to replace our missing teeth? Sharks have a unique dental structure that allows for the continuous replacement of their teeth, which is facilitated by their DNA. Unlike humans, sharks have multiple rows of teeth in their jaws, with new teeth constantly developing to replace those that are lost or damaged. This regenerative ability is encoded in the genetic makeup of sharks, enabling them to maintain a functional set of teeth throughout their lives. In contrast, humans only have two sets of teeth – primary and permanent – and once the permanent teeth are lost, they are not naturally replaced. Therefore, the regenerative capacity of shark teeth is a distinct genetic trait that differs from the dental characteristics of people.
