Scientists from the University of Sheffield (UK) have come to the conclusion that a person can regenerate teeth in just one day.
Today sharks have the ability to restore teeth. By studying the process of tooth regeneration in sharks, scientists have discovered genes that are responsible for the regeneration of teeth in these marine predators. As the head of the research group Garrett Fraser notes, there are 400 genes that are responsible for the growth of teeth.
Similar genes are also present in humans, Fraser said, but their numbers are significantly reduced compared to the genes responsible for tooth regeneration in sharks. Researchers explain the presence of similar genes in humans and sharks by the existence of a common ancestor.
In addition to sharks, scientists note, new teeth can grow throughout life in bony fish, as well as in reptiles. At the same time, most mammals lack this ability.
Researchers have established how genes responsible for dentition repair "work" in sharks. According to scientists, in humans, these genes die off or go dormant after milk teeth fall out and all permanent teeth grow.
If scientists succeed in developing a technique that will "turn on" the necessary genes, there will be no need for denture prosthetics, since the body will be able to restore the lost tooth on its own.
