Scientists are regrowing teeth

By the end of this decade, people may have the first drug to grow new teeth.

Japanese scientists have successfully tested a drug on animals that helps regrow lost teeth. This is reported by ZME Science.

Now the lead author of the study and head of the Department of Dentistry and Oral and Maxillofacial Surgery at Kitano Medical Research Institute Hospital, Katsu Takahashi believes that people can grow this third-generation dentition.

“The idea of ​​growing new teeth is every dentist’s dream. I started working on this idea when I was still a graduate,” he said.

Takahashi studied the genes of mice. So, it turns out that the removal of certain genes in rodents leads to the fact that they grow fewer teeth than they should. So, scientists figured out how to change the genes of these animals.

The researchers concluded that mice lacking a particular gene grew more teeth. This is due to the USAG-1 protein. He prevents the growth of more teeth. Therefore, blocking this protein allows more teeth to grow.

“It’s hard to believe that just one gene has such a profound effect on dentition. But once we neutralized USAG-1, we were able to grow new teeth in mice that weren’t born with a complete set. In other words, the first in the world as a dental restorative. Of course, the drug that works so well in mice must now be tested in humans. We hope to pave the way for clinical use of the drugs,” said the researcher.

It is planned that by 2029 the team will be able to conduct large-scale clinical trials. And by the end of this decade, people may have the first drug to grow new teeth.

It will be remembered that earlier the American had a tooth that grew in his nose that was removed.
