Japan have invented a tool that permits you to grow new teeth instead of lost permanent ones, reports the “MIR 24” portal. According to the authors of the invention, such a preparation will help to grow teeth in patients with a missing full set of teeth due to congenital factors.

When developing a preparation for growing teeth, Japanese dentists relied on the ability of sharks and some reptiles to grow new teeth throughout their lives.

Preliminary tests on rats showed positive results - the rodents grew new teeth instead of lost permanent ones. In the near future, the drug may begin to be used to treat people.
