Scientists Have Discovered The Regrow Tooth Gene

Scientists have discovered that we all have a gene in our bodies that will stop the regrow tooth process. This is why when out teeth grow in, there is no more tooth growth after that. They have found out that there are several species that do not have this gene such as the shark for example. This is why the shark has so many teeth in their mouth. They are trying to find a way to take control of this gene so that they can start the process of regrowing the teeth after a person has lost theirs and then stop the growth again after the person has their new set of teeth.
