Human teeth could eventually be made to regrow just like those of sharks as we still possess the same genes that allow regrowth, scientists have found.

Sharks and other fish regrow their teeth repeatedly through their lives while humans have the capacity to regrow their teeth just once.

But now scientists at the University of Sheffield have discovered that the same network of genes that allow sharks to regrow teeth is present in humans.

Dr Gareth Fraser and colleagues analysed the teeth of catshark embryos, and identified the genes involved during stages of early shark tooth formation.

These genes continue to be used to grow further teeth and are found in cells called the dental lamina, which are responsible for the lifelong continuation of tooth development and regeneration in sharks.

The same genes are still present in humans – deriving from the time when humans and sharks had a common ancestor.

The famous Dr. Jeremy Mao of Columbia University was the lead investigator of this research and what he found was absolutely incredible. Dr. Jeremy Mao built a scaffold for teeth, containing these stem cells in the body.

He actually helped new teeth regeneration, with just using their DNA. So, this modern technology promises a bright future for dental care.

What if we tell you that you can avoid the painful and long process of extracting the teeth?
This modern technology gives you the opportunity to grow your teeth in just nine weeks. The device has to be placed and accepted by the body. The best thing about this implant method is that it uses good materials to replace the missing tooth or teeth.

Dr. Mao said:

“Your missing tooth is being replaced with stem cells, from your own body. And the tooth merges with the surrounding tissue. Yes, it’s simple as that! This will increase the regeneration process and it will result in fast recovery.”

Note: This procedure is not yet available for all the people in the world. It’s still in researching process and it is pending approval from the medical authorities.
