Sharks can kill you…with their minty freshness?!?!?!
Scientists from University of Duisburg-Essen have found that a shark’s teeth is made of FLUORIDE!
For comparison, a human’s tooth is 1 percent. A shark’s tooth?
100% FLUORIDE!
So, not only are their teeth stronger than a human’s, they never get cavities (in theory).
Also, while humans have 32…some sharks shed over 35,000 in a lifetime!
That’s a punch in the mouth!
