Shark teeth have built-in toothpaste...
An in-depth look at shark teeth has found that they contain fluoride, the active ingredient of most toothpaste and dental care mouthwashes.
It helps to explain why sharks are so effective at either tearing or cutting prey. Their teeth are perfectly designed for such tasks, never suffering from cavities, according to the study, recently published in the Journal of Structural Biology.

About Me
Sharks have inhabited our planet for 450 million years, since before the time of dinosaurs. If, in some small way, we are able to help people understand the vital role sharks play in ecosystems and the impact this has on all species, including humans, and also to dispel the myth that sharks are ruthless man-eaters, then we will have done a good thing.

Sharks are as tough as those football fans who take their shirts off during games in Chicago in January, only more intelligent.
