After you wake up, brushing your teeth might be at the top of your list of things to do. Well, here are a few facts about shark teeth to go with your toothpaste! While you're brushing in the hopes of keeping your teeth healthy and strong, sharks are continuously growing new rows of triangular teeth that need no jawbone to keep them in place. They are entrenched in the flesh.
Several rows of these teeth are patiently killing time (and whatever else they choose to kill) behind the current row of teeth. A sharks main row of teeth is usually replaced in a mere 8 days! Absolutely no brushing required! The ocean floor is literally covered with millions and millions of shark teeth.
Growing Teeth Forever - A Tooth Fairy's Dream!!
A typical shark will grow (and lose) thousands of new teeth over the course of its life. So the question is, would you brush your teeth nearly as often if you were going to have 30,000 of them over the duration of your human life? Well that's about how many a shark will have. So needless to say, he or she is not concerned with the ones left behind, or in someone's behind for that matter!
So the next time someone calls you big mouth, think about a shark's mouth and its ability to hold 300 rows of teeth with hundreds of teeth in each row, then look at them knowing they are fortunate that your mouth is actually quite small compared to a shark.
The average shark has 40-45 teeth and can have up to seven rows of replacement teeth. Because sharks lose a lot of teeth and grow them back quickly, they often go through more than 30,000 teeth in a lifetime.
