In honor of Shark Week returning to Discovery Channel on Sunday, August 10th, sink your teeth into these 10 facts about shark teeth.  

1. Shark teeth are not attached to gums on a root like our teeth.
2. Sharks typically lose at least one tooth per week because they may become stuck in prey or broken and forced out.
3. Shark teeth are arranged in neat conveyor belt rows and can be replaced within a day of losing one.  Sharks average about 15 rows of teeth in each jaw. 
4. Shark teeth are popularly found as beach treasures because sharks shed 1000s of teeth in a lifetime. Although, don’t get yourself in trouble if you decide to collect them. Shark teeth are an illegal import. 
5. Well after a shark dies and its body decomposes its teeth will fossilize.
6. Sharks are born with complete sets of teeth and swim away from their mother to fend for themselves.  
7. A shark’s tooth shape is dependent upon its diet and were recently discovered to contain flouride.
8. The inside of shark and human teeth contains a soft mineral known as dentin.
9. Sharks do not suffer from cavities as the coating of shark teeth is acid resistant and less water soluble than our teeth.
10. Shark teeth and human teeth are equally as hard.
