Did you know?
1. Sharks have numerous rows of teeth.
Shark teeth are arranged in rows. The number of rows varies from species to species, sharks often have anywhere from 5 to 15 rows of teeth per jaw, with the bull shark having around 50 rows of teeth!
2. Shark teeth are loosely connected and fall out frequently.
Shark teeth are attached to gums by soft tissue, instead of a root (like our teeth), and they fall out often! When teeth are worn or broken, new, sharper teeth can replace them.
3. Sharks continue producing teeth throughout their lifetime.
Sharks arecontinually producing teeth to replace those lost. Each time a shark loses a tooth in one of the rows, the tooth behind it moves forward — acting as a conveyor belt. In fact, a shark may produce over 20,000 teeth in its lifetime!
4. Shark teeth have built-in toothpaste.
The outside of sharks teeth is made up of fluoride! Fluoride is nature’s cavity fighter and can be found in all ADA accepted toothpaste.
