Fun Facts for Kids – 3 Examples of Wild Animal Teeth

January 2nd, 2015

The animal kingdom is full of interesting teeth! Here we have highlighted some of the weirdest teeth we could find!

1. Sharks
Sharks make their own toothpaste! Well, sort of. The surface of a shark’s tooth is made up of 100% fluoride – that stuff found in toothpaste and mouthwash that keeps your teeth healthy. That, plus the fact that sharks replace their teeth regularly, means they never get cavities. So does that mean that sharks have probably the healthiest mouths in the animal kingdom?

2. Seals
The Crabeater seal lives in Antarctica and is one of the most common types of seal. Despite its name, the Crabeater seal does not eat crab! Instead it eats Antarctic krill (a small type of crustacean that swims in large groups), which it filters through its wild-looking lobed teeth. The seals swim through schools of krill with their mouth open then sieve the water out through their specially designed teeth and leave the tasty krill behind for the seals to eat.

3. Sheep
You can tell how old a sheep is by looking at their teeth! When sheep are born they don’t have any teeth on the top of their mouths, just eight baby (or milk) teeth on their lower jaw. Instead of top front teeth, sheep have a dental pad and front and bottom molars in the back of their mouths. The baby teeth are slowly replaced as the sheep age. Looking at which of these front bottom teeth have been replaced with adult teeth can help determine if the sheep is one year old, two years old, or three. By the time they are four years old they have a full set of 32 teeth.
