2. Animal Teeth What do we know about them? They can be sharp and pointy
They help with eating and catching prey
Animals don’t have to go to the dentist like people do

3. Animal Teeth What do we want to know about them?
Do they fall out like ours do?
How do they take care of them?
Do all animals have the same teeth?
Which animal has the biggest teeth?
How are they like our teeth?

4. Human Teeth What do we know about them?
They need to be brushed and flossed everyday
They help with eating and chewing
They fall out and grow back in

5. Human Teeth What do we want to know about them? How many are there?
Why are they shaped differently?
Why do they fall out?

6. Do animal teeth fall out?
YES!
Some animals like cats and dogs have 2 sets of teeth. The baby teeth fall out and are replaced by the adult teeth
Other animals, like elephants, have several sets of teeth that fall out all the time!

7. Did You Know?
Sharks can lose their teeth every two weeks to replace worn or broken ones?
Beavers, guinea pigs and rabbits have front teeth (incisors) that never stop growing?
Alligators have a total of 80 teeth that fall out and grow back in all the time!

8. How do animals take care of their teeth?
Pets can have their teeth cleaned at the veterinarian’s office
Crocodiles wash their teeth in the water and then sterilize them in the sunlight
By eating their prey and then chewing on the bones, animals like wolves help keep their teeth clean

9. How do animals take care of their teeth?
Rabbits, horses and elephants chew grasses, leaves and plants to clean their teeth
Animals at the zoo have their teeth cleaned by a veterinarian
Animals hardly ever get cavities even though they never go to the dentist!

10. Do all animals have the same teeth?
No!
It depends on the animal and what they eat.
Plant eaters have more flat teeth called molars to chew and grind with
Meat eaters have sharper teeth called canines to catch prey and tear their food with

11. What We learned: Mammals are heterodonts
This means that some of our teeth are shaped different
Fish and reptile teeth are all shaped the same, but they come in different sizes

12. Mammal Teeth

13. Reptile/Fish Teeth

14. Which animal has the biggest teeth?
The elephant does!!!
Their tusks are really long teeth called incisors
Can grow to 10 feet long
Can weigh Up to 200 pounds

15. So how many teeth do humans have?
We have 2 sets
20 baby teeth
32 adult teeth
Why do they fall out?
Just like some animals, we are born with two sets of teeth
The baby teeth fall out so the adult teeth can grow in

16. Our 3 types of teeth: Incisors Front teeth 2. Canines Pointy teeth
Molars
Back teeth
*They are all shaped differently to help us eat and digest food

17. How are animal teeth like human teeth?
We both use them to eat food
We both have to clean them, just in different ways
Animal teeth have different shapes like human teeth do
We both lose our teeth
We both use our teeth to show emotions (angry, happy)

18. How are animal teeth different from human teeth?
Reptile and fish teeth are all shaped the same – ours are different shapes
We don’t use our teeth to kill prey like meat eaters do
Some animals have several sets of teeth (sharks, elephants), while we only have two
