Human Teeth VS. Animal Teeth

1st Grade Student PowerPointBy: Allison LeCoq - EDT 610

Animal TeethWhat 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

Animal TeethWhat 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?

Human TeethWhat 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

Human TeethWhat do we want to know about them?– How many are there?– Why are they shaped differently?– Why do they fall out?

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!

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!

How do animals take care of their teeth?

Pets can have their teeth cleaned at the veterinarian’s officeCrocodiles wash their teeth in the water and then sterilize them in the sunlightBy eating their prey and then chewing on the bones, animals like wolves help keep their teeth clean

How do animals take care of their teeth?

Rabbits, horses and elephants chew grasses, leaves and plants to clean their teethAnimals at the zoo have their teeth cleaned by a veterinarian Animals hardly ever get cavities even though they never go to the dentist!

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 withMeat eaters have sharper teeth called canines to catch prey and tear their food with

What We learned:Mammals are heterodonts–This means that some of our

teeth are shaped differentFish and reptile teeth are all shaped the same, but they come in different sizes

Mammal Teeth

Reptile/Fish Teeth

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

So how many teeth do humans have?

We have 2 sets– 20 baby teeth– 32 adult teethWhy 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

Our 3 types of teeth:1. Incisors– Front teeth2. Canines– Pointy teeth3. Molars– Back teeth*They are all shaped differently to

help us eat and digest food

How are animal teeth like human teeth?

1. We both use them to eat food2. We both have to clean them, just

in different ways3. Animal teeth have different

shapes like human teeth do4. We both lose our teeth5. We both use our teeth to show

emotions (angry, happy)

How are animal teeth different from human teeth?

1. Reptile and fish teeth are all shaped the same – ours are different shapes

2. We don’t use our teeth to kill prey like meat eaters do

3. Some animals have several sets of teeth (sharks, elephants), while we only have two
