Smile! What do you see? A mouth, lips
and teeth. Teeth help us to bite into our
food and cut it up into smaller lumps.
Different shaped teeth have different
jobs. Some are shaped like spades and
we use them to bite into food. Some are
sharp and pointed, so as to shred the
lumps of food into smaller bits. Then
there are wide, flat teeth at the back of
the mouth, which mash the food into a
pulp.
When we are born, we have no teeth
that can be seen yet. The teeth are all
hidden under our gums. When they
start to develop, they can make the
gums sore. This is called teething.
We have more than one set of teeth.
As small children, we get a set of milk
teeth. There are only twenty of these
milk teeth. They start to wobble and
fall out when we are about six or seven.
Then we get our next set of teeth. These
adult teeth are much bigger and are all
we get for the rest of our lives. So it is
very important to keep them healthy.
Inside the mouth,
it is dark and wet.
There are some living things so small
that we cannot see them. They like dark
and wetness, so they live and breed
inside our mouths.
If they breed on food which has stuck
to our teeth, the teeth can rot and go
bad.
Brushing our teeth can help stop this
happening. This is why teeth need to be
brushed when you get up in the
morning and before you go to bed.
Brush the inside, outside and top of the
teeth.
Some food is good for teeth.
apples
milk
cheese
Some food is bad for teeth.
chocolate
lemonade
lollipops
Dentists are trained to help us protect
our teeth and gums. They have lots of
different equipment.
Dentists have a lamp, which they shine
into the mouth so they can see it
better. Then they use a small mirror to
help them see all the teeth. They poke
around with a sort of metal toothpick,
which helps them look for holes.
If a tooth has a hole in it, it needs a
filling to stop the rot spreading. The
dentist starts by injecting a painkiller
into the gum to make it numb. Then the
dentist drills out the rotten part of the
tooth. The hole that is left is called a
cavity, and this is what the dentist fills.
A tooth is made up of three main parts.
It has a root, which joins it to the gum
and to the rest of the skull. Then, on
the inside, there are lots of nerves. It is
the nerves which sometimes feel pain.
The outside of the tooth is coated with
white enamel, which is very hard.
Different animals have different sorts of
teeth. Animals' teeth have adapted to
do all sorts of different jobs. Tusks are
the biggest sort of teeth.
Animals such as rabbits, squirrels,
lemmings and muskrats have long,
strong teeth. These teeth keep on getting
bigger and must be used often or they
will get too long. Pet rabbits sometimes
have to have long teeth filed down by a
vet if they have not nibbled much hard
food.
Sharks have very sharp, pointed teeth
They develop teeth all the time. So if
one tooth drops or falls out, they have
a second one waiting to fill the gap. So
sharks never run out of teeth!
