Here are some terms you should revise.
Each of these terms comes with a brief explanation.
I have grouped them into different parts of science that you study.

Today we are going to look at Teeth.
Teeth are really important and should be looked after (if you want to keep them). You can look after your teeth by doing the following 3 things:

1. Visit your dentist regularly.
2. Brush your teeth properly twice a day and floss.
3. Don't eat too many sugary foods or drinks.

You will have two sets of teeth in your lifetime. Your first set are often called milk teeth. These teeth fall out from around the age of 7 or 8 and are replaced with adult teeth.

Adults have 32 teeth. Your gums support all your teeth.

These teeth are grouped into 4 types. Each type of tooth does a different task.
Here are the four types with what they do:

Incisors CUT
Canines TEAR
Pre-molars CHEW
Molars CHEW
(Sounds like a train: cut, tear, chew chew).

After eating, your teeth will be attacked by bacteria. These bacteria build up and coat the teeth in a white substance. This substance is called plaque.
Plaque attacks the white visible part of the teeth called enamel.
If you get a hole (cavity) in the enamel you will need to go to the dentist and have a filling.

That is about it for now. Here is a table to see what you can remember. See if you can complete it.
