If you smile at yourself in the mirror, or if you just run your tongue along your teeth, it's obvious that they aren't all the same.
You have sharp teeth, shaped like little chisels, at the front of your mouth.
Alongside them are teeth that are more pointed, and at the back of your mouth there are some big flat-topped teeth.
So what's good about having all these different teeth? Why not just have a mouth full of little pointy teeth, like a crocodile, for instance?
The type of teeth we have is suited to the type of food we eat. Each tooth type lets us deal with food in different ways.
Use this activity to test yourself on what you know about your teeth and what they do.
