Different types of teeth have different functions, but work together to break down food to travel through the body.
Incisors are sharp and flat, and are used to cut and bite food.
Canines are sharp and more pointed, and are used to rip and tear food.
Molars are wide and bumpy, and are used to chew and grind food.

Common misconception

Children may think that all teeth are the same and that they perform the same job to break down food in exactly the same way.

Eating a few different types of food (Task A) will help children to see for themselves which teeth they are using and what they are actually doing to break down food in different ways.
