Jaw Model and Giant Teeth

Introduction
Public summary: 

An enlarged model of the jaw with some giant teeth that can be opened up. Find out why we have milk teeth, why there are different types of teeth and why different species have different teeth.

Anatomical model of the half jaw, parts can be removed to show structure of the teeth.

Packing Away:

Explanation
Explanation: 

ACTIVITIES:
-show whole model- what do they think it is? Let them point to their own jaws
-take the model apart; any ideas what individual bits are?

OTHER THINGS TO TALK ABOUT:
-losing teeth; getting new ones (especially when the kids are at that age)
- teeth are different- why do you need different shaped teeth? If we've got the animal skulls out, you could get them to go and have a look at those afterwards and think about why different animals have differently-shaped teeth.
- toothache- look at nerves coming into teeth- that's how you can feel pain

TIPS FOR DEMONSTRATING:
-focus your explanation on the age of the audience; if you have 6/7 year olds that are just getting their adult teeth, talk about that; if you have teenagers, you could talk about braces etc.

BASIC PROCEDURE AND EXPLANATION:

- Compare model to skull so they know what they're looking at. How the jaw bone fits onto the skull so we can open and close it to speek, eat etc. Let them feel the joint on themselves by putting their fingers on the sides of their head just in front of ear, moving their jaw around. Explain how it can slide forward so we can open our mouths further.

- Different types of teeth have different functions. Flat ones at the front for cutting things, pointy ones for tearing/ripping, flat big ones at the back for grinding. When do we get new teeth? baby ones, adult ones, wisdom teeth. Look how deep the teeth go into our gums, can see on skull X-ray too.

- See where the blood vessels and nerves go to teeth. Think about what nerves are doing, funny that they go to bones. When do we know about them being there...toothache. Why might we get it? Protection covering teeth damaged, sugar, bacteria and stuff.

OTHER THINGS TO TALK ABOUT:

- medical procedures on teeth: fillings, braces, dentures; the idea is to get them thinking about what could go wrong and how they would fix it if they were a dentist

Hazard Risk Likelihood Severity Overall Mitigation Likelihood Severity Overall
Tripping over Loose Teeth from Model Teeth are quite large and could represent a tripping hazard if on the floor 2 3 6 If teeth fall on the floor, stop the demonstration and pick up the teeth as soon as is safe. Warn anyone who is walking nearby about the teeth on the floor. 1 3 3
