Higher:
Explore the impact of diet on dental hygiene
Middle:
Explain the function of different types of teeth
Lower:
Identify and name different types of teeth
Lesson Recap Starter: Think back to the last lesson. How does your sense of taste help to keep you safe?
Lesson Starter: What would happen to your teeth if you stopped cleaning them?
Ask children to come up with a list of issues which may arise from poor dental hygiene.
Look at the following slide to see examples of unhealthy teeth. What are the children's reactions to these pictures?
Presentation - Starter Slide
Explore the story and learn about the different types of teeth in a human's mouth and what they are used for. Look at how they help the digestion process.
Key Concept:
During this unit, each lesson contains a key concept question housed in the '30 Second Challenge' slide. To help children master this content so the knowledge moves from their short term memory to their long term memory, at the beginning of the follow on lesson the question from the previous lesson is revisited.
The questions covered during this unit include:
1. How does your sense of taste help to keep you safe?
2. What our teeth are used for?
3. Why do you think food needs to be broken down into smaller pieces?
4. Why the food pyramid is important?
5. Why are vitamins and minerals are important for your body?
6. What is a food chain? What are producers, consumers, and decomposers?

Egg Staining Experiment
In this experiment the children are going to see the effect various liquids have on teeth, and how quickly teeth can stain. Tell the children that they are using eggs for this experiment because eggshells have similar properties to teeth.
Ask the children to look at the liquids that have been gathered for the experiment, and make a prediction as to which of the liquids stain eggs the most.
Process:
1. Set up four beakers and pour the same amount of liquid in each. One liquid should be still water as this will act as a control.
2. Place an egg into each beaker. The liquid should just cover the egg.
3. Leave the experiment for 2 or three days. You can check on the eggs during this time and note any changes you see,
Remove the eggs from cup. Observe any changes and encourage children to describe them and suggest why it may have occurred.
Brush the eggs gently with the toothbrush and sample of toothpaste - you will be able to see how much the egg has been stained by the various substances and how easy it is to brush off. Use the Handout to begin recording the information.
Ask children what this makes them think about how regularly they should brush their teeth.
Questions for the children to consider:
Egg Staining Experiment
4 beakers or cups
4 different substances such as:
Cola, coffee, blackcurrant juice, water
4 eggs with shells
Toothbrushes / scrubbing brush
Toothpaste (optional)
Cups of water for rinsing
Spoons to remove egg from cups
Kitchen towels
Handout
Use the Handout to record the results of your experiment and for children to write sentences to explain what they found.
Second page of Handout is a comprehension activity on the lesson, and children can give some top tips for maintaining oral hygiene.
Quiz
With their talk partners, the children are to go through the quiz at the end of the presentation and answer the questions.

The Science behind the Science:
Humans themselves have three different types of teeth. They have incisors, canines and molars. Incisors are they to aid in biting and the chewing of the food initially. The canines are used for tearing food apart and the molars are used to crush and to grind food. As humans, we have two different sets of teeth in our lives. Milk teeth, otherwise known as baby teeth are the first set of teeth that we get as we begin to grow. A young child will have around 20 little baby teeth by the time they reach 3 years old. Permanent adult teeth start to develop when the child begins to lose their initially baby teeth. This happens at around the age of 6. As an adult, it is possible to gain around 32 permanent teeth.
It is important to brush your teeth at least twice a day, to regularly visit your dentist and to eat the right foods and the right amount. For example, too much sugar can and will cause tooth decay.
Identify the different teeth in humans and their simple functions.
