After watching this clip, children could be asked to consider the difference between milk teeth and adult teeth. Through discussion it could be established that, unlike a shark, our bodies cannot replace an adult tooth once it is lost. This information could be used as a prompt to discuss with the children the factors which contribute to keeping our teeth healthy. By comparing our own teeth to that of a shark, this clip could also be used to introduce children to the idea that different animals have different types of teeth due to the varied diets they eat.
