In science we have been looking at the layers of teeth including the enamel, pulp and the dentin. We have then thought about what can cause tooth decay and have been looking at the effects of not caring for your teeth. 

This week we have been investigating, with eggshells which liquid is best for your teeth and causes the least amount of damage and decay. We have tested coke, water, vinegar, milk and orange juice and observing these over the upcoming week. Which one do you think will be the best?
