Year 4 - What stains our teeth?

Date: 11th Nov 2025 @ 10:12am

This week, we did an experiment to observe what happens to our teeth when we drink certain drinks and don't brush them. We left eggs in coke, diet coke, orange juice, milk, water, tea and coffee over the weekend. The egg shell acted as our teeth enamel, so we needed to observe whether or not the enamel could protect our teeth in various drinks. Due to the sugar content, diet coke and coke stained the worst.
