We have been investigating the effects of different drinks on our teeth. We submerged eggs (their shell has similar properties to the enamel on our teeth) into different liquids. We tested; water, milk, orange juice, sugar free coke, coke and vinegar. After 2 days we were amazed to see the effects of the orange juice on the egg, it had started stripping off the shell. The vinegar had made the whole egg squishy. We found that both the cokes left staining on the eggs. We reflected on which drinks are best for our teeth.
