We have been finding out about teeth, so last week we started an experiment to find out how damaging different drinks could be to our teeth. We used egg shells to represent teeth because they are very similar to the material our teeth are made from and so react in a very similar way. We put egg shells into four different liquids: water, orange juice, blackcurrant cordial and cola. The results were amazing and a bit disgusting! Take a look at our photos below to see how much damage these drinks can do to your teeth.
