How can we look after our teeth?

img_3854We checked up on our teeth experiment this week!  We started by placing a hard boiled egg into a cup of water, another egg into some coffee and a final egg into some coca cola.  We then made some predictions as to what would happen to the eggs.  This week when we checked the eggs, we found that the best thing for us to drink that will not affect our teeth badly is the water (the egg had not changed at all).  The coffee made the egg go really brown and the coca cola made the egg shell go rough.  We then had a go at brushing the discoloured eggs with toothpaste to make them clean again!
