Healthy drinks?

 

 

 

 

 

 

In Chestnut class we have been testing the effect of different drinks on our teeth.  As egg shells contain the same substances as teeth we placed some hard boiled eggs into water, milk, coke, coke zero, coffee and orange juice and left them for 6 days.  We observed what had happened to the eggs and discovered that milk and water are the best drinks for our teeth.  We were surprised by how much damage the orange juice caused and now know that we must remember to clean out teeth after drinking orange juice.
