With two white eggs, a cup of water, a cup of coke, and toothbrush and toothpaste; we were able to see the effects sugar have on our teeth.
We left each egg in either water or coke, overnight. The next day, the one taht had been in the soday was brown. After taking turns to brush it with the toothpaste, most of the brown was removed. But, some stained the egg. This is similiar to our teeth. If we drink too much soda (or have too much sugar for that matter), and are not careful about brushing, our teeth can get discolored.
