We did an experiment demonstrating what can happen to a tooth if exposed to too much soda, juice or acidic foods (vinegar). We made some predictions and then we used an egg to represent the tooth. We soaked it in the different liquids for a few days then we observed them. We next brushed them with toothpaste and observed some more. Afterwards we graphed the results by coloring in the eggs on our graph. We showed what the egg originally looked like, what it looked like after soaking in the liquids for a few days, and then what it looked like after we brushed it with toothpaste. Some of the conclusions we made were that the soda was the most harmful to the tooth's color and strength. It was stained the deepest and developed a crack. It was also the most difficult to whiten. We concluded that the vinegar completely destroyed the shell of the egg (tooth). It had no external protection left and was entirely softened. We were unable to brush it without it breaking. We got internal leakage (the egg yolk started oozing). The juice was the least detrimental. It definitely caused significant staining, but it cleaned up pretty decent with toothpaste and toothbrush. It was never quite the same, but pretty decent. I really love this experiment and teaching kids the importance of brushing their teeth regularly and making good food choices not only for your body, but for your teeth as well.
