Which kinds of drink stain teeth?
Transcript of Which kinds of drink stain teeth?
1. Fill three separate large containers with coffee, tea, and cola.
2. Put at least one hollowed-out eggshell into each container.
3. Every day, fish them out and observe the progress of discoloration.
4. Take some photos of gradual changes. On the day when you really start to notice discoloration, note that day.
5. Record your results and compare the effects of the three liquids.
My hypothesis was correct, the coke was the dirtiest because of it's coloring and so much sugar and caffeine in it. So Coke could really be bad for your teeth, don't drink it all the time.
My question is that, how long it takes to stain egg shells with coffee, tea, and cola.
I think that the Coke will make the
egg dirtiest because it has more
caffeine and coloring.
Teeth are structures in the mouth that are individually squares or cubical-shaped with grooves intended for use in breaking down food for consumption. Teeth are naturally white or off-white in color, but build-up from foods and drinks such as coffee and tea over time can stain the white color and turn teeth yellowish and discolored. In this experiment, we'll use egg shells in order to explore how teeth are stained by drinking coffee, tea, and cola.
